How to assemble cutters on a single axle tractor
Classification of cutters
Soil tiller is a soil knives, fixed on the axle, which, rotating around it during the movement of the power tiller, shred the soil and weeds. Cutter designs vary, so in order to choose the best option, it is worth to understand their varieties. First of all, cutters are classified according to the type of aggregation:
Side cutters, installed as an undercarriage, essentially replace the wheels and operate from their drive shafts. Thus, they both drive the machine and cultivate the soil at the same time.
Mounted milling machines differ in their rear location. they are installed behind the power tiller, work from the PTO and perform only the function of cultivation. Such milling machines are equipped with Neva (MB 1 and MB 2), Celina and some others.
In addition to the type of installation, tillers differ in types of blades:
In this video, we will consider cutters for a power tiller:
Active sabre blades
The name of the cutters is determined by their appearance. the knives are large and have an elongated curved shape. On this type of cutters there are several sets of four knives, arranged relative to each other at right angles.
There are usually two or more sets of blades on an axle. This rather powerful design of the equipment has high strength and copes well with the processing of heavy soils and virgin lands, not afraid of rocks, roots.
The “goosefoot blades”
“Goose legs” on a single–axle tractor. another variant of equipment, the name of which is also determined by the shape of the knives. triangular, similar to goose legs, and located at the ends of the racks of cutting elements. As in the previous variant, the number of knives determines the quality of cultivation and varies depending on the power of the machine.
There are three-row and four-row goosenecks with different axle diameters. Three-row tillers on the axle with a diameter of 25 mm are installed on power tillers Texas, Neva, Mole, Caiman, and four-row fit units of the brands Salyut, Farmer, Favorit. Equipment with 30 mm axis diameter can be combined with Cascade, Master Yard, some models of Neva power tillers and some others.
“Goosefoot”. power tillers, which show high efficiency in processing heavy, clay soils and virgin soil, but can get clogged when working in areas teeming with roots.
Mounting on a single-axle tractor
It may be difficult to lift the cultivator and fit the burrs on your own. To do this, you can make special stands with slots for the axis. They are convenient to use, but you have to carry them with you all the time. It is possible to use outside help, but not always the work is done by two people.
In the field, if we came on a power tiller and need to perform the installation of the tiller on the cultivator, we can put the removed wheels under the axle. If the single axle tractor is light, tilt it up with one hand resting on the coulter bar, and use the other hand to position the tines.
Set them on the shafts so that the spirals diverge from the center to the edges, the cutters are positioned on both sides synchronously. Do not interchange assembled units. On both, the cutting edges should rotate in the direction of the block. The wrong mounting will move the tiller, but the load on the engine will increase. burrs do not cut into the ground to the proper depth.
Cutter varieties for power tillers. active, goosefoot
Cutters for power tillers can be of two varieties, these are:
Active blades are best suited for all types of work. Their saber shape is considered the most popular, and correctly assemble them with your own hands is simple enough.
The effectiveness of active cutters has been confirmed by the results of use for dozens of years, and in most cases, cultivators are equipped with exactly active (saber-shaped) cutters.
This attachment is made from high quality carbon steel with a high degree of durability.
Active blades are characterized by a collapsible design, assembly and installation of products takes a few minutes.
The steel used to create active cutters is absolutely not compatible with welding, and to improve the mechanical strength of products, the manufacturing process uses the so-called quenching. To strengthen the strength of the finished product is subjected to high-frequency current treatment.
Relatively recently, goosefoot cutters have been used for power tillers. This modification is recommended for the treatment of difficult and hard types of soil.
It is this suspension equipment is used in difficult conditions of uneven and stony soils.
The construction of such knives is solid, which directly increases the strength characteristics of products. Cutters are available with standard specifications:
Such a tool also has its disadvantages. conventional carbon steel is not characterized by high strength characteristics. Cutters must be inspected regularly, especially if you work on clayey soils.
How to assemble cutters for a power tiller
Aurora motor blocks and power tillers, and in principle, like many other manufacturers, are supplied with cutters in a disassembled form. Often, for owners of new equipment is some problem with the assembly process of cutters. In this article we will describe how to assemble working milling cutters from parts of this constructor. For the Aurora machinery, depending on the model, the cutters are available on axes, two sizes. The diameter of the axis for light equipment is 23 mm, and 32 mm for heavy equipment.
Cutters for light power tillers and cultivators are assembled quite easily. To do this you must install the blades in the special mounting sockets and screw them on. Pay attention to the direction of the cutting edge of the blade. It must face the direction of travel of the power tiller. In addition, each blade is marked. If the letter quotRquot is shown, it means it is turned to the right side, respectively quotLquot to the left.
Each successive section is secured to the previous one by a pin, and locked by a pin. The cutting disc must be bolted. Depending on the power of the machine, the number of cutters will be different. Their number can be 24, 32 or 40.

The number of blades is also different and can be three or four per section. This is due to the number of attachment plates on the axle. If the cutter axis is straight and not offset to each other, the number of blades is three. For models with offset. four.
Fourblade cutters are assembled sequentially, one left, one right. It is easier to assemble cutters if you first divide left and right blades into two parts, for left and right cutters.

The three blades are assembled differently. The first blade is mounted on the axle and secured with a bolt. Later on, this bolt has to be removed to fix another blade. If the first one was mounted on the outside of the plate, the remaining two must be mounted from the inside of the mounting plate. For three-blade milling cutters the marking quotLquot and quotRquot are set separately for each side.
How to assemble the cutters on a single axle tractor
Tilling land is much easier under today’s conditions than it was half a century ago, for example. There are now many options for this. For example, convenient power tillers, which due to their compactness but versatility allow to solve various tasks on the treatment of even small plots of land. As a result, they have become very popular among farmers and dacha owners who work in the soil.
The single axle tractor itself is of little interest if it is not equipped with the necessary additional equipment. That’s the only way to get the most out of it. In this case, we will figure out how to assemble the cutters on a single-axle tractor with our own hands.
How to correctly assemble a cutter on a single axle tractor?
Assembly of a tiller can be somewhat tricky, especially if you do it for the first time and on your own.
The first thing to know is how a tiller works.
The drawing below shows its main constituent elements:

- Rotor axle (comes in different lengths, can be solid or split);
- Finger with locking device;
- Cutters (right and left);
- Construction fasteners (nuts, washers, and bolts).
Also remember that the blades move counterclockwise during operation. Be careful when assembling the module. at least any deviation in the design will lead to the fact that the balance of the axis will be broken, the unit when working will be brought to the side.
We also suggest you read. The first page of the brochures on which the assembly process of power tillers to a power tiller is thoroughly narrated:
Not so long ago, cutters, which were called “goose feet,” began to be used for power jigsaws. They have proven themselves well, are most often used for hard and difficult soils. It is such cutters are used when cultivation needs to be carried out in difficult conditions, on stony soils. The goosefoot design is made solid, which provides the highest durability of the equipment. Standard tillers are available in various sizes:
A gooseneck mill.
- The width of the blades is 41 cm;
- the length of the blades is 38 cm;
- the height of the construction is 38 cm;
- The weight of the machine is 16 kg;
- The allowable working speed of a motocultivator with these knives is 2-5 km/h.
What are the advantages of the goosefoot cutter, can you install it yourself? It is convenient for tillage, weed control. Other models can not cope with the work better. For stony and hard soils, the goosefoot mill is simply indispensable. It should be noted from the advantages that the steel is weldable in this case. If necessary, you can make repairs at home, and not to buy new blades, as it is costly.
This milling cutter type has disadvantages, too. The main drawback is that it is made with ordinary carbon steel. The strength of the construction itself is at a high level, but the material is slightly inferior to other varieties. This kind of milling machine should be regularly inspected when working on clay soils, when cultivating virgin lands. Cutter blades can be bent or simply broken. However, the repair is not too difficult, for a broken knife is usually used a welding machine, after which the place of the break is carefully polished.
It is necessary to work with two people when assembling the scheme, because the weight of the construction is considerable. It is important not to reverse the direction of the blades on the axle. When assembling, the sharpening must face toward the cultivated soil. To strengthen the cutter, use a stopper, it is placed on the output axis.
Types of cutters
The most common and popular type of milling cutters for motocultivators is considered to be the “goosefoot” knife model. They can be made by your own hands with a basic set of tools. It is recommended to use in the farm only those types that have been made by following the forging technology and have self-sharpening properties.
Blades differ in shape and working principle. For example, these “goosefoots” differ in the presence, location, and design of the cutting edges. The material from which the cutter is made plays an important role. The quality of the material determines the level of depth, as well as the quality of processing layers of the earth.
Let’s look at specific examples of cutter varieties:
Saber-shaped cutters are standard cutters for any power tiller. They are equipped with a factory-made machine. Most farmers use active sabre cutters. Among the advantages of this type are:
If the blades are factory-made, alloyed or high-carbon steel sheet is used as the material. It is thermally hardened, treated with high-frequency electric current. Cluster blades are not recommended for use.
If it is necessary to use a self-made tiller, it is recommended to use hardened, heat-treated steel. For example, XGFA structural spring steel 50.
The goosefoot saw appeared in 2000. Since then, the blades have become popular because of a number of useful qualities. They appear due to the special shape of the blades. If you look at them, they resemble goose feet, which is why they got their name. The construction itself is one-piece and is not dismountable.
Factory-made products are characterized by their static parameters. Among them, the standard sizes for blades look like this:
In this case, cultivator develops speed with working blades to 5 kilometers per hour. It is customary to make them of mild steel for working the soil. This allows the knives to be self-sharpening. So, with proper handling, they do not need to be sharpened at all.
With the help of “goose feet” people cultivate virgin land or other, difficult types of soil. Do not use these blades when working on ground that contains a lot of roots. Because of them, the system will constantly clog and delay work in the field.
Any company’s power tillers will have factory-mounted models. But it often happens that a farmer wants to increase the power of his cultivator. This is due to the need for deeper tillage. To reach the goal, it is possible to make the blades yourself. To do this, it is necessary to follow the technology exactly to get a good tool.
The easiest thing will be to make and assemble a sabre milling machine yourself. To do this, it is necessary to acquire a metal strip of high-strength steel, an angle grinder, additional tools for direct digging, a welding machine and a pipe of small size.
Usually farmers make homemade models for a preconceived purpose. Therefore, when sharpening them, it is important to choose the direction of the blades at once. This will give them useful properties in the form of increased power and quality when plowing.
Homemade models work much more efficiently. This sets them apart from their factory counterparts. Homemade blades have been widely used since Soviet times. Farmers of the time needed to develop more efficient methods of tilling the land. So they began to create models of cutters for cultivators according to their drawings.
The now-famous “goosefoot” is a model that resulted from homemade products. Using the drawings of the then craftsmen, manufacturers decided to start conveyor production of a new type of blades. Now, what was once assembled “by the people” is made at every milling cutter manufacturer’s plant on cultivators.
How to properly assemble tillers on a single axle tractor?
Assembling a tiller can cause some difficulties, especially if you do it for the first time and by yourself.
To begin with, we should familiarize ourselves with the structure of the tiller.
The drawing below shows its main constituent elements:
- rotary axle (comes in different lengths, can be one-piece and split);
- pin with a retainer;
- blades (right and left);
- elements fixing the structure (nuts, washers and bolts).
Also, do not forget to take into account the fact that the movement of the knives during work is 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 broken, the unit will be skidded sideways when working.
We also suggest reading the video, which describes in detail the process of assembling cutters to the power tiller:
These models appeared on the market relatively recently. They can be used to till any virgin land, and they are also effective in cultivating hard and difficult soil.
- the solid construction, which ensures a high degree of precision;
- The equipment is good at fighting weeds;
- ease of operation, the possibility of replacing parts at home.
Such models, unlike saber-shaped cutters, are made of carbon steel, which is slightly less durable.
