How to assemble a drill chuck on a heavy single axle tractor
How to correctly assemble a cutter on a single axle tractor?
Assembly of the mill can cause some difficulties, especially if you do it the first time and alone.
First, you should familiarize yourself with the structure of the cutter.
The drawing below shows its main constituent elements:
- Rotor axle (comes in different lengths, can be one-piece and split);
- Fingers with locking pin;
- Blades (right and left);
- The construction fastening elements (nuts, washers and bolts).
Also, do not forget to take into account the fact that the movement of the blades during work is oriented counterclockwise. Be careful when assembling the module. any deviation in the design will lead to the fact that the axle will be out of balance, the unit will bring to the side during work.
You can also read about. which thoroughly narrates the assembly process of cutters to the power tiller:
Not so long ago, power tillers, which are called “goosefoots,” began to be used for power tillers. They have proven themselves well, they are most often used on hard and difficult soils. These cutters are used when it is necessary to carry out cultivation in difficult conditions, on stony soils. The goosefoot design is made solid, which provides the highest strength of the equipment. Cutters are available in standard sizes:
Power tiller “houndstooth”.
- the width of the knives is 41 cm;
- The length of the blades is 38 cm;
- The height of the design is 38 cm;
- tiller weight is 16 kg;
- allowable working speed of a rotary cultivator with such blades is 2 to 5 km/h.
What are the advantages of gooseneck tillers, can it be installed by yourself?? It is convenient for tillage, fighting weeds. Other models can not do the job better. For stony and hard soils, the goosefoot blades are simply indispensable. One of the advantages is that the tiller steel is weldable. If necessary, you can make repairs at home, rather than buy new knives, as it is costly.
This tiller has disadvantages, too. The main disadvantage is that they use ordinary carbon steel for manufacturing. The strength of the construction itself is at a high level, but the material is a little bit loses out to other varieties. Such a cutter should be regularly inspected when working on clay soils, when cultivating virgin land. Cutter blades may be bent or simply broken. However, the repair is not too difficult, for a broken blade is usually used a welding machine, after which the place of the break is carefully polished.
When assembling the scheme should work with two people, since the weight of the structure is considerable. It is important not to mix up the direction of blade installation on the axle. When assembling, the sharpening should point toward the soil to be worked. To fix the burr, a stopper is used; it is placed on the output axle.
Active tiller for a power tiller with your own hands
Usually an active tiller for a power tiller is sold as part of the power tiller kit. But sometimes you want to get the job done with a specialized power tiller that is not available anywhere else. In this case, it is necessary to make cutters for a power tiller by yourself.
In this case, you can go two ways: to make a cutter yourself or order the manufacture from a master. The first option is quite time consuming. But a little time and money will be spent on making the cutter, the cost of materials.
The second option has a number of advantages: the availability of the master of all the necessary tools and materials, and as a result, the mill will be more practical.
First it is necessary to think about the functionality and design of the mill. To do this, you should familiarize yourself with analogues. To achieve maximum functionality and safety, all details of the design must be taken into account. If this is not taken into account, the cutter will not do the necessary work, and all the work on its manufacture will be a waste of time. Prepare the necessary materials after you have prepared the drawings. If the design of the cutter contains shaped or pobeditovye elements, their production is ordered in the workshop. And the other elements are bought in a store or use those that are available.
After all the parts are made, it is necessary to assemble a properly working cutter, which is not everyone can do. Assembly must go strictly according to the drawings, without any deviations in the design. Otherwise, the cutter will constantly go to the side, which will make the work very difficult.
After the cutter is assembled, it is necessary to test its work. If the need arises, we remake the tiller so that it performs the necessary work.
How to make tillers for a power tiller with your own hands?
Soil tillers do not have a complicated design. Before making the device yourself, it is necessary 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. Prepare the required materials. If there are shaped parts, it is worth ordering them from a craftsman in advance. The teeth should be positioned in the same way as on store bought products.
All work must be done as correctly as possible to increase the performance of the canopies. Incorrectly assembled design will pull the power tiller to one side.
Sabre-shaped cutters are among the safest. Blades, crosswise, are plunged into the ground one by one, without jerking.
We need to prepare the following materials and tools:
- Metal pipes with a diameter of up to 420 millimeters;
- Sharp parts under the blades;
- angle grinder;
The process of creating an active cutter:
- The blades are sized 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;
- The finished device is installed on the hitch.
Experts say that the optimum diameter of cutters up to 50 centimeters. In this case, the equipment will plunge to a depth of 26 centimeters with a coverage width of one meter. These parameters are sufficient for quality plowing.
To prolong the use 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 gradually lower to begin plowing;
- Sharpening should be repeated as often as possible to achieve a better tillage result.
The most important task of a power tiller in a vegetable garden or field is to fully plow the soil for subsequent sowing and/or planting. In this case, the cutters are used. the main working part of the power tiller. A tiller is an axle with blades of different configurations. These blades rotate on an axis as if cutting the soil layer, ploughing it up. By the way, tillers are also often called soil cutters. This cuts not only the top soil layer, but also all existing vegetation. That is, tillers plow the ground and remove plants-weeds.
There are several varieties of cutters. The most popular are saber-shaped blades. This construction is collapsible. The goosefoots, on the other hand, are characterized by their cast configuration. They are made of carbon steel alloys. Their main feature is considered to be the triangular-shaped knives, which provides full mixing and crumbling of pieces of soil. This shape is explained by the need for high strength when working hard soils.
Features of operation
This nozzle is often used for plowing the soil for planting potatoes, when it is necessary to get rid of large clods of soil and organize the prevention of pests such as Colorado potato beetles. It is worth noting that experienced gardeners and agricultural workers say that this nozzle does not cut down the weeds, but only winds them on itself. Hence the question: does it need to be sharpened? The answer to this will be positive. After you sharpen this nozzle, you can see how small plants will be much easier to cut, as well as making it easier to work with hard soil.
Most often such sheets are used to create goosefoot cutters for power tillers. But there is another type, it is called “active” or “saber” cutter. They are considered the most suitable for the majority of earthworks, their efficiency has been confirmed by many years of research in the field of agriculture. In order to make a cutter for a power tiller, you will need high quality carbon steel, which has a higher coefficient of strength.
Active knives have a collapsible design, which distinguishes them from other types of cutters. This feature will traditionally allow the assembly and installation of active cutters in the most record time: within a few minutes.
The high-carbon steel from which these active blades are made cannot be welded in any way. To increase the characteristic of the mechanical strength of this type of products, during their creation thermo-hardening is used, as well as they are processed by high-frequency electric current.
The so-called “goosefoot tillers” are used in those cases where it is necessary to plow stony and uneven ground. There is an average value of the allowable speed of the milling and cultivator. from two to five kilometers per hour, otherwise no one can guarantee a long service life of the cutters. Remember that if the area you are going to process with a carbon steel tiller has clay soil, then the knife should be regularly inspected for defects.
Cutter types for power tillers
Cutters have quite obvious differences. The main component of a milling cutter is considered to be a knife. Basically, the difference lies in the different designs, that is, in how the arrangement of the blades is ensured, how many of these blades and other characteristics. The material of the cutter directly depends on how well the soil will be treated.
The best forged Italian knives are considered to be those that are self-sharpening. Sheets that are subject to stamping in advance are also often used. But in this case, the edges of the cutter will be less pronounced. These blades are mostly installed on low-end machines.
The main types of power tillers are considered:
The basic elements of power tillers are considered to be sabre cutters. They are included in the basic sets of equipment. These blades are considered the highest quality. They work the soil better due to their strength. Perfect for the heavy tiller.
The main material for saber-shaped cutters is carbon steel. To make them more durable, they are often exposed to high temperatures and hardened by currents. If it cannot be welded, it means that it is a quality product.
Goosefoot tillers for power tillers are a relatively new product. They have not yet proven themselves on the market. Their main purpose is to remove weeds and work with virgin land. The disadvantage is usually considered the fact that they are less durable than saber-shaped. That is why they are often repairable. Due to the fact that they lend themselves to welding, the fact that they are made of standard steel is determined.
Fabrication of equipment. study the tips of experts
Cutters on a power tiller are not distinguished by a complex design. Before you begin to create the elements yourself, it is necessary to carefully study the store options. This will make it possible to take into account all the design features of the equipment and make an effective inventory.
Before the work, you need to make a drawing or use an already ready-made scheme. It will be necessary to specify the material of each of the parts, the sequence and method of attachment.
After that, you need to prepare all the materials. If the design will use shaped elements, it is better to order them immediately from a master.
When making a cutter, special attention should be paid to the correct assembly. Try to avoid any deviations related to the design, because any mistake can significantly reduce the effectiveness of the tillers. over, improperly assembled equipment will pull the cultivator to the right or left.
An important factor is the position of the tines. They must be set in exactly the same position as in the store design.
Experts do not advise to make cutters with a diameter of more than 50 cm. Equipment of this size is able to plunge into the ground to 26 cm, covering a strip, a width of 1 meter. This is more than enough for good plowing.
Sabre-shaped cutters are considered safer and are not capable of injuring the operator if he falls on the structure. The blades on them are transverse and consistently plunge into the soil, without jerking.
To extend the service life of homemade cutters, it is necessary to adhere to the rules for using the equipment. When starting the engine of the cultivator, all the blades must be located above the soil surface. After switching the motor from idle speed, the blades should be slowly lowered and start plowing the ground.
Not knowing whether it is necessary to sharpen homemade cutters, many beginners make a lot of mistakes. It should be remembered that the more often the sharpening is performed, the better will be the result of processing the soil, and the longer the blades will not be affected by corrosion.
By arrangement of the cutters, there are lateral and mounted on the rear of the machine. Lateral ones are mounted on either side of a single–axle tractor, working from the drive shafts of the wheels. In fact, with a similar arrangement, these cutters replace the wheels and drive the technique.
Second kind. PTO cutter is located at the rear of the machine and does not move. Motoblocs of the brands Celina, Neva MB-1 and MB-2, MTZ have exactly this arrangement of cutters.
According to the design of the knives, there are two types of cutters. saber (active, standard) and the so-called goosefoot.
Active cutting unit consists of a set of four powerful blades angled 90° in relation to each other. there may be two or more such sets on one axis. The number of additional cutters and the size of their blades depend directly on the power of the power tiller. Cutter blades of this power tiller are in the form of curved strips bent alternately in different directions. Their design and ruggedness make them easy to work in virgin land, but also allow them to work in places where stones and roots can be encountered.
The second design type of cutters. gooseneck cutters. This product got its name due to the unusual shape of the cutting elements, reminiscent of a goose’s claws. They are triangular in shape and arranged at the ends of the stakes. The number and size of additional blades also depends on the power of a power tiller. mows with more blades means a higher quality of cut.
This cutter is capable of working heavy virgin and clay soils, but in areas with increased vegetation and roots, the product is likely to clog.
Cutter on a single–axle Kentavr tractor: meaning, application
Cutter for the Kentavr power tiller breaks large clods of soil when working, allows for comprehensive tillage, which is the main task of the device.
The mill consists of blades (made of strong steel) which are bolted to the frame. The framework itself is presented in the form of a so-called “herringbone”.
It should also be noted that the active tiller for the power tiller allows first-class processing of the ground, and with minimal labor costs.
