How to assemble mills for a walk.Behind tract
Earth cultivation is the desired process when processing it. During it, plowing occurs, but without lifting the lower layer of soil. The cultivator, which is a technique for cultivating the Earth, passes through it to a given depth, loosen the upper section, and then crumbles into small parts.
This leads to alignment of the field. Additional benefit is the purification of the soil of ingrown weeds. In addition, cultivation helps to improve the flow of air into the ground, allows it to warm up faster, gain useful substances, and restrain moisture.
The presence of knives on the cultivator gives the ability to quickly, thoroughly plow various types of soil. With their help, you can process land, and then be content with the following advantages:
- High level of quality plowing;
- Comfortable conditions for controlling the cultivator during soil processing;
- High level of reliability of transmission;
- High efficiency of the cultivator.
There are several types of milling. Each is aimed at their purpose. They are mainly designed for loosening the soil, the creation of a specific structure of the soil layer, which is processed, as well as to combat weeds.
Auxiliary equipment for the walk.Behind tractor
Among the necessary improvements to the walk.Behind tractor in the form of attachment equipment, the following elements are recommended, in addition to all of the above:
For wheels used as motobobes on arable land, wheels with rubber tires are used on arable land. How to make wheels for a walk.Behind tractor with soil.Bearing the experience and the ability to work with ready.Made designs, for example, with steel disks from a tank tree.
The corner is cut into segments of 35-40 cm. The rim of the disk is marked for equal segments. Best if there are. Marks are made and corners are welded in the places of marks.
Do.It.Yourself lift for a walk.Behind tractor is best made from a pipe segment with a diameter of 100 mm. The lift itself is made in the form of a video on the bracket. He, if necessary, changes his position and makes it possible to raise a single tractor to support. In the usual position, the shaft lift is in front of the unit and is used as a support roller when overcoming ditches and potholes.
Do.It.Yourself bucket for a walk.Behind tract is recommended if you plan to use it as a snow removal machine.
- From sheet metal 1.5-2 mm thick;
- Hard plastic with a knife in the lower part of a metal strip;
- From plywood with a thickness of 8-10 mm or OSB plates 10-12 mm.
Bucket is rigidly fixed on the frame of the walk.Behind tractor. To facilitate the work, you can make a rotary device to change the angle of inclination of the cutting plane to the surface of the road.
You can improve home motor vehicles under your requirements without large costs. After all, attaching equipment for a single tractor can be assembled independently, doing everything with your own hands.
It is easy to install the cutter on a single tractor, but for this you will have to pre.Assemble it by organizing the direction of rotation: the sharpened part should crash into the soil.
Fastening is performed on the axis of the output shaft. For fixation, a stopper requires. It is quite difficult to perform installation actions with your own hands alone. It is best to use x-shaped goats made of wood. As a rule, they are made about 50 cm high.
The same-based tractor must be lean on the snufftor, then tilted somewhere to the level of forty-five degrees, substitute a goat under the handle of the steering wheel. Further “Technique”: just take off the wheel.
Before starting the assembly of the milling cutter, you should think over its design, as well as those functions that it should perform. To do this, it is important to view similar products using information in details. Otherwise, the product will not perform the work that is necessary. So, the actions will turn out to be meaningless.

First you need to make at least an approximate drawing, one of these is depicted in the photo. Based on this, all the necessary components are selected. And then you need to act according to the drawing, in stages collecting every detail.
When the assembly of the cutter for the walk.Behind tractor is performed, it is necessary to test. This will immediately make adjustments to its design, if the result will deviate somewhat from the alleged.
It should be noted that the procedure is quite understandable, but for clarity, the assembly of the cutter cutter on the video is also presented. This will allow more thoroughly to understand the procedure, take all steps correctly. Then you get a worthy product and an addition for a walk.Behind tractor that allows you to cultivate the soil especially productively and efficiently. So, the result of such actions with your own hands will be achieved.
Importable assistants in the country and in rural areas: one.Axle tractor and motorbike. Both of these units are driven by a gasoline engine. The main difference is that the first can still transport goods, plow and even mow, and the second can only loosen the soil. Cultivator mills are the knot that makes them similar to each other.
Factory cutters “Goose paws
Not so long ago, mills began to be used for motoblocks, which were called “goose paws”. They have proven themselves well, are most often used to process solid and complex soils. It is such cutters that are used when cultivation should be carried out in difficult conditions, on rocky soils. The design of the “goose legs” is made continuous, which provides the highest indicators of the strength of the equipment. Mills are available in standard sizes:
- Knives width is 41 cm;
- The length of the knives is 38 cm;
- Structure height. 38 cm;
- The mass of the cutter is 16 kg;
- The permissible operating speed of a motor cultivator with such knives is 2-5 km/h.
What are the pluses of the “Goose legs” cutters, is it possible to install it on your own? It is convenient for soil processing, weed fighting. The remaining models will not be able to cope with work better. For rocky and solid soils, the “Goose legs” cutters are simply indispensable. Of the advantages, it should be noted that the steel of cutters in this case is welded. If necessary, you can carry out repairs at home, and not buy new knives, as it is costly.
The cutter of this type also has disadvantages. The main drawback is that ordinary carbon steel is used for manufacturing. The strength of the design itself is at a high level, but the material loses a little other varieties. Such a milling cutter should be regularly inspected when work is carried out on clay soils, with the cultivation of virgin lands. Knizes knives can be curved or simply broken. However, the repair is not too complicated, a welding machine is usually used for a broken knife, after which the fracture is thoroughly polished.
When assembling the circuit, you should work together, since the weight of the design is significant. It is important not to confuse the direction of installation of knives on the axis. When assembling, sharpening should look towards the processed soil. To strengthen the cutter, use a lock, it is placed on the output axis.
Cutter assembly scheme
The photo 1 is well visible design, mill features. The scheme is simple, but before you start using the equipment, you should carefully familiarize yourself with it.
The design of the cutter includes elements such as:
- The rotor axis, which can have a different length (it can be one or divided into 2 parts, t. E. The mill will be collected from 2 parts);
- Short rotary axis;
- The so.Called finger equipped with a fixer;
- Right and left knives;
- Nuts, bolts, washers that are necessary for fastening the entire structure.
Direction of rotation. Counterclockwise. Soil mills of any type are self.Shaping tools, there is no need to use additional sharpening. You should not use sharpening without need, it can ruin the structure.
During the installation of cutters, difficulties may arise, such work is not recommended to carry out such work.
For assembly, special X-shaped goats made of wood are used, the height of which is about 50 cm. This allows you to quickly and easily put the wheels on the design.
Before assembling, the uniform tractor should be carefully covered on a snuffle, and then tilted to about 45 °. Bit goats are usually boards that are lost among themselves in the middle part in the X-shaped position, substituted under the existing steering handle. After that, the wheelchass wheel is removed, cutters of the selected size are placed.
Today, cutters for a walk.Behind tractor can be easily bought at any specialized store, their cost is not too large. With your own hands, you can collect knives for a walk.Behind tractor, but experts do not advise doing it without experience, as they can be dangerous to use. It is not difficult to put the cutter, but it is best to do such work together.

Factory cutters with saber.Shaped knives
Those who begin to use motoblocks ask the question: which knives are best to take? Types of motor cultivators can conditionally be combined into 2 large groups:
Sable.Shaped mills are as suitable for all types of work.
The saber.Shaped form of the milling plant is the most popular, it is precisely such schemes that are called standard. They are effective, the effectiveness of using this particular type has been proved for decades. Often the motor cultivators with which the cutters in the kit are in the set have a saber.Shaped shape. It is as suitable for any type of work. The advantages that have saber.Shaped mills are obvious. The shape of the knives is optimal. They are suitable for performing various types of work. For the manufacture of knives, only carbon high.Quality steel is used, the strength of which is high.
Sable.Shaped mills have a collapsible design, which makes their installation and maintenance simple and effective. The steel from which the knives are made is completely not susceptible to welding work. To improve the mechanical properties of the product, the so.Called thermal tower is used during production. Steel for strength is treated with high.Frequency currents.
Knife assembly recommendations
Cultivator manufacturers try to simplify the assembly of attaching equipment as much as possible. Therefore, the flanges provide for two central technical holes on the opposite sides of the square. They allow you to accurately place cutting elements on the plate.
Location on the plate of technical holes
The rule of the “two holes” the following. When placing the very first knife on the plate, it must cover one of the technical holes and be parallel to the edges of the flange. Further, the installation of the following elements is carried out at an angle to the first. It is extremely difficult to make a mistake in this case and get confused.
Solid shafts with mounting plates can have a special design. The flanges on them can already be with a displacement. They are turned relative to the neighboring one by several degrees.
To facilitate the installation of the blades according to the above instructions, it is not recommended to tighten the nuts completely. This procedure should be performed at the final stage after the master makes sure that the milling cutter is collected strictly according to the scheme.
Production of soil mills “Goose paws
Cutters of this type began to be used massively since the middle of the 80s of the last century. This was due to the development of homemade small mechanization at that time. From then until our time, this design has fully proved its right to exist. Structurally, this module can be divided into several main elements that are made separately and carry different functionality.
Start the manufacture of the soil cutter is desirable from this element. Since the sleeve is subjected to large loads, its manufacture is made on a lathe with a wall thickness of at least 5 mm, optimally 7-8 mm. The inner hole on one side is pulled out so that the milling cutter is freely dressed on the shaft without excessive backlash, tolerance is approximately 0.5 mm.
On the other hand, a groove is made for planting an axial pipe with a depth of 30-40 mm. This will allow you to easily get a compound on the axis. A hole for a fixing pin is drilled.
Axial pipe with flanges
This element is made in collapsible and non.Devastated options for a choice. But there is one feature in favor of a collapsible option. The ability to establish an additional block of knives or vice versa. As the milling cutter behaves, it will finally be found out only after testing and, as often happens with homemade, the result does not always correspond to expectations. For manufacture, standard pipes æ25-32 mm are used.
In the manufacture of the collapsible version, it is necessary to grind the connecting bushings, which are half inserted into the axial pipe and fixed through the holes with rivets or electric welding. The protruding part will serve as a compound for a similar element.
A flange for fastening of the knife racks is welded onto the axial pipe. It can be embedded on a lathe, or can be made of metal strips with a thickness of at least 5mm.
Holes for a bolt or rivet connection to racks are drilled in the flange. The connection of this assembly by electric welding is undesirable due to increased loads.
The length of the tube is selected depending on the location and width of the cutting elements. The number of blanks must correspond to the number of knife blocks. Two blocks are made with drive bushings.
Cutting element (knife)
It is made of durable non-chirus of steel type 65-70g, 3-5 mm thick. The triangular shape of the knife is considered optimal for the least resistance when entering the ground.
As a knife, home.Made people often use a triangular cutting element of a segmented mowing. Since the steel of the rack and the segment has a different composition, welding must be done after vacation with subsequent hardening. Treens with such knives are used in clean areas. For heavy, virgin soils, it is recommended to make cutting elements made of thicker steel, which will make a high.Quality welded joint.
As practice shows, the optimal knife width is 50-80 mm. With large sizes, increased soil resistance is created.
Star of a cutting element
It is most optimal to use the same steel that was used in the manufacture of knives, but it is quite possible to use strong, alloy steels with lower physical and technical indicators.
The stand of the “goose legs” is made from a straight or curved strip of the strip. The edge that is directly in contact with the soil, it is advisable to sharpen.
Holes for fastening on the axial pipe flange are drilled in the rack. Cutting elements are welded with subsequent hardening.
Block of knives
After connecting the racks with knives and axial pipes, an interchangeable modular cutting element is obtained. Only two blocks with ground drives of bushings remain individual.
With appropriate qualifications and the availability of the necessary equipment, the manufacture of this element will not be very difficult. In order to avoid damage to materials and to prevent unnecessary body movements, it is advisable to make a detailed drawing before manufacturing or use the ready.Made.
How to sharpen a home.Made cutter correctly?
Manufacturers of motor cultivators supply equipment with already sharpened standard cutters on sale. However, what to do to a person who made mills for the existing cultivator on his own? In this case, it will be necessary to perform the independent sharpening of the cutting knives of the device.
To sharpen the equipment, you will need an angular grinder equipped with a diamond circle with a diameter of 12.5 cm. Otherwise, you can use the grinding machine, but it will be difficult to use it in connection with the dimensions and the direction of bending of the knives. If the manufactured mills are equipped with small knives in size, then for their rapid sharpening you can use fine.Grained sandpaper.
To sharpen the knives of a home.Made cutter for a cultivator, it is necessary strictly at an angle of 45 °. In this case, it is necessary to independently determine the side that deepens into the soil. It is not required to remove too much metal from the knife, 1-2 sharpening in one season is quite enough. In some cases, the frequency of sharpening knives can change. It all depends on the intensity of use and the type of soil processed.
With intensive work, the cultivator in wet weather will need to monitor the state of the milling. To exclude the formation of corrosion, they should be treated with a special anti.Corrosion compound, which can be found in almost any automobile spare parts store. It is also very important to try to exclude cutters on stones and other solid items. This will help extend the life of operation and reduce the need to sharpen the cutting knives of the device.
