How to assemble a milling cutter for a walk-behind tractor
Nowadays, the process of cultivating the land takes much less time than it did half a century ago. Modern manufacturers of agricultural machinery offer a wide variety of all kinds of equipment designed to make the work of farmers and land owners automated. For example, a single-axle tractor is a kind of compact and multifunctional special equipment designed to solve various tasks related to the processing of small plots of land. The single-axle tractor itself is a basic unit, which is equipped with additional equipment. Further in this article we will figure out how to assemble a milling cutter for a walk-behind tractor and achieve the maximum level of its performance.
How to properly assemble milling cutters on a uniaxial tractor?
Assembling the cutter can be difficult, especially if you are doing it for 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 (it can be of different lengths, it can be one-piece and split);
- pin with a retainer;
- knives (right and left);
- structural fasteners (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 balance of the axis will be violated, the unit will skid to the side during operation.
We also offer you to get acquainted with the video, which tells in detail about the process of assembling cutters for the walk-behind tractor:
DIY cultivator: assembly instructions
To create a cultivator, you can use a chainsaw, starter, angle grinder or washing machine.
How to assemble a cultivator for a walk-behind tractor step by step instructions
From starter
It will not be difficult to create such a cultivator if a starter from a car is stored in the home arsenal. If there is such a need, then the shaft is slightly shortened in the future. It is also advisable to replace the front cover, having previously made many small holes in it (up to 5 mm in diameter) for the intake of air from the attached fan. The prepared starter is combined into a design with cutters. Then the almost finished device is installed on the most common working platform of the cultivator and tested.
From an angle grinder
A home-made cultivator from an angle grinder does not have much power, but nevertheless does a good job of weeding the area. an angle grinder in such a device acts as an electric drive. Everything else is taken from old non-working cultivators.
Important! A conventional angle grinder is capable of up to 600 rpm, so when creating a cultivator, a pulley with a V-belt strand is used for it, and not cutting wheels.
To a frame made or taken from an old cultivator, it is necessary to weld the suspension unit of an angle grinder, and so that the product can be connected to electricity, take an ordinary extension cord on a coil.
After the cultivating base is put together, you can try out the machine. The cutters of such an assembled device should produce 300 rpm.
From a chainsaw
The method of making a cultivator from a Druzhba chainsaw with your own hands has already proven itself for a long time. The principle of creation is quite simple. As a result, the equipment is lightweight, compact and reliable, with a very powerful engine. The speed is approximately 2.5 km / h and the power is 4 hp. with., which is quite pulling on a decent single-axle tractor.
So, the process of assembling a cultivator from a chainsaw does not differ much from the general collection mechanism, but it has its own nuances:
- The main shaft is equipped with a collar flange. In the future, this will allow you to attach bridge gearboxes without any problems.
- Asterisks (usually from “UAZ”) and a two-row chain are taken and installed on the future mechanism. Thanks to them, the distance from the gear bridge to the ground becomes an order of magnitude greater. The timing sprockets, unlike others, increase the distance to the ground by as much as 15 cm.
Active cutters
The active milling cutter consists of a set of four powerful blades set at 90 ° to each other. There can be from two or more such sets on one axis. The number of additional cutters, as well as the size of their knives, depends directly on the performance of the walk-behind tractor. The knives of this cutter are in the form of curved strips, bent alternately in different directions. Their design and strength allow you to safely handle virgin soil, as well as areas where stones and roots come across.
Cultivator cutters: types, purpose, choice, how to assemble
The choice of good equipment is an important factor for land improvement. The land is cultivated using a cultivator equipped with high quality cutters. To do this, you need to understand what it consists of and how not to make a mistake when acquiring it.
People are interested in the answer to the question of how to assemble cutters on their own. Having devoted only 10 minutes of their time, the reader will receive useful information in the field of production, selection, and evaluation of the quality of the cultivator cutter. In addition, he will receive useful advice on the production of good blades, recommendations for the choice of materials for production, as well as criteria for evaluating the quality of equipment. Separately considered the question of how to assemble the cutters yourself.
Appointment
Land cultivation is a necessary process when cultivating it. During it, plowing takes place, but without lifting the lower layer of soil. The cultivator, which is a land cultivation technique, passes through it to a predetermined depth, loosens the upper section, and then crumbles it into small pieces.
This leads to the alignment of the field. An additional benefit is clearing the soil from ingrown weeds. In addition, cultivation improves the flow of air into the ground, allows it to warm up faster, gain nutrients, and hold back moisture.
The presence of knives on the cultivator gives the ability to quickly, thoroughly plow various types of soil. With their help, you can cultivate the land, and then be content with the following advantages:
- A high level of plowing quality;
- Comfortable conditions for controlling the cultivator during soil cultivation;
- High level of transmission reliability;
- Great efficiency of the cultivator.
There are several types of cutters. Each is aimed at its intended purpose. They are mainly intended for loosening the soil, creating a specific structure of the soil layer that is being cultivated, as well as for combating weeds.
Homemade milling cutters for walk-behind tractor
Motoblocks of any company will have factory-installed models. But it often happens that the farmer wants to increase the power of his cultivator. This is due to the need for deeper cultivation of the land. To achieve the goal, it is possible to make knives yourself. To do this, you need to follow the technology exactly to get a good tool.
The easiest way will be to make and assemble a saber cutter yourself. To do this, you need to acquire a metal strip of high-strength steel, an angle grinder, additional tools for direct digging of soil, a welding machine and a small pipe.
Usually, farmers make homemade models for a pre-planned purpose. Therefore, when sharpening them, it is important to immediately choose the direction of the blades. This will give them the beneficial properties of increased power and quality when plowing.
Homemade models work much more efficiently. This sets them apart from their factory counterparts. Homemade knives began to be widely used back in the days of the USSR. Farmers of that time needed to develop more efficient methods of cultivating the land. Therefore, they began to create models of cutters for cultivators according to their drawings.

The now famous “crow’s feet” is a model that is the result of homemade products. Using the drawings of the then craftsmen, the manufacturers decided to start the conveyor production of new types of blades. Now, what was once collected “among the people” is produced at each plant of the manufacturer of milling cutters for cultivators.
Types of cutters
The most widespread and popular type of milling cutters for a motor cultivator is considered to be the model of “crow’s feet” knives. They can be made with your own hands using a basic set of tools. It is recommended to use on the farm only those types that were made by observing the forging technology and have self-sharpening properties.
Knives differ in their shape and operating principle. For example, these “crow’s feet” are distinguished by the presence, location, design of cutting edges. The material from which the cutter is made plays an important role. The level of depth depends on the quality of the material, as well as the quality of processing of the layers of the earth.
Consider specific examples of types of cutters:
- Crow’s feet;
- Saber.
Saber organs
Saber cutters are standard cutters for any walk-behind tractor. The factory unit is equipped with them. Most farmers use active saber cutters. Among the advantages of this type are:
- Easy to install;
- Ease;
- Transportation comfort;
- Availability for repair.
If the blades are manufactured at the factory, then the material is alloyed or high carbon steel sheet. It undergoes thermal quenching, processed by high frequency electric current. Bush knives are not recommended for use.
If it becomes necessary to use a home-made cutter, then it is recommended to take hardened, heat-treated steel. For example, structural spring steel 50 KhGFA.
Do I need to sharpen the cutters on the cultivator
The question of sharpening knives on a cultivator has an ambiguous answer. Factory models are made using a special technology, using self-sharpening material. This avoids the need for manual knife sharpening.
These knives are mounted on crow’s feet. Because of this, they do not need sharpening if the equipment is used correctly. When deciding on the sharpening issue, it is worth starting from the specified table.
| Special purpose | Sharpening | Result |
| For working on heavy soil types with the powerful cultivator | Not | The sharpening field will not increase the effect. Therefore there is no need. |
| For cultivating small plots of land with a light cultivator | Yes | Improves the quality of land cultivation. |
Important: sharpening the cutter on light cultivators gives good results. But, after a few hours of productive work, the blades have to be sharpened again. In addition, sharpened knives crush roots from weeds, which leads to even more overgrowth.
How to assemble the right cutters on a uniaxial tractor
A walk-behind tractor is equipment that is indispensable in agriculture. It is aimed at performing agricultural work. To collect the knives on the cultivator and prepare it for tillage, you need to perform some actions.
First, you need to familiarize yourself with the cultivator for which the cutter will be manufactured. It is necessary to study its design. This will save time and assemble the finished unit. It will be most convenient to collect either saber knives or crow’s feet.
Studying the design of the walk-behind tractor, you need to pay attention to:
- Cultivator power;
- The upper frame of the walk-behind tractor, on which the fuel tank and engine are located. They will be mounted on adapted brackets;
- Equipping a walk-behind tractor or engine with a clutch and a gearbox.
The cultivator consists of the following elements:
- Short, rotor axis;
- Rotor axles of various lengths, assembled in two parts;
- “Finger” with a lock;
- Knives (right and left);
- Bolts and other parts for fastening 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 knives each. Each block employs 3 dedicated 4-blade assemblies. They are mounted strictly at an angle of 90 degrees. To create one knife, take a sheet of steel with a thickness of no more than 5 millimeters.
To make the racks, a steel corner with a size of 63×40 millimeters is taken. The knives are attached to the post and the other end is welded to the flange. This will combine 4 blades into one solid installation. Then the whole rig is interspersed with bolts.
If you follow these instructions, you get a solid and reliable structure that can easily withstand most of the loads. For regular use of the equipment, it is recommended to resort to using factory models rather than homemade knives. This helps the installation to run productively without interruptions and problems.
Crow’s feet
Hinged mechanisms called “crow’s feet” are used relatively recently. High efficiency is achieved due to their specific shape. The design of the cutters is all-welded and non-separable. The knives are made in the form of a triangle located at the end of the rack.
Factory standard cutters have the following dimensions:
- knife width. 41 cm;
- cutting length. 38 cm;
- gun height. 38 cm;
- weight. 16 kg;
- nominal working speed of the cultivator with cutters. 2-5 km / h.
Low carbon steel is chosen for the manufacture of soil tools. Self-sharpening knives, with careful use they can not be sharpened.
Active saber
The standard set of motor vehicles includes saber cutters. They are effective and popular with farmers.
The tiller for the walk-behind tractor has a collapsible design, so installation, maintenance, repair and transportation are as simple as possible.
Instead of wheels, blocks are installed on the rotating axle, consisting of 4 cutting mechanisms at an angle of 90 ° to each other, fastened with bolts, nuts and washers. The number of blocks on each side of the drive is different: 2, 3 or more units. The number of knives and the width of the module is influenced by the mass of equipment and its power.
The knife of an active milling cutter for a walk-behind tractor is a strip curved at the ends. The folds are directed alternately in different directions.
In the factory, the blades are made from durable alloy or high-carbon steel with mandatory thermal hardening and high-frequency treatment. When making the nozzle yourself, the craftsmen recommend using heat-treated and hardened spring steel 50HGFA.
Which cutters are better
The saber type is suitable for all types of soil. For areas with stones and large roots, it is recommended to use hinged mechanisms with high performance. In active cutters, the knives do not break due to the high-quality material of manufacture. Cutting elements are characterized by maximum reliability, strength and durability. Milling cutters are installed on cultivators.
Crow’s feet are distinguished by a large passability of the cutter on virgin soil, untouched by agricultural machinery, as a result of which the soil is easily and quickly processed, the earthen ball is thoroughly crushed, mixed at a depth of 30-40 cm.They are convenient for cultivating the land of stony and hard types, weed control and are installed both for motor-cultivators and walk-behind tractors.
The disadvantage of the tool is less durability. During operation, the knives must be constantly inspected for damage and repaired. The material of crow’s feet does not have such high strength characteristics as alloy or high-carbon steel, but nevertheless lends itself well to welding processes. If the cutting elements break or crack, the product can be repaired at home with minimal cost. This quality is the main advantage when choosing a milling cutter.
Types of cultivators
- with passive, or fixed, knives;
- with active, or driven, knives.
- manual;
- mechanized;
- aggregated with a tractor.
Among cultivators, the following types are distinguished:
- with disc cutters;
- with lancet paws;
- ploughshare;
- with rotary cutters;
- mulchers;
- chisels.
For the Neva walk-behind tractor, the basic package includes 6-8 milling cutters with a diameter of 360 mm and a working width of 1200 mm.

Home-made and factory cutters for a walk-behind tractor (knives) are presented in the form of the main working body of the unit. Houndstooth knives are intended for:
- loosening of soil layers;
- creating a certain structure of the cultivated soil layer;
- weed control and destruction during processing.
You can assemble a milling cutter for a walk-behind tractor with your own hands, I have a minimum set of tools at hand. Houndstooth knives are the most common version of the milling cutter for a uniaxial tractor.
Other types of milling cutters for walk-behind tractors can differ significantly in their shape and structure. Milling cutters for a uniaxial tractor of the “crow’s feet” modification differ from analogues in the number of cutting edges, their location and design.
HOW TO ASSEMBLE GRASS CUTTER WITH TILLER CULTIVATOR ATTACHMENT
Milling cutters for walk-behind tractors 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 soil layer.
This attachment can be assembled independently, but it should be remembered that the most high-quality cutters for walk-behind tractors are those that are made by forging with self-sharpening.
You can assemble the cutter to the walk-behind tractor using stamped metal sheets. Such cutters for the walk-behind tractor will have an implicitly pronounced cutting edge. In most cases, cutters for walk-behind tractors are assembled from stamped metal sheets.

How to sharpen a homemade cutter correctly?
Manufacturers of motor cultivators supply equipment with already sharpened standard cutters for sale. However, what should a person who has made cutters for an existing cultivator do on their own? In this case, you will need to sharpen the cutting knives of the device yourself.
To sharpen the equipment, you will need an angle grinder equipped with a diamond wheel with a diameter of 12.5 cm. Otherwise, you can use a grinder, but it will be difficult to use it due to the size and direction of bending of the knives. If the manufactured cutters are equipped with small-sized knives, then for their quick sharpening, you can use fine-grained sandpaper.
It is necessary to sharpen the knives of a homemade cultivator cutter strictly at an angle of 45 °. In this case, it is necessary to independently determine the side that goes deeper into the soil. It is not required to remove too much metal from the knife; 1-2 sharpenings per season are quite enough. In some cases, the frequency of sharpening the cutter knives may vary. it all depends on the intensity of use and the type of soil being processed.
Assembling the cultivator cutter. the correct procedure
Making accessories for a cultivator with your own hands makes it possible to adjust the width that the structure will cover, for certain features of the existing site. Before assembling the cutter on a motor cultivator,
you will need to prepare the following materials:
- a steel tube, approximately 4.2 cm in diameter;
- metal parts that can be sharpened and further used for plowing the soil;
- welding machine;
- angle grinder.
Also, to assemble the device, you will need springs from an old car or leftovers from other existing equipment.
Further manufacturing algorithm is as follows:
- First, the parts taken for plowing the soil must be adjusted in size. in the future they will serve as blades for the cutter;
- Next, bend the blades in one specific direction;
- Then weld the finished blades to the pipe so that they are located on different sides of the existing axis;
- Sharpen the edges of the blades in the direction that will correspond to their movement;
- The cutter made must be attached to the existing cultivator. Installation of the structure is carried out by means of the coupling mechanism of the unit:
- If you are making additional cutters for the existing standard equipment of the motor cultivator, then you need to connect them not with the coupling device, but with the axis of the standard cutters. In this case, bolts are used for fastening.
Types of milling cutters for a motor cultivator. varieties and description
All cultivator cutters available on the market lend themselves to a specific classification.
The following types of equipment are found on the market:
- cutters equipped with saber knives. devices of this type are considered the most popular among buyers. The high efficiency and productivity of such structures has been proven for several decades and by a lot of satisfied farmers. The main advantages of such cutters include their optimal shape, material of manufacture and methods of their processing. They have a collapsible design that allows you to quickly replace a broken part. Today almost every Kraftsman, Neva and Hyundai cultivator is equipped with saber cutters;
- cutters of the type “crow’s feet”. equipment of this type has come into active use relatively recently. Such devices cope well with the processing of hard types of soils, virgin lands with the simultaneous removal of tall weeds. The high strength and reliability of the cutters was achieved due to their non-separable design. The main disadvantage of such devices is the material from which they are made. for most of the “crow’s feet” cutters, manufacturers use carbon steel, which is much easier to deform when plowing heavy clay soils. However, crow’s feet tillers are fairly easy to repair and weld. Equipment of this type is now included in the package of cultivators manufactured by Caiman, Oka, Avangard and Cascade.
When choosing milling cutters for a cultivator, be sure to take into account the type of cultivated soil. The efficiency and duration of the practical use of the selected equipment depends on this.
How to make homemade cultivator cutters with your own hands?
Before starting the manufacture of the device, you will need to finally decide on the most suitable type for specific conditions in order to take into account the design features during the assembly process.
Having chosen the type of fixture, you need to carefully study the drawings, in which you will find the installation procedure and the method of fastening the cutter parts. Then you will need to prepare the materials and equipment required for manufacturing.
During the manufacturing process, great attention must be paid to the correct assembly sequence. In case of an error, the finished cutter will pull the cultivator to one side or the other.
Most experts agree that the dimensions of the parts of a home-made cutter for a cultivator should not exceed 50 cm.This cutter can go deep into the ground at a distance of up to 26 cm, which is more than enough for effective plowing of the area.
It should also be noted that the saber-type cutter is safer for the farmer in the event that he accidentally falls on the structure. In addition, the knives for the cultivator in such a device are placed alternately, so that they enter the ground without impacts and jerks.
To use the active cutter as long as possible, it is extremely important to adhere to the rules of its operation. Each time the tiller is switched on again, the tiller must be positioned above the soil level. Starting the speed, the blades of the device should be slowly deepened into the ground and begin plowing the area.
