How to make a homemade mini-tractor with a breaking frame do it yourself

For small farms mini-tractor - this is the best option when choosing processing equipment. Prices for new factory equipment are high, and the option with second-hand is not always available. In this case, help yourself collected samples. Self-made mini-tractors with a breaking frame are very popular with farmers.

Mini tractor breaking point: what is it

Tractor tipping frame - these are two semi-frames articulated by a movable hinge mechanism. This design has several significant advantages:

• improved balancing and consequently increased patency;
• small turning radius, such a tractor can literally turn around itself, which is important in small areas;
• good power density and, accordingly, high efficiency.

Usually, such mechanisms are equipped with a drive for all 4 wheels, which increases their throughput and stability. Assemble tractor do it yourself with a breaking frame more difficult than with a solid, but the advantages of this model justify the effort expended.

Features of the collection device

Assembling such a complex device as a tractor will require considerable time and financial investments.

In addition to the acquisition of parts and components of the unit, you need to consider that you will need some tools. If you do not have them, you can contact your friends for help or use the rental service.

What tools are needed

Since many parts will have to be customized to each other, and some even to be made independently, many tools will be needed:

• welding machine;

• lathe;

• metal cutter of any type;

• installation tool (screwdrivers, wrenches).

Required materials for construction

The device consists of multiple nodes, some can be taken entirely from other equipment, some will have to be redone:

• composite frame;
• engine;
• running gear, including suspension, axles and wheels;
• assembly with brake discs;
• steering mechanism;
• seat;
• attachment mechanism.

Designing a homemade tractor (drawings)

Strong recommendation: Do not try to assemble such a complex device as a mini-tractor, without having at hand sketches and drawings.

In the process of assembling it is necessary to articulate and adjust the mass of parts, and it is very difficult to do this without having a general picture and detailing. If you do not have design skills, refer to friends who can help you in such a difficult task, or to collective intelligence: on the Internet you can find a lot of options that will suit you.

How to make a tractor with a breaking frame do it yourself

Tractor assembly begins with the manufacture of the frame, the phased installation of the remaining components on the base, the installation of the hydraulic system and electrical wiring. Let's take a closer look at each stage

Frame and body

Frame components weld from metal channels (depending on the planned power of the unit use channel from No. 5 to No. 9) and connect them together by a hinge mechanism (for these purposes often use cardan shafts from trucks). On the rear frame if necessary, mount a reinforced vertical rack for attachments.

For the body, which does not account for such loads as the frame, you can use less expensive material. Frame, for example, can be welded from metal bar.

From above, the frame and its place of articulation will then be closed with a metal sheet.

Steering and seat

Steering it is strongly recommended to equip with a hydraulic actuator: drive a tractor on viscous earthin the field of one muscular strength will be very hard. The hydraulic system can be removed from any other agricultural equipment. Since the suspension on the tractor is tough, the seat should be made soft and, perhaps, torsion - it will have to spend quite a lot of time.

Engine

Ulyanovsk engines (UD-2, UD-4) are often used for home-made vehicles, but there are a lot of alternatives, ranging from the above-described variant with a car to engines from motorcycles, walking blocks and forklift trucks.

You will also need to set the gear ratio so that at a speed of about 4 km / h, the engine speed is about 2000 min-1. Such indicators are optimal for arable work.

Wheels

Bridges (both rear and front) are taken from cars or trucks, before shortening the half-line up to the required length. You can install an independent suspension on the front axle (for example, from Zaporozhets), it is better to leave the rear axle rigid. Wheels choose depending on the primary tasks of the unit. If his main work will take place in the field and on rough terrain, it is better to put wheels with a diameter of 18-24 inches. If, in general, it will be used for transportation tasks, then smaller wheels will fit - from 13 to 16 inches.

Additional equipment for tractor 4x4 with breaking frame

For productive work The mini-tractor must be equipped with a power take-off shaft (PTO) - attached and attached implements (plows, mowers, headers) are connected to it. PTO can be taken from an old tractor or decommissioned military equipment. If you intend to use a mini-tractor in the winter, you can equip it with a cabin. Otherwise enough tarpaulin canopy. For the convenience of working in the dark, install headlights and dimensions.

Self-made mini-tractor with a 4x4 drive and with a breaking frame are indispensable helpers on farmers' fields. It is possible to assemble such a unit during the winter months when there is no field work.

BUT cheap assembly and maintenance makes it practically the only choice for small farms.
