Mini tractor homemade 4x4 in work. Make a homemade minitractor with a broken frame with your own hands. What to make a frame

To assemble a self-made minitractor 4x4 fracture, you will need to draw up the scheme, learn construction features Technique. The need for such an aggregate occurs when it is necessary to treat land, plant or remove the harvest.

Step-by-step instruction

The classic of agricultural machinery is made with their own hands using a welding machine, disk plate, drill. The assembly of the mechanism begins with the manufacture of the frame. It consists of a spar, front and rear traverse. The spar is made from the ranger of 10 sizes or the square shape tube 80x80 mm. On the traverse you need to use 16 size. Any engine will suit the 4x4 minitractor. The most suitable option is 40 hp The grip will be required from GAZ 52, and the gearbox is from GAZ -53.

To connect the basket and force aggregate, have to do new flywheel. The bridge applies any size and is inserted into the mechanism. Cardan shaft make up from different cars. In the homemade tractor 4x4 bridge in the front constructs independently. For good depreciation, tires are 18 inches. On the front axle Suitable discs by 14 inches. If the wheels are smaller, the 4x4 minitractor will fall into the ground. Otherwise, the technique will be hardly managed.

To reduce the load on the chassis, use tires with good soils.

During the manufacture of a mini tractor for household It is necessary to use cardans of the main transfer from trucks.

In all minitractors 4x4, the fracture is installed with their own hands the gearbox closer to the driver and fixes on the frame. For pedal control homemade, it is recommended to put a hydraulic drum brake. And the rack of the steering wheel, and the pedal control fractures are suitable from the VAZ machine.

Assembling machinery

The components of the tractor are fastened with bolts or welding. Sometimes possible combined fastening of parts. It is important to position the seat dismantled from the passenger car. The next stage of assembly of equipment is the installation of a power unit. To touch the motor on the frame to well, you need to use a special plate with grooves. Then it will be necessary to pave electrical and mechanical system Control. So that such work was performed qualitatively, the electrical system of factory mini tractors is studied. Next, cubs, taking into account their wishes.

The next step is to arrange the body and its combination with the engine unit. A small trailer from the passenger car can serve the body. If the whole process of breaking briefly, we get a simple algorithm: a motoblock is located on the frame, a drum braking system is installed and steering Reika from Zhiguli.

Motoblock take any. If we take the motoblock "Neva", it is more expedient to choose with the hitch. Then the mini tractor will carry loads and trailers. Another suitable motoblock is a Diesel Block "Centaur". To determine which motoblock to choose, you need to deal with the target destination of the mini-tractor. The tractor with a broken frame 4x 4 has a basic advantage - maneuverability.

Conclusion on the topic

If necessary, you can make a haymaker, cutter, bucket. The main advantage of the tractor with a broken frame is maneuverability. Its assembly is simple, so such an agricultural unit can make any dachane, which disassembles the technique. The cost of the self-made car will be relatively lower than the price of the Pskov factory analogue.

MT 244 Caliber Minitractor can be operated in all conditions and full off-road. Air suspension Consists of a receiver, an updated TC control valve, compressor. Minitractor Calibr MT 244 can be stored in the garage, and due to the presence of reinforced hinged equipment Easy fixation of various devices is ensured.

The tractor is not necessary to buy - it can be collected with his own hands. There is an embodiment with a monolithic frame, which is easier, or with a broken - it will have to be tinted with it, but the car turns out a maneuverable one. The homemade mini tractor fracture 4x4 is completely constructed from elements of old cars and equipment.

The name "Refractory" Tractor received due to the frame, which consists of two parts. Before starting the assembly, you need to have a circuit with the size of nodes so that all the elements approached the dimensions.

4x4 tractor with a turning point with their own hands

This process can be described by the general scheme, but in practice, almost every self-taper collector contributes its own adjustments to the design.

For the assembly of a mini-tractor, the fractures usually adhere to the following requirements:

• The frame has a system of spars of 3-steps. For the front earning sewners number 10. The third stage is made from a pipe with a cut of 8 to 8 cm.
• The front traverse can be made from Schweller No. 12, for the rear, it is best to use №16.
• The crossbars are built on the same system.
• The engine is selected according to suitable characteristics - size, power, fastening type.
• Most often choose a 4-cylinder diesel engine for 40 liters. from.
• Liquid cooling allows the technique to work all day without overheating.
• The next step is to install the power take-off shaft, checkpoint, dispensing box. The details of the old gas-53 truck are ideal.

To connect the motor and the clutch, the remission of the flywheel is required - pruning its back and pulling the new span. Modernization of the casing consists in fitting under the desired size.

The cardan shaft and the rear axle are suitable from any car, you don't need to change anything in it.

How to install a wheelbase with your own hands?

Here the main thing is to choose the correct diameter of the wheels. For a mini tractor with a turning point, it can be taken with passenger carsmobileif the diameter of the disks of at least 14 inches. Too small wheels will be linked to the ground, and with large - it is difficult to manage technician. It is possible to facilitate the use of the tractor by installing the hydraulic system. It is completely removed from any decomposed agricultural machinery.

• The front axle is easy to build from the pipe by installing bearings on it. Another option is to take from the other, unnecessary technology.
• Tires need to choose with a deep tread pattern - it increases the tractor maneuverability.
• Good depreciation gives tires by 18 inches.

Rear wheels are installed on the hubs of the bridge simple way: The center of the disk with the mounting holes is cut, and the same part from ZIL-130 is welded to this place.

How to install steering?

For the assembly of a mini tractor, anyone comes up with any steeringtaken from a passenger car. The most successful will be the option with the hydraulic system - it will improve the handling of the tractor.

Also need an oil pump - it starts using the engine. Wheels basically best connect through a gearbox.

An important element of the system is a drum hydromechanical brake. It connects with a pedal.

After all parts of the design are collected, issued workplace Operator. To do this, the seat adjustment seat is installed. You can build a canopy with your own hands, consolidating it on 4 welded racks.

To ensure safety, the engine and all internal elements are hiding under the steel casing - it is usually fused from the galvanized steel sheet. To work in the dark, the tractor is equipped with a headlamp and a battery for it.

The minitractor is an indispensable agricultural machinery for land processing, planting seeds and harvest assembly. This technique is especially in demand in the village, among the owners of large household plots. The cost of minitractors in the factory execution is sufficiently high. Even new Chinese production techniques are sometimes not for the pocket. Therefore, more and more domestic masters are trying to make a mini tractor on their own using braid materials.

If you decide to collect a minitractor with your own hands, then first you need to pick up a power unit to it. As the latter often use zid engine. This is a four-stroke unit with a volume of 0.52 liters. and with a capacity of 4.5 l / s, which is quite suitable for processing 2-3 hectares of the Earth. The engine is characterized by ease of maintenance, so it is often installed on various homemade techniques, besides, it is easy to buy it on the Internet.

Another option for homemade is . This is a two-cylinder unit having a power of about 12 l / s and a volume of 0.42 liters. Although this type Motors have long been removed from production, on the Internet there are a large number of offers for the sale of this unit. It can be bought for approximately 5,000 - 8,000 rubles.

Often, during the manufacture of self-made masters, motors from cars are used. For example, you can find minitractors with an engine from Oka.

This engine has a power of 29.3 l / s and a volume of 0.649 liters. In essence, this is a Vaza engine (VAZ 21083), only in a lightweight version, since it has 2 times less weight. The distinctive feature of the engine from the eye is a small consumption of gasoline and high efficiency.

More expensive option is engine from "Zhiguli". Motors of the VAZ car line have the engine power from 59 l / s (VAZ 2101) and above. A tractor with a VAZ engine is a fairly powerful unit that is able to cope with almost any agricultural work.

Motoroblock owners make a miniflower for household is the easiest way, since this unit already has all the necessary control nodes. It remains only to make a suitable frame, and the tractor is ready.

What to make a frame

Assembly of a minitractor always begins with framework. The minitractor frame performs the role of the base on which all the nodes and parts of this unit are fixed. The frame should be strong enough and at the same time not very heavy. Usually it is made from metal Corner, Profile Pipe or Schwell. Connect the parts by welding. Frame can be solid or consisting of two parts.

Whole frame Make the easiest way. It is enough to weld a rectangle from a chapellery or corner. The size of the frame is calculated on the basis of the engine size, gearbox and other nodes.

Also among the owners of household plots are greatly popular with minitractor 4x4. This is all-wheel drive minitractor with breaking frame. The word "all-wheel drive" means that the aggregate leads are both bridges, front and rear. An example of such a frame made from Schweller No. 10 is shown in the following photo.

Knot Far Rama most often make from cardanian Vala Car, for example, from GAZ-52.

The main advantage of the self-made tractor with a broken frame is a small radius of the reversal of the unit. Due to the high maneuverability, the minitractor is successfully used in small areas, where the turn of a minitractor with a solid frame will be difficult.

Below are the drawings of the frame connected by the hinge.

What makes the running

To assemble a minitractor, you need to prepare it running part. It includes wheels, front and rear axles, transmission elements.

When choosing wheels for a minitractor It should be taken into account the purpose of using the latter. If the unit is constructed for a transfer and dragging of goods, then the diameter of the disks in 16 inches will be enough. When using a tractor in the field, it is better to use more massive wheels having discs with a diameter of 18 to 24 inches.

If the leading bridge in your tractor will be only the rear, then front beam is manufactured quite simple.

To make a homemade front axle, as well as its rear analog for all-wheel drive aggregate, It will be necessary to take 2 identical nodes of the chassis, for example, from a VAZ or Muscovite car, and shorten them. How to shorten the bridge from the car VAZ, you can learn from this video.

Important! Bridges must have the same gearboxes, with the same gear ratio. Otherwise, the front and rear wheels when the tractor moves will rotate at different speeds.

As bridges already have a built-in mechanism for transmitting rotational motion on the axis of the wheels, the homemade gearbox will not need to be manufactured.

Pluses of hydraulics installation

Hydraulics on a minitractor is established to ensure that it works to some of its mechanisms and facilitate the management of this unit. The unit with a hydraulic installed has its advantages.

1. The car becomes easy-to-control. The steering wheel can be twisted, virtually no effort, one hand.
2. Hydraulics makes it possible to apply various attachments.
3. The use of hydraulics allows you to upgrade brake system. Thanks to the hydraulic cylinders installed on the unit, the braking of the unit occurs instantly.

It is possible to make hydraulics on a minitractor if you have to purchase a ready-made system in the store in advance or use the details from the old agricultural machinery.

Important! When installing hydraulics on a minitractor, it should be borne in mind that some of the engine power goes to maintain this node. Therefore, for tractors with low-power engines, the installation of hydraulics will not bring any benefit.

What is needed for what

Power takeoff shaft (VOM) is designed to bring in the movement of various agricultural mechanisms connected to a minitractor, for example, various cutters for the processing of land, potatoes, mowers, snowbursters, etc.

In may be like dependent and independent. In the first case, the shaft is driven by a transmission transmitting rotational movement to the wheels. Once the wheels stop, it stops rotating. Independent POW gets rotation from crankshaft Engine. Therefore, the higher the engine turnover, the faster the shaft rotates.

In addition, there are tractors with Synchronous type. The speed of rotation of the synchronous shaft directly depends on the gear ratio of the transmission of the moving tractor. Synchronization of movement and rotation is required when an aggregate with sowing equipment is operating.

Production of three-point hitch

The mood is used for connections to the tractor additional equipment , for example, a plow.

The mood must be movable both in the horizontal plane and in the vertical. In the first case, mobility helps to reduce the departure of the nozzle when piring. The vertical movement of the suspension is required to lower the equipment into the working condition or lifting it to the transport position.

The jacket on the minitractor is made from various parts taken from the old agricultural machinery. Make a description of how to make a three-point hitch at home is quite difficult. Therefore, it will be more correct to use the following videos, which indicates the dimensions of all parts of the device.

Selection and installation of brakes and clutch

Brakes need to be installed on the back wheel pair. The easiest to take finished blocks from car UAZ. Brake pads need to be installed on the wheels of the wheels, and the control is displayed on the pedal or lever installed inside the cab.

To set the grip on the homemade minitractor, you can also use ready option from any car. For example, you can use bellen grip from Muscovite or UAZ.

The clutch unit is attached to the gearbox, also taken from any car. How the clutch is installed, you can see in this video.

Installation of the steering

It is quite difficult to produce the steering mechanism yourself quite difficult, and in principle it makes no sense, since all parts can be taken from any passenger car.

When installing the steering mechanism, the steering shaft with the gear is connected to the steering bumps that are available on swivel fistsinstalled on the front beam (the manufacture of the beam was considered above).

How to make a cabin for a minitractor

If in a summer period, it is possible to work on a minitractor without a cabin, then with the onset of the autumn-winter period, the use of the unit becomes quite uncomfortable or at all impossible. Therefore, the craftsmen are trying to collect tractors with cabins to use this technique all year round.

Cabin for homemade technology is manufactured from sheet steel According to a predetermined drawing. As the basis of calculations, you can take the cockpit from tractor MTZ. The following photo shows the drawing, based on which, you can make the cabin independently.

Tip! If the sizes of the cabin existing on the drawing are not suitable for the size of your minitractor, they must be changed. But the main thing is that you need to consider when correction of sizes is the size windshield and cab altitude. Its ceiling should be above the head of a person sitting in a 25 cm cabin.

The cab is manufactured as follows.

In general, it is better to understand how the mini tractor is made with their own hands, you can see this video, a kind of allowance for beginners.

Crawler tractor making nuances

Homemade tracked minitractor is a technique, the main feature of which is high maneuverability and good permeability. Also, the tractor on caterpillars creates minimal pressure on the soil, which cannot be said about its wheel analogue.

To make a minitractor on caterpillarThe following design elements will be needed.

1. Frame. It is made from the profile pipe or chapellor.
2. Engine. For a caterpillar minitractor, it is better to use a diesel engine.
3. Main bridge. As with the manufacture of a wheel tractor, a ready-made bridge from an old car can also be used for the caterpillar unit, which should be shortened.
4. Transmission. The ideal option will be a box from GAZ-53.
5. Clutch. Suitable clutch block from GAZ-52.
6. Caterpillars They are made of tires from wheels of large-sized equipment, for example, from the tractor.

For the manufacture of caterpillars You need to take 2 tires from the tractor and cut the side parts on them. Then these tires are dressed on the wheels mounted on the frame, as shown in the next photo.

So that the tractor can turnOn the back bridge you need to install differential, which will turn off the right or left wheel from the drive. Also, each wheel should be equipped with a brake, controlled separately. When you click on the brake pedal and switching the differential, one wheel of the leading bridge stops, and the opposite continues to rotate. Due to this, the tractor unfolds in the right direction.

In small farms with the help of a mini tractor, you can break the soil, collect the crop of agricultural curtulines, perform other works. This technique is quite expensive.. Therefore, many farmers make mini tractor homemade with a broken frame and details from old cars.

What it is

Such devices have two semiramps that are connected by moving hinges. It has such advantages:

• good balancing;
• excellent permeability;
• small reversal radius;
• high power.

These designs are driven by 4 wheels, which improves stability. Homemade tractor A broken frame works as a mini-tractor based on a motoblock. Tractors are factory manufacture, homemade or converted with tools. The manufacture of the tractor is complex, but interesting, which requires engineering knowledge and skills to assemble and design moving equipment.

There are several build options. But there is an optimal way of installation that is suitable even for novice designers. In the frame, all elements are distributed as balanced as possible. It consists of two seats. How to make it nodes, you need to know before starting work.

In addition to the frame, you will need to make a steering system, install and weld the motor, think over and create a transmission and chassis. The engine must be diesel. Its power is selected in accordance with the desired productivity of the tractor. Bridges can be taken from the old car. The wheels put a diameter of 20 inches so that it is possible to increase the passability of complex relief and uneven rocky soil.

Blueprints

Before embarking on the design, it is necessary to perform drawings and make calculations of the main designations. In the drawings, you should specify the dimensions of all parts and items and mark the places of their welding.

Tools for design

For the manufacture of homemakes, nodes and parts are needed from the used technique: Motoroblocks, cars and other devices. Metal sheets, profile steel structures: chawllers, corners, screws, bolts, different kinds Mounts, screwdriver, screwdriver, construction level, tools and minor parts.
