How to make a mini tractor from a Neva walk-behind tractor

Minitractor from the Neva walk-behind tractor. Overview of options

If a farmer has a walk-behind tractor, gardening work is much easier. However, walk-behind tractors have one drawback and that is that you have to walk behind them. And when it is necessary to carry out work on large areas, the legs are subjected to very great physical stress. To facilitate this process, many craftsmen are converting their walk-behind tractors into mini tractors.

Almost all Neva walk-behind tractors have sufficient power to be converted into a mini tractor. Many people believe that this is a labor-intensive process that requires practical skills, but this is not entirely true. On the Internet there are a large number of different drawings and diagrams for making a mini tractor from a Neva walk-behind tractor. These drawings have already been assembled by someone else, and their plausibility and correct dimensions have been confirmed by someone else's experience.

This is approximately what a mini tractor assembled from a walk-behind tractor looks like and its operation:

Design features and advantages

The homemade Neva mini tractor, made from the walk-behind tractor of the same name, has a number of the following features, which are also its advantages:

Minitractor from the Neva walk-behind tractor

• Cheap components and spare parts - in addition to the walk-behind tractor used, assembling such a mini tractor will not require significant financial investments and the purchase of expensive spare parts. When assembling such equipment, parts of the suspension and steering of old Soviet cars or foreign cars are used. The frame and frame are made of any durable metal.
• Ease of manufacture - in order to assemble such a small tractor, you need minimal skills and theoretical knowledge of working with a welding machine and other electric tools (grinder, screwdriver, drill, etc.).
• Compact placement in a small garage - compared to other factory-produced mini tractors, such a homemade product will not require a large room for storage in the off-season.
• Convenience when working in small areas - thanks to its small size and convenient steering, this equipment can be used in confined spaces in summer cottages and medium-sized greenhouses, performing soil cultivation and other work more efficiently and quickly.
• Multifunctionality - such a mini tractor, thanks to the presence of two axles and stable traction with the soil, can be used for various types of field work: from plowing to hilling and harrowing. Also, compared to a simple walk-behind tractor, this technique can be used not only with standard walk-behind tractors, but also with more spacious and heavy-duty vehicle trailers.
• Low fuel consumption - the consumption of gasoline or diesel fuel, compared to factory-produced mini tractors, for such a unit is 1.5-2 times less;
• High speed – a lightweight mini tractor can reach speeds of up to 30-40 km/h.

On a note. The production of such a mini-tractor in most cases comes down to attaching the so-called front adapter with a seat, steering, and an axle with two wheels to the walk-behind tractor. At the same time, the production of such a device will cost several times less than factory models; it will turn the minitractor not into a single piece, but into a breakable (composite) unit with complex steering.

We make a mini tractor from a Neva walk-behind tractor with our own hands

If you have skillful hands, then you can minimize financial costs by making a mini-tractor from a Neva walk-behind tractor with your own hands. The alteration will not take much time, and the result will be a unit capable of performing almost any work on the site. For convenience, you can purchase other equipment for the adapter.

When converting a walk-behind tractor into a mini-tractor, you can use parts from unused equipment; it may take more time, but it will be cheaper.

To create a mini tractor based on the Neva walk-behind tractor, you will need the following parts: corners, sheets of metal, the walk-behind tractor itself, pipes, two wheels, a driver’s seat, a welding machine, and hand tools.

General excursion into technology

Over the many decades of its existence, a wide range of walk-behind tractors has rolled off the assembly line of the Minsk Tractor Plant.
For those whose activities are closely related to plowing the land, the classic model MTZ 05 is well known. This walk-behind tractor, produced back in the Soviet years, is still in demand today, and it can be successfully converted into a mini tractor. However, the most suitable models for the production of prefracture are MTZ-12 and MTZ-09N. Firstly, these are the most powerful walk-behind tractors, which increases productivity. Secondly, the very design of the units allows them to be easily and quickly converted into a mini tractor. This saves your personal effort, time and money. A special feature of MTZ walk-behind tractors is that they are equipped with 2-cylinder diesel engines, and homemade mini tractors based on them are not three-wheeled, but four-wheeled.

How to assemble a mini tractor with your own hands based on the Neva walk-behind tractor - drawings and diagrams

Having a walk-behind tractor greatly simplifies tillage. But it is not always convenient to follow him while working. Considering that many models have sufficient power, their owners are trying to improve the design. Even for professionals it will be useful to know that it is not so difficult to assemble a mini tractor from a Neva walk-behind tractor. Drawings and diagrams for this will serve as the basis for making a reliable and multifunctional unit.

General recommendations

At the first stage, you need to decide on the optimal model of the power unit. It must have enough power to drive the homemade frame. It is best to use the Neva MB-23S 9.0 PRO model for this. Its four-stroke engine produces 9 hp. will provide the required traction for cultivating the land using mounted tools - cultivator, plow, etc.

Motoblock Neva MB-23S 9.0 PRO

If you have a model with less power, you can make an adapter instead of a full frame, as described here. It will be less functional, but will improve the comfort of using the walk-behind tractor.

What is needed to create a full-fledged mini tractor? Let's look at its main components first.

Frame. Made from scrap metal. Rotary mechanism. The simplest disc brake system. Seat and body parts. A hitch for installing attachments, a system of levers for controlling it.

Most of the components can be purchased at scrap metal collection points or car dismantling sites. In this case, you need to pay attention to quality and absence of defects.

First, they determine the functions that a mini tractor from a walk-behind tractor should perform. Most often, a universal scheme is chosen, which involves cultivating land and transporting goods. For the second option, you will need a trailer, which you can make yourself or purchase a ready-made model.

Blueprints

General kinematic diagram

To ensure the correct pairing of all structural components, a kinematic diagram is drawn up. It must describe in detail the connection points between the walk-behind tractor shaft and the wheelset. It is desirable that the drive be on the rear axle - this way the tractor will have better maneuverability.

It is important that all parts of the mini tractor are selected correctly. If necessary, they can be modernized - processed on a lathe. It must be remembered that the service life and performance characteristics of the future tractor will directly depend on the quality of the components.

When choosing a drawing diagram, you should pay attention to the rotating mechanism. This node can be of two types.

Body fracture. It is reliable, but the steering column must be located exactly above the unit. A mini tractor made according to this principle will have low maneuverability when cornering. Installation of steering rods. Their installation will require more time and factory components. But at the same time, it will be possible to choose the installation location of the walk-behind tractor (on the front or rear axle), and the turning angle will also increase significantly.

Having chosen the optimal design, you can proceed directly to the manufacture of the unit.

Mini tractor frame drawing

Making a frame

To assemble the structure yourself, you will need a minimum set of tools and components. It is best to select the latter according to the diagram, and if any components are missing, make changes to the drawing taking into account the parameters of the replacement components.

Rolled metal for frame manufacturing. A square pipe, angles and channels are used. For the manufacture of the body, it is recommended to use a steel sheet with a thickness of 1.5 mm. Ready-made suspension and steering components. Welding machine, electrodes, grinder, drill, measuring tool.

Selection of walk-behind tractor

When choosing a walk-behind tractor in the Neva line for a future miniature tractor, you need to take into account the following parameters: power, weight, engine type, plow parameters, price aspects.

Power . It is determined by the area of ​​the zone where the work will be carried out. The larger it is, the more powerful the walk-behind tractor should be. The best option here is the Neva MB-23. Today it is the leader in power among all representatives of this line. Can also work on very hard soils. Creates a traction force of 180 kgf. Can unlock one of the wheels. Improves maneuverability. Engines of various powers can be installed in it. Today there is a very wide range of them. Thanks to this, each master will be able to choose the appropriate option.

Usually Neva MB-23 is presented in the following variations: 10.0 and 8.0.

Data of the first: Briggs&Stratton engine, its power is 10 l, the number of gears is 4 (2), the role of transmission is performed by a gear reducer filled with oil, suitable gasoline AI-92 and AI-95, processing parameter 86 - 127 cm, milling speed from 20 to 160 (per minute), carries out processing at a level of 20 cm. Second data: the engine is the same, only with the parameter 8 l, all other indicators are identical. Today you need to pay from 43,000 to 45,000 rubles for the Neva MB-23. The modification you purchase matters.

If you need a more modest unit, you can purchase the Neva MB-2. This is also a very productive technique, but with a less powerful engine. It has many modifications, for example “6.5 Pro” and “7.5 Pro”.

They are powered by the same brand of engine. In one modification its power is 6.5 liters, in the second - 7.5 liters. Their similar characteristics: a chain reducer as a transmission, suitable gasoline AI 95 and 92, processing level 20 cm, its width - 86-127, milling speed from 20 to 160 (per minute), weight - 98 kg, number of gears 4 (2 ). Distinctive indicators: – functional volume, in the 6.5 model it is 205 cc, in the 7.5 version it reaches 215 cc, – fuel tank, its volume in the first model is 3.8 liters, in the second – 4.6 . Today the price of Neva MB-2 is in the range of 33,000 - 45,000 rubles. Weight. The following rule applies here: the more complex the excavation work, the higher the weight of the walk-behind tractor, and the reverse principle. When choosing between a gasoline or diesel engine, base it on the factors that are more important to you. If you need a quiet device that starts quickly in cold weather, then give preference to the gasoline type. If you need a more economical device with stronger traction and stable speed, purchase the diesel version. This version also works better with difficult soils and large areas. Plow parameter. It depends on the depth of the upcoming processing. It is better to take a collapsible modification in which you can adjust the width. This way you can configure the plow for a given situation

Required materials and tools

To assemble a mini tractor from a walk-behind tractor with your own hands, you will need:

1. rolled metal to make a welded frame (square, channel, corner, and so on);
2. wheelset (with a solid axle or 2 axle axles);
3. wheel bearings;
4. a seat of suitable dimensions;
5. hardware for assembly (nuts, studs, bolts);
6. consumables for welding operations - gas, oxygen, wire, electrodes;
7. lubricants;
8. primer, paint for painting the assembled product.

Necessary parts for making a mini tractor

To carry out the work you will need a certain tool:

• locksmith - hammer, chisel, keys;
• welding machine for carrying out work on frame assembly;
• gas cutting kit if necessary;
• grinder for cutting and grinding metal elements;
• electric drill with a set of drills;
• taps and dies;
• devices for painting and anti-corrosion protection.

Turning equipment may also be required for working with a wheel pair.

Homemade mini tractors

Ideal for processing small areas. Almost anyone who understands technology, even at a minimal level, can assemble them.

How to make a mini tractor from a Neva walk-behind tractor

First, we purchase the walk-behind tractor itself, on which a hitch is already pre-mounted, either factory-made or home-made. Then it will be possible to attach trailers with a body, which can easily transport cargo, regardless of size. There are other additional details that add comfort during use:

1. Brake and gas pedals.
2. Seat.
3. Steering Wheel.

The volume of Neva walk-behind tractors is usually in the range of 6-8 liters. Therefore, a mini-tractor with such a base requires a minimum number of modifications.

If you have electric welding and a grinder along with additional tools, you can create a dump truck on your own. The main thing is to give a special design to the frame mount, and make sure that the mini tractor from the walk-behind tractor can tilt the trailer and turn it. The controls for these devices duplicate each other, so the walk-behind tractor can be used separately by simply disassembling the small tractor.

Homemade mini tractor from the Zubr walk-behind tractor

Of the required details:

• Frame.
• Cylinder with brake.
• Footrests, pedals.
• Steering column, complete with rods.
• The beam is in front, connected to the hubs and discs for the brakes.
• Wings at the back.
• Rear linkage with manual lift.

The last step is the joint assembly, using a hammer and drill, wrenches with a welding machine. Additionally, wheels are installed in front. The engine is attached to the frame at the front, so the minitractor maintains balance during operation. The power take-off shaft is located on the same axis with the pulley on the rear axle of the vehicle. Belt drive helps transmit power from one part to another. Belt tension and adjustment will be easier if the motor mount is floating.

Mini tractor based on MTZ walk-behind tractor

This walk-behind tractor has one difference from other standard models - it is equipped with a two-cylinder diesel engine. This causes the center to be heavier in the front when the device is actively operating. Because of this, the work process becomes noticeably more complicated. But you can fix the problem by doing the following:

1. We use the mode of operation with mowers.
2. The platform in front is completely dismantled.
3. It is replaced by a wheel from the front of the motorcycle, for which we use bolts. At the same time, the steering wheel is installed.
4. At the top of the frame there is a niche where the steering rod is installed. The adjusting rod must also be secured here, then the structure will receive an increase in strength and hardness.
5. We use electric welding to connect the platform and the mount for the driver’s seat.
6. The engine must have an additional platform where the hydraulic distributor with the battery is placed.
7. The rear part is connected to an additional metal frame for the hydraulic system.
8. The front motorcycle seat is ideal for handbrake placement.

Let's get a compact mini-tractor with three wheels.

Mini tractor made from Agro walk-behind tractor

As always, we prepare several basic parts in advance - the steering and braking system, additional wheels, and the hydraulic system. Hydraulics are needed for the system to work properly in conjunction with attachments. Extra wheels are easy to take from a regular car.

In the case of the Agro walk-behind tractor, additional steps will be needed to strengthen the drive axle shaft along with the wheel gearboxes. Let's assume that the engine of the device is located behind. Then the load will be distributed as evenly as possible.

Do-it-yourself mini tractor with a Centaur walk-behind tractor

Centaur walk-behind tractors are a type of professional equipment designed for agricultural work. Therefore, in the end, the mini-tractor will have high productivity.

The key component is the engine, with a power of up to 9 horsepower. It is necessary to use a metal profile to make a frame for this design. We install the seat along with the wheelset. Additional equipment in the form of a trailer is acceptable, which helps transport small-sized cargo. Other useful additions include single-share plows and moldboards.

Where to begin?

A homemade mini-tractor begins by preparing drawings and drawing kinematic diagrams. Drawings are needed in order to better imagine the future design and determine the necessary material.

Schemes are drawn in order to calculate the load on the frame and the traction force required to perform agricultural work. For example, the frame can be all-metal or fracture. The first option ensures reliability of the structure, and the second provides maneuverability.

The location of the engine also plays a role. The best option is when the power unit is located at the rear, behind the driver's seat. This will give the driving wheels of the vehicle more reliable grip on the ground, and the driver will add weight to the front driven axle. Thus, a homemade mini-tractor will not tip over when performing arable work on hard soil.

How to do it

Perhaps the most interesting option for self-assembly is a homemade 4x4 fracture mini tractor,

which is made on the basis of a walk-behind tractor. In general, this is a fairly common method of assembling a mini tractor, which proves its efficiency and performance during operation.

The video shows a homemade mini tractor with a walk-behind tractor engine.

Externally, this design looks rather cumbersome, but the internal contents are completely proportional, i.e. Every detail is in its place, precisely adjusted to the dimensions and parameters. Let's look at the design features in more detail:

Photos of drawings of units

• The frame structure will consist of two components - spars and traverses. Spars are made of three components. The front part will be made of channel No. 10, the last part will be made of a steel pipe with parameters 8x8 cm.
• The rear traverse will be made from channel No. 16, and the front one from channel No. 12. Cross members are made in the same way. In principle, all homemade all-wheel drive mini tractors have a similar frame design, with the same technical parameters.

• Almost any power unit can be used as an engine, the power of which will be sufficient to carry out agricultural work. The ideal option, in this case, would be to use a 4-stroke water-cooled diesel engine.
• The gearbox and power take-off shaft transfer case can be taken from a GAZ-53 car. The clutch will fit from a GAZ-52.
• When connecting the clutch and engine, certain problems may arise. We will have to re-make the engine flywheel, and also make a new clutch basket cover to fit it to the engine. The flywheel is ground on a lathe, cutting off the rear area, and also turning an additional span in the middle.
• In general, homemade mini tractors involve adjustments to certain parts, so you should be prepared for the fact that you will have to turn to a turner to grind some components.
• The bridge is installed into the structure with virtually no changes. It is attached to the frame using four stepladders.
• As wheels you can use similar ones taken from passenger cars.
  

  But there is one important nuance here: the front wheels should be approximately 14 inches, which is the optimal value for the front axle wheels.

• An important stage of work will be the location of the driver's seat. It must be positioned in such a way that the steering wheel does not rest on the driver’s knees, i.e. did not interfere with the free control of the device.

Homemade mini tractors have a very important advantage - they have very good maneuverability. Of course, this assembly method is a little more complicated than the alternatives, but it is definitely worth the effort.

There are quite a lot of models of cultivators of foreign and domestic production from various companies on the Russian market of agricultural products. Cultivator Texas - true European quality at an affordable price.

A garden sprayer allows you to treat the most difficult to reach places, while the active product is securely held on the leaves. By clicking on the link, you will get acquainted with the different types of sprayers for the garden and vegetable garden.

Potato planters mechanize and improve the planting process, making the rows even, planting the tubers at the same distance from each other and at the same depth. Here you will find all the necessary information about potato planters.

In general, in this assembly method, a lot of components are taken from old domestic cars. For example, the steering rack can be borrowed from an old Zhiguli, the same can be said about the drum brake - it can also be taken from a used car.

How to choose a mini tractor base

Before you make mini equipment with your own hands, you need to select a model that will act as a basis. In this case, it is necessary to take into account the following technical characteristics:

• engine power, its torque indicator;
• weight of the future mini tractor;
• type of power unit - gasoline, diesel;
• plow dimensions;
• manufacturer and price.

The area of ​​territory that can be processed with ready-made equipment depends on the power rating of the walk-behind tractor engine. It turns out that the larger the area, the stronger the unit should be. As for the weight of the device, it must correspond to the type of soil. For dense soil, you will need a heavy mini-tractor made by yourself from Neva special equipment. Likewise, and vice versa, with soft soil you need to use a light device so that it does not compact it.

The weight of the machine must correspond to the type of soil - on dense soil you need a heavy tractor, on light, sandy soil you need a lightweight one

When calculating dimensions, the processing depth and ease of use should be taken into account. The best option is a cultivator with adjustable width. There are models on the market equipped with a gasoline or diesel engine. The first option produces minimal noise during operation, has low compression and easy starting with a half turn. The diesel version is economical and highly productive when working over large areas or with difficult soil.

What you need

Before you begin, you should make sure that you have all the necessary parts, materials, and tools.

So, what is required for work:

1. Motoblock. It must be selected taking into account the above recommendations. It is this that will serve as the basis for a homemade mini tractor.

Motoblock Neva - the best option for remodeling

1. Additional wheelset with axle. It is necessary to purchase bearings for the wheels, as well as a steering unit.
2. Metal sheets, pipes and corners. The material is needed to create the body and frame of the structure.
3. Elements for fixing parts and mechanical components. In this case, washers, bolts, nuts, and welding are used.

To carry out the assembly, in addition to the parts, you still need to prepare a number of tools:

• welder;
• drill-driver;
• a set of wrenches of different sizes;
• pliers;
• Bulgarian.

A homemade unit has a number of advantages. First of all, this is the cost. Even if a home craftsman needs to buy a cultivator, he will in any case spend less money. In addition, you can create special equipment of the required size, degree of adhesion to the ground, and performance.

As for the disadvantages, they are that equipment made by hand is much inferior to factory models in terms of reliability. Also, such equipment often requires repair work.

Instructions for assembling a mini tractor from a walk-behind tractor

Those who are interested in how to make a mini tractor from a Neva, Forte walk-behind tractor, or from Zubr equipment need to know that the manufacturer does not really matter; this does not affect the efficiency of the tractor. The main thing is to correctly develop the drawing and construction diagram. Also, the owner of the equipment can use ready-made solutions.

Requirements for a homemade walk-behind tractor

1. Power, taking into account the possible processing area
2. What type of fuel will you use, and, accordingly, your priorities in speed or economy.
3. It is worth considering the cost of the walk-behind tractor, since world-famous and well-known brands will cost an order of magnitude more. And therefore it is better to give preference to a domestic manufacturer.

Among the affordable and optimal quality walk-behind tractors, we can mention the following walk-behind tractors: AGRO, Neva, MTZ, Centaur, Zubr.

The listed models have a number of advantages and they should be chosen based on subjective needs and tasks.

DIY making

The first step is to decide on the options that the mini-tractor will perform. A multi-purpose practice that involves cultivating the soil and transporting goods is generally preferred. For the 2nd option, you will need a cart, which you can make yourself or buy an already working model.

Blueprints

For proper installation of all structural elements, a graphical diagram for displaying working units and blocks of the mechanism is developed. It reflects in detail the areas where the walk-behind tractor shaft merges with the chassis. It is necessary that all elements of the unit are correctly selected. If necessary, they can be processed using turning equipment. We must not forget that the service life and operating parameters of the unit under construction directly depend on the quality of the elements.

When creating a drawing, you need to pay attention to the rotating device. This node comes in 2 types.

• Breaking frame. It is characterized by strength, but the steering rack must be located directly above the unit. An agricultural machine created using this method will have little mobility when turning.
• Tie Rod. Its installation requires more time and additional industrial parts. However, it will be possible to choose the installation location (on the front or rear axle), in addition, the degree of rotation will increase significantly.

Having completed the optimal scheme, you can begin creating the unit.

Mini tractor

Before you start creating a mini-tractor based on a walk-behind tractor, you will need to prepare the necessary tools for the event. Conversion kit contains:

• welder;
• screwdrivers and wrenches;
• electric drill and a set of different drills;
• an angle grinder and a set of discs for working with iron;
• bolts and nuts.

The conversion of a walk-behind tractor into a mini-tractor is carried out in the following sequence.

• A unit on a walk-behind tractor must, of course, be equipped with a strong, durable chassis. It must carry an auxiliary pair of wheels plus a load moved in the tractor, which will exert pressure on the supporting frame. To create a strong frame, the best options would be a corner or steel pipes. Keep in mind that the heavier the frame, the more effective the unit’s traction with the ground will be and the better the soil will be plowed. The thickness of the frame walls does not matter much; the main condition is that they do not bend under the influence of the transported load. You can cut the elements to create a frame using an angle grinder. After this, all the elements are assembled together, first with bolts, and then thoroughly welded. To make the frame stronger and more reliable, equip it with a crossbar.

• Directly after creating the chassis, it can be equipped with an attachment, with which the miniature tractor will be provided with auxiliary devices. Attachments can be mounted both in front and behind the supporting system. If the unit being created is subsequently planned to be used together with a cart, then a towing device must be welded to the rear of its frame.

• At the next stage, the homemade unit is equipped with front wheels. To do this, it is advisable to equip the assembled mini-tractor with 2 already prepared hubs with a brake system pre-installed on them. Then you need to fix the wheels themselves. To do this, take a piece of iron pipe, the diameter of which will fit the front axle. The wheel hubs are then fixed to the pipe. Make a hole in the middle of the pipe that is needed to mount the product to the front of the frame. Install the tie rods and adjust them relative to the frame using a worm gear. After installing the gearbox, install the steering column or rack (if the option with a steering rack is selected). The axle at the rear is installed through press-fit bearing bushings.

The wheels used must have a diameter of no more than 15 inches. Parts of a smaller diameter will cause the front of the unit to “bury”, and larger wheels will seriously reduce the mobility of the mini-tractor.

• At the next stage, you need to equip the unit with a motor from a walk-behind tractor. The best option would be to install the engine in the front part of the structure, since in this way you will increase the balance of the agricultural machine when using it with a loaded cart. To mount the engine, prepare a thorough mounting system. When installing the engine, remember that the splined output shaft (or PTO) must be fixed on the same axis with the pulley located on the rear axle of the mini-tractor. The force on the chassis must be transmitted via a V-belt drive.

Specifications

Engines

One of the main decisions of Salyut engineers is to use not only domestic, but also imported engines from foreign manufacturers (Briggs & Stratton, Honda, Subaru, Lifan, etc.) on a domestically produced frame. Thanks to the use of imported motors, the durability and reliability of the Salyut-5 walk-behind tractor significantly increases, and comfort during operation also improves.

According to reviews from walk-behind tractor owners, the most reliable engines are the American Briggs Stratton and the Japanese Robin Subaru and Honda engines.

The first Salyut 5 models were equipped with Russian-made engines (KaDvi) of the DM series. They were significantly inferior to foreign engines in technical and operational parameters, so in the first half of the 2000s they were completely abandoned.

Gearbox

The pride of the Salyut-5 walk-behind tractor is its gearbox, which has become legendary, the mechanism of which is made entirely of gears. This is the plant’s own development, which was initially manufactured at the main enterprise in Moscow, and then at the facilities of the Omsk Engine-Building Association named after. P. I. Baranova.

The gearbox is made in a single housing, all connections are bolted.

According to Salyut and many users, only a fully gear reducer is the most reliable, durable and maintenance-free for many years

Manufacturers note that during the production of the gear regulator, all technological processes for processing parts are observed, designer supervision and design support of production are carried out. Some factories tried to produce copies of this gearbox, which were significantly inferior to the original - both in service life and in technical and operational qualities

Transmission

On Salyut-5 walk-behind tractors, the transmission consists of a gearbox (gearbox) and a clutch mechanism. Through the V-belt drive and tension roller belts, the drive is driven from the drive pulley to the power take-off pulley (PTO).

The gear shift knob on Salyut-5 is located on the body of the walk-behind tractor, but the company has developed a special gear shift mechanism kit to transfer it to the steering wheel.

The plant has released a special gear shift installation kit, which allows you to move the gear lever to the steering wheel as on the MB Salyut-100.

The speed of movement of the walk-behind tractor and the rotation of the cutters can be adjusted by a 4-groove drive pulley: you need to rotate it relative to the BLOM, unscrew the fastening nut, install the belts in the grooves of a larger diameter and screw the nut back.

The gearbox pulley consists of 3 grooves, the middle one is free for attachments, the other two are for transmission belts.

Mini tractor made from Agro walk-behind tractor

Before you start remaking walk-behind tractors of this brand, you should stock up on the material and necessary tools. To work you will need:

• stainless steel sheets and profiles;
• seat and steering wheel - can be removed from an old car;
• a pair of wheels – their diameter should not exceed 15 '';
• set of fastening elements;
• grinder and electric drill;
• hammer and welding machine.

After preparing everything you need, we advise you to study the diagrams, which will tell you the correct procedure for installing tractor elements.

We also advise you to look at the photos, which will certainly help you in the manufacture of an agricultural implement.

Unlike walk-behind tractors from the manufacturers listed above, Agro brand equipment has one significant drawback, which must be taken into account when converting a walk-behind tractor into a mini tractor. It lies in the fact that the axis of the walk-behind tractor has very weak fracture strength. This kind of fracture will definitely have an effect if you exceed the maximum permissible load on the frame of the mini-tractor. To avoid further malfunction, the minitractor will need to be equipped with wheel gears.

The procedure for assembling the unit is as follows:

1. At the first stage, you need to weld a strong frame for the tractor. To do this, use steel profiles and pipes. Be sure to keep in mind that the heavier the frame made, the better the grip of the minitractor with the ground. At the rear of the supporting structure, weld a towbar, which will be required to couple the trailer to the unit;
2. Then proceed to manufacturing and arranging the chassis of the mini tractor. To do this, you can purchase a pair of ready-made front wheels, as well as hubs equipped with brakes. After purchasing the parts, attach the hubs to a steel pipe, and drill holes in the front of the frame that will be required to mount the hubs on the mini tractor. Next, install the tie rods using a worm gear. Following the rods, secure the steering column and rear axle. When installing the latter, press the bearings into the bushings used for installation. Install a pulley on the rear axle and securely fasten the wheels;
3. After this, install the engine on the front of the frame. We recommend doing this using an additional frame placed on special shock absorbers - this will avoid strong vibrations under high loads on the engine;
4. Next, install the driver’s seat on the mini-tractor, connecting it to the frame through springs - thanks to them, working with the mini-tractor will be much more convenient.

If desired, a compact tractor made by yourself can be equipped with a canopy that will protect you from rain and sun. To make it, 4 steel pipes need to be welded to the frame next to the seat and steering column, to which a steel sheet must be secured by spot welding. As a result, you will receive a reliable unit for your garden that will quickly cope with all the tasks assigned to it.

Alternative options

For conversion into a mini tractor, not only walk-behind tractors produced by MTZ are used, but also products from other brands. Each model has its own characteristics, but in general the assembly algorithm differs little.

“Neva”, “Centaur”, “Bison”, “Agro”

Motoblocks "Neva" are equipped with Subaru engines. The machines have a lot of power and are quite heavy, so converting them into a mini tractor simplifies control. A coupling mechanism is supplied with the design of this brand. It is intended for various attachments, thus solving the problem of connecting it to the machine. Motoblocks "Centaur" are equipped with a diesel engine. It is mounted in the front of the frame, which is traditional for such equipment. Meanwhile, torque is transmitted to the rear pair of wheels through the use of a belt or gear drive.

Motoblocks of various capacities are produced under the Zubr brand. To reconstruct them into a mini tractor, it is recommended to use heavy models. They are equipped with a liquid cooling system, which makes it possible to work in adverse weather. To build a control system, you can use a VAZ gearbox, and for the stopping system, mechanical belt-type brakes are used.

When producing a mini tractor from Agro walk-behind tractors, remember one important feature. Their standard axle is characterized by low fracture strength, thereby increasing the risk of destruction during operation

To avoid this, you need to strengthen it. For this purpose, modernized wheel gearboxes designed for VAZ or LuAZ SUVs are used.

"Oka", "Salyut", "Cascade"

Mini tractors made from the Oka walk-behind tractor are equipped with a reversible gearbox, including two speeds. When converted, they are equipped with a frame and all-wheel drive, making all wheels driving. The engine is mounted at the front and has a factory hood to protect it. The transfer case is located in the rear. The drive of both axles with chain gearboxes is also located there.

Engines from leading brands are installed in Salyut walk-behind tractors. Their power usually varies between 6–7.5 l/s. The gearbox is equipped with two main gears and an additional reduction gear. The kinematic scheme involves the use of two V-belts, due to which:

• the quality of torque transmission improves;
• the risk of dangerous slippage that can occur under active loads is reduced;
• the useful life of the machine increases.

If you make a mini tractor from a Salyut walk-behind tractor, it is advisable to increase the wheel track of the rear and front axles to 1200 mm. This manipulation will increase the stability of the vehicle. For the drive wheels, and there can be either two or all 4 of them, only standard tires are used.

When making a mini tractor yourself from “Cascade” walk-behind tractors, you can use “stockings” from old rear-wheel drive “Muscovites” or “Zhiguli” in the design of its rear axle. During operation, the “stockings” are shortened, which optimizes the wheel track parameters. To build a control system, it is convenient to use a rotating beam from PAZ buses, while the hubs and gearboxes are taken from Zhiguli cars.
