Breakaway mini tractors (with a breaking frame) greatly facilitate the cultivation of the land. They are compact, so they can work in small areas of land due to their small turning radius. Such units can be easily made at home.

What is a breaking frame

The breaking (articulated) frame is nothing more than 2 large half frames. They are connected using a swivel joint. The technique has a high degree of maneuverability. The advantages of self-made breakable all-wheel drive mini-tractors:

  • a significant reduction in the turning radius (while the unit is able to turn full 360 degrees, being in one place);
  • the tractor has good maneuverability in highly swampy areas with variable relief;
  • the moving frame changes the balance pattern of the machine, which makes it possible to provide reliable, good traction with the soil;
  • this tractor has an even load distribution so it delivers maximum power.

In terms of its characteristics, equipment with a breaking frame is significantly superior to light gardening equipment and is in no way inferior to heavy factory tractors. Typically this unit is 4-wheel drive (all-wheel drive). This increases the cross-country ability and stability of the tractors.

Features of collecting device

Assembling a tractor with a break frame will require a significant investment of money and time. It should be borne in mind that some tool may not be at hand, and it can take a long time to find it. However, a do-it-yourself fracture mini-tractor is cheap, especially when all the necessary equipment is at hand. Even the comparative difficulty of creating a fracture mini-tractor is compensated by good work results.

What tools will be needed

To make a model of a breakable mini-tractor 4x4, you will need the following tools:

  • welding machine;
  • lathe;
  • metal cutter;
  • screwdrivers, wrenches and other assembly tools.

Materials for construction

The device under development consists of several units. Some tools are taken from other techniques without additional alteration, some require some revision. Necessary materials:

  • frame;
  • engine (can be from the "Neva" walk-behind tractor);
  • loader, handouts;
  • chassis (it includes wheels, axles and suspension);
  • an assembly that includes brake discs;
  • asterisks;
  • steering;
  • seat;
  • the mechanism to which the attachment is attached.

Note! The ideal option would be to purchase an old passenger car (Zhiguli, Niva, Oka), from which all the necessary parts can be taken.

Designing a homemade tractor

There is no need to assemble such a complex device without detailed and understandable drawings. In the process of work, you need to fit and connect a large number of parts, without a drawing it is almost impossible to do this. The choice of drawings is rich, with the help of special literature you can create an original version of a motor cultivator.

Every farmer, gardener has different design abilities.If they are not there, then you can contact your friends who will certainly help in this difficult and useful matter.

DIY tractor

To assemble a mini tractor with your own hands with an engine from a 4x4 walk-behind tractor, you need to follow the sequence of actions. You always need to start with the base, then move on to the details.

Frame and body

To assemble the structure, you need to weld 2 frames. The required dimensions of the front frame are 90x36 cm, and the rear frame is 60x36 cm. Channels with numbers from 5 to 9 are used. Self-made units made using such a profile are resistant to increased loads. If there are no increased requirements for the rigidity of the structure produced, it is allowed to use a softer profile.

Important! The connection between the two structures is made at an inclination of 45 degrees. If you take too thick metal for the frame, then the tractor will be heavy and uncomfortable.

The front frame has 2 square tubes. They will carry a stretcher. Several sites should be welded for the installation of other nodes. Their number depends on the general structure of the tractor.

A vertical metal rack is installed on the rear frame. It intensifies at the sides. A metal plate is attached to the back of the half-frame. It is necessary for hitching; without it, the tractor will not function normally with additional equipment.

Important! The plate and corners are made of metal, the thickness of which is not less than 12 mm.

The semi-frames are connected to each other using a gimbal mechanism. Cardan is a steel forks with a hinge. Details for the construction of the cardan mechanism can be taken from Kamaz. If the farmer has a mini tractor model from UAZ, a fracture with his own hands will have similar characteristics.

Correctly installed half-frames should move easily horizontally and vertically. From above, the frame and the joint are covered with a sheet of metal.

Steering and seat

The steering column is bolted to the front frame plate. In order to turn the steering wheel in a homemade product exactly repeating the movements of the tractor, you need to insert the worm gear in the opposite position.

 

Steering and seat

A mini-tractor with a break frame is interesting in that the steering wheel is in the front of the frame, while the driver's seat is in the rear. If you do not change the direction of the worm gear, it will be very difficult to operate the tractor.

The hydraulic pump and oil tank are located in close proximity to the power plant. Hydraulic cylinders are a must because they make it much easier to operate the mini tractor during intensive field work.

Additional accessories that are inserted to improve performance:

  • front hitch for cleaning snow, debris;
  • power cylinder for changing the location of attachments;
  • resora for the driver's seat;
  • sheathing elements.

Engine

An engine is installed on this tractor, from any passenger car. The motor can be subframe mounted and secured with bolts.

Important! Additional cooling equipment must be installed on the engine. This is due to the fact that the motor from a passenger car cannot cope with a large load. Cooling installation is especially important in regions with very warm summers.

When installing the motor, the required gear ratio must be calculated. If the tractor speed is between 3 and 5 km / h, the speed should not be less than 1800 revolutions per minute. The pressure per share varies from 190 to 300 per square centimeter.

Note! The recommended values ​​must not be exceeded, otherwise the plowing process will be ineffective.

Various engines can be retrofitted, depending on the original idea and the tasks to be carried out with the mini-tractor.

Some mini tractors may have 1 or 2 cylinder diesel engines. In this case, a 4x4 car will require some increase in the gear ratio. Motors of the UD-2 and TsD-4 types are often used.They handle the workload perfectly and lend themselves to re-arrangement. MT-9 motors have a large margin of safety and durability.

Wheels

The frame of the mini-tractor is mounted on wheels. There are no general guidelines on what wheel sizes should be. For transportation of goods, you need to choose wheels with a diameter of 13 to 16. For field work, you should choose wheels with a diameter of 18 to 24.

 

Wheels

If you choose undersized wheels, the mini-tractor will not work properly and fall into the ground. If you pick up wheels with a large size, then the driver will need to spend a lot of energy during field work.

Note. Tires must provide good traction. This will increase maneuverability and reduce the load on the chassis.

Optional equipment

For high-quality and productive work, homemade 4x4 mini tractors must have a power take-off shaft. All other devices are attached to it, such as mowers, plows, headers and other equipment. The power take-off shaft can be "borrowed" from old tractor equipment.

A cab for such a mini-tractor is needed if it is intended to be used in winter. Otherwise, it will be enough to install a simple tarpaulin canopy.

Interesting. For safe work in the country at night, headlights and side lights should be installed.

A 4x4 do-it-yourself mini tractor with a breakable frame is an excellent assistant for processing farmland with a large area. Despite the fact that it will take a long time to collect, it will bring excellent results. Low cost of assembly makes mini tractors with a break frame the best companions for small farms.
