How to make a cutter on a single tractor. Axial pipe with flanges
Soil milling cutter and cutters Goose paws for a walk.Behind tractor
Structurally soil cutter is a set of soil processing knives placed on a rotating axis. Such a module of two parts is installed on the drive shafts of the wheels on both sides of the power unit. Thanks to this location, the unoic tractor during cultivation is able to move independently.
You can also distinguish the type of motoblocks with hinged cutters, the rotational movement of which gives the power shaft of power. The module is located behind the power unit and does not participate in the implementation of movement. Motoblocks of the type MTZ, Neva, the foreman, Sich, Agro are just produced in various modifications, with a power shaft and without.
There are practically no differences in the manufacture of both hinged and ordinary mills. But for a milling cutter with independent rotation, an additionally made module with a drive of the power shaft and an angular double.Sided gearbox is made.
Blocks of knives on such cutters consist of four cutting elements located 90 ° after. Such blocks on the one hand of the drive can be 2, 3 or more. The number of knives and the width of the module depends on the weight of the walk.Behind tractor and its power.
Knives are curved stripes of strong alloy steel. For self.Manufacturing in the presence of heat treatment, followed by hardening, spring steel of the 50khffa type has proven itself well. Knife bends have a different direction alternately.
The design of the active cutter allows cultivation in areas with stones and roots without danger to break knives. But applying this type of equipment is advisable on light processed soils.
The cutting elements of such mills are made in the form of a triangle made of strong steel located at the end of the rack. This arrangement caused such an extravagant name.
As in the case of active cutters, the width and the number of knife blocks is determined by the weight and power of the motor.Cultivator. The number of cutting elements located around the circumference in the knife block from 4 or more. An increase in the number of knives involves better grinding of the soil, but the power of the power unit will need increased.
Rotor mower for a walk.Behind tractor can be useful to you at a summer cottage.
These types of milling plants are designed to process heavy types of soils and virgin lands. The presence of branched root systems in the soil leads to frequent clogging of the module.
Both types of treading mills have their advantages and disadvantages. When choosing an option for independent manufacture, it is necessary to take into account the structure of soils, the necessary degree of grinding of the soil, layout and power of the power unit, the complexity and methodology of manufacturing.
The design of the walk.Behind tractor
Before assembling the cutter begins, you need to figure out what the motor cultivator is and what is included in it. The upper part of the frame is usually welded. The fuel tank, engine are installed here. Fastening is carried out on brackets. The engine itself, or power unit, is equipped with a clutch and gearbox. Its power can be different, it all depends on the type and purpose of the motor.Cultivator.
Cutters are a scheme of 2 blocks, each has 12 separate mills. For each block, 3 separate nodes with 4 knives are used, which are mounted at an angle of 90 °. The position of the nodes has a displacement of 30 °. For the manufacture of one knife, a steel sheet is used, the thickness of which is 5 mm. The stand is made of a metal corner of 6340 mm. The knives are attached to the rack, the second end is welded to the flange to combine 4 knives into one structure. The whole mill is connected by bolts, washers, flanges. The design is reliable, it is able to withstand significant loads. If it is planned to constant use of this equipment, then you need to prefer only factory options.
How to make homemade mills with your own hands
If the cutters are worn out or there is a need to modernize the cultivator, for example, to increase or reduce the depth and width of cultivation, they can be done with your own hands.
In many cases, this improvement allows you to improve the quality of soil processing, to perform work faster.
The design of these parts is simple, so you can make them yourself.
The easiest way to construct home.Made “Goose legs” make.Ups for a walk.Behind tractor with your own hands is to study the device of industrial mills and make your necessary changes.
It should be noted that when the “Goose legs” milling cutters are made with their own hands, drawings for different types of motoblocks are developed individually.
The figure shows a classic version of a 4-row industrial mill.
- Sleeve. For its manufacture, you will need a pipe with a diameter of 50 mm and a wall thickness of at least 4 mm.
- Flange. It is made from a steel sheet with a thickness of 5-15 mm. It can be formed in the shape of a circle, but it is easier to make in the shape of a square.
- Star of a knife. Material. Steel corner with shelves 63×40 mm. You can use automobile springs. Often the rack is made of a steel strip. This is the cheapest option, but also the most unreliable. During operation, the stand plays the role of a vertical plane cutter.
- The extreme left knife.
- Middle knife.
Knives are made of instrumental steel. Many craftsmen use automobile springs to make knives. Forms of knives can differ significantly. The angle of sharpening is usually 45 °. In the process of work, the knives are blunting, so periodically they need to be sharpened.
With the help of a welding machine, knives are welded to the racks, racks. To flanges, flanges. To the sleeve. This is how the indispensable design is assembled. Some craftsmen prefer bolt compounds. This design is less reliable, but it allows you to easily remove and change the racks. The collapsible cutter is easier to clean from dirt and weeds wound on it.
One of the shortcomings of the “goose legs” is that during operation they are very buried, and this is not always necessary. There is an additional force on the engine engine, the operator gets tired. To reduce the deepening, wheels are installed on the axis on both sides, acting as limiters.
In this case, only the upper soil layer is cultivated. This method of processing is very convenient for strongly overgrown and skewed soils. After the first passage, sod is destroyed. Then the wheels are removed, repeated cultivation is carried out to the required depth.
If the “Goose legs” cutters are made with their own hands, the drawings are carefully thought out and the materials are correctly selected, then they are not inferior in quality to industrial.
Frasov. The main working “organ” of the cultivator. With its help, loosening, weeding, and preparation of the soil for planting are carried out. For mechanical models, as well as apparatuses of an ultra.Light and light category, it acts as a single functional element. In the installations of medium and heavy, trailer equipment is also used.
Motoboblock cutters: homemade, assembly
Do.It.Yourself milling cutters can be made at home without impressive material costs. Homemade cutters to the walk.Behind tractor are an integral element of this unit.
In some cases, it is necessary to install equipment for a large width and depth of soil processing on a motorbellum of Neva. To do this, the motor cultivator is equipped with factory cutters.
Motoboblock cutters. Purpose, features of use
The Neva model motor.Cultivator, like other analogues of such equipment, constructively consists of an internal combustion engine, which is mounted on a metal frame equipped with two wheels. The Neva Motoboblock handle is equipped with buttons for controlling the unit and attachment equipment.
The uniform tractor with an active cutter has a frame with an mounted trailer device. Attaching equipment is attached to the attachment of the Neva unit. Cutters for a walk.Behind tractor.
With the help of milling plants, subsequent soil processing is carried out. Treens for the Neva walk.Behind tractor affect:
- Quality of plowing;
- The convenience of controlling the unit during soil processing;
- Reliability of the transmission of the device;
- The efficiency of the power unit of the cultivator.
Homemade and factory cutters for the walk.Behind tractor (knives) are presented in the form of the main working body of the unit. Knives of the “Goose legs” type are intended for:
- Loosening of soil layers;
- Creating a certain structure of the processed soil layer;
- Weed fighting and their destruction during processing.
You can assemble the cutter to the walk.Behind tractor with your own hands, I have a minimum set of tools at hand. Housing paw knives are the most common milling option for a single tractor.
Other varieties of milling plants can significantly vary significantly in their form and device. Treens on the Unoa tractor modifications “Goose legs” differ from analogues by the number of cutting edges, their location and design.
- Milling cutters to motoblocks are considered the most important component of this unit, and the material from which they are made directly affects indicators such as the depth and quality of the treatment layer.
- This attachment equipment can be assembled independently, but it should be remembered that the highest quality mills to motor blocks are those that are made by forging with a self.Stroke.

You can assemble the cutter to the walk.Behind tractor using stamped metal sheets. Such cutters to the walk.Behind tractor will have an implicitly expressed cutting edge. In most cases, cutters for motoblocks like “Goose legs” are collected from stamped metal sheets.
“Methods of modernizing corner grinders with your own hands”.
Varieties of milling cutters. Active, goose legs
Motoblock mills can be of two varieties, these are:
Active knives are maximally adapted for all types of work performed. Their saber.Shaped form is considered the most popular, and it is quite simple to properly assemble them with your own hands.
- The effectiveness of active milling plants was confirmed by the results of use for decades and in most cases, cultivators are equipped with active (saber.Shaped) mills.
- For the manufacture of such attachments, high.Quality carbon steel with a high degree of strength is used.
- Active knives are distinguished by a collapsible design, the assembly and installation of products takes several minutes.
On the device and area of use of drilling and suction machines.
Steel used to create active milling cuts is completely unacceptable with welding, and to improve the mechanical strength of the products during production, the so.Called thermal cutter is used. To enhance strength, the finished product is subjected to high.Frequency current.
Relatively recently for walk.Behind engines, “Goose legs” mills began to be used. This modification is recommended to be used to process complex and solid soil types.
It is such suspension equipment that is used in difficult conditions of irregularities and rocky soils.
The design of such knives is solid, which directly increases the strength characteristics of the products. Mills are available with standard technical characteristics:
Such a tool has its drawbacks. Ordinary carbon steel does not differ in high strength characteristics. The knife must be subjected to regular inspection, especially when working on clay soils. To the menu
Features of the assembly of the milling cutter
Before the assembly of the blades begins, it is recommended to prepare a drawing of the future device in advance and get the necessary tools and materials.
If in the process of creation you need figured components, then it makes sense to order them from a wizard of blacksmithing.
Other structural elements are made independently. The assembly must be done correctly, focusing on the existing drawing.
If the assembly occurs incorrectly, then in the process of operation the unoic tractor can deviate from the movement line, which will make it difficult to cultivate the earth. Freze blades are inserted into special nests and attached with bolts.
At the same time, it is important to properly place the cutting line of the petal. It should be placed during the direction of movement and pierced the soil with a sharp end.
Cutting cutter for a motor cultivator
I process the soil of the garden and the garden manually, using a shovel. To process large plots, he used to invite a tractor with a plow. He plowed in the fall, lamb was in the spring, and for six years ago I was presented with a motor.Cultivator of the Kaliber Kovrovsky plant.
In the fall, under the garlic, on the plowed area, the soil was processed by a motorbike. In the spring, in an unnecessary section, the same.Based tractor began to stop from overload, although the depth of the plow (soil) 25 cm was indicated in the operating instructions. In the store, this indicator was correctly rejected, saying that this is a cultivator, not a plow. In order to loosen the soil deeper, it was decided to make its cutter with a capture width of 100 mm already than already from the existing one, in the occasion, I acquired 16 segmented knives from the Smolensk hay.Beam, which eventually turned out to be heavy for the motor.Cultivator. I had to cut the knives on the sides from the outside and two knives left and right with the internal. As a result, the unoic tractor began to pull well and delve into the soil without jumps and jumps. The height of the knives is limited by the engine pallet and is 160 mm, the depth of the soil reached 20 cm, while the soil processed on the site can be characterized as a heavy black soil. Loam. The design of the cutter is shown on the sketch.
A cutter knife consists of two parts of cooked: a vertical part of a steel sheet 5 mm thick and 50 mm wide, the horizontal part of the Don-1500 cereal segment is 2.5 mm thick and 76 mm wide wide. The horizontal knife is located at a vertical one at an angle of 30 degrees to the main plane, like a plow’s lime with a cultural dump. The cutting edges of the knives do not enter the axis of the coordinate (like cutting mills for metal processing), which ensures the optimal angle of soil loot (cutting angle). This is the main difference between my milling cutter for soil processing.
Later, the Unoa Tractor of the “Ugra” of the Kaluga plant was acquired. The cutter sold to the walk.Behind tractor, when processing the soil, throws a heavy unit and does not want to loosen the soil deeply, the knives and the cutter itself are made without taking into account the laws of cutting. Colleagues with a walk.Behind tractor recommended loading the unit with counterweights to increase the weight and depth of loosening, but this is an absurd solution and we went a different way, and it was my hair cutter, based on the previous experience. The results are very positive.
When processing in the spring of moisturized soil with segmented knives, the mills began to clog with dirt, the triangular ends had to be cut off with a corner grinder, the work of the cutter improved.
At a.With. Pushkin on this score is the words: “And the experience, the son of difficult mistakes, and genius, paradoxes friend, and case, God inventor. “”. Based on the experience gained, it can be recommended to the manufacturers to create a motorized motorist with a drive from an electric motor (in the likeness of electric shines), relatively light and compact, transported in the trunk of a car. The milling cutter itself deepens into the soil and pulls the gardener. The gardener, while the coupon disappears.
I can recommend that lovers of motoblocks and motor cultivators remake the milling cutters of the factory manufacturing, taking into account the rear part of the knives are on the coordinate axis, the knife must be straightened, the upper part is cut at an angle of 30 degrees and weld the segment from the coda. If desired, in the factory, or in the forge, you can make a knife for a milling cutter, Mr.
When hanging this type of knives on tractor cutters, we will have a pushing plow of a redpower with new capabilities: in terms of performance and quality of unauthorized soil processing.
Comparing the work of a motor cultivator and a walk.Behind tractor, we can say that a motor.Cultivator is easier, more convenient and maneuverable in management. The purpose of the walk.Behind tractor is wider, but control requires great efforts to them. A clutch cable at the handle often breaks off in a walk.Behind tractor. When working with a mowing, the fastening bolts weaken and require frequent overthrow, the knives of the braids quickly fail, for the 100 best products you could put a couple of extra sets of knives in SIPs. All this technique is not made for people, but for rationalizers and inventors: create, invent, try.
I would like to note that I will be glad if these proposals for modernizing mills will find the use of dachas and gardens from lovers and will not be left without attention among manufacturers.
How to assemble mills on a single tractor correctly?
The assembly of the cutter can cause some difficulties, especially if you do this for the first time and alone.
First you should familiarize yourself with the structure of the cutter.
The drawing below indicates its main components:
- Rotary axis (there are different lengths, can be solid and detachable);
- Finger with a latch;
- Knives (right and left);
- Structural elements (nuts, washers and bolts).
Also do not forget to take into account the fact that the movement of the knives during operation is directed counterclockwise. Be careful when assembling the module. Any deviation in the design will lead to the fact that the balancing of the axis will be violated, the unit will be entered during operation.
We also offer to familiarize yourself with the video that describes in detail about the process of assembling milling to the walk.Behind tractor:
Sharpening of a home.Made cutter
Do.It.Yourself soil.Graders must be sharpened. To do this, you need an angular grinder with a diamond circle, the diameter of which is 125 millimeters. Current machine is difficult to use due to the size and direction of the bending of knives. Small knives can be sharpened with fine.Grained sandpaper.
Rules for sharpening knives on home.Made equipment:
- Knives can be sharpened only at an angle of 45 °. Previously determined the side of the recess into the ground;
- No need to remove a lot of metal, 1-2 sharpening in the season is enough. The frequency of sharpening can change depending on the intensity of operation and the type of soil processed.
If the cultivator is often operated on wet soil, you need to control the condition of the milling. The formation of corrosion can be prevented if you use a special anti.Corrosion agent. You need to avoid cutting cutters on stones and other solid items. So the term of use of the equipment is extended, the need for frequent sharpening of the knives is reduced.
At the end of the work, soil.Graders should be cleaned of the ground, plants and other pollution. Use a rag or brush, various cleaners are not suitable. If the cutters are stored for a long time, the knives are lubricated with solidol, and for the ends of the shaft, they use graphite lubricant.
Homemade cutters can be installed on mole, centaur and many others.
Doing This Will Make Your Engine Run Better
Which mills are better for a walk.Behind tractor?
Such “knives” for soil processing can be divided into two large groups. Each of them has its own characteristics and is suitable for a certain type of work.
Saber.Shaped mill to a walk.Behind tractor
The most popular and universal models that are effective in performing various excavation works. These models use the optimal shape of the knives, for the manufacture of which manufacturers choose high.Quality durable steel.
The models have a collapsible design, so their installation and maintenance is as simple as possible.
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 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.
