If the user purchased mills without assembly, they must be properly assembled. Today this is not difficult, since the buyer has not only a detailed instruction of the manufacturer, but also a wide range of video materials, which can be acquired on the Internet

When collecting the product, it is important to ensure that the active part of the unit enters the soil during operation. Side options are installed on both sides of the walk.behind tractor, they work from drive shafts and wheels

In this position, the cutter is the practical replacement of the wheel of the motor.cultivator, it is they who drive motor vehicles in motion.

Mills, the work of which is carried out due to the power selection shaft, are located behind the cultivator. They do not take part in the movement of the device.

To install the milling on the cultivator, it is necessary to use special wooden goats with a height of about 50 cm. Also, at the same time, the technique must not only be raised, but also covered on a couch, but also tilted at an angle of 45 degrees. Then the wheels are removed from the motor.cultivator and cutters are placed in this place. Further, special plates should be installed on the outer ends on both sides, due to which the course of the device will be smooth and stable.

Additional sections are set to the main ones due to the use of pins. The limiting metal disk is connected to the frame by means of bolts. In this case, the number of blades should be selected for the cultivator, based on its power. To collect cutting blades, it is permissible to use one or more axes

Gathering a cutter with four petals, it is important to consider the sequence of the right and left blades that are placed on the fastener

Preparation and installation of milling.

Complete the milling on the one.axine tractor can be like this: 16, 24 or 32 cutting plates. Which set to choose. completely depends on the type of soil on the site, as well as on the area of ​​the processed territory. If you have to cultivate a small area, it is not recommended to use more than 16 cutting plates for this. The kit is considered optimal, in which there are 8 plates from one and 8 plates on the other side. If you decide to use sets of 24 or 32 plates for small sections, this will significantly increase the load on the motor block engine, and, as a result, the operator will greatly tire.

The phase preparation stage is the correct assembly of sets of cutting plates. You must be completely sure that their cutting part is located in one direction.

In no case should the cutting parts of the cutter should be sharpened. If you sharpen them, then the roots of weeds will not rise to the surface of the processed soil. The root system will simply be cut off by a pointed mill and will remain in the ground. After some time, weeds will grow up in the same place, and cultivation will be absolutely meaningless.

It is worth saying that the sharpened mills are quite strongly increased by the load on the motor block engine.

Single Action Sickle Bar for Walk-Behind Tractor: Maintenance

Also, stringing the cutter negatively affects the given depth of the site processing. If you sharpen the mills, the unoic tractor when moving forward will burst into the soil from time to time. This is due to the fact that the sharpened cutters do not capture the ground, but cut. This leads to the fact that they begin to bury strongly into the ground to a depth of more than 30 centimeters.

So you finished assembling a set of milling. Now you can proceed to the next stage of preparing a walk.behind tractor. installing mills on it. You must carefully make sure that the direction of the cutting part of the plates is placed in the course of the movement of the walk.behind tractor forward. It is very important not to confuse left.sided and right.hand cutters and install them in their places.

Adjusting the depression of the coupon.

Sushnik is a mechanism for adjusting the depth of soil processing. It has several through holes that are placed at different heights in relation to each other. When installing a coupon in the holder, you need to fix it through a particular hole using the cobble.

The choice of the hole depends on the depth of the earth you need. If you want to install the minimum depth, then you should install the couch on the holder through the lower hole. The through holes that are located slightly higher are intended for deeper cultivation of the land plot.

What other factors should be paid to the correct and high.quality installation of a coupon? If on your land plot is a fairly heavy type of soil or shortly before cultivation you have brought organic fertilizers, then you do not need to deepen your sonnoon too much in the soil. In such cases, it is strongly recommended to install a couch through the first hole for not too deep processing. If you install it through the second and above the second hole, then when the earth cultivation will be exploded into it (exactly the same negative effect will occur as when pulling mills).

How to choose the right one.axle tractor?

Let’s summarize how to choose a single tractor correctly so that it copes with the tasks and not at the same time not to overpay money for it.

much, revolutions, walk, tractor

The same.based tractor can have useful functions that can greatly facilitate working with it:

  • By adjusting the steering wheel, you can install the motor block handle in a convenient position-adjusting up and down allows you to adjust it to the user’s growth, and to the left and right it sets the motor unit on the left or right;
  • By unlocking the differential, you can block the left or right wheel during rotation. This function is most often possessed by professional heavy motoblocks;
  • The start of the machine will help to facilitate an electric starter, which is very relevant for heavy devices with a diesel engine;
  • If there is an emergency engine stop, in dangerous situations (oil deficiency) it will be disconnected.

Imported motoblocks are much more expensive than domestic, but at the same time they need only high.quality fuel. 3. Domestic motoblocks have a lower price, and the quality of the fuel is not as “sensitive” as imported. But since their reliability is lower than that of imported analogues, they need a more frequent replacement of components.

How to plow correctly

When using a walk.behind tractor, you can choose two types of transmission: increased and reduced. When plowing the Earth, the lowered is chosen, and when processing by cultivating it, on the contrary, it is increased. To improve the quality of cultivation, it is necessary to force the working parts to rotate faster, that is, increase the speed of speed, including an increased speed mode. The more revolutions per unit of time make cutters, the better the earth is loosened. Increase in gears reduces the load level provided on the engine of the walk.behind tractor.

At the end of the processing of the first landing line, it is necessary to check the depth of cultivation. If it is sufficient, you can proceed to the next lane. When processing the second bed, it is necessary to focus on the fishing line for the trimmer left by the snoker. During operation, the walk.behind tractor does not cost to press the steering wheel and push the car forward: from this it can start to bury in the ground.

The structure of the processed soil depends on the type of milling cutter. After cultivation, the plot may consist of large or small lands. Working knives are saber.shaped and made in the form of goose legs.

Sable.shaped are made of durable carbon steel subjected to a thermal cutter during production. These are a standard type of type included in the factory set of motor blocks. Workers “sabers” quickly understand parts, so they are easy to operate.

“Goose paws” are created for complex land plots that are difficult to process. It is worth using them on virgin, rocky, hardened soils. The product has an inextricable metal structure that can be changed by welding.

To achieve maximum efficiency of cultivation, it is worth a preliminary loosening, plowing the site to a depth of 10 cm. After that, we processed with mills, deepening them by 15–25 cm.

Safety precautions

When using a walk.behind tractor, in order to avoid unpleasant and unforeseen consequences, it is necessary to follow the operating instructions. Should not be allowed to manage the technique of children. People who have no experience in cultivating a motorcycle unit are not worth doing work alone. When operating equipment, it is necessary to remove outsiders and animals from themselves. For cultivation, you need to wear closed clothes with long sleeves, long boots with a metal toe, gloves and protective glasses. Non.compliance with safety conditions threatens to break down the device or injuries.

While working with the tool, you need to ensure that the hands do not fall between the rotating cutters. It is worth watching the front and rear lever, one of which should remain lowered. Before changing the direction of the walk.behind tractor, that is, the transition from the front to the reverse, it is necessary to stop the rotation of the working canopies. When the technique works, you need to listen to the vibrations that the engine issues. Usually they indicate the presence of malfunctions that need to be eliminated.

If we cultivate the earth with cutters instead of plowing with a plow, then after the snow gathering it will be compacted and will require a new processing. The operation of technology on compacted soil after winter provides an increased load on a single tractor and complicates the task of cultivating land plots. The quality of the Earth’s cultivation, controllability of the walk.behind tractor, the effort and the load on the engine depends on the installation.

Preparation of a walk.behind tractor for the cultivation of the site

Step one. Installation of mills

For the cultivation of the soil on a single.based tractor, instead of transport wheels, it is necessary to install on a set of mills on the left and right side, as shown in photo 2 (cutters are installed on the right side). One set of milling includes eight knives. This amount and location of the knives on the axis gives the most effective result of soil processing.

Please note that when installing knives, the cutting part should be directed forward, in the direction of the motoblock movement. Pay attention to the fact that the working part of the knife should not be sharp, since in this case the unoic tractor will not move forward, but will constantly burst into the ground, since the cutters will not loosen the ground, ensuring the gearing with the soil, but simply cut it.

Step two. Installation of a coupon

In the photo 4, it is shown how the earring is installed on the uniform tractor, to which the couch is attached.

The photo 5 shows a coupon. What is it and why it is needed? Sushnik is a bar with vertically located holes, with the help of which we can adjust the deepening of the cutting cutter during the cultivation of the land.

We install the couch in the earring and fasten it using a sleeve and codes in the second hole (the countdown is carried out from the lower part of the coulter). When installing a coupon in this way, deepening the cutting cutter in the soil will be approximately 20 cm. This depth is enough for high.quality soil processing for the subsequent planting of cultivated plants on the land plot.

Walk-Behind Tractor Tows 1,600 Pounds

To change the depth of soil processing, the coupon can be attached to the earring as follows:

  • To increase the depth of the soil processing, we lower the boss down and fasten it to the earrings through the upper holes.
  • To reduce the depth of the soil processing, we raise up and fasten it to the earrings through the lower holes.

Mills and a coupon are installed and the same.based tractor is ready to work. To determine the quality of adjustment of the deepening of the milling cutting, it is necessary to perform the control line of the walk.behind tractor along the land and make sure that the uno.legged tractor works without load during cultivation and the depth of soil processing meets our requirements.

Cultivation of the site with a walk.behind tractor

To obtain high quality soil processing with cutters, you need to choose the correct speed limit. Typically, there are two programs to move the walk.behind tract:

Unlike plowing, when the soil cultivation, the unoic tractor should work at increased speed, so in this case it is necessary to choose an increased gear to increase the frequency of rotation of the milling.

The choice of increased gear reduces the load on the engine of the walk.behind tractor, and with an increase in the number of rotation of the milling cutting, the quality of the loosening of the soil increases significantly.

After passing the first strip, check the depth of soil processing. If the depth is satisfactory, then you can continue the cultivation of the land plot. The passage of the second strip must be performed so that the cutters go along the line left by the second.hand, since the unprocessed area of ​​the soil remains between the milling cutter cutter.

When performing work on the cultivation of the garden, you do not need to crush the steering wheel down, do not push the one.axine tractor forward. all this can lead to the fact that the unoic tractor will begin to explode into the ground.

Useful tips

In order to optimize the load and increase the duration of the cultivator service life, the width of the loosening is selected by a change in the number of hinged soil cutters.

Adjust the depth of the blade allows the customizable council. He performs all the work, no effort on the uniform tractor does not need to be applied. The steering wheel handle is slightly pressed to the ground, the coupon enters the soil more and slows down the course of technology, thereby increasing the depth of cultivation.

So that the gearbox does not rest against the unprocessed ground, the equipment is a little swing.

When working with the cultivator, the user must hold his back exactly, hands. at the level of the belt. This position of the body contributes to longer operation of the unit and will not harm health.

If the blades are dug after a long use, they must be sharpened with a corner grinder. For simplicity of maintenance, self.substituting knives are chosen. The type of soil has a great influence on the cutting edges. In wet or heavy land, knives wear out faster.

For more comfortable work and high.quality cultivation of soil, the frequency of rotation of the cutter for the console motor block should reach 275 rpm, the cultivator. 140 rpm.

If the mechanized equipment does not work well with the soil cutter, it is necessary to find out the cause of the malfunction and timely eliminate it. If it is impossible to carry out repairs, turn to specialists for help.

How to collect correctly

The quality and speed of soil processing depend on the correct installation of cutting elements. Before assembling the milling cutter, it is necessary to carefully inspect the elements included in the kit. On them we will see stamped letters L and R. This means “left” and “right”. In order not to get confused, we will lay them into 2 identical groups. Hubs on which knives are attached can be based on a round pipe or hexagon. It depends on what shaft the cultivator has.

On the one hand, there is a small ledge with a hole for Shplint and a landing place for the first link of the knives. Take one of the pennies. It will be located on the left, in the direction of movement. We collect the first link from the gearbox. The cutting edges are placed so that they make a circle counterclockwise. We put the right and left knives alternately. In the presence of 4 elements, 2 knives lie from below, 2-on them, from above. Where on the pennies a hole under the slap, the knife should lie above in front of the hole. Otherwise there will be difficulties with the installation and extraction of codes.

We fasten the element so that the base plate is between it and the gearbox. Otherwise, the knife may cling to the gear casing. When the first link is ready, the second is collected.

We look at any of the screwed knives, on the next plate we find such a position that the new knife looks in the same direction, but is shifted several degrees counterclockwise.

On the mounting plates, we have incisors from the same side as the first link. This is necessary to observe the same distance between them. Correctly collected milling cutter, if you look at it from the end, has a spiral. We collect the right cutter in the same way.

DIY speed increase

How to make your same.based tractor faster? It should be noted that we are talking about transport speed. The Unoa Tractor Neva MB-2, with certain modifications, can develop a speed of more than 20 km/h, however, if it does not have differential, then management is significantly complicated.

You can increase the speed in several ways, for example, put the wheels of a larger diameter or change the gear pair of a wheel reducer, placing 61 and 12 teeth 55 and 18 instead of standard gears, respectively. This method is quite complicated, but allows you to increase the initial speed by almost 2 times.

Some owners want one.time tractor to go at a speed of 40 km/h. It is possible to make such a modification, but it must be borne in mind that you get a large load on the gearbox, and it will be difficult to drive such a vehicle.


Classification of cutters for a walk.behind tract occurs according to several signs. So, at the location, they can be lateral and hinged. The former is installed on wheeled drive shafts on both sides relative to the power unit. With this placement, cutters play the role of wheels, setting one.time tractor in motion. The second method of placement involves their installation behind the walk.behind tractor and work from the power shaft. This location is most characteristic of most modern motoblocks, including such well.known brands as “virgin lands”, MTZ and “Neva”.

The second criterion for the classification of milling plants is their constructive performance. On this basis, 2 types are distinguished: saber.shaped (active) cutters and “goose legs”.

Sable.shaped mills

Are included in the basic equipment of the walk.behind tractor and are the most popular among farmers. Cutters have a collapsible design, which makes them installed, maintenance and transportation very convenient and simple. Active milling cutter is made in the form of a block, which includes four cutting mechanisms. located relative to each other at right angles. The knives are mounted using bolts, washers and nuts, and the number of blocks on each side of the drive can be 2-3 or more pieces. Welding in the manufacture of milling plants is not used. This is due to the special properties of high.carbon steel and its immunity to this method of combining.

With independent manufacture of saber-shaped mills, it is recommended to use spring heat-treated hardened steel brand 50-ggf

Hinged cutters “Goose paws”

These cutters have a solid non.graceful design, which differs in high strength and long service life. With their help, you can not only effectively process rocky and clay soils, but also fight small weeds, as well as produce deep loosening of the soil. Standard factory assemblies have rather compact dimensions: 38 cm in length, 41 in width and 38 in height, the weight of the structure is 16 kg.

With its name, this species owes the features of the design of the knives, which are presented in the form of pointed triangular plates. located on the edges of steel rods, and remotely resembling goose legs in their form. The number of cutting elements can be different-from 4 pieces in factory models and up to 8-10 in homemade samples.

With an increase in the number of knives, the quality of soil processing increases markedly, however, the load on the engine also becomes much larger. Therefore, with independent manufacture of noodles, it is necessary to take this fact into account and not overdo it. The maximum speed at which the one.axic tractor, equipped with cutters “goose legs”, is 5 km/h, which corresponds to the average velocity of an adult. In this regard, managing such a technique is quite convenient and comfortable. The material of the milling plant is low-carbon steel of medium density, due to which when working with problem soil, the knives are often susceptible to breakdowns and deformation.

Criterias of choice

Before proceeding with the purchase of milling plants on a single tractor, you need to correctly evaluate the operating conditions and the type of processed soils. So, if it is supposed to work in stony areas, it is better to purchase a saber.shaped model. Such equipment will be easier to cope with complex soils, and in the case of a breakdown it will be easier to repair. To do this, just unscrew the damaged knife, and put in its place a new.

If you plan to plow the virgin land, it is better to choose the cutter “Goose legs”. It is well suited for the cultivation of heavy soils, as well as for deep, up to 30-40 cm, plowing. However, for working with sod soils, the naked model is absolutely not suitable: the knives will wrap the grass and long roots, and the work will often stop.

For such cases, you need to put an exclusively saber.shaped mill.

The principle of the cultivator and its main advantages

Cultivator for a walk.behind tractor. an agricultural unit for loosening, moisture conservation, soil hilling without turning the upper layer.

Types of cultivators

Among the cultivators, the following types are distinguished:

For the Neva motornote, the basic package includes 6-8 phrases-cultivators with a diameter of 360 mm and a capture width of 1200 mm.


The same.based tractor from the cultivator is largely weighty and the presence of a power shaft. The cultivator is equipped only with milling cutters, and any attached and trailed equipment that corresponds to the characteristics of the equipment is aggregated to the walk.behind tractor.

Different engines are installed on cultivators-2-, 4-stroke gasoline, diesel and electric, operating from the network or built-in batteries. They are compact, but in terms of power are inferior to motors built into motoblocks.

How to make a cultivator for a walk.behind tractor

Before the manufacture of the cultivator to the walk.behind tractor with your own hands, it is necessary to treat all metal elements with a special anti.corrosion composition from premature appearance of rust after frequent contact with the ground.

Simple models can be performed without drawings. To make and correctly collect more complex devices, you need to plan the work, calculate the dimensions of the module and parts.

Homemade cultivator from a fork is a simple way to re.cross (alteration) products. For this, the teeth of the mechanism with a hammer are bent by the type of corkscrew and planted on the handle. As a handle, a stalk from a shovel is used. For fastening, use island.

Some masters manage to make a cultivator with their own hands from a bicycle frame with a wheel. Between 2 blocks of the base is welded or fastened with bolts of a steel rod. The head is mounted to the cross. For this design, it is recommended to take a medium.sized wheel.

In order to correctly assemble a disk cultivator and work correctly with cutters, it is necessary to design the diagrams of the nodes and individual details. Given the deformation of the discs, special regulatory nuts are used. Disks are welded to the bushings located on a rotating axis with brackets. On the bracket it is necessary to provide a ledge where the pipe will take place. The cultivator handle is attached to the pipe surface. cultivator knives

For the manufacture of knives for a cultivator with your own hands, you need to take alloy steel with a thickness of 0.5-0.8 cm. The triangular shape of the knives with a pointed angle is optimal in terms of effectiveness. The width of the knives should be selected within 5-9 cm. Too bulky knives create increased resistance, due to which they often break.

As cutting elements, you can use knives from a segment mower, which before installation on the cutter must be hardened. This option of knives is not suitable for processing virgin grounds.

DIY Cultivator mills: Goose legs

Before starting manufacture, you need to familiarize yourself with the drawings, calculate the number of segments and the total weight of the structure so as not to load a low.power unit. On a cutta mill for a cultivator in one segment, it is best to install 3 “paws” at 3 “.

Making cutters for a cultivator type of goose legs with your own hands consists of the following stages:

  • First you need to make an axis with flanges. As an axis, you can take a steel pipe with a section diameter of 2.5-3 cm. The flanges for attaching the “legs” are made of steel plates 5 mm thick, holes are drilled for fasteners, and welded to the axial pipe.
  • Make triangular knives (see. in the previous section) and racks. For racks, it is best to take metal strips of the same steel brand. The rib that will be in contact with the soil during operation, you can sharpen. A knife is welded to one end of the rack, and holes for fastening are drilled in the other.
  • Further, the obtained “paws” are connected to flanges using bolts or rivets. The milling cutter is ready, you can carry out the first installation.

Active cutter for a walk.behind tractor with your own hands

Before starting the manufacture of an active cutter for a walk.behind tractor with your own hands, you need to decide on the type and study the drawings of the most suitable structure for a specific soil.

If there are figures in the selected design, they can be ordered from a turner, the rest of the elements can be made independently.

Consider the features of the manufacture of active (saber.shaped) cutters for the walk.behind tractor. The dimensions of the working elements should be no more than 50 cm, which allows them to deepen 25 cm into the ground. this is enough for effective plowing. The width of the tool can be selected based on the distance between the rows on the site, the weight and power of the walk.behind tract.

  • steel pipe with a diameter of 4-5 cm;
  • springs from a car or strip of alloy steel for future knives at the rate of 3 blades per segment;
  • welding machine;
  • corner grinder;

The manufacturing process consists of the following stages:

  • To make lobed knives, strips of steel or sprinkles must be made the same in length, heat and bend each on one side by 90 °, the length of the bent part should be 60-80 mm.
  • To weld the knives to the pipe, placing them segmented, 4 knives from different sides of the axis. If you want to make a prefabricated design, make an axis with flanges similarly to an analogue previously considered.
  • Sharpen the blades from the side where they enter the ground. Sharpically sharpen the diamond circle, the angle of sharpening is 45 °, it must be strictly observed.
  • Install a ready.made active mill to the cultivator, test and adjust.

Flat cutter

A plane cutter on a single tractor with their own hands is made of a metal pipe with a diameter of 42 mm on the basis of drawings of individual elements. In the manufacture of blades, they are adjusted in size and bended at a given angle. Welding apparatus welded blades to the pipe. Planting milling is performed in a fully assembled state. When assembling the module, it is necessary to dock them with the coupling of the walk.behind tractor, when the launch is tested, adjust.

In order to optimize the load and increase the duration of the cultivator service life, the width of the loosening is selected by a change in the number of hinged soil cutters.

Adjust the depth of the blade allows the customizable council. He performs all the work, no effort on the uniform tractor does not need to be applied. The steering wheel handle is slightly pressed to the ground, the coupon enters the soil more and slows down the course of technology, thereby increasing the depth of cultivation.

So that the gearbox does not rest against the unprocessed ground, the equipment is a little swing.

When working with the cultivator, the user must hold his back exactly, hands. at the level of the belt. This position of the body contributes to longer operation of the unit and will not harm health.

If the blades are dug after a long use, they must be sharpened with a corner grinder. For simplicity of maintenance, self.substituting knives are chosen. The type of soil has a great influence on the cutting edges. In wet or heavy land, knives wear out faster.

For more comfortable work and high.quality cultivation of soil, the frequency of rotation of the cutter for the console motor block should reach 275 rpm, the cultivator. 140 rpm.

If the mechanized equipment does not work well with the soil cutter, it is necessary to find out the cause of the malfunction and timely eliminate it. If it is impossible to carry out repairs, turn to specialists for help.
