The soil tiller with their own hands

Types of cutters for power tillers

Structurally, a soil tiller is a set of soil tillage blades placed on a rotating axis. This module consists of two parts, which are installed on the drive shafts of the wheels on both sides of the power unit. Thanks to this arrangement, the single-axle tractor is able to move independently during cultivation.

It is also possible to distinguish the type of power tillers with mounted tillers, which rotary motion is ensured by PTO shaft. The module is located behind the power pack and does not participate in the movement. MTZ, Neva, Proab, Sich, Agro power tillers are made in different modifications, with and without PTO.

There is virtually no difference in the construction of both mounted and conventional cutters. But an additional PTO-driven module with a double-sided angular gearbox is available for the cutter with independent rotation.

Active (saber-shaped)

The blade assemblies on these cutters consist of four cutting elements spaced 90˚ apart. There can be 2, 3 or more such blocks on one side of the drive. The number and width of blades depends on the weight of your power tiller and its power.

The blades are curved strips of strong alloy steel. Type 50KhGFA spring steel is well suited for self-building with hardening and tempering. The blade curves alternate in different directions.

Active tiller design allows cultivation of areas with stones and roots without risk of blade breakage. But it is reasonable to use this type of equipment on light soils.


The cutting elements of these cutters are made in the form of a triangle of solid steel at the end of the stand. This arrangement is the origin of the extravagant name “Goose legs”.

As with active milling cutters, the width and number of blade banks are determined by the weight and power of the power tiller. Number of cutting elements arranged on a circle in the knife block, 4 or more. Increasing the number of knives implies a higher quality of shredding the soil, but the power of the power unit will need increased.

These types of milling machines are designed for working heavy soils and virgin lands. The presence of branched root systems in the soil leads to frequent blocking of the module.

Both types of tillers have their advantages and disadvantages. When choosing a variant for self-made, you need to consider the structure of soils, the required degree of shredding the soil, the layout and power of the power unit, the complexity and manufacturing methodology.


Cutter for a mini-tractor is a fairly simple device, which includes several working units. Here is their list:

However, the apparent simplicity is quite deceptive, because this equipment has a very high efficiency and versatility. This unit is particularly capable of replacing a harrow, plough and cultivator in one.

The basic principle is as follows. When the plough is in motion, the drive wheels transmit torque to the cutter shaft. These blades lift the top layer of soil and then turn it over. The principle is the same as that of manual garden digging with a shovel, but of higher quality and efficiency.

The power itself, which is needed to start the tiller’s cutting shaft, is transferred from the main motor to the gearbox via the power take-off shaft. The gearbox itself transmits the torque to the main shaft on which the cutting parts of the tiller are located.

The PTO shaft speed can also be adjusted up or down by means of a gearbox.

Support wheels, in this case, play an adjusting role, correcting the depth of penetration of cutting elements into the soil. The frame aggregates with the minitractor hitch behind it.

The role of the blade guard is also clear. it prevents dust and dirt from getting onto the working parts of the device.

Tractor tiller: types and functions

A tiller is a multifunctional tool that is designed for tillage. With such a canopy is worth working on the ground, where there are no thick roots of trees or stones. Cutter is divided into several types depending on the shape of its blades:

  • Cutter with sabre-shaped blades. This is the most popular tiller. Thanks to the shape of its blades, it can easily cope with a large number of tasks, and is safe to work. If it hits a stone, the blades lift it up and continue their work. This cutter is made of high-quality steel. It is also easily demountable, so you can assemble it in minutes.
  • houndstooth mill. This kind of tiller has become very popular on the market. It is used to kill weeds and for work on heavy virgin soil. A significant disadvantage of such a canopy is a very low strength. As a result, this tiller requires frequent repairs.

Construction, operating features of a tiller

Different tiller models work on the same principle. The cutting blades rotate the shaft, and as a result the blades lift the topsoil, which is similar to what you do when you shovel soil with a common shovel. The design of the tiller makes this process several times faster and more mechanized.

To set the shaft in motion, the diesel engine of the minitractor works, which transmits the mechanical force to a special gearbox installed on the body of the mill. The gearbox starts to rotate the shaft with blades, and by adjusting the power of the gearbox, a person speeds up or slows down the rotation of the shaft.

The depth to which the tiller blades penetrate into the ground can be adjusted by means of depth wheels. And the frame of this device is needed to connect the equipment with a mini-tractor. Working mechanisms are protected from dirt, dust and other contaminants thanks to the protective metal casing on top of the blades and shaft.

Types of tillers

Despite their universality, all commercially available milling cutters for tractors are divided among themselves according to their purpose.

According to this factor, the equipment can be of the following types:

  • cutters for solid tillage. these include garden, marsh and field devices used for the purpose of uprooting stumps and plowing the ground before planting forest crops;
  • specialized cutters designed for digging and cleaning trenches;
  • Inter-row tillers. these implements are used for plowing the soil between the rows during the active growth of crops:
  • Combination tillers. these include milling and sowing implements, and milling and plowing implements.

All of these tillers show the greatest performance in some areas of operation. Their designs are designed to withstand the highest loads in the most severe weather conditions.
