Do-it-yourself walk-behind tractor: how to make it, homemade with a box from a Lada, assembled from a gearbox and rear axle of a VAZ (Lada), ZAZ, drawings, dimensions, how to connect

Many people are interested in whether it is possible to make a walk-behind tractor with their own hands. A heavy walk-behind tractor or compact walk-behind tractors are indispensable assistants in agriculture, but not all farmers and summer residents have the opportunity to purchase such equipment. Therefore, if you have certain skills, knowledge and skills, you can assemble a walk-behind tractor with your own hands. In order for a self-assembled motor cultivator to serve for a long time, a project diagram is created. It is necessary to correctly measure the parts, purchase materials and tools, and complete technical drawings and dimensions of components. You can use one of the instructions from folk craftsmen who write on special forums on how to make a walk-behind tractor with your own hands.

Any recommendations on the Internet on how to make a walk-behind tractor yourself should be checked against reviews. It’s good if the users of such homemade walk-behind tractors are friends or acquaintances. Then their reviews can be trusted; in other cases, all advice on assembling and using homemade devices should be checked.

How to assemble a walk-behind tractor yourself

Let's look at how to assemble a walk-behind tractor with your own hands. Parts that can be used for DIY are taken from old motorcycles and scrap metal. As an engine, which is often installed on homemade motor cultivators, you can use a motor from Druzhba - a chainsaw.

This engine has sufficient power to allow the use of various attachments. This significantly expands the functional use of motor cultivators. Many people install the engine from the Ant scooter on their walk-behind tractor, which has excellent characteristics and parameters for working in their summer cottage.

To create a walk-behind tractor at home, you will need the following spare parts and materials:

Steel corners measuring 36x36 mm or pipes 60x50x2 mm. From these parts you can assemble a frame for a walk-behind tractor.
Engine fully assembled.
Fuel tank.
Exhaust system.
Air filter.
Kickstarter.
The steering wheel on which the clutch and gas handles should stand.

The following tools will help you make a walk-behind tractor with your own hands:

Welding machine.
Drill.
Vise.
A set of horns and spanners.
A grinding machine on which a special disk must be installed for cutting metal.

Manufacturing the device frame

Before you make a homemade walk-behind tractor, you should prepare all the necessary parts in advance and draw up a drawing. The frame is a supporting structure, which is necessary to secure the remaining parts of the walk-behind tractor. To create it you need to do the following:

It is necessary to bend and connect a metal pipe into a structure in the form of two spars, the edges of which are bent upward.
After this, a steering wheel from an Izh motorcycle is welded to the rear side of the spar.
To make the trailer more reliable, cross members are welded to the side members. They increase the rigidity of the structure. The front cross member will serve as a support for the transmission chain tensioner.
A metal plate needs to be welded near the bends of the rear edge of the side members. It will serve as a support for the battery.

Scheme for creating a walk-behind tractor

A homemade walk-behind tractor from a ZAZ gearbox consists of 2 wheels, is self-propelled, and is assembled with an engine that has forced cooling of the cylinder head. It is carried out using air. The motor must be selected so that it can operate at different speeds, including low speeds, and be capable of performing large volumes of work. You can install a motor from a scooter and remove other elements from it:

control cables;
engine mounts;
handles;
chains;
arc, frame.

The brakes on the walk-behind tractor are used both factory-made and our own. Homemade brakes will allow you to take into account the necessary parameters and loads.

Having everything you need at hand, you can make a homemade mini-cultivator at home quickly and without any problems. A walk-behind tractor based on the ZAZ gearbox is created as follows:

A U-shaped frame is made from steel pipes.
On a lathe, you need to turn a wheel axle from a steel pipe with a thick wall with a diameter of 80-100 mm. Weld homemade wheel hubs to the ends of the pipe, which can serve as ball bearing housings with a place for mounting the wheel.
Weld brackets to the pipe, attach the Zaporozhets gearbox and the holder for mounting the motor to them. The engine can be installed directly on the ZAZ gearbox.
Make 3 homemade hinges that are installed on the front and control rods. This approach to assembly was used by designer Arkhipov when he made his walk-behind tractor. Hinges were used to connect the cultivator, steering wheel and plow.
Weld a steel pipe onto the frame of the car, on which there should be an axle. It is needed to carry out the tension that is transmitted to the gearbox. In order for such tension to be constantly present, it is necessary to make a rocker arm.
Weld the gear shift knob. A small piece of steel pipe is suitable for these purposes.
The chassis can have chain pitches of 12.7 and 15.9 mm. The sprockets on the chain have the following characteristics: output shaft - 11 mm, secondary shaft - 60 and 20 mm, running axle - 20 mm.

The main stages of manufacturing a walk-behind tractor:

The frame is welded, on which the engine must then be installed, 2 pipes in the form of an arc.
The fuel tank is attached between them.
We assemble the motor using a bracket, which is also welded to the frame.
You need to attach a motor with suspension to the axle, and then all the parts are connected to the frame arches.
The secondary shaft is mounted.
Control cables are being pulled.
The chains are stretched.

Tracked module "YUKON" | Topic author: Yury

With this topic I begin the construction of a motorized towing vehicle. As soon as the production of components begins, I will post photos and descriptions; therefore, I will not think ahead about the performance characteristics as the play progresses.

Yury (Yoshihiro) If you install a planetary gearbox on both sides of the shaft on a gearbox that has been converted in this way, the result will not be a frail axle for a caterpillar vehicle, but a ridiculous weight.

Yury (Yoshihiro) For this device I want to buy a LIFAN 15 hp with an automatic clutch and electric starter, the price in Irbit is 11,900 rubles. There is a variable valve available, but for now I want to reset it from the engine with an automatic transmission, no problem, and the price difference is 600 rubles

Yury (Yoshihiro) Today I spent a little time centering the shaft, turning out the flanges and bearing hubs.

Yury (Yoshihiro) Shaft diameter is 28mm, seat bearings are 30mm, and the bearing hub is part of a classic bridge. All that remains is to cut the keyways and make the sprocket mounting bushings.

Vladimir (Teri) Yuri, things are going quietly, everything is beautiful and correct.

Yury (Yoshihiro) Hi Vladimir, today I want to start bending the plastic pipe for the stars that I used to make the teeth for the Yukon. The thickness of the pipe is 4.5 cm thick, but there are water pipes 2.5 cm with those it will be simpler. How are you?

Yury (Yoshihiro) I want to buy this kind of engine, but I don’t even know when I’ll get to Irbit

Sergey (Liberato) Yuri, greetings! The topic is interesting, I also plan to build a light mini caterpillar vehicle, what do you think, if we bring to life a military mini all-terrain vehicle of the “elk” type, there is a 22 hp Lifan, enough power, do you think?

Yury (Yoshihiro) Well, if only as two twin motorized towing vehicles, and if anything more, the engine is rather weak. If you want to make a two-link, then take the box from the LUAZ and its rear axle and assemble two motorized towing vehicles. The first with an engine, the second through an articulation only with a bridge, I think the idea can live!

Yury (Yoshihiro) Today I tried to cook a stew from a plastic gas pipe, heated the oil to 160, it boiled terribly, but the pipe did not give in to me

Yury (Yoshihiro) I slightly altered the bridge, since the shaft offset is large and can bend, so I made stockings.

Yury (Yoshihiro) Now I’m thinking about what to make stars out of? I wanted to use a nylon pipe, but I couldn’t straighten it out; if you do it like on KOIRA, then for the caterpillar it is advisable to need a thin-walled nylon pipe of 2 cm. It’s not there, in general, it’s an ambush. :(((((

Transmission and clutch

A self-made motor cultivator based on a VAZ gearbox or based on a manual transmission must have an excellent transmission. It is needed in order to transmit rotating torque from the motor to the wheels, change the speed and direction of the machine. This part of the walk-behind tractor consists of units that are connected in series to each other:

gearbox;
differential;
clutch;
Transmission.

Gearboxes and gearboxes are divided into several types:

belt;
chain;
gear;
combined.

The most optimal solution is to install a gear transmission on the walk-behind tractor, which has several forward and reverse speeds.

In motor cultivators, you can use transmissions that consist of 2 gearboxes - a gear (installed on top) and a worm (mounted on the bottom). This design is suitable for light and medium-sized machines, but for heavy walk-behind tractors it is necessary to install more modernized versions.

The gear-worm transmission can be equipped with a centrifugal automatic clutch. The belt drive on gearboxes of this type can also act as a clutch, which performs its functions through a tension roller and a control mechanism (rod and levers).

An important part of the transmission and clutch is the release bearing; the speed of torque transmission depends on the release bearing.

Motoblock based on VAZ-2108 gearbox

If during disassembly you were lucky enough to purchase a five-speed gearbox from a VAZ-2108/2109/2113/2114/2115 car, you can assemble a walk-behind tractor based on it using the following tips:

The U-shaped frame is best made from angle steel. A transverse rack for mounting the engine and gearbox is also welded from it.
To attach the gearbox to the frame, use the standard mounting holes and bolts. To maintain alignment, use steel plates, from which holders of any shape can be machined and welded to the frame.
To connect the wheels to the gearbox, you can use steel “cups” that will be attached to the hubs on the brake disc housing. The brake system can be taken from the Gazelle.
The chassis is attached to the frame using steel plates that can be screwed directly to the hubs.
The engine is installed above the gearbox and bolted to a pre-prepared transverse rack.
The clutch belt system is controlled by a self-retaining lever, which is located on the handle of the walk-behind tractor and is connected to the movable clutch mechanism by a cable and spring.
The gearshift lever can be taken from a VAZ, or you can make it yourself from a round tube of suitable diameter.

How to connect an engine from a walk-behind tractor to a VAZ gearbox

In order to connect the engine from a walk-behind tractor with a VAZ-2108 gearbox, it is necessary to select suitable pulleys and belts for transmitting torque. A smaller diameter pulley is connected to the engine crankshaft, and a larger pulley is attached to the frame using a pipe at such a distance as to ensure sufficient belt tension. The belt (or pair of belts) is tensioned between the pulleys through the clutch tension roller coming from the gearbox.

The shank is from the classics on the gearbox and the oil seal I put in the same place has a smaller diameter from the shank box, I also want to do this, but I can’t figure out the seal

This is a photo of shortening the axle on an old tractor, it has already been sold. Then, by the way, I didn’t even think about it, that the oil seal was larger, for some reason the oil didn’t leak out when driving, maybe because the revolutions were very low, it didn’t splash it so much.

then I’ll try to put it in the same way, maybe it won’t work, I think I’ll put a tube on the flange under the diameter of the seal and put it on the sealant, it will hold no

Try it, I don’t see anything wrong with it. Only if it doesn’t allow debris and dust to get in there. If it doesn’t work out, then think about the oil seal. What can’t you do with the original shank. Now I’m making a loader and will install a short front Nivov cardan from bridge to bridge or do you not have all-wheel drive?

All-wheel drive will be so easier to connect the driveshaft from the box with a shank because of this, that’s the only way I want to do it

hi on the box, what diameter should the pulley be installed? Is 15cm something like this will do?

The tractor doesn’t need speed, the more, the more powerful it will be. Basically, they install a 2-strand Neva walk-behind tractor, approximately 30 cm in diameter.

thanks, clear, how to put it on the splines

On the first tractor, I found a pulley with a hole that fit tightly on these splines (but the pulley itself was without splines), but there was a counter bolt on the pulley. I don’t remember exactly, but I think I used a grinder to grind it on the shaft for this bolt and there are no other fasteners anymore. it was. And so you take the core (one or both sides at once) from the clutch and weld it to the pulley and that’s it.

thanks, I'm shopping, I'm running around looking for a pulley from a walk-behind tractor

The day before yesterday I looked in two stores, although there are no spare parts on the shelves, and if you ask about spare parts, they say there are spare parts, so I was looking for a pulley from a Neva walk-behind tractor, but it wasn’t there, we’ll continue the search. Maybe I’ll find something for the compressor .

We have a lot of spare parts for the walk-behind tractor here, I'll spend the weekend

HI, what do you think, a Chinese engine from a 6 5 hp walk-behind tractor will be suitable, it will handle no, such an engine is the cheapest we have 5 hp

My first tractor rode on a 4-horsepower engine, but I didn’t try to clear snow or plow with it. And there are a lot of people on YouTube with a 6.5-horsepower engine. Take the same Soviet walk-behind tractor from which engines are installed on tractors, there too 6-6.5 horses and nothing to plow and clear snow. Of course, it is advisable to use more power.

Well, yes, more powerful prices bite, we'll see

We have a point on the market (I don’t take the stores into account, they’re a bit expensive), that’s how many horses there are, that’s how much it costs. I want to get a 7 or 9 horsepower engine. And then we’ll see, maybe we’ll ride on our own.

I went through all this once. If you sculpt something from something just to make it cheaper and drive somehow, then repairs and alterations will take more time and money. I know firsthand. After several failures, the craftsmen simply abandoned their project or, having gained some experience, radically limited their homemade product. I advise everyone who loves and knows how to tinker with hardware to study the transaction itself, fortunately there are a ton of videos on YouTube.

What are the advantages of working with a 4-wheel walk-behind tractor?

Each model of such equipment is a kind of mini-tractor made on the basis of a walk-behind tractor. Working with it has several advantages. Among them stands out:

Comfortable control of the unit using an ordinary steering wheel;
The presence of a driver's seat, which allows even elderly people to cultivate the soil;
Each four-wheel walk-behind tractor is equipped with a hydraulic drive for attachments - raising and lowering the equipment is carried out by manipulating the lever;
Tilling the soil with such units is considered to be of higher quality, and the work takes a little less time;
The power of the models allows you to safely transport trailers with cargo with a total weight of up to 800 kg.

A walk-behind tractor with 4 wheels is the best option for owners of large plots. You can use it to get directly to the landing site, work all day without long breaks, and go home.

Modernization of a homemade design

The Arkhipov walk-behind tractor is extremely 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 moldboards for the cultivator. As it moves around the garden, the device will deepen furrows into the ground, placing potato tubers there. To plow the planting material, it is enough to equip the unit with dumps and walk again between the planted rows.

Hilling up of sprouted plants occurs in a similar way. The agricultural walk-behind tractor is characterized by excellent productivity and ease of use, even for purposes such as harvesting. To change the working width, it is enough to use different blades. In addition, the unit is capable of collecting missed potatoes and remaining tops in the presence of a rake or harrow.

The universal design is indispensable not only for work in the agricultural sector. It can also be used for snow removal in winter. Such a faithful assistant will be a good tool when clearing paths and garden areas from leaves or debris. It is enough to equip it with a roller with a round brush and an additional star, which will allow you to clear sidewalks.

Every self-respecting summer resident sooner or later comes to the question of buying or manufacturing a motor cultivator. Such a unit is a truly valuable find for people involved in organic farming. With its help, you can cultivate both small gardens and large areas of 30 acres.

Despite its compact dimensions, such a miniature “truck” is not inferior in productivity to some tractors. The powerful engine is capable of processing the heaviest soil, and ease of use allows you to operate it even in the absence of specific experience. In addition, making such a device is much simpler than it might seem at first glance. It is enough to pay attention to the existing instructions and use the recommendations of professionals.
