How to correctly place the blades on a cultivator
Which are the best?
Cutters for a power tiller are selected for each type of work and depending on the soil structure. Sabre-shaped cutters, loosening the soil to a depth of up to 35 cm, lift weeds to the surface. They don’t cut them up into small pieces, but wrap them around themselves and the rollers. Than prevent them from multiplying. In addition, a coarser “fine-grained” soil is produced. But on dense or virgin soils, the sabre blades do not penetrate the ground well. Large and curly weeds quickly wrap themselves around the working part and slow down tillage.
Goosefoot cutters are great for difficult soils and all kinds of weeds. But because they cut them to pieces with a sharp edge, the weeds multiply. There is an option of combined use. In the fall you should pass the plot with these cutters, and in the spring and during the season work with sabre cutters.

Such equipment as a tiller is essential for any power tiller, as it can be used to perform most of the work associated with tilling the soil. Generally the tiller comes with the machine, but in cases where you need to change the width and depth of cultivation, you should buy the equipment separately.
Additional power tillers increase tiller functionality and make the work with a power tiller easier. Specialists recommend having several pairs of cutters in your arsenal.
What’s the best power tiller for your power tiller??
Such “knives” for tillage can be divided into two large groups. Each of them has its own characteristics and is suitable for a certain type of work.
Sabre-shaped power tiller for a power tiller
The most popular and versatile models, which are effective in carrying out various earthworks. These models use the optimal form of knives, for the manufacture of which manufacturers choose high-quality durable steel.
The models have a demountable design, so they are easy to install and maintain.
These models are relatively new on the market. They can be used to till any virgin land and are efficient in hard and rugged terrain. Features of this type of cutter:
Such models, unlike saber-shaped cutters, are made from carbon steel, which is a little less durable.
Cutters for a power tiller homemade
Manufacturers offer different versions of tillers for power tillers. You can use one set of cutters or buy two different types of devices, changing them depending on soil conditions. Some craftsmen prefer to use homemade products, which, if properly assembled, will be no worse than the factory ones.
The main advantage of independent creation of a tiller is that it can be adjusted to the specific features of the plot.
How to assemble the right cutters on a single axle tractor?
The assembly of the tiller with your own hands should be carried out as correctly as possible. And here it is especially important to make sure that the active part cuts into the ground during work. For this purpose it is initially recommended to study the drawings, and then already proceed to the construction of the equipment.
The sabre and its assembly
Before assembling a tiller on a single-axle tractor, you need to get a good understanding of the concept of a power tiller. It is a welded frame made of pipe with a diameter of at least 23 mm, with a fuel tank and engine mounted on it. They are attached to the frame with brackets. The engine is otherwise known as the power unit. It is equipped with a gearbox and a clutch mechanism. Each brand of cultivator has a different power unit with different power.
When installing the tiller on a single-axle tractor, some craftsmen have difficulty. That’s why it is recommended that two people do the work. Assembly is usually done on a purpose-built wooden trestle about 50 cm high. They help you get the job done faster. the single axle tractor rests gently on the coulter bar and tilts at an angle of about 45°. The handlebar is fitted with trestle pins. In this position, the wheels are removed from the power tiller and the cutters are installed (image ). On the outer ends on the right and left you need to install the plates on the tillers for the power tiller. They improve the machine’s performance and make it run smoother and more stable.
How to assemble a tiller for a power tiller
Cutters for Aurora power tillers and power tillers are supplied in a disassembled condition like many other producers. Often, for owners of new machinery becomes a bit of a problem the process of assembling tillers. In this article we will describe how to assemble working milling cutters from parts of this construction kit. For Aurora machines, depending on the model, the cutters are available on axles of two sizes. Diameter of the axis, for light equipment is 23 mm, and 32 mm for heavy equipment.
Cutters for light tillers and power tillers are assembled quite easily. To do this, install the blades in the special mounting sockets and screw them on. Pay attention to the direction of the cutting edge of the blade. It should face the direction of travel of the power tiller. In addition, each blade is marked. If the letter quotRquot is shown, it means it is turned to the right, respectively quotLquot to the left.
Each subsequent section is secured to the previous one by a pin and locked by a pin. The cutting disc must be secured with a bolt. Depending on the power of the machine, the number of blades will be different. Their number can be 24, 32 or 40.
The number of blades can also be different and can be three or four per section. This is due to the number of attachment plates on the axle. If the tiller axis is straight with no offset, the number of blades is three. For models with offset. four.
Four-blade cutters are assembled sequentially, one left, one right. To assemble the cutters will be easier, if at the very beginning divide the left and right blades into two parts, for the left and right cutters.
The three blades are assembled differently. The first blade is mounted on the axle and fixed with a bolt. Later on this bolt will have to be removed to fix another blade. If the first one was mounted on the outside of the plate, the remaining two should be mounted on the inside of the attachment plate. The quotLquot and quotRquot markings for the three-blade cutters are set separately for each side.
To make trailing blades for your power tiller, first of all you need to find the drawings, which will guide you during the work. The easiest way to make homemade grousers is to use discs from a car. With the help of a welding machine a metal strip is fixed on them, on which plates-grosser plates are subsequently fastened.
Next, in order to make the tines, it is necessary to make teeth, for which a steel plate of sufficient thickness is used. The length of the teeth depends on the model of the power tiller, and they are fixed to the rim with a spacing of 15-17cm. Such soil seeder for a motoblock perfectly copes with its functions and, if made with quality, does not disappoint its owners.
Another way to make your own trailing blades for your power tiller is to use a used gas cylinder. In this case it is necessary to cut two disks from it, which will become rims, the width of which should be from 6 to 10 cm. Their height will be 30 cm. Then a metal plate is installed on them, just like in the case of car wheels, to which the tines are mounted. Their length should not be less than 15 cm. If necessary it can be increased at your discretion, but the main thing is not to overdo it.
A handy homemade planter for a power tiller
Seeders for power tillers are subdivided by the number of simultaneously sown rows. from 1 to 5, there are also vegetable seeders and precision drills. Vegetable planters are used for precision sowing of vegetables: carrots, onions, beets. The seed feeder is driven by the support-driven wheels of the sections. In addition, the rotation speed of the machine can be adjusted by changing the sprockets.
Vegetable precision drills have a brush sowing device. In such a device a rotating brush draws a layer of seeds into the hopper and the seeds are poured into the hole in the back of the hopper. The hole is closed by a rotary disc that has holes of different diameters. By turning the disc, the holes can be adjusted and thus the seed rate can be changed.
Homemade seed drill for power tillers is usually connected to the tractor with a universal coupling, thanks to which you can complete a single-axle tractor with two-row and four-row seed drills.
Types of cutters for a power tiller. varieties and description
All commercially available tillers for cultivators lend themselves to a certain classification.
There are such types of equipment on the market:
- Cutters equipped with saber-shaped blades. devices of this type are considered the most popular among buyers. The high efficiency and performance of such designs has been proven for several decades and a mass of satisfied farmers. The main advantages of these burrs include their optimal shape, manufacturing material and processing methods. They have a collapsible design, which allows you to quickly replace a broken part. Today, almost every cultivator Kraftsman, Neva and Hyundai is equipped with sabre milling cutters;
The most common and popular type of cutters for motocultivator is considered to be the “goosefoot” knife model. They can be made by hand with a basic set of tools. It is recommended to use on the farm only those types that have been made by following the forging technology and have self-sharpening properties.

Knives differ in their shape and principle of operation. For example, these “goosefoots” differ in the presence, location, and design of the cutting edges. The material used in the cutter production plays an important role. Depending on the quality of the material, the level of depth as well as the quality of tillage of the ground layers depends on.
Let’s look at specific examples of varieties of cutters:
Sabre-shaped power tools
Sabre-shaped cutters are standard on all power tillers. They are used in the factory. Most farmers use active sabre cutters. Among the advantages of this type stand out:
If the blades are factory-made, a sheet of alloyed or high-carbon steel is used as the material. It is heat-hardened, treated with high-frequency electric current. Not recommended for use with cluster milling cutters.
If it is necessary to use a self-made cutter, it is recommended to use hardened, heat-treated steel. For example, structural spring steel 50 XGFA.
Goosefoot blades appeared in 2000. Since then, the blades have become popular because of a number of useful qualities. They appear due to the special shape of the blades. If you look at them, they resemble goose legs, which is why they got their name. The construction itself is one-piece and cannot be dismantled.
Factory-made products are characterized by their static parameters. Among them, the standard dimensions for blades look like this:
The cultivator can reach speeds of up to 5 kilometers per hour with the working blades. For work with soil, it is customary to make them from mild steel. This allows the knives to be self-sharpening. So, with proper handling, they may not be sharpened at all.
People use goose-feet to work virgin land or other difficult soils. It is not recommended to use these knives when working on land that has a lot of roots. Because of these, the system will constantly clog and delay work in the field.
Any company’s power tillers will have factory-mounted models. But it often happens that a farmer wants to increase the power of his cultivator. This is caused by the need of deeper tillage. To achieve the goal, it is possible to make the blades yourself. To do this, you need to follow the technology exactly to get a good tool.
It will be easiest to make and assemble a sabre cutter yourself. To do this, you need to acquire a metal strip of high-strength steel, an angle grinder, additional tools for direct digging, a welding machine and a small-sized pipe.
Usually farmers make homemade models for a preconceived purpose. Therefore, when sharpening them, it is important to choose the direction of the blades at once. This will give them useful properties in the form of increased power and quality when plowing.
Homemade models work much more efficiently. This distinguishes them from their factory counterparts. Homemade knives began to be widely used back in Soviet times. Farmers at that time needed to develop more efficient methods of tilling the land. So they began to create models of milling cutters for cultivators according to their drawings.
The now-famous “goosefoot” is a model that resulted from homemade products. Using the blueprints of the craftsmen of the time, the manufacturers decided to begin conveyor production of the new type of blade. Now, what was once assembled “among the people” is produced in every factory of the cultivator milling cutter manufacturer.
Another popular variety of power tiller for the motor block is the “virgin”, which is in high demand due to its spiral shape. The distinguishing feature of this type is its one-piece construction, which allows it to cope with even enormous loads without problems.
The main disadvantage is the slow operation, as well as the fact that in the process of working the soil is pushed out, which sometimes results in small pits.
As for the advantages, there are a huge number, among which we can highlight the following:
- Unlike other varieties of tillers for power tillers copes well with virgin soil;
- characterized by an impressive depth of cultivation;
- allows you to qualitatively work the soil;
- Features a monolithic design, which is a sign of reliability, strength and durability.
