A tiller for the motor-block Neva disk with their own hands

Tips for operating the equipment

After you assemble the equipment yourself, you should conduct a test run with it on the site. Its quality work depends on many factors: soil conditions, weather conditions, proper adjustment and sharpening of working elements and many other indicators.

All adjustments of a self-made fixture are made by trial and error. To do this, it is advisable to first go over a normal patch of ground and adjust the optimum angles and depth of the working surfaces of the scarifier.

Equally important is to determine the optimum working speed for the machine. The right pace of work has a positive impact on the quality of hilling, because at high speed the device will mainly scatter the soil in different directions, thus worsening the process of furrow formation.

Setting up the equipment

Before planting or hoeing potatoes, a test run should be made to see if any problems can be corrected. After fixing the disc mower on the OKA power tiller, it is necessary to check the tightness of the connection, inspecting each detail. Next, choose the area where the test work will be carried out.

Make any necessary adjustments to the hitch beforehand. When the machine is in operation, listen to the sound made by the equipment. There should not be any creaking or other suspicious sounds.

Check the ridge profile, the quality of the grip and the distance between the working elements that sink into the ground. Adjust the angle of attack on the discs. It is important to consider the speed of tillage, which will correspond to the power of the OCA and the attachment itself.

Types of ridgers

The easiest way is to use a hoe or hoe to loosen the soil in between the rows and sprinkle the soil under the bushes, forming mounds. But it’s much easier to form the ridges with a hand-held potato planter. Hanging such a device on a single-axle tractor or electric cultivator, you can quickly cultivate even quite large areas.

In specialized stores there are a variety of models of okuchnikov, each of them has its own principle of action. When choosing a tool for yourself, you need to consider the size of the area to be worked, and if you have a single-axle tractor or other machine, the make and characteristics.

Depending on how they work, there are different kinds of riders:

Share breakers are classified according to the design of the working element as follows:

In Fig.1 and Fig.2 shows the hand-mounted planters. These models are usually fitted with one operating element and comfortable handles (for two people to work together).

Types of rocker arms for power tillers

Conventionally, the rocker for power tiller according to its design and principle of operation can be divided into several basic types:


This design is the simplest of all. These sharecroppers have a fixed working width and look like butterfly wings.

The construction of this device consists of two branched, connected and fixed sheets of iron. When working, the rocker must lift the soil from the flat surface to the top, while overcoming the resistance of the ground and creating the necessary ridge. The pointed end of the implement must drop below the soil surface to a pre-determined depth. It loosens the soil and lifts it, and to guide the soil to the base of the plant are guiding planes that create a slump of soil on both sides.

Since the wings are fixed in this set, when working with it, you have to adjust the row spacing to the size of the device, and not vice versa. So, given that the optimum width between the rows when planting potatoes is considered 60 cm, the width of the grabber factory at 25-30 cm is not very convenient when growing potatoes. Structural improvements for the opener relate to the size of the wings and the angle of their installation to reduce soil resistance and change the width of the capture and height of the furrow ridge.

Variable width machine

This device is the most convenient, because it has an adjustment mechanism that allows you to quickly and easily change the position of the wings. It’s precisely because of this design solution that the mower head can easily be adjusted to different row sizes. One unpleasant disadvantage of such a mechanism is related to the fact that during the ripping process the wings move the earth in different directions, but not a very large amount of it falls back into the furrow. But despite this inconvenience, this model is more popular with many farmers.


The name of the implement itself suggests that it works with discs whose thin rims run into the ground at a shallow depth with little resistance. For quality and easy work this design requires precise adjustment of the angle of approach and the vertical angle of the discs. The distance between the working discs is set on the frame according to the size of the row to be worked.

This type of tool has a number of advantages:

  • Perfectly matches up with the power tiller. When using this type of tool in a lower gear of a power tiller its power increases. Therefore, the efficiency of digging the soil increases much more, and also has a beneficial effect on the work cycle of the tool.
  • Very comfortable to use. Loosening and digging up the soil with little physical effort. A properly adjusted device does not require additional support from behind, and moves along the ground as if on its own.
  • Versatility of use. Such a tool is convenient to use for loosening the soil during the potato planting period, as well as during the vegetation of the plant.


This type of planter is also called active, because its principle is based on both rotational motion of working elements, and their forward movement. This kind of equipment can be used only on power tillers with two forward gears and a power take-off shaft. In appearance, the design resembles a home fan.

The use of such equipment is much more effective than other models, but because of the complexity of manufacturing and the high cost of components is used much less often their.

The entire work process of the propeller elements is carried out in a single rotation of the active disc. First the soil is dug up and weeds are pulled out, then the ridges themselves are loosened.

At maximum power, this device can be used not only for groundwork, but also to move the ground to another place.

Preparation of materials and necessary tools

In order to make a homemade disc coulter, you need to choose the type, decide on the dimensions. An important condition for obtaining quality equipment is to do with their own hands drawings. If you are not good at it, you can use a prefabricated type. They should consist of a general assembly and its parts. All dimensions must match, then there will be no difficulty in assembly.

Disc tooling has a component such as the fender gripper. Its width can be constant, or you can change it by rearranging the legs. Therefore, it is possible to make the necessary mounted equipment of two varieties: with a constant and varying magnitude of capture. When working with the first kind of product, the formation of the distance between the rows should take into account its length.

The other type of attachment tool has no such disadvantage, as it can always be adjusted to any rows, making it easier to work the power tiller. But often in working moments, when the soil gets into the furrow, you have to get rid of it. Because of this, the efficiency and workability of the tool is reduced.

  • discs in double quantity;
  • two screw-shaped turnbuckles;
  • double number of tines;
  • a T-shaped leash.

Consider the work of the disk hoe. As they move, the discs grip the ground and create an embankment, covering the seedlings. Through rotation, the soil is crushed and loosened. The disc coulter on a single-axle tractor consumes less power compared to other types and is more convenient to work.

Step-by-step making of the lister perch

The simple design of the lister, or ploughshare, perch gives it preference over other devices. To make it:

  • Take a sheet of iron, bend it in the shape of wings. The parts are machined with an angle grinder and welded at the joints
  • To attach the toolbar to the tiller, a mounting bracket is needed. Connect the T-arm to it with two bolts.
  • The stopper is inserted into the square tube and pressed on the outside.
  • Bracket with rocker arm pivot, secured with two bolts, so that the arm is in line with the longitudinal axis.
  • Use nuts to secure the position.

You can save on rocker parts by replacing a sheet of steel with a forty to sixty centimetre-diameter pot lid. This unsophisticated implement is bent with a hammer and the edges are ground. The simple rocker arm is now ready for use.

For the construction of a two-row mounder, the base is prepared from a three-millimeter sheet of iron.

The bracket will be a four millimeter strip of steel, and the field board will need a sheet one millimeter thicker than these parts. The main load bearing structure will be the bar. So it must be strong and stable.

Even someone with no knowledge of locksmithing can make a lister model of the planter. The device prevents overloading the power tiller when the equipment is buried in dense layers of soil.

Tilling potatoes with a plough

If you have a power tiller, the potatoes can be tilled with a special single or double row plough.

If a two-row plough is used, the plough’s tines are connected via extensions. The wheels should be bigger than those used for ploughing. This technical solution in increasing the diameter is necessary to prevent damage to bushes during mowing with the bottom of the power tiller.

Set the ploughs so they are in the middle between the potato rows when in working position. Then each element of the plough is driven into the ground to the required depth and the axis of the mechanism is set vertically to the soil surface. This is done to allow the stalks to dig into the soil while working. Mowing with a two-row plough should be done in a row, because furrows are created on both sides.

When using a single-row plow, it is necessary to set the ground shoes closer together. This is necessary because the mowing will be done in one row spacing, and if this requirement is not met, the single axle tractor may not pass without damaging the bushes.

In addition to the methods presented, it is possible to weed and dip the active tiller, when on a power tiller also extensions are used for groundhogs.

The device itself is a metal wedge equipped with wings or rotating discs mounted on the frame. Potato tillers are attached to the tiller with the help of a special attachment. Above all, the device allows you to plant potatoes with minimal effort with a power tiller.

Due to the fact that the passage in one direction makes a furrow, and in the opposite direction. it is evenly filled to the height required for these crops, the planting is greatly facilitated. As necessary, the same equipment helps to loosen, hill and destroy weeds.

In this video we will look at the potato mowing with a power tiller:

A homemade disk hoe for the power tiller

Any equipment is made in accordance with the drawing, which you can build yourself.

Design and construction

It is necessary to consider the design features of the manufactured equipment, which depend on the type of motoblock, the type of planned work, as well as the personal desire of the owner of the equipment. The device can have different forms of curved planes. On its surface, which is immersed in the ground, you can apply a massive tip, which is relevant for planting work, as well as activities related to harvesting.

The lems or flaps are made with a bend or slope. They can also have adjustable and non-adjustable profiles.

By providing the sliding wings and adjustable distance between the elements, you can simplify the processing of land, as well as expand the functionality of the device.

Materials and tools needed

Before making a device for a power tiller, you need to prepare materials:

  • A sheet of steel, at least 3 mm thick;
  • uprights;
  • leash;
  • turnbuckles;
  • Fixing bolts;
  • washers;
  • locking elements;
  • disk wheels.

It is impossible to make a homemade rocker arm for a power tiller without tools:

Fabrication and assembly

How to make? In order for the manufactured tool to perform its assigned functions, it should be assembled in accordance with the algorithm:

  • Draw the drawings.
  • Make a template out of paper and then out of steel with a minimum thickness of 3 mm.
  • Cut out the halves of the equipment.
  • Bend the workpieces until the outer side of the workpiece is parallel to the radius line
  • Carry out welding with an electrode according to the type and thickness of the metal.
  • Work on welding seams with an angle grinder to eliminate the roughness and irregularities that would later interfere with the assembly and normal operation of the device.
  • Check that the elements are securely fastened.
  • Repeat the welding for checking.
  • Grind the edges with an emery wheel mounted on an angle grinder.
  • Bolt the stand, leash and turnbuckles together in a “T” shape.
  • Weld the components.
  • Fit disc wheel adapters to disc wheels.
  • Adjust the position of the discs.
  • Attach the device to the power tiller bracket through the leash, using bolts with washers and locking elements.
  • If you want, you can make the mounting of the pre-emergence discs adjustable.

To be able to carry out its intended function without problems, the discs must be perfectly smooth, free of burrs and irregularities.

A homemade machine has a number of advantages over store-bought models, because it can be easily assembled, rebuilt, and repaired. Potato tiller is easier to make to power tillers Neva, Salyut and other well-known models because of the ease of attachment of the device to the equipment.
