The walk-behind tractor has become an indispensable assistant in the household, since it allows the user to spend less of his own energy on plowing the land. In addition, this technique is used as a small-sized vehicle, which requires an additional hitch.

What it is?

A tow hitch is understood as a hitch or towing equipment. They are necessary in order to ensure reliable fastening between the walk-behind tractor and the trailer.

The towbar must guarantee the user safety, reliability, respectively, its design is carefully thought out, and special requirements are imposed on the material.

It is extremely important to choose a suitable hitch for a walk-behind tractor, since a lot depends on its quality.

It happens:

  • single or double;
  • with a reinforced structure;
  • with the possibility of adjustment;
  • universal option.

If at the time of operation different hinges are used, then it is better to purchase a single or double hitch. When additional equipment is large or you need to transport a large load, then it's time to use reinforced.

It differs from the previous one in greater thickness and length. Thanks to the design, the plow or cutter can sink deeper into the ground.

Adjustable allows the user to set the required shaft angle. As a result, the attachment is set to the required level, and the work efficiency increases accordingly.

Universal The hitch is used everywhere and can be rearranged to different models. Due to it, the user has the opportunity to adjust the angle at which the attachment is installed. The bolt mechanism plays the main role.

It is for the very reason that such a hitch is used when attaching hillers and plows, it can be either double or triple, which means that it is not forbidden to connect several working elements at the same time.

The most commonly used is a U-shaped knot, which can be made both independently and purchased ready-made. There is also a hitch for the APM adapter on sale, which is necessary when working with a hiller or plow.

It is used on walk-behind tractors:

  • "Neva";
  • "Oka";
  • "Centaur 1080D";
  • MTZ;
  • "MB";
  • "Cascade".

The product is attached to the rear or front adapter, and then additional equipment such as a plow, potato digger is attached. The design of the product is thought out in such a way that a reliable fastening can be ensured through the use of three bolts. When the walk-behind tractor tilts during operation, the plow remains perpendicular to the ground.

When using some couplings, the user has the ability to adjust the height and change the angle of inclination in the desired plane.

For example, in the horizontal plane, the maximum allowable angle is + -20 degrees, in the vertical plane it is 7 degrees more. There is also a version of the hitch for motoblocks on the market - MK, used for the "Mole" series plow and the "OH-2" type hiller. It is used exclusively only in this version and in no other way, that is, it will not be suitable for other attachments.

Specifications

At the couplings "Zirka" in the shortened version, the height of the inner sleeve or the diameter of the hole ranges from 2 to 9.4 centimeters. At the same time, the weight of the structure is 4.6 kilograms. The size of the frame strip is 315 mm.

Such a product is distinguished by the adjustment angle and the presence of a rotary mechanism, due to which the plow, regardless of the conditions, works the soil strictly horizontally, even if the walk-behind tractor is displaced. The hitch is widely used when it is necessary to correct the operation of the attachment or when plowing an uneven surface.

There is an extended version of the described model on the market. The weight of the structure has increased to 7.5 kg, the inner diameter is 210 mm, and the bushing has a height of 94 mm. The dimensions of the frame strip are also larger - 520 mm.

The product is used so in cases when it is required to adjust the operation of attachments.

The design used a swivel-type clamp. The plow always runs at right angles and all thanks to the bolt connection, while the position of the equipment does not matter.

There is also a bolt clamp on universal couplings, but they are attached to the equipment using a special adapter. The width can reach 0.9 meters, the maximum weight is 6.6 kg.

If we consider a triple model, then it is installed on the walk-behind tractor using the front part on the swivel unit. This part is bought separately, since it is not supplied with any walk-behind tractor. The width of the described hitch is 900 mm. The mounting plate has a width of 80 mm and a length of 120 mm. The weight of the structure is 7.3 kg.

If it is supposed to use a walk-behind tractor as a snow blower, then it is better not to find a U-shaped hitch.

Installation

There is nothing difficult in installing the hitch on the walk-behind tractor. Pins will need to be screwed onto the brackets, for which M14 bolts are used. If necessary, it is allowed to attach additional equipment, but before that it is necessary to secure the axle from the hitch. The outer hole of the hitch is taken as a reference point, where the axle is filled.

At the second stage, they begin to tighten the bolts, but this should be done in such a way that the holes on the body and the rack coincide. After the assembly is fastened with M12 bolts. As time shows, the used scheme is not only easy to learn, but also effective. Even the adapter will be strictly controlled by the user.

Customization and use

If the user did everything correctly and the attachment is correctly attached to the walk-behind tractor through the hitch, then it will be easy to set it up. It is advisable to drive a walk-behind tractor for the first few meters and check the quality of the hitch.

The main thing that you need to pay attention to is that there should be no jamming or distortions during the operation of the equipment. If problems arise, the unit is stopped and the bolts are tightened.

Can you do it yourself?

Some users who are not used to additional costs prefer to make such parts on their own. This can be done if you devote a lot of time to the drawing and carefully calculate everything.

In this case, experts advise:

  • choose a universal hitch model as an example for manufacturing, since 90% of motoblocks allow you to use it;
  • take into account the level of pressure exerted on the part, for this reason, use only high quality material, preferably large sheet steel;
  • keep a U-shaped coupling as a basis, for the manufacture of which a square channel with dimensions of 4 * 4 cm is suitable;
  • first make a pin that will be used in the hitch, and then drill holes in the channel for its diameter;
  • use a bracket, the longest part of which points downwards, but it must not reach the ground.

Tips for choosing

When buying a ready-made coupler, the user should take into account:

  • design features of the equipment on which it is supposed to use additional attachments;
  • take into account the type of attachment;
  • the value of the possible load.

The best option is a universal hitch to the walk-behind tractor trolley, which will avoid many problems at the stage of equipment operation.
