We make a motor-block with our own hands on the example of a design from Valentin Arkhipov

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.

We build a walk-behind tractor according to the instructions from Arkhipov

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 made 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 welded length of a steel pipe acts as a gearshift knob.

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. The 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 ground to a predetermined depth.

Step-by-step device assembly technology

The assembly of the structure begins with the arrangement of the running shaft. To do 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.

And yet, you can build an adapter for a walk-behind tractor, read about it: tech / adapter-dlya-motobloka-svoimi-rukami.html

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

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: 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.
