Is it necessary to sharpen tillers on the tiller?

How to make cutters for a power tiller with your own hands?

Soil tillers do not have a complicated design. Before making the device yourself, you need to pay attention to store analogues to assess the design features and make an effective inventory.

Drawings are needed with exact dimensions, specified parts, sequence and connection options. Materials must be prepared. If you have shaped parts, it’s worth ordering them from a craftsman beforehand. The teeth should be set in the same way as for shop-made products.

All work must be carried out as correctly as possible to improve the performance of the linkage. Incorrectly assembled design will pull the power tiller to one side.

Sabre-shaped cutters are among the safest. The blades, transversely arranged, plunge into the ground one by one, without jerking.

It is necessary to prepare such materials and tools:

The process of creating an active tiller:

  • Blades are adjusted to size and bent at a certain angle in one direction;
  • Blades are welded to the pipe from different sides;
  • It is better to pre-sharpen the blades behind the movement;
  • Ready to be mounted on a tractor hitch.

Experts say that the optimum diameter of cutters up to 50 centimeters. In this case, the equipment will sink to a depth of 26 centimeters with a coverage width of one meter. Sufficient for good ploughing.

To extend the life of homemade cutters, it is worth following the rules of operation of the equipment:

  • When starting the motor, the blades must be positioned over the ground;
  • The engine shifts from idle speed and the blades are gradually lowered to start plowing;
  • Resharpen as often as possible to work the soil better.

Which ones are best?

Cultivator tines are best suited to each job and each soil type. Sabre tines raise weeds by loosening the soil to a depth of up to 35 cm. At the same time, they do not cut them into small pieces, but reel them in and swath them. Than prevent them from multiplying. In addition, a coarser “fine-grained” soil is produced. But on dense or virgin soils, sabre blades do not go into the ground well. Larger and climbing weeds quickly wrap themselves around the working area and slow cultivation.

Goosefoot cutters are great on difficult soils and all kinds of weeds. But because they are cut into pieces with a sharp edge, the weeds multiply. There is a combined use option. In the fall, you should pass the site with these cutters, and in the spring and during the season, work with sabre cutters.

Homemade tillers for power tillers

The power tillers of any firm will be with factory installed models. But it often happens that a farmer wants to increase the power of his cultivator. This is caused by the need to work the ground deeper. To achieve the goal, it is possible to make the blades yourself. To do this, it is necessary to exactly follow the technology to get a good tool.

The easiest thing would be 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 pipe.

Usually, farmers make homemade models for their intended purpose. So, when sharpening them, it is important to choose the direction of the blades. 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 of the time needed to develop more efficient methods of processing the land. That’s why they began to design their own models of milling machines for cultivators.

The now-famous “goose feet” is a model that was the result of homemade products. Using the drawings of the then craftsmen, manufacturers decided to start conveyor production of blades of a new type. Now, what was once assembled “among the people” is produced at each factory of the manufacturer of milling cutters for cultivators.

How to make a milling machine “goose feet” with their own hands: drawings and schemes

A single-axle tractor is a truly versatile machine, which is a great helper for the farmer whose farm size has not yet reached the size that would make it necessary to buy a tractor. In addition, the single axle tractor is much more compact. Depending on the attached equipment, it can replace many individual units, saving the owner a lot of money. The burr is one of the most important attachment types. Therefore, many owners puzzle over how to assemble a tiller on a single-axle tractor and how difficult it is to do it themselves.

Comparison

The goosefoot attachment is suitable for heavy soils. It can be used on different modifications of power tillers due to the variability of the sleeve. These models are easier to control during work, but they are afraid of jerks and bumps in the process of ground treatment. Active analogs or factory-made products do not always work on heavy soils. This is especially true for variants with Chinese knives, where the quality of metal leaves much to be desired. Not only will it be difficult for the user to hold the machine in his hands, but in addition, the load on the gearbox will be significantly increased.

These tillers can be repaired by removing damaged elements and replacing them with new ones. In addition, there is a width lock. By the will of the operator it is possible to place in a row additional pairs of cutters.

If you know beforehand that the cultivation of difficult soils is required, it is either necessary to choose high-quality milling machines from Ukraine and Poland, or look for other modifications.

As for spiral milling cutters, called “Virgin”, this design is fully welded, which is done precisely to increase its strength characteristics during operation. That’s why it can withstand heavy loads. The only thing the user may not like is the slowness of operation. But this is understandable: you won’t be able to overclock on the virgin soil, no matter how much you’d like it.

If you want to buy exactly this version of the tiller, it is important to consider another disadvantage. during cultivation, the soil will be pushed from the center to the edges. This will produce a shallow furrow that may require levelling the land later on. As for the rest, spiral milling cutters are considered more reliable devices in comparison with other analogs. They are rugged, reliable and durable. If you want to cultivate the soil in a difficult spot, they are the right tool for the gardener.

Cutter varieties for power tillers

Cutters on a single-axle tractor may differ from each other in shape and design, number and location of blades. They are mounted on the rear of the power tiller and depend on the PTO. Power tillers give the best result when the speed is increased.

The general structure of the tillers can be described as a set of tillage blade blades, placed at different angles on the blades, welded or fastened to the rotary axle with fasteners.

The blades enter the ground smoothly and alternately, which is good for the powertrain of the power tiller.

Active saber blades

Power tillers come standard with sabre blades. They are effective and popular with farmers.

The tiller for power tillers has a demountable design, so installation, maintenance, repair and transportation are as easy as possible.

The units, consisting of 4 cutting units at 90° to each other, held together by bolts, nuts and washers, are installed on the rotating axle instead of the wheels. Number of units on each drive side: 2, 3 or more. The number and width of blades is affected by the weight of the machine and its power.

The blade of an active tiller for a power tiller is a strip curved at the ends. The bends are directed alternately in different directions.

In factory conditions blades are made of hard alloyed or high-carbon steel with obligatory thermal hardening and high-frequency treatment. In case of self-made nozzles, masters recommend to use spring heat-treated and hardened steel 50ХГФА.

Goose legs

The goosefoot attachments are relatively new. High efficiency is achieved by their specific shape. cutters are of solid construction and cannot be dismantled. blades are in the shape of a triangle on the end of the stand.

Factory standard cutters have these dimensions:

  • the width of the knives is 41 cm;
  • Length of cut. 38 cm;
  • The tool is 38 cm high;
  • weight. 16 kg;
  • The nominal operating speed of a tiller with cutters is 2-5 km/h.

Low-carbon steel is chosen for soil tools production. The knives are self-sharpening, if used carefully, they do not need to be sharpened.

How to assemble properly a cutter on a single axle tractor

A power tiller is a piece of equipment, without which you can not do without in agriculture. It is intended for agricultural works. To assemble the blades on the cultivator and prepare it for tilling the land, you need to do some.

First, it is necessary to get acquainted with the cultivator, for which the cutter will be made. We need to study its design. This will save time and assemble the finished unit. It will be most convenient to assemble either saber-shaped blades or goosenecks.

Studying the design of a power tiller, it is necessary to pay attention to:

  • The power of the cultivator;
  • The top frame of the power tiller, on which the fuel tank and engine are located. They will be attached to adapted brackets;
  • Equipping a Moto-block or engine with a clutch and a gearbox.

Cultivator consists of such elements:

  • Short, rotary axle;
  • Rotor axes of varying length, assembled from two parts;
  • A “finger” with a clamp;
  • Blades (right and left);
  • Bolts and other parts to secure the entire structure.

The assembly of the cultivator cutters is as follows. A total of 24 blades are installed. The scheme consists of two blocks of 12 blades each. Each unit uses 3 dedicated nodes of 4 blades. They are mounted strictly at an angle of 90 degrees. To create one blade, a sheet of steel with a thickness of no more than 5 millimeters is taken.

To make the stands, a steel angle of 63×40 millimeters is taken. The blades are attached to the stand, and the other end is welded to the flange. So it is possible to connect 4 blades in one unit. Then the whole installation is bolted in place.

If you follow these instructions, you get a solid and reliable construction, which can easily withstand most of the loads. For regular use of equipment, it is recommended to resort to factory models, rather than homemade knives. This contributes to productive operation of the unit without failures and problems.

Another popular variety of tiller for a motor-block is “virgin”, which is in great demand due to its spiral shape. The distinctive feature of this type is its one-piece construction, which allows it to cope without problems even with enormous loads.

The main disadvantage is the slow work, as well as the fact that in the process of tillage the soil is pushed out, resulting sometimes in small holes.

As for the advantages, there are a huge number, among which the following can be highlighted:

  • Unlike other varieties of tillers for power tillers copes well with virgin soil;
  • It is characterized by an impressive cultivation depth;
  • Allows high-quality processing of the soil;
  • Features a monolithic construction, which is a sign of reliability, strength and durability.

Cutter types

The attachment consists of four curved blades. “petals”. mounted on a shaft. Most of them are of the directional type: when assembling it is necessary to consider the direction of movement. blades are usually bent on both sides, except for those at the ends of the shaft. There are models in which all the “petals” are bent only towards the gearbox: this prevents crop damage when ripping. This, however, reduces the working width.

The elements are made of pressed steel. for the lightest machines. and of steel strip, often forged. The latter variant is the sturdiest. The tiller is usually a separate piece, but there are also models in which two tillers are attached to a single shaft.

  • Sharpened. it is easier for the ‘petal’ to dig into the ground and prevent adhesion. Correspondingly, the engine load and fuel consumption are reduced. On the other hand, the sharp blades cut the roots of weeds, some of them remain in the ground and sprout again. Sharpened cutters should be used with great care.
  • with a semi-circular edge. safer, but more resistance during ripping, more often gets stuck. This element removes weeds more effectively, because it does not cut, but winds up the root and pulls it out of the soil.

Cultivator cutter diameter determines the maximum plowing depth. the relative is set by the coulter.

  • rivets. the element cannot be disassembled. The difficulty is not so much in storage as in transportation;
  • bolted. the element can be disassembled. Here is a sample in the photo.

Welding is not used for joining. this reduces the strength of the product.
