Garden

How to make a walk-behind tractor using the example of a project from В

To cultivate a site with a large area on which a significant part of the territory is reserved for the garden, using only improvised tools is not an easy task. Work on loosening, digging, and also weeding the garden manually takes a lot of time and effort. It is good when there is an opportunity to purchase a walk-behind tractor, which will become an indispensable assistant on the site. But to facilitate work on the ground, you can and making a walk-behind tractor with your own hands.

What can you build on your own?

The factory-made motoblocks market offers customers a fairly wide range of products for every taste. However, the prices for such agricultural machinery can not be overcome by many. Therefore, in vegetable gardens in rural areas, you can often find a home-made walk-behind tractor, which is almost as good as a factory analogue in operational parameters.

Creating universal designs, craftsmen most often use parts of old motorcycles and scrap metal

Morally obsolete models of motorcycles often serve as the basis for the manufacture of various home-made products and small-scale mechanization tools useful in the household.

Since self-made motoblocks are often created from improvised old materials, the Druzhba motor, known to many, is often used as the engine of the unit.

On the basis of self-made motoblocks, craftsmen create tools no less significant in agriculture, for example: plows, as well as hillers for hilling corn or potatoes

One of these masters is the inventor Valentin Arkhipov, who is the author of the manufacture of a number of useful devices and the construction of all kinds of household equipment.

A talented designer created a multifunctional device with which you can not only plow and harrow the land, but also plant, cultivate tuber crops, as well as harvest and rake tops

Therefore, when thinking about how to make a walk-behind tractor with your own hands, it is better to opt for this proven and successfully used option. Anyone can handle a simple and easy to use agricultural unit.

Does it make sense to make a homemade walk-behind tractor?

The indisputable advantage of home-made walk-behind tractors is their price, which is practically absent. Consumables are either already initially on the farm from a masterful owner, or purchased from neighbors for a nominal fee. Motor-blocks are assembled from parts of old chainsaws, mopeds, motorcycles, agricultural machinery. Despite this, the end result is often above all praise. In terms of reliability, functionality and convenience, such machines are not inferior to factory counterparts.

A home-made walk-behind tractor, the main elements of which are taken from the old Minsk motorcycle

We suggest you evaluate the simplicity of the device of a rather well-known home-made walk-behind tractor, designed by Kaluga craftsman V. Arkhipov. Data on how to make a walk-behind tractor according to Arkhipov’s project was published for the first time in 1982 in the magazine Modeler-Designer. The project has gained immense popularity, has been recognized by professional designers and craftsmen. We can say that even now Arkhipov’s invention is an example of an ideal home-made walk-behind tractor with many useful functions.

Homemade Arkhipov walk-behind tractor combines the simplest structure, high functionality and reliability

The main structural elements of the Arkhipov walk-behind tractor

Arkhipov's motoblock is a gas-powered car with a boot for carrying goods and a suspension for agricultural implements (plow, cultivator, harrow, rake, etc.). The main element that ensures the operation of the unit is the engine. In the original project of Arkhipov, the VP-150M motor (7 hp) was used, taken from the Vyatka scooter. It can be replaced, for example, with the T200M engine (9 hp) of the Tula-Tourist scooter or the T200A of the Muravei scooter (14-16 hp). A feature of these engines is high power and an integrated air cooling system that allows the cylinder head not to warm up when operating at low speeds and heavy load. A motor without a cooling system in such conditions will inevitably overheat, which will lead to its rapid breakdown.

General view of Arkhipov walk-behind tractor (click to enlarge)

Most of the other elements of the walk-behind tractor are also taken from the scooter: part of the frame and suspension of the motor, chains, control cables and handles. Chains are used in increments of 12.7 mm and 15.9 mm. The number of teeth of the sprockets of the output shaft is 11, the running axis is 12, the secondary shaft is 20 and 60.

The remaining parts are made independently. The wheel axle is machined from the fittings, the U-shaped frame and the trunk are made of pipes with a diameter of Ø60 mm by welding.

The design of the frame of a self-made motoblock Arkhipova

Trunk device from pipes (you can use a corner)

To connect the body of the motoblock with the steering wheel and the plow, the design provides for the use of three hinges of the regulating and main thrust. The gearshift device is also made independently. A steel pipe is welded to the frame of the walk-behind tractor, an axis is provided at the end of which. A swinging rocker is used on it, which is used to tension the gear cables going to the gearbox. A piece of pipe, which is used as a gearshift knob, is welded to the beam.

An important feature of the Arkhipov walk-behind tractor is unusual running wheels, round and flat, resembling circular saw blades. Only instead of teeth they have grousers. Such wheels adhere well to the soil; they do not compact it during passage. On the contrary, when the lugs rotate, additional loosening of the beds occurs. The wheels are cut from sheet steel S = 10-12 mm using a gas cutter. Lugs are performed in accordance with the drawings. Instead of such wheels, ordinary car tires are also suitable for a motoblock, but they will have less traction with the soil and therefore slip during operation of the motoblock.

Lugged metal wheel

Assembly technology for elements of such a walk-behind tractor:

  1. An asterisk is welded onto the running shaft, housings with bearings No. 307 and No. 308, overrunning couplings acting as a differential, are installed.
  2. Mount the running wheels and frame.
  3. Telescopic traction, steering wheel and plow are fixed on the frame.
  4. Two arcuate pipes from the scooter frame connect the frame of the walk-behind tractor with a part of the engine mount.
  5. Install the fuel tank by placing it between the pipes.
  6. A bracket is welded to the frame, at the end of which a steel axis Ø36 mm, 15 cm long, is transversely arranged.
  7. A gasoline engine with a suspension bracket is mounted on the axle, and then fixed to the side curved tubes of the frame.
  8. According to the drawings set the secondary shaft.
  9. Stretch control cables and chains.

Travel shaft assembly

Some features of working with such an aggregate

Working with a homemade Arkhipov walk-behind tractor is easy and convenient. This is primarily due to the use of articulation between the tractor and the processing canopies. The rigid connection used in most agricultural home-made models makes rotation difficult. While the movable hinges allow you to change the direction of movement of the walk-behind tractor, without pulling the processing tool (plow, harrow) from the ground.Thus, less physical effort is spent, and the furrow remains flat.

Arkhipov's motoblock, thanks to the maneuverability and reasonableness of the design, is surprisingly easy to drive

The depth of plowing is maintained constant without additional efforts of the operator of the walk-behind tractor. There is no need to lower or raise the plow; just change its angle of inclination with respect to the work surface. If the plow suddenly begins to go deeper into the furrow more than it should be, then the lifting force from the field board automatically starts acting on it. If the ploughshare rises from the furrow, then its angle of attack increases, plowing the plow back into the soil. This ensures a stable furrow depth and balance of the unit itself.

[include title = "YAN - in the text"]

During the operation of a conventional home-made walk-behind tractor, the plow often pushes to the side due to the considerable resistance of the plowed soil. The plowman has to make an effort to keep a straight line of the furrow. Arkhipov's motoblock is devoid of this drawback, since the axis of the plow is inclined to the direction of movement. When plowing, the unit is slightly turned to the left and this compensates for a possible skid.

Plowing the first furrow is the most responsible action. It should turn out perfectly smooth, and for this, the direction of movement has to be set by the plow itself, rigidly connected to the control handles. By turning them, the operator changes the direction of movement. For example, if you want to turn the unit to the right, then you need to tilt the handles to the left. The plow fixed in the ground will not be able to shift to the left, it is held in one position, so the rod turns the car to the right. When plowing the following furrows, the management is much easier, since the wheel will pass along the plowed furrow, copying its direction.

We arrange canopies and additional functions

Homemade Arkhipov walk-behind tractor can become a reliable assistant in the work on the land. As a processing tool for it, not only a plow is used, but also a cultivating cutter, harrow, rake. All these tools are fixed to the tractor with two bolts, just like a plow.

For planting potatoes, you can use the cultivator, having previously removed the dumps from it. Having fixed it on the motor-block, furrows are carried out. After the tubers are laid, the dumps on the cultivator are put back and pass between the furrows. Dig the grown crop using a special potato digger. Potato tops, mowed grass or weeds can be removed with a rake canopy.

Potato digger, plow, spade blade - all this can be used as attachments for a home-made walk-behind tractor

In addition to land work, the Arkhipov walk-behind tractor can also be adapted for cleaning the site. For example, securing a bulldozer knife on a machine, we get an effective snow blower. And installing a roller with a brush and an additional sprocket is an excellent “electric broom” for sweeping garden paths.

Arkhipov's motoblock is a device that will successfully replace you with an expensive factory-made unit. He will cope with his role 100%: it will allow you to cultivate the land as soon as possible and save you from hard physical labor.

In addition to the Arkhipov walk-behind tractor, there are many other home-made models. Look at the operation of one such unit with a mounted potato digger - this is a truly ingenious invention, the device of which is shown in sufficient detail in the video:

Unit design features

The motor-block device is a two-wheeled self-propelled machine equipped with an engine removed from the VP-150M scooter. The reason for choosing this particular engine was the fact that it has such a constructive solution, due to which forced cooling of the cylinder head by air is carried out.

Such a motor from a scooter is able to operate at the lowest speeds at fairly high loads

For the construction of the motoblock, the master used control cables taken from the scooter, engine mounts, as well as a double arc of the frame, handle and chain. The remaining structural details were industrial production

Separately, the designer manufactured a U-shaped frame welded from pipes and a wheel axle machined on a lathe. He also made 3 homemade joints for the main and control rods. They will be used as connecting elements between the walk-behind tractor, its steering wheel and plow.

A steel pipe is attached to the unit’s frame by welding, ending with an axis, which is necessary for tensioning the cables going to the engine gearbox. The tension itself is carried out by means of a rocking beam, the gearshift knob of which is a welded piece of steel pipe.

The pitch of the chains used to create the device is 12.7 mm and 15.9 mm. The number of teeth of the sprockets: the output shaft is 11, the secondary shaft is 20 and 60, the axle is 40.

What exactly is this design good for?

There are more than a dozen analogs of such a model, but in comparison with them the original model of the Kaluga master walk-behind tractor has a number of undeniable advantages.

  • Swivel joint. Processing tools and tractors of most of these models have a rigid connection, which complicates the maneuvering of the unit and thereby complicates the work with it. The details of this agricultural unit are connected by hinges. This makes it possible in the process of work, if necessary, to change the direction of movement without removing the plow from the furrow.
  • The offset of the axis to the direction of travel. Many owners, when processing soil using a walk-behind tractor, were faced with such difficulty that, in the process of moving forward under the influence of soil resistance, the unit leads to the side. To align the furrows, a lot of effort should be made. To compensate for such a skid, the master placed the axis of the plow at a slight angle in the direction of movement. When plowing, the construction is slightly turned to the left. The desired position can always be adjusted with three traction joints.
  • The level of a given depth of plowing. If in other models the plowing depth is maintained by lowering or raising the plow, then when working with this walk-behind tractor it is performed automatically. Regulation is carried out by changing the angle of the plow with respect to the furrow. The design is equipped with a field board, which acts as a lifting force when burying a plow. If, on the contrary, the ploughshare appears above the surface of the earth, then its angle of attack instantly increases, under the influence of which it again plunges into the soil to a predetermined depth.

Step-by-step device assembly technology

Assembly of the structure begins with the arrangement of the running shaft. For this, a housing with bearings is attached to it, an asterisk is welded, and overrunning couplings are mounted, which in the process of work will carry out the function of the differential. After that, the design is equipped with wheels and a frame. A telescopic rod, a plow and a steering wheel are mounted on a fixed frame.

The main elements of the running shaft: 1 - shaft, 2 - sprocket, 3 - cover, 4 - bearing housing, 5 - bearing pad, 6 - bearing No. 308, 7 - overrunning clutch housing, 8 - axis of the dog, 9 - dog, 10 - ratchet, 11 - bearing No. 307, 12 - washers, 13 - wheel, 14 - dog spring

Agricultural walk-behind tractor is equipped with special wheels, which, unlike rubber counterparts, are able to provide better traction.

Such metal wheels are not clogged with earth. In contact with the soil, they do not compact it, but rather loosen it

Two arcuate pipes are used to connect the unit frame with the engine mount and the frame of the scooter itself.Between them there is a place for a fuel tank.

To equip the engine, a bracket is used, ending with a steel axis 150 mm long. The bracket is welded cantilever to the U-shaped frame of the structure. A motor with suspension is suspended on the axis itself. The assembled structure is connected to the arcuate arches of the frame. Only after this is the secondary shaft mounted, the control cables pulled and the chains pulled.

The main elements of the control unit: 1 - connecting axis, 2 - strap, 3 - pipe, 4 - handles

Connecting structural elements: 1 - main rod, 2 - control rod

Assembling a homemade walk-behind tractor.

On the running shaft are installed: an asterisk (it is welded), a housing with bearings, freewheels, acting as a differential, wheels, then a frame. A telescopic rod with a steering wheel and a plow is attached to the frame.

Now about the wheels. Thanks to their special shape, they adhere better to the soil and are not clogged with soil. Unlike rubber, these wheels practically do not compact the soil, but, on the contrary, loosen it.

Two arcuate pipes from the scooter frame connect the engine mount part and the motor block frame. Between the pipes there is a tank with fuel.

Queue for the engine. An arm with a transverse steel axis 0 36 and a length of 150 mm at the end is cantially welded to the U-shaped frame on the left. The engine, together with the suspension, is hung on this axis and attached to the arcuate tubes of the frame. The secondary shaft is installed in its place, and the chains are pulled. Control cables are pulled.

Compared to other structures of this type, the Arkhipov walk-behind tractor has a number of design advantages. Before him, tractors and processing tools were connected rigidly among themselves, which made it difficult to turn. Arkhipov, on the other hand, came up with a joint that allows you to “hold” the furrow or change the direction of movement within small limits without removing the plow from the ground.

Fig. 9. Connecting elements:
1 - main thrust, 2 - regulatory thrust.

This element also provides another advantage - the constancy of a given plowing depth without the use of additional effort. The necessary depth of plowing is supported not by raising and lowering the plow, but by changing its angle with respect to the furrow, which happens automatically: if the plow begins to dig, then the lifting force created by the field board acts on it, if the ploughshare comes out of the soil, its angle of attack increases, and it is again buried in the soil to a predetermined depth, providing a stable balance.

During operation, the plow, overcoming the resistance of the soil, often puts aside, and the plowman working with a rigid plow has to make considerable efforts to level the furrow. Arkhipov eliminated this inconvenience: the axis of his plow is located at some angle to the direction of movement. This position is regulated by three traction joints. When plowing, the walk-behind tractor is slightly turned to the left, which compensates for skidding.

When carrying out the first furrow (the most crucial moment), the plow itself needs to maintain a direct direction, because the control levers are rigidly connected to it, and not to the walk-behind tractor. When they are rotated with little effort, the entire device changes its direction of movement. Suppose you need to turn right. Plowman deflects arms at. opposite side. And since the plow cannot move there - it is as if fixed in the ground, then the traction, following the handles, turns the walk-behind tractor to the right.
On the second and subsequent furrows, control is simplified, since the right wheel goes along the furrow like a copier.

The cultivator, the harrow and the rake are set with the regulating rod exactly in the middle of the rut. Fasten with the same two bolts as the plow. The brackets of these guns are slightly deployed in a vertical plane to compensate for the angle at which the plow was mounted. The bracket is welded to the harrow vertically in the middle. A plowman can control such a harrow during movement, dropping one edge or another edge if necessary and breaking up large clods of earth.

On uneven ground, the harrow does not respond to various inclinations of the walk-behind tractor. (And with a tight connection with him, she copies them, leaving flaws).
For planting potatoes Arkhipov uses a cultivator with removed dumps. Having set it in place of the plow, he draws furrows in the ground and lays tubers in them. Then he puts the dumps in place and smells the tubers, releasing the cultivator between the furrows. In the same way sprouted plantings spud.

The cultivator can dig and plow crops. The capture width is changed by dumps.

The tops left after harvesting, as well as the missing potatoes, are harvested with a harrow or rake. By the way, it’s convenient to rake, by rake, in the heaps of the cut grass.

In addition to agricultural work, the Arkhipov walk-behind tractor is used, in particular, for snow removal. Additionally, only a small bulldozer knife is installed. You can sweep the sidewalk with an extra sprocket and a roller with a round brush.

The best design of a do-it-yourself walk-behind tractor

Homemade Arkhipov walk-behind tractor It has a very simple, but at the same time convenient and reliable design, time-tested (designed in the 1980s). But, despite its simplicity, it has several advantages: thanks to the articulated telescopic connection of the power plant and the plow, harrow or other processing tools, the walk-behind tractor is easy to control (even a child can handle it). Because to change the direction of movement it is not necessary to pull the plow out of the soil, with a little effort to give the desired direction to the walk-behind tractor itself. Of course, it was done with a bias on plowing, but they can also harrow, cultivate, plant and dig potatoes and even carry goods on the trunk. The special design of the plow and the specific scheme of its attachment make it possible to plow the land without special physical exertion. Plow for a homemade walk-behind tractor equipped with a field board, which does not allow him to fall more than the established depth of plowing, and the angle of attack will not allow him to go to the ground. The displacement of the axis of the plow slightly to the left through the design of its fastening compensates for the lateral force that occurs when working on other walk-behind tractors, leading them to the side from the direction of plowing. Motoblock construction scheme saturated with thoughtful features of the device, especially in the details. The choice of the engine (from the VP-150M scooter) is due to the presence of forced air cooling, which prevents overheating at low speeds and increases the durability of its work. Used original wheel design It allows you to loosen and cultivate the soil during the movement of the walk-behind tractor and is quite simple for making it yourself at home (the wheels are easy to cut from steel sheet with a thickness of 8-10 mm). Such simple but well-tuned solutions in motoblock device Arkhipov made him one of the best for DIY, versatile and easy to assemble, very convenient to use and reliable in use.

The best motor-block for a site to 10 hundred parts

The article talks about the difference between a walk-behind tractor and a cultivator, the principle of choosing a walk-behind tractor, as well as the benefits of choosing a Russian brand. The best walk-behind tractors for a plot of up to 10 acres are compared in terms of power and other characteristics. An example of a video about motor blocks of the Neva brand is given. The result is a model of the best and most reliable walk-behind tractor and the profitability of such a choice.

How can I upgrade a homemade walk-behind tractor?

Arkhipov's motoblock is multifunctional. It can be used as a plow or cultivator. To do this, it is enough to replace removable parts for the plow with parts with removed dumps for the cultivator. The walk-behind tractor will deepen the furrows into the ground and lay potato tubers in them. To smell tubers, you just need to install the dumps in place and walk the unit between the rows planted.

By the same principle, sprouted plants can also be spudded. You can learn more about how to independently construct a hiller for a walk-behind tractor from the material: https://diz-cafe.com/tech/okuchnik-svoimi-rukami.html

The agricultural unit is also convenient for harvesting. Using different dumps, you can change the width of the grip. The unit is also good because it is able to collect missed potatoes and the tops of plants remaining after harvesting. For these purposes, it is equipped with a rake or harrow.

The universal design can be used not only for agricultural work. In the winter, it is successfully used for snow removal. A faithful assistant will come in handy for cleaning the paths of the house territory. By installing a roller with a round brush and an additional sprocket on the walk-behind tractor, the owner will facilitate the work of cleaning the sidewalks.

DIY do-it-yourself walk-behind tractor

Land treatment requires tremendous physical effort. The need to use special equipment is obvious. The owner of the land becomes a choice: to buy or rent special equipment? An alternative is to make a walk-behind tractor with your own hands.

An acceptable option that looks extravagant, but will help save money and at the same time get a home-made walk-behind tractor that will facilitate the implementation of agricultural work.

How to make a walk-behind tractor and attachments to it with your own hands

Manually cultivate land for a long and time-consuming, it is better to take in the assistants a mechanical device - a walk-behind tractor or a cultivator. It can be purchased at the store, as well as made by hand. To buy a factory device you will need a lot of money, but homemade work will cost much cheaper, but of course it will require a lot of free time.

To assemble it and, as a result, get full-fledged small-sized agricultural machinery, you will need components, tools, basic skills and, of course, patience.

Preparing to create a homemade

To make a homemade agricultural machine - craftsmen use improvised materials and outdated components of motorcycles. So, the basis of a motoblock is often a chainsaw, scooter or moped, and when you need to get a powerful and more functional unit - an outdated model of a motorcycle (Sunrise, Java, Minsk).

Before proceeding with the assembly of a walk-behind tractor or a cultivator, they watch thematic videos on the Internet, look for the necessary information in magazines and other publications. Then they prepare the tool and material, develop sketches and drawings, which clearly depict all the functioning organs of the homemade product, including the power and chassis, control and aggregation systems. The drawing below shows what the standard design of a one-wheel motor cultivator looks like.

Fig. 1. Homemade cultivator device

1– power unit of the cultivator, 2– metal protective cover, 3– fuel tank, 4– ignition reel, 5– commutator, 6– stud fixing the tilt of the hitch, 7– bolt М-16, 8– axis for mounting the hinge, 9– mounted plow, 10– bracket, 11– bed, 12– handles, wheel with grip.

It will be useful to make the kinematic scheme of homemade work, reflecting in it the order of interaction of working mechanisms and showing how the transmission is organized.

To make a lightweight cultivator or a heavier walk-behind tractor - use the following tool:

  • electric drill with a set of drills,
  • grinder and discs for metal,
  • keys (open-end wrenches, ring spanners),
  • welding machine,
  • vise.

Material for homemade work are high-strength channels, steel plates and pipes.

A home-made frame for a walk-behind tractor or a motor-cultivator is made welded, but at the same time very durable, since all component parts of the self-made will be fitted to it later. For the construction of the frame, iron pipes or channels are used.

Sometimes, to assemble a home-made walk-behind tractor or motor-cultivator, they use a converted motorcycle frame.

The front fork and other elements are cut off from the previous design so that they do not interfere with the installation of attachments on the future cultivator. A self-made mechanism for coupling the cultivator with equipment, a trailed trolley is fastened back with welding. How to make the hitch yourself, you should look at the video.

Engine

When designing a home-made motor-cultivator, some are driven by a motor scooter or moped. But to assemble a more efficient motoblock, the strength of the engine of the moped will not be enough. It will require a 16-18-horsepower diesel engine from a motorcycle. It is "customized" to the desired parameters, conducting a series of alterations.

First, they rebuild the cooling system into active air, in order to improve the technical performance of motor vehicles. This is easily done using a 12-volt electric engine with a small iron impeller. Along the way, the valve is replaced with a flap valve, which helps to facilitate start-up, increase traction and reduce fuel consumption.

The prepared engine is mounted in rigid clamps. They are pre-welded to the front of the homemade frame, then securely tightened with bolts (the whole process is well shown in the video).

Be sure to make sure that the clamps cover the neck of the output shaft of the diesel engine of the motoblock and hold it firmly.

A lever is attached to the manual gearbox of the homemade device, which is easy to make from an iron bar by welding a ball at the end. The length of the handle is left such that, being behind the control levers of a walk-behind tractor or a cultivator, you can easily reach it.

Next, an air-purifying filter is assembled for home-made use of available materials, for example, a tin can, a metal tube. Then prepare the fuel tank of a home-made motor unit. You can make it yourself from any sealed container or take it from a broken motorized wheelchair.

Transmission

For a home-made diesel walk-behind tractor, however, like a motor cultivator, you will need chains, sprockets, a transition shaft. They are mainly borrowed from decommissioned motorcycle, auto, agricultural machinery. Hubs of stars are not difficult to do by yourself using pieces of iron and a lathe, since it’s easy to find a detailed drawing or video on the Internet on this topic. Ready gearbox for homemade take from any model of a moped. In the preparation of a homemade gearbox, steel plates and cylindrical disks with teeth are used.

The kinematic scheme of homemade work is created as simple as possible to ensure greater reliability of the functioning of its mechanisms. The transmission of torque from the engine to the countershaft is arranged by means of a standard roller chain with drive and driven sprockets. At the same time increase the gear ratio of the intermediate and reduce the speed of the output shaft.

Sometimes the so-called creeper reducer is included in the transmission of a walk-behind tractor or a cultivator. This is a reduction gear, which is necessary to obtain slow operating speeds (see how to assemble a creeper reducer in the video).

The installation of this device allows you to improve the management of homemade and make its operation safe for humans. The creeper is bought or assembled on their own. How to make a creeper yourself and what you need to do this, you can watch both the video and take an interest in the thematic forums organized by skilled technicians.

Chassis

Wheels with a diameter of up to 10 inches, taken from decommissioned agricultural machines, and wheelchairs, are best suited to a diesel motoblock with a creeper, produced by oneself. Sometimes they take from passenger cars, if you need to increase the patency of homemade equipment. And when the walk-behind tractor is used on heavy soils, they are replaced with iron ones (how they prove themselves in business can be seen in the video).

When creating a home-made motor cultivator, a soil milling cutter is installed instead of wheels for the possibility of digging and loosening the soil. Thanks to the use of such a soil improver, there is no tamping of the soil on which the cultivator has recently passed.

In the manufacture of the axis of the cultivator homemade recommend using a monolithic piece of steel. A welded pipe will not work, as it may not withstand the load.

Control device

The work of a home-made walk-behind tractor or motor-cultivator, like any machine, needs to be controlled. The control devices of such homemade products are usually handles - they are attached directly to the frame of the frame. They are made of two thick-walled pipes that are bent to give a convenient shape (the video demonstrates this well).

At their ends, gas handles and clutches are installed, removed, for example, from an old moped.

The levers of the manual gearbox and the kick start of the cultivator are made of a metal bar with a diameter of 10 mm. Kickstarter on homemade take out back closer to the operator, thereby facilitating the start of the diesel engine. Also in a convenient place fasten the brake and gear levers.

In a self-propelled walk-behind tractor, instead of handles, you can make a convenient steering adapter. The car steering column with a bipod or removed from a tractor is ideally suited for this. In such a mechanism, the bipod acts as a hitch, combining the cart with a homemade product. In the assembly of the steering adapter, a ball bearing is used - it allows you to make the hitch independent. The whole process of preparing a makeshift hitch is best seen in the video.

Hitch

Home-made walk-behind tractor or tiller complement all kinds of attachments. This is done in order to expand:

  • functional,
  • application area,
  • seasonality of work performed.

Thanks to the layout, you can use the homemade product in any season, even in winter, which allows you to use the equipment all year round. In addition to plowing and cultivation with attachments, they plow the land, plant and cultivate crops, dig up potatoes, as well as clean the territories and harvest hay.If, in addition to the walk-behind tractor, a towed trolley is made, it will also be able to carry out transport functions, helping to transport heavy, bulky loads. Due to the high cost of equipment for hanging, many try to make it with their own hands, using drawings, sketches, and author’s video.

Screen potato digger

Making a potato digger for homemade work begins with the preparation of the carriage body, welded from wire and thin rods. The sketch presented here will help to understand such a process (you can also use the video).


Fig. 4. Screen potato digger

A shovel made of a steel sheet and repeating the shape of the potato digger body is installed on the axis of the homemade product in front of the carriage. Behind her welded twigs, slightly bent to the bottom.

For the manufacture of a plow, a high-strength alloyed or sheet steel with a thickness of at least 3 mm is used for the cultivator.


Fig. 5. Homemade plow

First, on the basis of the drawing, a pattern is prepared and transferred to cardboard, and then to metal, after which it is cut using a grinder. The plow share is recommended to be strengthened with high-strength metal, for example, from a circular saw. The blade and stand can first be done separately, and then joined together. This design is less vulnerable and in the event of a breakdown of any element, it will be easy to replace it.

Trailer

To the finished walk-behind tractor, many try to make a home-made trailer or adapter equipped with a driver's seat.

1– holder of mounted implements, 2– console, 3– carrier, 4– footrest, 5– driver's seat, 6– frame, 7– body, 8– support beam, 9– M-8 bolt, 10– thrust ring, 11– wheel.

The frame for such a trailer is made of pipes, corners of any section. For the wheel axle, a metal rod with a diameter of 30 mm is used. The body of a homemade device can be made from boards, corrugated board or a sheet of metal 1.2-1.5 mm thick. To increase the strength, the wooden trailer in the corners is reinforced with metal plates, and made of corrugated board - complement with stiffening ribs.

Necessary materials

To begin with, we will find parts for the future home-made walk-behind tractor. Every motoblock mechanism is equipped with the following technical components:

  • engine,
  • transmission,
  • Control block,
  • creeper (gear),
  • aggregation system.

The motor is removed from an obsolete or faulty motorcycle. When choosing an engine, two-stroke engines are preferred, but this does not mean that four-stroke engines are not used to create a motoblock. A suitable option is a motor shot from an IZH PLANET motorcycle.

Transmission in motoblocks is used of several types:

  • gear (standard tractor transmission),
  • gear and worm,
  • belt-toothed-chain,
  • hydrostatic (new, expensive technical device that has recently appeared on the market).

The control unit consists of a set of levers switching speeds, a button that increases or decreases the fuel supply to the engine, and brakes.

It is required that the design be equipped with an aggregation system, which is an important structural element, connecting a home-made walk-behind tractor and do-it-yourself attachments created for it. Therefore, the bracket must be firmly attached to the supporting frame of the structure and is equipped with a power distribution device with increasing load on it.

Inexpensive device with great functionality

A home-made walk-behind tractor or a motor cultivator is an economical and very useful motor unit in the household. He is able to carry out all kinds of agricultural operations, thereby freeing a person from tedious physical labor. In the video below, you can see all the functionality of this miracle machine.

Such homemade products are applicable not only as an assistant in agricultural work.They are used with success when cleaning the local area, and in the winter time - to clear the snow. If you make a high-quality home-made walk-behind tractor or motor-cultivator, then the operational parameters of the home-made will be no worse than that of an expensive factory analogue.

Assembly tools

DIY assembly of technical components will require special skills and an understanding of the fundamentals of mechanical engineering. Special equipment required:

  • welding machine,
  • angle grinder,
  • drill,
  • key set
  • screwdrivers.

Among other things, bolts, nuts and screws are needed to mount the devices on the frame of the future walk-behind tractor.

How to make a walk-behind tractor using the example of a project from V. Arkhipov

Motoblock - a universal miracle machine that can automate most of the agrotechnical work on your site. With its help, they plow the soil, plant and dig potatoes, remove snow and even transport small loads (crops, fertilizers). Naturally, such an indispensable unit in the economy is sold in any agricultural center. And it’s not cheap. At the same time, its device is quite simple, not requiring special technical knowledge. Therefore, many self-taught masters decide to make a walk-behind tractor with their own hands.

Manufacturing a walk-behind tractor

Getting to the manufacture of walk-behind tractor:

  1. We assemble the frame: we use a welding machine, it is advisable to use solid metal. We make the structure stiff. The frame design consists of two side members, the rear ends must be bent upward, and the front ones fastened with welding. We attach a control unit with levers to the back. We connect the spars between each other with transverse slats. The front bar will play the role of a stand for the transmission and battery.
  2. The motor mount is made in the form of a slide, staples are welded to the sides, and a water pipe with a diameter of 42 mm is placed in the center. A transverse arc is attached to the middle of the formed slide, which has holes for mounting the engine and the base of the frame. A place is made in the front cross member of the frame for installing the tension chain, which ensures the operation of the gearbox.
  3. Installing the gearbox is an important element in the manufacture of a homemade walk-behind tractor. The gearbox converts torque energy to lower speeds. Typically, the gearbox is installed between the engine and the wheels. There are options for home-made walk-behind tractors, when the gearbox can be used not only to move the walk-behind tractor, but also for the operation of a drill, milling cutter, home-made air suspension, etc.
  4. We equip the engine with air cooling, use an electric motor rated for 12 volts.
  5. We put wheels not exceeding 10 inches. Spline cuts of the semi-axles transmit torque to the wheels. To improve the grip of the wheels with the ground, you can install a special bandage made of wire or chains - i.e. do lugs with your own hands.
  6. We install an exhaust system that remains unchanged. Despite the fact that it is possible to install exhaust from a motorcycle, you can make an exhaust with your own hands. You will need a pipe from which the pipe will be made, and silencing cans. The adapter between the pipe and the silencer must be made by a turner, it is impossible to make this attachment unit yourself.
  7. We are preparing a place for the fuel tank, which can be made with your own hands: any plastic canister with a capacity of at least 5 liters will do. A hole is made in the canister and a special hose is discharged through which fuel will be transported.
  8. We connect the units and components with each other and start the walk-behind tractor.

Using all the tips described above, you can independently assemble a walk-behind tractor in a fairly short time, using only improvised materials and spending a small amount of money.

How to make a walk-behind tractor? DIY step-by-step manufacturing of a walk-behind tractor

So, the process of assembling a walk-behind tractor consists of the following steps:

  1. Design, collection and preparation of materials and size drawings of the walk-behind tractor. The better the training will be, the less will have to deal with the alteration of their own mistakes.
  2. Assembly and welding of the supporting frame. Dimensions are calculated, depending on the main purpose, the frame accounts for the majority of the load, and welding should be performed with the utmost quality, and the pipe wall thickness should be at least 2 mm.
  3. Installation on the motor frame. An exhaust pipe and control knobs are attached to the motor, the layout of the elements is very important here, and the motor mount must be reliable enough.
  4. Preparing, installing and connecting the gearbox. This element provides the transmission of the driving force of the motor to the wheel drive, with a different layout, the force can be redistributed to the machine for digging the ground or cutter.
  5. Wheelbase installation. Typically, rubber wheels with a deep tread with a diameter of 30 cm are used for movement. In some models, the wheels are replaced with all-metal rims with a corrugated structure, which loosen and do not roll away the soil. Another version of the device of the walk-behind tractor is a caterpillar track with the installation of control rollers to the hubs and the basis for the tracks from old tires or belts.
  6. The engine is forced air cooled.
  7. The fuel tank is mounted and the supply hose to the motor is pulled.
  8. The lugs for the walk-behind tractor are installed.
  9. All elements are carefully fixed, protective covers are installed.
  10. The device is ready for a test run.

Previously, the device must be checked in idling and only after a few test starts, first connect the light and then the full load. During the test operation, it is important to monitor all extraneous noise and vibration and immediately eliminate the cause of their occurrence.

Tips of professionals how to make a walk-behind tractor

The ideal motor choice for a home-made motor-cultivator would be the engine from the Izh motorcycle or the Druzhba or Ural chainsaws, they are quite powerful and sometimes even require a reduction in effort.

One of the most thoughtful designs belongs to Valentin Arkhipov, schemes and video layouts of his various units and adapters to the walk-behind tractor are available on the Internet. Based on his developments, you can develop your own project for assembling a walk-behind tractor with your own hands.

For connecting various additional equipment and trailers, a swivel joint is best suited, it will give maneuverability to the overall design.

In order to better understand the dimensions and avoid skidding when moving under load when performing a walk-behind tractor, the plow is made with a displaced axis relative to the movement of the apparatus.

For automatic adjustment of the plowing depths of the plow, it is convenient to use a special adjustable rail, limiting and leveling the movement of the tool during plowing.

By installing an additional sprocket and transmitting the movement of the drive to the brush, you can successfully clear the area from leaves and snow.

Assembling a walk-behind tractor is not an easy task and requires skills. But there is nothing insuperable in this. Using a database of technical literature, and most importantly, tips from forums of lovers of homemade equipment, almost anyone can assemble an aggregate for country needs according to their desires and needs.

Home-made walk-behind tractor: DIY manufacturing

Land plots in villages and large summer cottages require enormous labor costs during plowing, hilling and cultivation. The task can be greatly facilitated with the help of a tractor, but its cost is prohibitively high for many small farmers and gardeners. An excellent solution in this case is the assembly of a homemade walk-behind tractor from a chainsaw or motorcycle.

DIY assembly instructions

If you are seriously thinking about cultivating any garden crops in your country house or near a private house, you will need a motor cultivator. This universal miracle machine can fully automate most of the agricultural activities on your site, allowing you to plow the soil, plant and dig potatoes, remove snow, and sometimes carry out the transportation of some goods, including crops and fertilizers.

It is no secret that such an indispensable device can be bought at any agricultural hypermarket, but its cost can be prohibitively high. Therefore, more and more often summer residents are trying to make a walk-behind tractor with their own hands. But in fact it does not require special efforts and skills, while the amount of expenses is reduced to a minimum.

What is a walk-behind tractor

A walk-behind tractor, or a motor cultivator, is a self-propelled two-wheeled unit that is equipped with an internal combustion engine. The device freely moves forward, and the summer resident goes behind him, holding on to the handles with various nodes and controls. Many available models have multiple gears for moving forward and backward.. To exploitation of such an invention It was the most productive, it is equipped with additional tools, including a plow, which allows plowing and cultivating the land.

The average mass of the walk-behind tractor reaches 100 kg, and the engine power often exceeds 8 horsepower. Due to such features, such a tool can become indispensable for plowing the garden area.

You should pay attention to the fact that all walk-behind tractors are equipped with a special drive for attachments, which allows you to transfer part of the motor power to a suspended mowing machine. Basically, such a universal mechanism allows you to cope with various agricultural work, including:

  • plowing the land
  • cultivation
  • transportation of the crop (in this case, you need to get a small trailer),
  • mowing grass.

With the help of such miniature trucks, residents of our regions transport firewood, fertilizers and crops. In winter, it can be used as a tool for snow removal. Even the weakest model pulls a load weighing up to 400 kg seamlessly.

Cultivator benefits

Despite the many advantages, the excessive versatility of a walk-behind tractor is not necessary for every summer resident. Yes, and quite impressive weight sometimes complicates the operation of the device when performing daily tasks. Therefore, many owners of suburban areas prefer a simplified version in the form of a cultivator. Such a solution is characterized by affordable cost and low power consumption.

Most cultivators are much smaller motoblocks. Instead of the wheels, which are provided in the classic version, special milling cutters are installed here that are able to loosen and grind the earth when moving. They are the main working element of the cultivator. Unfortunately, it is impossible to use additional equipment operating from the power plant of this device. This is due to the lack of an appropriate drive.

Among the possible "snap" only "passive" tools, such as:

The weight of the cultivator does not exceed 50 kg, while on the market you can find many powerful models weighing up to 20 kg. Due to these characteristics, the car is very easy to hold with your hands, and fuel consumption remains at a minimum level. By the way, some products are equipped with an electric motor.

The cost of cultivators differs significantly from the cost of walk-behind tractors. A relatively low-power and inexpensive walk-behind tractor with a capacity of 6 horsepower will cost twice as much as a cultivator with similar performance indicators.

Application area

The advantage of the walk-behind tractor is not only in its low cost, but also in increased maneuverability, which allows you to work in areas where the tractor simply can’t pass in size. With it, you can process plots of only one square meter.

Depending on the installed additional equipment, the walk-behind tractor is used to carry out various types of work on a land plot. Light models are usually equipped with a weeding tool and a mill. Heavier specimens can already be used for plowing, hilling and mowing.

On a heavy walk-behind tractor installation of the following devices is allowed:

  • rake,
  • mower,
  • harrow,
  • plow,
  • trailer,
  • milling cutter
  • snow blower.

With this device, if you add a seat and a trailer to it, you can transport various loads weighing up to 300 kg over short distances. It is actively used for planting and harvesting potatoes and other crops. Motoblock acts as an indispensable assistant in cleaning large areas of snow, drilling and fertilizing the soil.

DIY assembly

Despite the fact that the cost of such an apparatus is many times less than a full-fledged tractor, not every summer resident or villager can afford to buy a factory-assembled walk-behind tractor. Prices for branded products range from 30 to 200 thousand rubles. The cheapest are Chinese-made units, the reliability of which is extremely doubtful.

DIY assembly of a do-it-yourself walk-behind tractor is a profitable option.The required costs, in the presence of most spare parts, which are usually always available on personal farms, will be minimal, and the quality is no worse than the factory one.

Necessary components

Before starting assembly work, you should determine what rated power will be on the homemade walk-behind tractor. The best option is to use the IZH Planet 5 motorcycle or a powerful chainsaw, for example, the Urals, as a donor of spare parts. But you can use any similar engines.

To build a homemade walk-behind tractor you will need:

  • blueprints,
  • welding machine,
  • set of tools,
  • steel pipes,
  • wheels from a car or sheet metal,
  • donor (motorcycle or chainsaw).

During the work, additional details will be required to connect the engine and frame. Attached equipment can be used factory or also made independently from improvised means.

Frame manufacturing

Since in each specific case the design of the unit may differ depending on the used parts and engine, before starting the assembly, you need to draw up a work plan and make the necessary design drawings, based on the operation manual of the factory motoblock.

General principles and the procedure for the manufacture of the supporting structure is as follows:

  1. Metal pipes are connected in the form of two spars with upward curved edges.
  2. A motorcycle wheel is welded to these edges. With its help, the motoblock will be controlled.
  3. Transverse steel amplifiers are welded to the side members. They will serve as a support for the transmission and engine.
  4. A metal plate is welded from the rear edge of the structure onto which the battery will be mounted.

In addition, you can use the finished motorcycle frame, slightly modifying it. You will need to remove the front fork and all parts that interfere with the installation of new equipment. A hitch mount should be welded behind it.

With this option, the wheels from the car are usually immediately installed, adding an axis from a solid round timber to the structure.

Creation of the power unit

Regardless of whether the motorcycle engine is installed on a walk-behind tractor, from a scooter or chainsaw, they must all have active air cooling. To facilitate starting, it is necessary to change the power supply system by replacing the fuel supply valve with a flap.

Muffler use motorcycle or make it yourself from a pipe with a diameter of 70 mm. To do this, cut a small part about 25 cm long from it, fill it with sawdust and shavings. The outlet must be narrowed in half.

The silencer should be located in such a way as to fully ensure exhaust gas to the side of the person who will control the walk-behind tractor. For the engine, a separate steel structure is assembled from pipes with a diameter of 42 mm. Outwardly, it should resemble a slide with brackets having holes for bolts, with which it is attached to the main frame.

Main nodes

In addition to the wheels, engine and frame, the multifunctional walk-behind tractor must be equipped with additional units, without which it is impossible to perform a number of basic tasks, and its use will be limited simple transportation of goods.

Stroke reducer - a gearbox element that makes it possible to operate the unit at the smallest speed. In factory models, the stroke reducer is installed on the gearbox, respectively, this must be done on a makeshift walk-behind tractor. When planting or picking potatoes, sowing or plowing the land, the power plant requires maximum power at the lowest speed. To achieve this effect without installing this node will fail.

A gearbox is a mechanism that provides the transmission of engine torque to individual nodes that drive the walk-behind tractor. Install it between the wheels of the unit and the engine.

When working with some additional equipment, the transmission of torque occurs directly to it. If a drill, milling cutter, snow blower or tracks are installed, the gearbox starts working directly with them. Without appropriate experience and knowledge, you should not try to assemble and install this unit yourself: it is better to purchase it in a store or remove it from old equipment.

Features of the choice of unit

If you want to choose a suitable model of a walk-behind tractor, pay attention to a number of important parameters. Among them:

  • cultivated area
  • type of tasks to be solved,
  • power equipment.

If the size of your site does not exceed 10 acres, then, naturally, it is better to opt for a device for cultivating the land. If you own a larger territory, it makes sense to think about buying a full-fledged walk-behind tractor.

As for the power indicators, they are selected taking into account the type of work that will be carried out on the site. For seasonal plowing of the soil in the autumn, it is enough to purchase an aggregate with an engine power of 5.5-6 horsepower. True, if we are talking about processing virgin soil and dry soils, then you will need to purchase a heavier model with a reinforced motor. Most likely, it will run on gasoline fuel standard A92 or A95. There are also diesel developments consuming from 2 to 2.5 liters of fuel mixture per hour of hard work.

If you want to purchase a miniature version of the tractor, give preference to products from trusted brands. It is no secret that small European-made equipment can be equipped with “native” power plants of more well-known manufacturers, so such an engine can serve the future owner for a very long time. If the equipment is provided with proper care and maintenance, it will work freely for about 15 years, and the same after major repairs in a good service center.

As for Chinese products, it cannot boast of good power indicators, reliability and durability. However, in this segment you can find a pretty good solution. Just carefully study the reputation of the company, get feedback from real buyers on forums and portals for farmers.

Home-made walk-behind tractor according to Arkhipov’s instructions

The design of such a motor block is made in the form of a self-propelled two-wheeled unit, which comes with an engine from a VP-150M scooter. This model of the motor has such a constructive character that under increased loads there is a forced cooling of the cylinder head with air.

If you follow the instructions of Arkhipov, then at the next stage you will have to make a U-shaped frame welded from the corpse, and then turn the wheel axle on a lathe. For the main and control rods, 3 hinges should be created that will act as connecting elements between the walk-behind tractor, steering wheel and plow.

In turn, the unit frame is equipped with a steel pipe with an axis using a welding machine. It will allow pull the cablesgoing to the gearbox. The tension itself is provided using a rocker arm. Gear shifting is carried out using a welded piece of steel pipe.

As for the analogues of such a development, there are really a lot of them, however, the original version has some indisputable advantages.

Advantages of Arkhipov walk-behind tractor:

  • The presence of a swivel. It is no secret that most of the processing devices and tractors are equipped with a rigid connection, which negatively affects the maneuvering of the unit, complicating the work with it. All elements of Arkhipov’s development are interconnected by means of hinges. Due to this parameter, it becomes possible to change the direction of movement during operation without removing the plow from the furrow.
  • The offset of the axis to the direction of travel. When cultivating the soil using a walk-behind tractor, many summer residents have such a problem as the gradual displacement of the unit to the side under the influence of resistance. To align the furrow, you have to put a lot of effort. To compensate for the drift, the master placed the axis of the plow at a slight angle in the direction of movement. Carrying out the work, the structure is slightly shifted to the left, and the necessary direction is regulated by means of traction hinges.
  • Plowing depth level. In most existing walk-behind tractor models, the immersion depth of the working element is determined by lowering or raising the plow. In the case of this variety, it is changed automatically. To adjust, the angle of the plow changes with respect to the furrow. In turn, the design is equipped with a field board, which acts as a lifting force for arbitrary plowing of the plow into the ground. If the problem manifests itself in the opposite way, and the ploughshare appears above the surface of the earth, then the angle of attack again plunges into the ground at a specific depth.

Walkthrough Assembly

You need to start assembly of the unit with the arrangement of the running shaft. Then it is equipped with a housing with bearings, an asterisk is welded and overrunning clutches are fixed, which act as a differential. Then the design is equipped with wheels and a frame with telescopic traction, a plow and a steering wheel.

The home-made version of the agricultural walk-behind tractor has special wheels at its disposal that are able to provide maximum traction.

To connect the unit frame with the suspension and the frame of the scooter, two arc-shaped metal pipes should be used. Between them establish a tank for storing the fuel mixture.

When arranging the power plant, a bracket is used, which is equipped with a steel axis 150 mm long. It is cantilevered to a U-shaped frame. The axis itself is equipped with a suspension motor, and the assembled product is connected to the arcs of the frame. Only then does the secondary shaft mount cable pulling and chain pulling.

Homemade design upgrade

Arkhipov's motoblock is very popular among a wide audience of summer residents and gardeners due to its versatility.Very often it is used as a plow or cultivator. To expand the functionality, it is enough to replace the removable parts for the plow with parts with removed dumps for the cultivator. As it moves through the garden, the appliance will dig furrows into the ground, laying potato tubers there. To plow planting material, it is enough to equip the unit with dumps and walk again between the planted rows.

In a similar way, the hilling of sprouted plants takes place. The agricultural walk-behind tractor is characterized by excellent productivity and ease of use, even for purposes such as harvesting. To change the width of the grip, it is enough to use different dumps. In addition, the unit is able to collect the missed potatoes and the remaining tops in the presence of a rake or harrow.

The universal design is indispensable not only for work in the field of agriculture. It can also be used for snow removal in the winter. Such a loyal assistant will be a good tool when cleaning paths and gardens from leaves or debris. It is enough to equip it with a roller with a round brush and an additional sprocket, which will allow you to clear the sidewalks.

Every self-respecting summer resident sooner or later comes to the issue of buying or manufacturing a cultivator. Similar unit - Really valuable find for people engaged in organic farming. With its help it is possible to process both small gardens, and large territories from 30 hundred parts.

Despite the compact size, such a miniature "truck" not inferior in productivity to some tractors. A powerful engine is able to process the heaviest soil, and ease of use allows you to operate it even in the absence of specific experience. In addition, to make such a device is much easier than it might seem at first glance. It is enough to pay attention to the existing instructions and take advantage of the recommendations of professionals.

How to assemble a makeshift walk-behind tractor from a chainsaw Friendship

An avid gardener and gardener have to dig up large tracts, which is very tiring, especially when a person is already retired. In addition, this monotonous work is quite boring for most people. Digging, loosening and weeding will take much less time, if you use not the simplest tools, but use a home-made walk-behind tractor, with which it will be more fun!

Cultivator application

Since it takes a lot of effort to process even a small piece of land, summer residents are thinking about making a chopper. These workers come to the idea of ​​making a home-made walk-behind tractor with their own hands due to the fact that factory-made walk-behind cultivators are expensive.

Self-made motoblocks are used to carry out the following procedures:

  • plowing,
  • hilling,
  • mowing
  • fertilizer application.

Do-it-yourself motor-plow will also help with snow removal and weeding weeds, and if you add a trailer, you can use it to transport goods weighing up to 200 kg. The complete set of a light motoblock usually includes only a mill and a propolnik. On a mid-weight product, you can find a milling cutter, a plow, mowers and a hiller. Heavy products are reliable, have high traffic and fixed wheels. With such a device of the walk-behind tractor, the following equipment can be used:

  • milling cutter
  • plow,
  • harrow,
  • rake,
  • mower,
  • semitrailer,
  • snow blower.

The benefits of homemade designs

The main plus is saving money. To assemble the walk-behind tractor, the following materials and tools are enough:

  • Motorcycle engine or chainsaw motor, welding machine.
  • Steel pipes.
  • Wheels from a passenger car or sheet metal for making lugs.
  • Details for connecting the motor to the frame.

For example, you can make a motor-block from a Druzhba chainsaw with your own hands, if you have a drawing and the necessary equipment.At the same time, the motobord trimmer will fulfill all the functions of the factory models. If you choose a powerful engine for a milling cutter, the product will not yield even to modern factory motoblocks.

Attachments can also be made independently: a one-wheeled unit will not need a differential.

Power part

In the manufacture of the power unit, the following conditions are required:

  • The engine must have air cooling, which is necessary at a low speed. Often installed gasoline power units from scooters or scooters with a capacity of about 13 liters. from.
  • The silencer is made independently from a metal pipe Ø70 mm. To do this, about 25 cm of the pipe is cut and filled with chips or sawdust. The configuration of the exhaust pipe must allow the exhaust gas to the side, otherwise when moving the exhaust interferes with work. The diameter of the outlet should be approximately 16 mm.
  • The frame for the motor is made of steel pipe Ø42 mm. The design is made in the form of a sled. At the edges of the structure and in the center of it are attached brackets with holes for bolts.
  • After that, the frame is welded to the rail cross member. It is located so that the central bracket is directed down.

The engine is mounted on the finished frame.

Features of handling equipment

The most widespread Arkhipov walk-behind tractor with a swivel between the attachments and the tractor. This feature allows you to spend less effort during operation, and the created furrow during turns remains uniform. The depth of plowing provided by the unit is the same throughout the plot, and additional effort is not required to complete the operation.

Motoblock Arkhipova

A self-propelled machine on two wheels with an engine from a VP-150 M scooter. This power unit is selected for structural reasons: for forced cooling of the cylinder head by air.

A steel pipe is attached to the unit's frame by welding, which ends with the axis needed to tension the cables going to the gearbox of the motor. The tension is carried out by a swinging beam, the gearshift knob of which is a welded section of a steel pipe. The chain pitch is 12.7 mm and 15.9 mm. The number of teeth of the sprockets: the running axis - 40, the secondary shaft - 20 and 60, the output shaft - 11.

There are enough analogs of the model, but the original design of the Kaluga master has undeniable advantages:

  • Swivel joint. The processing tools and tractors of most of these models have a rigid connection that complicates the maneuvering of the walk-behind tractor and impedes its operation. The parts are connected by hinges, so there is the possibility of the direction of movement without removing the plow from the furrow.
  • Plowing depth. If in other models the depth is supported by lowering or raising the plow, in the case of work with the Arkhipov walk-behind tractor, this is done automatically. Regulation is made by changing the angle of the plow to the furrow. The design provides for the presence of a field board acting as lifting force when burying the plow. When the ploughshare appears above the ground, the angle of its application of forces instantly increases, under the influence of which it again burrows to the required depth.
  • Axis offset in the direction of travel. The axis of the plow is placed at a small angle in the direction of movement. During plowing, the construction rotates slightly to the left. The necessary position is regulated by three draft hinges.

Optional equipment

Attached equipment is often:

These tools are fixed on a special bracket mounted behind the engine.

The potato is dug up with the help of a special digger, pulling the tubers out of the ground without damage. For harvesting mowed grass or tops, a rake canopy is used.

With additional equipment, the walk-behind tractor not only processes the soil, but can also be used to clean the area.If you fix a bulldozer knife on the block, it will effectively remove snow, with a roller and brush, it will sweep garden paths.

Attachments

The motoblock is a multifunctional unit and, in addition to processing the land allotment, it is actively used for cleaning territories, transporting goods and mowing grass. Using the bracket installed on the back of the frame, it is attached to it: a plow, harrow, rake, mill, digger, bulldozer knife, rollers, brushes and other devices.

Many models, including homemade ones, are equipped only with a steering wheel. The person in this case goes behind the walk-behind tractor in the process of performing work. However, if necessary, you can make an adapter that allows you to control the unit while sitting.

For the adapter you will need:

  • steel sheet,
  • seat,
  • a pair of wheels
  • trumpet,
  • hitch
  • tools and welding machine.

At the end of a rectangular pipe, 1.7 m long and 6 cm wide, 4 cm high, you need to weld a half-meter pipe on which there will be wheel racks. The height of these racks from the mount to the center of the axis is 35 cm. The seat can be of any design, but should not exceed the size of 45 × 45 cm.

After assembling and installing the wheels, the attachment control is attached to the frame and the structure is connected to the walk-behind tractor with a hitch.

4x4 mini tractor Kalujanin Arkhipova

We organize the topic ??
So to say hello from childhood, or youth.
MT Kalujanin Arkhipova, there were publications in the MK and the program “You can do this”.

I didn’t find the video transmission, there is a video copy on YouTube, and what information is in the tyrotnet.

KALUZHANIN: MICROTRACTOR-UNIVERSAL
Regular readers of our magazine are already familiar with the Kaluga amateur designer V. N. Arkhipov, the author of a lightweight and productive walk-behind tractor (see MK, No. 6, 1982). However, Valentin Nikolaevich believes that working with him is not so simple as it might seem: walking on plowed land, controlling a walk-behind tractor and simultaneously mounted implements, is quite tiring and not everyone can do it. That is why Arkhipov took up the construction of a four-wheeled mini-tractor in order to “saddle” it: to carry out various agricultural work while on it. The attempt was a success, a kind of wheelchair appeared - the Kalujanin-14 mini-tractor. Not so long ago, the author represented him in the popular television program "You Can Do It" and received the approval of a competent jury. Today, at the request of viewers and our readers, the magazine publishes drawings according to which it is possible to build the same “iron horse” - an assistant in your household and garden plots.

Arkhipov also made a whole arsenal of mounted and trailed implements: now the Kalujanin can plow, harrow, spud, cultivate, plow, and carry a trailer. In winter, he cleans the yard and the road in front of the house from snow. It also serves as a kind of “energy center” - it drives a pump, circular saw, sharpener, winch, and even a generator.

Another advantage of the tractor is that the designer tried to lay in it a minimum of labor-intensive operations in the manufacture of parts that are simple and technologically advanced. A whole series of constructive solutions used by V. Arkhipov is original: a four-wheel drive device, the combination of steering and braking mechanisms, the use of semi-axles instead of axles, the agricultural equipment hitch assembly is simple and convenient to operate.

I’ll start with a list of the basic blanks that you need to have before you get started. You will need a metal sheet 4X200X600 mm and two sheets 1X300X800 mm, strips 3X25X1800 mm, pipes Ø48, 38, 25.4, 26.8, 21 mm (lengths of 6000, 1200, 1000, 1500, 4000 mm, respectively), rods of Ø50 and 100 mm by 800 mm long.

Of the finished parts and assemblies (purchased, from discarded agricultural machinery), sprockets with 13, 20, 54 teeth and 19.05 mm pitch and corresponding chains, a pair of pulleys from reel mowers for brake clutches, wheels or metal disks for them Ø600 mm are required. From the SZA stroller, use the main gear with a differential, universal joints, a muffler. The engine is from the Tula-200 scooter. I must say that any of these details can be replaced without much damage by others - appropriate. That includes the engine, but subject to one condition - a power of at least 10 liters.from. and the presence of forced airflow. Suitable, for example, an engine from SZA.

To ensure the simplicity and reliability of the ignition system, it is better to abandon the battery and generator and put magneto from the starting engine of the Belarus tractor.

The Kaluzhanin frame is welded from pipes of the diameters listed above. In its front part there is a footrest serving as a support for the driver’s legs, a transverse corner for fastening the friction clutch handles and metal strips for installing the seat from the back are welded on top, and wheel bearing housings from the bottom. In addition, on the lower power tubes, pillows of bearing housings for the axle shafts of the differential and the intermediate shaft, brackets of the axis of the rocker arm of the mounted tools were delivered. On the rear pipe there are kerchiefs for fastening the main gear and a vertical bracket on which the engine is suspended on an axle-bolt: in front it rests on a transverse corner. Superimposing on the last adjusting washers, you can slightly change the position of the engine (its inclination), which regulates the chain tension from the output shaft of the engine to the eye gear. Behind the seatback is a gas tank (from the Electron scooter), fuel is fed by gravity.

All four wheels of the mini-tractor are driving: the rotation on them is transmitted by chains through the main gear and the intermediate gear. The drive axles are equipped with cardan joints, friction discs and sprockets (Z = 13). The outer ends of the axle shafts are embedded in bearing housings in bearings on the frame. On the shafts of the intermediate gears (there are two of them - one on each side of the mini-tractor) there is a large, 54 tooth receiving sprocket and two 13 teeth transmitting rotation to the front and rear wheels. The shafts are inserted at one end into the bearings of the support, at the other into the bearings of the consoles, the latter being welded to the front tube of the frame. The axles of the wheels have one driven sprocket (Z = 20). All connections are keyed.

Thanks to the main gear with a differential, it is possible to individually lock either the right or left wheels and, as a result, turn in one direction or another. Locking is carried out by a handle with a belt lining using friction discs: pressing against the disc, it slows down the rotation of the axle shaft. The handle is bent out of the pipe: it can be rotated on an axis installed in the corner consoles of the frame. At its end, a support plate is welded under the plate - a segment of the drive belt, fixed through it and the pipe with two bolts. Many people think that if you put a clamping belt completely covering the pulley on the friction clutch, then braking will be more effective. However, as practice has shown, touching the disk in one place is quite enough. The tape is often "grabbed."

The wheels are placed on the axles, supported by bearings. On the one side of these bodies are the wheels themselves, on the other - driven sprockets (Z = 20). Due to the fact that the drives are spaced apart on the drives of the intermediate gearbox, it is necessary to install the followers in different planes. This made it possible to manufacture bearing housings (respectively, half shafts) of different lengths: front - 110 mm, and rear - 85 mm. There is no additional chain tension here: sufficient coverage of the sprockets helps them. If the chains stretch over time, you only need to shorten them - remove a couple of links. Thus, in the entire transmission, only the chain coming from the engine output shaft is regulated.

The wheels are made of metal discs Ø600 mm and a thickness of 8 mm. Rings (through 70 mm) from strips of 6X30X200 mm are welded onto them around the circumference: they facilitate turning and at the same time help to ensure sufficient traction - the wheels do not skid even on ice when snow is being cleared, they do not “grease” even when working on wet soil.

Agricultural equipment is hung on the beam, passing under the frame of a mini tractor. Cultivators, harrows, rakes are usually positioned so that they fall in the middle of the rut.But with a plow more difficult. The point here is that the resistance of the plow when plowing turns the car around - after all, its wheels in this case go on the furrow or virgin soil on one side, and on the already plowed land on the other. Therefore, depending on the working conditions (soil density, plowing depth, etc.), it is necessary to shift the plow. And how much - this is determined already, as they say, in practice. In order to be able to rearrange the plow without any particular difficulties, I put the beam on the sleeve, which “walks” left and right across the frame on the axis. The attachment point of the plow should be at the level of the axles of the wheels. Otherwise, a certain unfolding moment arises in the vertical plane and the car will “stand on its hind legs” or, conversely, overload the front end. Another. Obviously, the furrow during plowing should be equally deep along its entire length. But how hard it is to achieve, moving along all the irregularities of the field!

It is easier to ensure uniform plowing at the Kalujanin than on tractors with implements mounted directly on the stern, when any tilt of the machine affects the quality of the tillage. At my car, the suspension point of the plow rocker arm is located on the central axis of the base, and it is not fixed in the vertical plane and can "swing". Therefore, no trim affects the depth of the furrow - the depth of the plow will be almost constant. I also advise you to put a seat in the center of the tractor - the driver will be much more comfortable: less pitching. Indeed, the "excitement" when moving along bumps and potholes is quite noticeable. It is better to move gas control, reverse, gearbox, clutches somewhat forward, but so that everything is at hand, as expected. In this case, when driving a “plowman” from one plot to another, it will be possible to “lead” him, following him.

V. ARKHIPOV, Kaluga

Those who are able to do something themselves do not need comments, in principle, everything can be found through a search engine.

Well, two video copies, though with a CPA engine.

Homemade trailer

The trailer can be made in several ways and using various materials. As a rule, home-made structures are made of metal frame and wood.

Procedure:

  1. To make a carrier consisting of a drawbar and a rotary body. Connect to the frame so that the hinge is inside the tubular body.
  2. To make a frame according to previously drawn drawings from a pipe with a diameter of 60 mm. Sheathe wood or metal sheet.
  3. Using a solid metal axle, install the car wheels on the structure.
  4. Assemble a driver's seat from wood.

The rear side of the trailer is foldable to facilitate loading and unloading. Metal amplifiers are welded on each side. The trailer is painted and connected to a walk-behind tractor.

How to make a homemade walk-behind tractor with your own hands

Cultivating the land during the cultivation of a personal plot always requires certain physical effort and time. Therefore, some owners of land over time acquire motor blocks, greatly facilitating this work. Their diversity is widely represented on the market today, but if you wish, you can do it yourself, significantly saving money at the same time, and collecting equipment for specific operating conditions. Many craftsmen prefer to assemble a walk-behind tractor with their own hands.

ICE based technology

Homemade products with installed internal combustion engines have more power and functionality compared to electric counterparts. This allows you to significantly expand the scope of their use. Attachments in the form of a plow, plane cutter, cultivator, rake, easily mounted on the frame bracket. Also, the unit can be easily transformed into an ice rink or a home mini-tractor.

Asking the question "how to make a home-made walk-behind tractor", first of all you need to understand his device. To assemble a do-it-yourself motor-cultivator with your own hands, you need, first of all, an engine, transmission and a reduction gear.

For assembly work, you will need a standard set of tools: a set of wrenches, a drill, a grinder, a welding machine, and when assembling more complex and lifting machines, also turning and milling of some nodes.

Chainsaw cultivator

Perhaps the most optimal option in the manufacture of a home-made motor-cultivator is to use a chainsaw engine to create it. The advantages here are the performance and power of the unit, low fuel consumption, low weight and compactness. And with the components during its assembly there will be no special difficulties. Everything you need can be found at the car market or flea markets.

General scheme of motoblock:

  • the motoblock frame is made in the form of a rhombus from a metal corner with a size of 3200x3200x3200 mm,
  • the engine is mounted on the crossbars from above, the gas tank, as a rule, is mounted a little lower,
  • the intermediate shaft bearings are attached to the front struts,
  • bearings of a running shaft are established on longitudinal edges

With this arrangement, the center of gravity of the unit has a rear location (above the support wheel), therefore, for its displacement, you can install an additional weighting in front.

To adjust the speed, a native gearbox is used, motorcycle sprockets (main and intermediate,) are also used, the number of teeth of which is selected taking into account the required power output. The working tools of the unit are made in the form of wheels with knives and can perform the function of a trimmer, milling cutter or motor chopper.

As an alternative, you can use the engine from the brushcutter, which is similar in its characteristics to the drive of a chainsaw.

Motorcycle motoblock

Often, old motor vehicles can rust in garages and barns for years, but they can easily find a second life. Motorcycle engines are great for making a do-it-yourself do-it-yourself motor-cultivator, but two-stroke engines from older models, as well as from scooters, are most often used. But recently, motors from scooters or mopeds have also begun to be actively used, giving alterations a second life to broken equipment.

Transmission can be of several types:

  • toothed - the most common and easily mounted,
  • combined (gear-worm gear),
  • chain-belt, gear
  • hydraulic gearbox - gaining popularity, but the most expensive compared to the mechanical type of transmission.

Everyone chooses which system to use, depending on the details available and the functionality of the equipment to be laid. But from practice it can be noted that homemade trimmers in their characteristics can compete with factory models.

Possible schemes

A frame of the required size is welded from the corner, to which an engine with a fuel supply system and a gas tank is attached. The transmission of torque from the reduction gear to the wheels is via a chain. In this case, you can use the bridge from the donor motor technology mounted on the wheel axle. All controls are transferred to the steering wheel of the unit.

When designing heavier equipment, a standard ZID-5 engine or its other modifications, which were previously widely used on various units, are used. In conjunction with it, a gearbox from Zaporozhets and a lightweight drive axle are installed.

Electric units

When processing small plots of land electric cultivator can be a good help. The most popular is the industrial model "Mole". As a rule, an electric cultivator has less power, and its use is limited by the power cord. But still this technique is very popular among summer residents.At the same time, many craftsmen prefer to make a homemade electric cultivator with their own hands.

Principle of operation

The power unit of the electric cultivator is an electric motor that transmits torque to a wheel type milling cutter or other element of land processing through a gearbox. The controls for the equipment are located on the steering wheel. Most often, unicycle electric cultivators

The necessary depth of loosening of the soil is achieved by pressing the handlebars and adjusting the height of the coulter. As a rule, it is about 25 centimeters, which is enough for cultivating the soil.

The second life of the meat grinder

As the basis for a home-made electric cultivator, you can use any electric motor designed for 220 V, but most often craftsmen use a power block and a reducer from an electric meat grinder.

The only thing to do is knock down the working nozzle and install the shaft in its place (most often, boring scrap is taken for these purposes). Grouser wheels with knives are attached to the shaft, which easily break and loosen the ground.

But other types of electrical engineering can also be used as power blocks, so if you want to experiment with the assembly of your own electric cultivator, drawings of such equipment can be easily found on the Internet.
