Large equipment is inconvenient for processing small gardens, so the mini-tractors that appeared on sale immediately began to be in great demand. In order for the unit to perform its tasks, it needs attachments. The main tool for cultivating the land is a plow for a mini-tractor, which, according to the principle of operation, is divided into three varieties.
Plows for a mini-tractor
There are many varieties of plows. According to the principle of operation, they can be divided into three groups.
Disk
By the name of the equipment it is already clear that the design has a cutting part in the form of disks. It is intended for processing heavy soil, swampy soil, as well as virgin lands. The cutting discs rotate on bearings during operation, so they easily interrupt even a large number of roots in the ground.
As an example, consider the model 1LYQ-422. The equipment drives the power take-off shaft of a mini-tractor, rotating at a speed of 540–720 rpm. The plow is characterized by a plowing width of 88 cm, a depth of up to 24 cm. The frame is equipped with four discs. If, during plowing, the cutting element hits a stone, it does not deform, but simply rolls over the barrier.
In another way, this equipment is called a reversible plow for a mini-tractor because of the principle of operation. After finishing cutting the furrow, the operator does not turn the mini-tractor, but the plow. This is where the name came from. However, according to the device of the cutting part, it will be true when the plow is called a share-dump plow. It comes in single and double sided. The working element here is a plowshare made in the form of a wedge. While moving, it cuts the soil, turns it over and crushes it. The depth of plowing with a single and 2-furrow plow is regulated by a support wheel.
As an example of a double-furrow plow for a mini tractor, let’s take the R-101 model. The equipment weighs about 92 kg. You can use a 2-furrow plow if the mini-tractor has a rear hitch. The support wheel adjusts the plowing depth. For this 2-body model, it is 20–25 cm.
Rotary
A modern, but complex design is a rotary plow for a mini-tractor, consisting of a set of working elements mounted on a movable shaft. The equipment is characterized by ease of use. During tillage, the operator does not have to drive the tractor straight along the line. Rotary type equipment is usually used in preparing the soil for planting root crops.
Depending on the design of the rotor, the rotary plow is divided into 4 types:
- Drum-type models are equipped with rigid or spring pushers. There are also combined designs.
- Paddle models are a rotating disk. 1 or 2 pairs of blades are fixed on it.
- Blade models differ only in the working element. Instead of blades, blades are installed on a rotating rotor.
- The screw model is equipped with a working screw. It can be single or multiple.
The advantage of rotary equipment lies in the possibility of loosening the soil of any thickness to the required degree. The impact on the soil is from top to bottom. This makes it possible to use a rotary plow with a small traction force of a mini-tractor.
Of all the types considered, the most popular is the 2-furrow reversible plow. It consists of several frames on which tools of various purposes can be fixed. Such equipment is capable of having two functions. For example, while plowing the soil, harrowing also occurs at the same time. However, a homemade plow for a mini-tractor is easier to make single-hull, but it is less efficient.
Independent production of a single-hull plow
It is difficult for an inexperienced person to make a 2-furrow plow for a mini-tractor. It is better to practice on a single-hull design. The most difficult job here will be bending the blade. In production, this is done on machine tools, and at home you will have to use a vise, hammer and anvil.
In the photo we presented the scheme. According to it, the construction of a single-hull type is manufactured.
To assemble a plow for a mini-tractor with your own hands, perform the following steps:
- For the manufacture of the blade, you will need sheet steel with a thickness of 3–5 mm. First, the blanks are marked on the sheet. All fragments are cut out with a grinder. Further, the workpiece is given a curved shape, holding it in a vice. If somewhere you need to correct the site, this is done with a hammer on the anvil.
- The lower side of the blade is reinforced with an additional steel strip. It is fixed with rivets so that their caps do not protrude on the work surface.
- The finished blade is attached to the holder from the back. It is made from a steel strip 400 mm long and 10 mm thick. To adjust the plowing depth, 4–5 holes are drilled on the holder at different levels.
- The body of attachments is made of a steel pipe with a diameter of at least 50 mm. Its length can be in the range of 0,5–1 m. It all depends on the method of attachment to the mini-tractor. On one side of the body, a working part is installed – a blade, and on the other side a flange is welded. It is needed to clutch the plow with a mini-tractor.
If desired, a single-hull model can be improved. To do this, install two wheels on the sides, adhering to the center line. The diameter of the large wheel is selected individually. It is set according to the width of the blade. A small wheel with a diameter of 200 mm is placed on the back side along the center line.

Independent production of attachments, taking into account the purchase of metal, will not cost much less than purchasing a factory design. Here it is worth thinking about how to do it easier.
