Cultivator (power tiller) cutters
Cutters for a power tiller are simple enough to make yourself, without the need for large financial outlay. They are usually already part of the machine, but are not always available in the right width. The equipment made by our own hands. a great way to get the right-sized tools. Let’s study the types of milling machines, the peculiarities of their self-made and installation on the cultivator.
Making a rotary tiller for a power tiller with your own hands
The drawing of the Goose-feet rotary cutter shows the design of the rotary cutter for power tillers. The segment of the rotary cutter consists of three beams (legs of the feet) arranged at an angle of 120° in relation to each other. The beam length is given in the drawing as 100 mm, but if you use a stiff material for a mill, for example, a metal angle or plate with thickness of 5 mm or more, the length can be increased to 200-250 mm, especially if the mill is made for a large heavy power tiller. There is no point in making longer legs. If you increase the length of the beam, you must accordingly increase all other dimensions of the rotary cutter drawing, multiplying them by the coefficient of increase, the value of which you get by dividing the new length by the old one. Important condition for easy and productive work rotary tiller is leg location itself on the foot, namely the angle of 11 ° to the perpendicular of the beam cutter. This angle ensures the minimum resistance of the tiller during the plunge cutter penetration. This affords highest possible rotary cutter efficiency and lowers the power requirement for the tiller’s high performance drive, i.e. it speeds up the tiller’s work in a very short time.е. the engine will run with less load (which is important for a two-stroke motor), and the single-axle tractor will not bounce. Feet of rotary tiller for motor-block in most cases are made in a triangular shape (lancet tiller) and sharpened on an emery. Three-beam segment is bolted or welded to the rotary cutter drive shaft, which is made of pipe with diameter of 33 mm or more, with wall thickness of at least 6-8 mm. Bolt-on mounting of the cutter beams enables quick repair and sharpening of the gooseneck blades. Usually there are 8 segments on the shaft, 4 on each half axle, with a distance between them of 10 to 20 cm, depending on the length of the legs and the size of the feet

Classification of tillers
Soil tiller is a soil blades fixed on the axle, which, rotating around it during the motion of the power tiller, chops the soil and weeds. The milling machines are differently designed. To find the best choice, it is worth sorting out the different models. First of all, tillers are classified according to the type of aggregation:
Outboard tillers, installed as a running gear, essentially replace the wheels and work from their drive shafts. So they both drive the machine and cultivate the soil at the same time.
Rear-mounted tillers. mounted on the back of a power tiller, powered by the PTO and working only as cultivators. Such cutters are used in Neva (MB 1 and MB 2), Celina and some others.
In addition to the type of installation, power tillers also differ in the type of blades:
In this video, let’s look at cutters for the power tiller:
Active saber-shaped
The name of the cutters is determined by their appearance. the knives are large and have an elongated curved shape. On this type of milling cutters there are several sets of four blades, located relative to each other at right angles.
Usually there are two or more sets of knives on one axis. This fairly powerful equipment design has a high strength and copes well with the processing of heavy soils and virgin lands, not afraid of the rocks, roots.
“Goosefoots.”
“Goose legs” on a single-axle tractor. another variant of equipment, the name of which is also determined by the shape of the blades. triangular, goose-foot-like, and located at the ends of the cutter posts. As in the previous version, the number of blades 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, Krot, Caiman, and four-row fit units of the brands Salyut, Farmer, Favorit. The equipment on the axis of 30 mm is combined with devices Cascade, Master Yard, some models of power tillers Neva and a number of others.
“Goose feet”. tillers for power tillers, which show high efficiency when processing heavy, clay soils and virgin soil, but can be clogged when working on areas abundant with roots.
What other tillers for power tillers are available?
Two types of units (saber legs and “Goose legs”) are the most popular nowadays. Deciding what cutters are better for a power tiller, saber or “goose feet”, farmers prefer both, as they have different capabilities and functions. Sabre cutters are standard equipment and are used to cultivate the ground. They are time-tested. They are made of high quality steel. To increase the density of the metal, it is hardened and treated with an electric current. The sabre mills are prefabricated and bolted, since this type of steel does not react to welding.

The single-axle tractor is a true all-rounder, and makes an excellent assistant for the farmer who has not yet reached the size when he needs to buy a tractor. In addition, the single axle tractor is much more compact. Depending on the attached equipment, it can replace many separate units, saving the owner a lot of money. The cutter is one of the most important types of “attachment”. Therefore, many owners puzzle over how to assemble the cutters on a single-axle tractor and how difficult it is to do on their own.
Which tillers are best for a power tiller??
Each type of rotary hoe has its own strengths and weaknesses. When choosing a tiller for a power tiller, you should consider its power, as well as the operating conditions.
For example, a sabre blade tiller is very robust thanks to its design and the material from which it is made. This type of tiller has integral blades, and it is made of high-carbon hardened steel. It has universal functionality, because it can work in all conditions and on different soils. It is also easy to repair the blades, just insert and fix a new cutting element.
The goosefoot tiller is also good for heavy tillage and cultivation, but areas with sod or roots will be difficult to overcome. The equipment will get clogged and perform poorly on them. Also, due to the peculiarities of its design, it is more prone to breakdowns, and repairs are usually made with welding work, which is longer and unprofitable.
As you can see, each of the power harrow kits is not without its advantages. Choosing the right one depends on the technical features of your power tiller and the type of work to be done.
Goose-foot tillers for tillers with power tillers
For added strength, gooseneck planers are made of steel, fully welded and indestructible. Such tillers are called goose-foot tillers for power tillers. They are used successfully and effectively on hard ground. They are mounted on almost any power tiller or single axle tractor.
The main thing is to make sure that the axis diameter is right. Cutters goose-feet are great if you have a hard surface to plow it into potatoes. They are also used for preventive maintenance against garden pests (wireworm or Colorado potato beetle) or for quick plowing of the vegetable garden.
The gooseneck milling machines can be either 3- or 4-row. If the axis diameter is 25 mm, 3-row rotary tillers are used for Texas, Mole, Caiman, Neva motocultivators, and 4-row are used for power tillers Farmer, Salut, Favorit. If the axle diameter is 30 mm, 4-row tillers are used for power tillers Kaskad, Pubert, Master Yard, Neva.
Making a rotary cutter for a power tiller with your own hands
The drawing of the cutter “Goose-foot” shows the design of the rotary rotary cutter element for the tiller for the power tiller. The segment of a rotary cutter consists of three beams (legs) positioned at an angle of 120° in relation to one another. The beam length is indicated in the drawing as 100 mm, but if you use a rigid material for the milling cutter, such as metal angle or plate with a thickness of 5 mm or more, the length can be increased to 200-250 mm, particularly if the cutter is made for a large heavy power tiller. There is no point in making longer legs. If you increase the length of the beam, you must correspondingly increase all other dimensions of the rotary cutter drawing by multiplying them by the increase factor, the value of which you get by dividing the new length by the old. Important condition for easy and productive work rotary tiller is the position of foot itself on the foot, namely the angle of 11 ° to the perpendicular of the beam. This angle makes the resistance of the soil during tiller plunge. This means the rotary tiller’s efficiency is as high as possible, and the power required for the tiller’s highquality drive is reduced, i.e.е. the engine will work with less load (which is important for a two-stroke engine), and the single-axle tractor will not “bounce”. the tines of a rotary tiller for a power tiller are often made in a triangular shape (lancet tiller) and ground on an emery table. three-beam segment is fixed by bolts or welding to the rotary cutter’s drive shaft, which is made of 33 mm or more in diameter and wall thickness of at least 6-8 mm. Bolt-on cutter beams allow for quick repairs and goosefoot sharpening. Usually there are 8 segments on the shaft, 4 on each half-axis with a distance between them of 10 to 20 cm, depending on the length of the legs and the size of the feet
Selection rules
To the choice of the attachment “goose feet” should be approached with the utmost responsibility, because it depends on this, whether the model is suitable for working the land on your garden plot. In the process of selecting, first of all, you need to pay attention to the size of the nozzle. The element should be chosen so that its diameter fully corresponds to the size of the planting shaft. The peculiarity of the latter is that they have three rows of knives. The gooseneck tines are well suited for Texas or NeVa series power tillers.
In addition, in the process of buying goosefoot cutters, you need to carefully study the outer diameter of the element. This is an extremely important indicator, because it has a direct impact on the ploughing depth.
Of course, the quality of the blades is also important. If it is the Chinese cheap knockoffs, then after the first treatment they will start to bend and break. It is best to give preference to models that use carbon steel during the production.
