A master class on how to shorten the rear axle of a VAZ can be useful for making (and inventing) all kinds of homemade products with a changed track width and wheelbase: mini-tractors, ATVs, go-kart cars. The craftsmen involved in such alterations, of course, already know everything. But if a person who is not very experienced in design undertakes to make something similar, then the information can be very useful. We will consider how to shorten the rear axle of a VAZ using the example of an ATV design, which usually uses many parts from the VAZ classic, including the rear axle. But for these purposes it is pre-cut, thereby reducing the width of the wheelbase.

How to make a tractor from a Lada with your own hands

Many farmers are interested in how to make a tractor from a Zhiguli with their own hands. Farms or owners of large plots of land need the help of agricultural machinery. However, not everyone has a large amount of money, because a factory tractor costs a lot of money.

In many farms you can find old Zhiguli cars that have already served their purpose, but have a chance for a second life. Based on this machine, you can create a homemade Zhiguli tractor, which will have the same characteristics as purchased copies. And the engine can be taken from a VAZ 2109 or VAZ 2106 model.

Mini tractor from VAZ: advantages of self-assembly

Owners of plots of more than 10 acres often need the help of an agricultural machine. However, not every farmer can afford to buy factory equipment. In this case, you can make a mini tractor with your own hands with a VAZ engine. This will take time and effort, but very soon they will be compensated by the appearance of a reliable assistant on the farm, which can be used not only in the garden, but also in the local area.

Making a mini tractor from a VAZ has a lot of advantages.

These include:

the farmer receives almost unlimited possibilities for adjusting parts as required by specific operating and weather conditions;
Any Zhiguli model is suitable for assembling a mini tractor: VAZ 2101, 2102, 2104, 2106, 2107, 2108, 2109. The engines of all these machines are reliable, durable and unpretentious to the quality of fuels and lubricants. In addition, they are very easy to operate and maintain;
the farmer can choose any type of chassis for a mini tractor - a solid welded structure or a broken one, fastened with hinge mechanisms. This will allow you to operate homemade equipment in different road conditions - on a flat surface or for driving over rough terrain;
during further operation of a mini tractor with a VAZ gearbox and axle, its owner can always purchase any replacement parts in case the standard parts fail.

Of course, assembling a mini tractor will take time and effort. However, this will allow you to save a significant amount, while obtaining a reliable and productive agricultural machine. Provided the correct procedure is followed, the farmer will be able to assemble a high-quality mini tractor, which in terms of characteristics will be practically not inferior to most factory models.

How to make a mini-tractor from a Lada with your own hands

Let's look at how to make a homemade tractor from a VAZ, what materials and tools will be needed. First of all, you need to complete drawings and diagrams of all structural components. To make a mini tractor with your own hands, you need exact dimensions of parts and calculations. Each component must be described separately. And you need a drawing of the assembled tractor. What the homemade tractor with the VAZ 2106 engine will look like depends on the diagrams and drawings made.

While working on the drawing, you should consider the following points:

it is necessary to determine the location of the gearbox;
the engine must be covered with a protective casing;
where will the fuel tank be installed?
if you shorten the tractor frame, then a homemade mini tractor from a VAZ will consume less fuel;
The front suspension should be reinforced.

If you decide to create a tractor from a VAZ 2109 or VAZ 2106, then as a result of the work done you will get a fairly powerful unit that will cope with many agricultural jobs and help care for your garden and plants.

So, we begin the actual development and assembly of a homemade tractor based on the VAZ. A mini-tractor can be made with an engine from a VAZ 2022 or VAZ 2106, or borrow additional parts from other car models.

For example, the gearbox can be borrowed from a GAZ-53, the rear wheels can be taken from an MTZ-82 tractor, but the front wheels can be removed from an already inoperative or unnecessary walk-behind tractor or cultivator.

You can also buy them in the store. You can take the steering and driver's seat from any Zhiguli model, or make it yourself. The front and rear axles are taken from the Zhiguli unit.

Where to begin?

As a rule, the construction of any homemade product begins with the creation of a drawing. The diagram will help you accurately calculate all dimensions, mark connection points, outline the shape and number of parts. Without a drawing, by eye, you are unlikely to be able to do everything correctly and efficiently the first time. Therefore, do not neglect this stage.

When working on a drawing of a mini tractor from Zhiguli, consider the following points:

the front suspension should be made stronger;
the engine must be placed under the driver's seat;
be sure to indicate changes in the chassis;
the motor in a Zhiguli mini tractor must be covered with a casing;
mark the location where the fuel tank will be located;
if you create a shortened frame, the tractor will be compact and economical in fuel consumption;
if you decide to reduce the frame, then keep in mind that the bridge will also be shifted.

Stages of work on making homemade products

The next thing to do is to highlight the individual stages of work:

The kinetic scheme is an important stage in creating a mini-tractor with a VAZ engine.
Creating a tractor frame. It can be made from channels and corners. All frame joints are carefully welded. Now you should inspect the metal for rust and coat the frame in several layers with a metal primer.
They are starting to finalize the project's chassis. It is imperative to check the brake system and, if necessary, replace its components.
Wheel installation. If you are going to install large wheels in diameter, then you need to take care of the axles and brakes by altering their structure.
After this, the engine is mounted on a previously prepared frame, which has already completely dried after painting with primer, the protective casing for the mini tractor from the VAZ is welded and mounted.
They install the seat, steering and create platforms for mounting attachments.

But you don’t have to make platforms for hanging, but just make a snow dump. But you still need to attach a 50 kg counterweight at the front so that the unit does not tip over under heavy loads at the rear. You also need to attach headlights of your choice.

A hole for a trailer would also come in handy. With its help you can hitch a cart or other cargo. The next important element, without which the VAZ 2106 mini-tractor will not move, is the battery. You can use a regular car battery. For it, you need to weld or make a storage compartment out of plywood. It is better not to attach the battery tightly in place, but to make it removable so that it can be charged. After all, it is much more convenient to take the battery and bring it to the garage than to drive the car. Think through every detail to create a mini tractor with a VAZ gearbox with a Zhiguli engine.

Preparatory stage of work

Creating a mini tractor with your own hands with a VAZ engine should begin with preparing drawings. As an example, you can use the figure below:

When creating drawings, immediately decide on the location of the gearbox and fuel tank. Provide a protective cover for the motor. It is advisable to strengthen the front suspension and shorten the frame. This will reduce the fuel consumption of the unit.

It is better to take components from one technique. This will facilitate possible repairs and operation in general. But if the quality of some components or parts is in doubt, you can use spare parts from other equipment. For example, the gearbox can be taken from a GAZ-53, and the rear wheels can be taken from a MTZ tractor. The axles, steering wheel and operator's work area can undoubtedly be borrowed from the selected VAZ model.

Where can you use a homemade mini-tractor?

A homemade mini tractor with a VAZ engine can be used in the garden on large plots of land. The homemade product can perform a large sector of agricultural work: from plowing, harrowing, soil milling, planting and plowing potatoes, snow removal, grass mowing to the most difficult work, such as harvesting and loading hay.

To summarize, we can answer the question of how to make a mini tractor from a Lada with your own hands. Creating such a mini-tractor is not very difficult, as it seems at first glance. After all, it is a very useful machine for farming. Moreover, a device made by yourself is in no way inferior to a factory one. It will be even stronger and more reliable, and most importantly, it will cost much less than in the store.

Important points

If you decide to make a homemade mini tractor from a Zhiguli, you should know some important points. This technique will be a great help, and you won’t have to spend a lot on its production. But you should consider some legal important points:

If you buy an old Lada for homemade purposes, then a re-registration procedure must be carried out;
After this procedure, you must notify the traffic police about the planned work. An act of surrender of the rooms will be drawn up there;
After you create a mini tractor from a Zhiguli, you need to register it and get new license plates. But most often, farmers use such transport exclusively within their own area or between fields, so such registration can be avoided.

As you can see, making a mini tractor from a Zhiguli is quite simple. It is only important to think through every moment, prepare all the necessary parts and tools. Many owners of such homemade products note the excellent performance of the machine and its capabilities in working in the fields. But the important thing is that you assembled it yourself, and therefore, if a breakdown occurs, you can easily find and fix it.

Tools and materials

A small tractor greatly helps farmers in their work. They can cultivate the land of household plots and summer cottages, and harvest crops. The big advantage of the unit is that a wide variety of attachments can be connected to it. A compact mini-unit is good for everyone, but it costs a lot of money. Even Chinese manufacturers have begun to significantly raise prices in recent years. Therefore, some craftsmen make small units with their own hands, and the quality of these mechanisms is not inferior (sometimes even superior) to factory products.

Before starting such work, you should understand how this or that unit is structured, how it works, and what its features are. Such equipment on a farm is needed, as a rule, for 3-4 types of work, so when creating a unit you can “place accents”, for example, strengthen the frame (if it will bear an increased load) or install wider wheels if the main work will be carried out in field.

Making a mini-tractor is quite simple; it will not be much different from a real tractor. First of all, you should make a plan of how to create such a unit. There are many used spare parts on the market for motorcycles, VAZs and UAZs, so finding a suitable unit will not be very difficult.

The beam/bridge can be made with additional fasteners, since often factory analogues do not have the required strength coefficient. A homemade tractor may have no cabin, but this is not always justified, especially when working in hot or cold seasons. The PTO is a power take-off shaft that makes it possible to operate mounted implements. Types of shafts:

mating,
autonomous;
working synchronously.

The frame can be made from “6” angles or pipes with a diameter of 45 mm. To make the structure more stable and durable, metal plates (6 mm thick) are welded at the corners. The gearbox can be taken from VAZ. It is important that in its working condition there are at least three forward speeds and one reverse. Traction can be “borrowed” from a motorized stroller. The steering column is quite suitable for a domestic car like “Zaporozhets”. It is also possible to make a mini-tractor with different engines - both single-cylinder air-cooled and four-stroke carburetor. Such power plants are ideal for creating agricultural machinery.

The benefits of creating a miniature tractor with your own hands:

low price;
you can make a unit that best suits your personal needs.

The disadvantages include:

the process of creating a tractor may seem labor-intensive for those who have not worked much with machinery;
car engines run on gasoline, which is more expensive than diesel fuel;
You are not allowed to drive on federal highways using this type of vehicle; you may receive a fine.

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.

How to do it yourself?

Creating a miniature tractor begins with installing a frame, which can be made from tubes. Such a design should be made powerful, but at the same time it should not be very heavy. Often the frame is made double. Units with the so-called “breakable” frame with all-wheel drive from the GAZ-52 are also popular. The “breakable” frame makes it possible to turn the tractor along a small radius, which increases the maneuverability of the device. The most important blocks of a mini tractor:

A mini-tractor made independently at home begins with the development of drawings and a diagram. Taking a “related” project as a starting point, you can edit it and make your own adjustments. After an individual project has been prepared, it is drawn on a piece of Whatman paper. Next, you will need to assemble all the necessary components to make the basis of the future unit. The dimensions of the frame may vary depending on the purpose of the machine - it can be 1.5-2.5 meters long, 1.3-1.8 meters wide.

A very important component is the hydraulic drive; it provides many advantages in operation and makes it possible to control a wide variety of equipment. The hydraulic unit is especially valuable in this regard. Its presence will allow you to use a wide variety of attachments - from KUN to snow brushes. Hydraulics consists of:

hydraulic cylinder 76x80;
distributor P82;
pump NSh12.

The pump runs at 1000 rpm and sometimes needs to be turned off. Things are not complicated with the engine; the power plant can be installed from any car or motorcycle.

The UD 25 engine is a good engine. It is a two-cylinder unit with a capacity of 12.2 liters. s., engine volume – 0.43 liters. The model is very successful, although it is no longer produced, but there are a huge number of similar units on the secondary market. This model costs no more than 8 thousand rubles. The gearbox can be taken from a VAZ or Ant engine. If the tractor is used in field conditions, then it is rational to take 20-24-inch wheels. The front beam is prepared simply:

two “cams” are assembled, which can be taken from a Zhiguli;
a square is made from a pipe (45x45 mm) by welding;
Corner-posts “4” are attached to the frame by welding, turning “cams” are mounted and secured to them, and the steering is installed.

The beam of the mini-unit has a swinging mechanism, which is taken from the VAZ together with the cross. You can also take a similar element from UAZ. It is very important that axles have congruent gearboxes. This must be done so that the wheel rotation coefficient is the same. The gearbox is taken from any car. With 2 boxes the mechanism will be even more functional.

Do-it-yourself homemade tractor: types, configurations, assembly instructions

Most people associate work in agriculture with cultivating land. But in order to sow and grow crops, berries and vegetables, as well as fruits, it is necessary to plow the soil, supplement it with fertilizers and provide watering, as well as weeding. If the farmer has specialized equipment, the work can be greatly simplified. Such equipment is small in size, but copes with basic tasks quite successfully. Among them are:

loosening;
plowing the land;
mowing grass.

Firms and large agricultural complexes approach solving this issue using domestic and imported models. If you are the owner of a private farm, you may be limited in your financial capabilities. In this case, you will have to use a mini-tractor, possibly made independently.

This will save money, but you should be prepared for the fact that assembling such equipment is accompanied by certain difficulties. This does not stop many, because every farmer has the power to make such a mini-tractor on his own, additionally equipping it with equipment to solve a wide range of problems.

The main types of homemade tractors

A farm tractor can belong to one of several varieties, including:

multifunctional equipment;
homemade tractors with the function of collecting garbage and mowing grass;
riders.

The first type is equipment with which you can cultivate the soil, remove debris, and also cut grass. Homemade tractors are usually equipped with medium-power power units. Multifunctional equipment can cope with an area of 6 hectares. If necessary, you can install attachments on it, thanks to which the list of tasks expands.

Homemade tractors on wheels can be designed to perform a narrow range of tasks; they are used to cultivate an area of up to 2 hectares or create lawns. Riders are necessary for applying fertilizers, as well as treating with pesticides. They can use the equipment to perform other tasks when there is a need to cultivate a small plot of land.

Tractor manufacturing features

If you decide to make a homemade tractor with your own hands, then at the first stage you will need to make a frame for which a rolled channel is used. The design contains traverses, and they should be located at the back and front. In addition, the system has side members. When the frame is created, the width of the front part is slightly reduced, which gives the part a trapezoidal shape. A hole must be created in the frame, thanks to which other devices and elements can be strengthened.

Work methodology

When making a homemade tractor with your own hands, it is necessary to use racks that must be welded to the corners. They will serve as a subframe. They should be additionally connected at the top. You need to install the rear axle on the frame.

Sometimes a project involves assembling a four-wheel drive tractor, in which case the front axle must be located on the frame. A homemade tractor is made with your own hands using an engine. The most suitable option would be a motorcycle engine. To mount the gearbox on the frame, you need to find a place. The box should be positioned so that it is more convenient for the driver to control it.

Now you can begin installing the steering components. A steering wheel is usually used for this. This part is usually borrowed from a domestic passenger car model. In some cases, a motorcycle handlebar is used. A trailer will need a towbar. It is installed at the next stage, welded to the frame. When making a homemade tractor with your own hands, you need a brake system and a tank, which must proceed to connecting the electrics.

Further work

If we continue work on further designing the ATV, then the motorcycle (for example, Ural) must be disassembled and the frame rebuilt. To do this, move the seatposts (pipes) back by 4 centimeters. And you will need to weld the Zhiguli bridge you cut to the Ural pendulum and attach it to the frame. And the lower fork of the motorcycle and the rear struts should be cut off immediately behind the saddle post pipes.

By the way, to create the planned homemade product, they take from the Zhiguli not only the rear axle, but also the steering knuckles for the front suspension, the brake system (removing the vacuum booster and handbrake), and forced cooling for the engine is used from the VAZ 2108. The steering wheel comes from the motorcycle, but further design for the steering wheel - a column, lever rods, a bipod - everything is from VAZ.

Wheels are a special issue

. They are constructed using the base from VAZ wheels, adding powerful tires with treads, like for an all-terrain vehicle. Then the homemade vehicle will be able to overcome traditional forest or field off-road conditions.

Assembly instructions: frame

A homemade tractor may seem disproportionate and unsightly. In fact, if the mechanism is assembled correctly and all the key components are arranged rationally, then the system will work properly, performing all the tasks assigned to it. Traverses act as additional elements of the frame.

The spar is assembled from successive stages, the inner ones consisting of a square steel pipe, while the outer ones are made of a channel. The front traverse should be smaller than the rear. This indicates that a 12-gauge channel will fit the front crossmember, while a 16-gauge channel will fit the rear.

Powertrain, axle and track

Before you make a tractor, you must select a motor of the required power and torque. Sometimes a four-cylinder diesel engine with a power of 40 hp is used for this. With. This unit is water cooled. As for the bridge, it can be installed without additional adjustments. It can be borrowed from a domestic truck and integrated into homemade equipment.

Additional equipment of the tractor with an engine

A homemade tractor with a VAZ engine can be found quite often, as well as installations of the following types:

You can equip the tractor with an engine from a Moskvich or Zhiguli car. When it is intended to make a homemade product according to the 4x4 formula, for the M-67 the transmission gear ratio is increased. Otherwise, the power plant will lack power to provide force to the wheelsets. It must be taken into account that the power unit may require an additional cooling system.

Additional transmission information

A homemade tractor with a VAZ engine can be supplemented with a power take-off shaft and gearbox, which should be borrowed from the GAZ-53 car. The clutch can be taken from GAZ-52. These nodes cannot be used in finished form. Adjustments must be made.

In order to synchronize the engine with the clutch, you need to prepare a new clutch basket, adjusting it to the dimensions. The rear plane of the engine flywheel is shortened, and an additional hole is drilled in the center. These manipulations can be performed on a lathe.

The circumcision process itself

To ensure the compact design and maneuverability of the future homemade product by reducing the turning radius, you need to shorten the rear axle taken from the Zhiguli. At the beginning of the operation, cut off the cup for the spring and pull out the end flange.

Part of the removed axle shaft (take measurements according to the drawing) must be cut off with a grinder and left. At the end of the segment we make a notch where the groove for the “male” will be made. A hole will be drilled inside the cup. The axle shaft is joined together and welded according to the markings.

Next step:

A solid welded axle shaft is driven into the bridge. And welding is carried out with a chamfer for the weld seam. We perform the same operation on the other side.

What else you need to know about the rear axle and wheels

A mini-tractor for snow removal can be equipped with a rear axle from a truck or car. The axle shafts are pre-shortened on a lathe. If a ready-made bridge cannot be found, then designs from different machines can be used. Experts recommend using any unit that fits in size, because the front axle does not act as a drive axle.

Wheels should be selected according to their radius. If the equipment is intended to be used for transporting goods, then it is better to choose disks whose diameter varies from 13 to 16 inches. For equipment that will be used for agricultural work, you can use wheels with a radius ranging from 18 to 24 inches.

Results

We can conclude from all of the above that the problem of how to shorten the rear axle of a VAZ, in fact, is not that difficult. The main thing here is to be well prepared for the work, have the appropriate tools (in particular, a grinder and welding) and be able to use them. You also need to have pre-prepared drawings of the future design. Well, and of course, measure everything carefully so that you don’t have to adjust it with the help of mechanical influences and a few obscene words.

All in all:

have a clear idea of what you want to build from spare parts purchased at a disassembly site - an ATV, a go-kart or a mini-tractor for farming. And then the work of trimming the rear axle can be easily completed as a certain stage in the construction of the intended homemade product.

Equipment for a homemade tractor

The described equipment includes a frame for a homemade tractor. After assembly, it is necessary to install the drive wheels and road wheels. The power unit is installed at the next stage, then comes the turn of the gearbox. The differentials and onboard brakes should be installed in the next step, after which all components can be connected to the gearbox.

The next step will be assembling the controls, as well as arranging the workplace. Additional parts and tracks can be installed in the next step. Now the master will have to check the performance of the tractor, modifying its individual components, if necessary.

How to make a homemade mini tractor

Good day, lovers of homemade products on the site for craftsmen! I want to share with you information about how I made a mini tractor with my own hands.

It all started with the fact that I bought a LuAZ (Volynyanka among the people), they wanted to sell it for scrap. The engine was killed (the engine on this car was from a Cossack), the body was rotten, but everything else was almost in good condition. I took the gearbox, steering mechanism, axles and wheel gears, electronics, and cut everything else and sold it for scrap. There I returned some of the money spent.

Homemade mini tractor with a diesel engine from a Sadko DE-300 walk-behind tractor and 4 6x12 wheels.

I welded the frame for the mini tractor from a 40x40 profile, but later I strengthened it (welded 2 40x80 profiles).

Over time, the “skeleton” began to grow and began to look a little like a homemade tractor or mini-tractor.

The engine was combined with a belt drive gearbox. I used 2 belts, profile B, and reduced the speed with pulleys by 3.5 times.

Now I’ll tell you about hydraulics for a mini tractor

. I installed an NSh-10 pump, a P80 distributor, and a 75x110 hydraulic cylinder. The pump does not work all the time; I can turn it off if I wish. To do this, I made a switchable drive from parts of the Ural motorcycle gearbox. I removed the shift fork, shaft, two gears and splined clutch. The shaft had to be cut and then extended by 5cm so that the sprocket could be put on. The drive housing was welded from a 40x40 angle, the sprocket and chain were used from an IZH Planet motorcycle. The drive was filled with oil, so the housing was sealed and a seal was placed on the shaft.

The pump operates at 1000-1100 rpm, the shaft rotating it comes from the clutch flywheel.

How to make a mini tractor from a VAZ - assembly steps

The correct sequence of actions when assembling a mini tractor from a VAZ is one of the most important conditions on the path to manufacturing a high-quality machine. To avoid the risk of making a mistake, each of them should be studied in more detail.

Making a strong frame

One of the first and most important procedures. The more reliable and durable the frame, the more stable a homemade mini tractor with a Zhiguli engine will be. Provided that a high-quality and balanced frame is created, the agricultural machine will be able to overcome various obstacles in the form of hummocks, deep puddles and fallen stumps on rough terrain.
