✅ Homemade bulldozer on MTZ 80: step-by-step instructions, necessary materials and tools, drawings

Compact crawler bulldozers today occupy third place in the global production of special equipment, second only to hydraulic bucket excavators and wheeled bucket loaders. This is explained simply: there is simply no more universal earth-moving equipment used in various industries, agriculture and public utilities, as well as construction.

These machines have long been appreciated abroad, where their production and operation began back in the 60s. last century. What can we say if now every self-respecting Western farmer has a similar vehicle in his garage. And although in the USSR there were also attempts to organize mass assembly of small tractors, they did not become widespread. Well, in Russia they are just beginning to understand what great capabilities mini-bulldozers .

Homemade bulldozer on MTZ 80: step-by-step instructions, necessary materials and tools, drawings

Most craftsmen have a chainsaw in their arsenal.
However, this tool can be used extremely rarely or even lie idle. But the garden needs to be cultivated regularly, wasting both time and your precious energy. If you're a jack of all trades, you can make a walk-behind tractor from a chainsaw. How to do this, what tools to use, what needs to be taken into account when creating drawings - you will find answers to all these questions in our article. In addition, we will tell you how to make a walk-behind tractor from a Druzhba chainsaw.

Where do you need to start?

If you have a very small plot, it is not justified for you to buy an expensive walk-behind tractor. In addition, such equipment requires careful maintenance, the purchase of additional lubricants, fuel and parts. If you have a chainsaw, you can easily upgrade it.

The chainsaw has compact dimensions, light weight, but at the same time quite high power. That is why it can act as a universal drive to create a walk-behind tractor for cultivating the land.

The entire stage of converting a chainsaw into a walk-behind tractor takes place in several stages:

creating a drawing. Without this, you will not be able to make truly high-quality equipment. On the diagram you should indicate all the parts, their attachment points, and clearly calculate the dimensions;
frame manufacturing. It should be made of a cube with angles of 32 by 32 millimeters;
the motor is mounted on the transverse upper frame corners, and the fuel tank is mounted slightly lower using brackets;
in front there are also vertical posts needed for intermediate shaft supports. To mount the bearings, you need to install special supports at the longitudinal corners.

How to make a walk-behind tractor from a Druzhba chainsaw?

Basically, all owners of private houses have a Druzhba chainsaw. Based on it, a quite high-quality walk-behind tractor is obtained, the speed of which will be 2.5 kilometers per hour in 1st gear, and the power will be about 4 horsepower.

The process of creating a walk-behind tractor is exactly the same as from a chainsaw of another brand, and it was described in the previous section. There are, of course, some differences and features.

Making such a unit is quite simple. First of all, you need to very carefully attach the RU-32 collar flange to the main shaft. It is necessary so that you can attach an axle gearbox, the shaft of which is taken from the UAZ axle. You can increase the gap between the ground and the gearbox axle using a double-row chain and two sprockets from a VAZ.

The motor from the Karpaty moped easily acts as a gearbox and gearbox. Centrifugal clutch is standard. A steel pipe is used to fit onto a cutter or wheel axle.

This technique has many advantages:

suitable for small plots - 15-20 acres;
there are no special requirements for lubricants and combustible materials;
The operation is autonomous, so you can use the unit almost anywhere.

As can be seen from all of the above, making a walk-behind tractor from a Druzhba chainsaw or from any other brand is very simple. All you need is some skills in metalworking and turning, as well as having all the necessary tools and materials available.

Homemade blade at MTZ 6 important tips

The MTZ-82 tractor, as well as their versions and modifications, is our “everything” in peasant farms and various enterprises, both in central Russia and in the Urals and Siberia. The design of this tractor has not undergone significant changes since the beginning of its serial production more than 40 years ago at the then Minsk Tractor Plant. IN AND. Lenin (and the MTZ-80 (82) tractor itself was a product of a deep modernization of the even more “ancient” MTZ-50 tractor). A huge number of trailed and mounted equipment suitable for this tractor makes it indispensable and truly universal.

Are there any advantages to homemade dumps? Yes, there definitely is!

I will make a dump better than at the factory

Actually, it definitely won’t work out worse than Roskomos’ missiles. And at the same time, we come across some really interesting samples. However, before you start “fencing” the dump, prepare a technical drawing or even a drawing, make a list of what you will need to put the dump into operation, what you have, and what you will have to buy in addition. Here is a list of spare parts for a municipal dump to help you.

Tip 1 : Carefully calculate everything, do not start work and especially do not buy anything until you have made a complete list.

A homemade blade is much cheaper than factory options;

But this is not a fact! The dump will be more or less profitable if you have access to an unlimited amount of metal. Moreover, for nothing, free of charge, on the ball. Moreover, you need at least several types of metal. For example, the LEKS plant uses up to 8 to produce its most powerful hydraulic rotating bulldozer blade in Russia! types of sheets of high-quality metal 09G2S, and you also need a pipe, square, etc. But you will also need hydraulic cylinders, hose hoses, hardware (all this comes complete with “factory” dumps).

Tip 2: it may only be profitable to remake something very similar to a blade, adapt a blade from another type of tractor with your own hands, or assemble one new one from several old products.

Components for a homemade tractor blade

A tractor blade, even one made by yourself, will not work without the components that drive it and also attach it to the tractor. And there is one more nuance with them. A large manufacturer of attachments gets everything! components with huge! discount, and also saves very significant funds on their delivery, because he receives them in large quantities. These prices are most often lower than the purchasing prices of any trading company, and can differ significantly from retail prices. Moreover, the quality of these components is on average higher than those sold in retail stores, and their service life is longer. You can look at prices for components (hydraulic cylinders, hose hoses, hardware, technical plates) on our website - they are current and one of the lowest on the market.

Tip 3: Choose high-quality components for dumps, for example, in our online store.

Selecting the optimal dimensions of the blade structure.

It’s hard to argue with this - if you want a blade 3 m wide, yes please. However, it will be very difficult to operate such equipment on public roads (we remind you that the maximum size is 2.55 m), problems may arise with traffic police and Gostekhnadzor employees, and the load on the components and assemblies of the tractor itself will likely increase.

Tip 4: Even “homemade” products are better made in standard sizes for safety

Non-standard size blade for MTZ tractor

Certificates of conformity, problems with Rostechnadzor

In general, the use of a homemade blade on a tractor is considered unsafe and the operation of equipment with homemade modifications is prohibited. A decision on this can be made by engineers-inspectors of state technical supervision, since they are responsible for supervising in the agro-industrial complex over compliance with the rules of operation of machinery and equipment in terms of ensuring safety for life, health and property, environmental protection, as well as the rules regulated by standards, other regulatory documents and documentation and supervision in the agro-industrial complex over compliance with the established procedure for organizing and conducting certification of work and services in the field of technical operation of supervised machines and equipment. At the same time, state engineers-inspectors of state technical supervision are given the right to: conduct inspections and, on the basis of them, prohibit the operation of supervised self-propelled vehicles and other types of equipment, the technical condition of which does not meet environmental protection requirements or does not meet safety requirements; give mandatory instructions (decrees, representations) to legal entities, officials and individuals to eliminate violations on issues within the competence of state technical supervision bodies; draw up protocols on administrative violations, impose administrative penalties in the prescribed manner within their competence.

Making a shovel

To make a shovel, steel with a thickness of at least 80 mm and pipes with a diameter of 70 mm or more are used.
The prepared steel sheet is cut in the longitudinal direction, but not in the center, but closer to the edge, approximately ? from the central section. This marking allows you to give the bucket exactly the shape that is most suitable for carrying out the planned work. As for the width of the blade, the choice of this parameter can be arbitrary; there are no exact dimensions. Although there is an unwritten rule here - the protrusion beyond the external dimensions of the tractor on each side should be no more than 40 cm. Exceeding this size will create a certain discomfort and inconvenience when operating the vehicle. Since the blade experiences significant mechanical loads during operation, for greater reliability It is recommended to carry out additional strengthening. It is performed using an ordinary steel pipe with a square cross-section of approximately 40x40 mm. It is welded in a longitudinal position just below the middle of the shovel. In addition, the homemade structure is also strengthened with 4-8 transverse stops, which makes it possible to give it maximum strength and stability. It is recommended to wrap the lower edge of the blade with a rubber casing, which will avoid damage and deformation when it comes into contact with the surface.

Mounting system and hydraulics

In addition, the shovel needs a reliable mount connecting it to the tractor, as well as a hydraulic complex, through which it will rise to the required height. They begin work by welding the fastening structure itself, which looks like the letter “A” and is reinforced with longitudinal stops, in the center of which a special bracket is welded. To raise/lower the mechanism, it is recommended to use a ready-made hydraulic cylinder, attached to the frame on one side and to the tractor on the other.

Homemade bulldozer at MTZ

A homemade blade based on the MTZ tractor will become an indispensable tool for any farmer: planning and snow removal, creating terraces, construction, and so on.

With the right approach to construction, such a dump will have many advantages:

Thanks to independent selection of parts and construction, in the future it is easy to independently service and repair the equipment, and, if necessary, modify it;
You yourself select the optimal blade size for you and your machine;
If you have a large amount of unowned material and the necessary tools, it can cost much less than those sold on the Internet;
Most of the blades that are offered on the Internet are made independently, for this reason, if you have certain skills, you can build a bulldozer at least as good as those offered.

However, a number of disadvantages can be noted:

In the event of a breakdown of equipment or tractor, there will be no one to turn to for warranty claims;
If you select the wrong blade size, you can severely overload the machine, which will lead to fatal breakdowns.

Classification of mini bulldozers

In world practice, these machines are classified according to three main criteria: engine power, traction power and weight. Based on them, all compact crawler bulldozers are divided into light, medium and heavy. Moreover, they are assembled on two different platforms. The first two modifications are made on the basis of arable tractors, and the third - on the basis of industrial models. This is connected, of course, with their functionality and future purpose.

Thus, mini-bulldozers of light and medium categories have an engine power of up to 130 hp. pp., working weight of about 11 tons and draft class 1-4. These types of machines are capable of performing a wide range of tasks: moving soil, digging pits, constructing embankments, backfilling trenches, leveling, as well as cleaning and preparatory work in construction and agriculture. And although the equipment of the first two categories does not have the highest capabilities for its aggregation with various attachments, nevertheless, it is ideal for not very complex and labor-intensive work.

Currently, the production of light and medium compact crawler bulldozers, which, by the way, is quite simple, fast and does not require large investments, is carried out by: Volgograd Tractor, C. F. Struck Corporation (USA), Kazakhstantractor and, under license from the same plant, Chinese YTO International company, and a number of lesser-known domestic and foreign enterprises.

In recent years, interest in heavy industrial mini-buldozers . Primarily due to the rapidly expanding area for their application. Especially where the use of manual labor is decreasing due to its rise in cost. For example, quarrying and mining work, cleaning the holds of sea vessels, excavation work in the tundra, the Arctic, etc.

The capabilities of these compact, energy-rich machines are very wide due to their design features. Firstly, excellent compatibility with a large number of attachments. Secondly, the presence of hydraulic units, as well as the possibility of replacing metal tracks with rubber ones. Thirdly, the driver's cabin has ROPS protection and a microclimate system.

The growing popularity of heavy mini-bulldozers is also reflected in the number of companies involved in the development and production of this equipment. Unfortunately, there are no Russian enterprises on this list, but there are quite a few foreign ones: Case, Caterpillar, Daewoo, Dressta, Hyundai, Hitachi, HSW, John Deere, Komatsu, Shantui, XCMG, Walbon, etc.

Necessary materials

Before you start and select materials for a bulldozer on MTZ 80 or 82, you need to draw up a plan and drawing. To select the optimal size and weight of the blade, it is necessary to take into account exactly what materials you will have to work with, as well as the weight and power of the tractor.

Tools

In this case, not many tools are needed: these are wrenches, a metal cutter and a welding machine. The most important tool will be the person, since the final result will depend on his skills.

Materials

Perhaps the main material will be sheet metal, which will be used both for the frame for the bulldozer and for the blade itself.
The size must be calculated based on the expected loads or simply copied from existing models. Two thick beams are needed for the half frame. You will also need 6 swivel joints, as well as one hydraulic cylinder. You also need to take two metal pipes with a diameter of approximately 100 mm and 4 swivel joints.

However, if you are going to make a rotary blade, you will have to pick up two more cylinders instead of two metal pipes. This will allow you to adjust the rotation of the blade and expand its functionality.

Step-by-step instruction

The entire process of manufacturing a homemade bulldozer at MTZ consists of the following steps:

First, you need to make two brackets that will be connected by a cross beam. This entire structure is attached to the side members with bolts. Secondly, plates with a stiffener and a hinge joint at the bottom are welded to the brackets.

Homemade bulldozer diagram

Now you need to attach the hydraulic cylinders. It is better to make them parallel to the subframe, since the load on the blade will be greatest in the lower part. The blade is divided into two parts with the center on the hinges of the half-frame. The remaining halves are divided into 3 parts, and 1/3 from the center is selected for attaching the hydraulic cylinders. Another option is to cut out a set of pipes. Two pipes are the same length and two are different. By changing them you can adjust the rotation of the blade. This will cost less than hydraulics and will serve much better than a fixed blade, although it will require more preparation time. The pipes will be attached to the hinges, which will greatly facilitate their installation.
However, if you do not plan to change the position of the blade, you can use two pipes instead of cylinders, which are permanently welded to the blade and half-frame at the hinge points. The central ones can also be simply brewed.
