How to correctly assemble (install) milling cutters “goose-feet” on a power tiller and whether it is necessary to sharpen them
Structurally, a tiller is a set of tillage blades placed on a rotating axle. This module consists of two parts, which are installed on the drive shafts on both sides of the power unit. Thanks to this arrangement, a single-axle tractor is able to move independently during cultivation.
One can also select the type of tillers with attached tillers, which rotational motion is ensured by PTO. The module is behind the power unit and does not participate in the movement. MTZ, Neva, Prorab, Sich, Agro motor units are produced in various modifications, with the PTO and without.
There is practically no difference in the construction of both mounted and conventional tillers. But for a power tiller with independent rotation, there is an additional module with a PTO drive and a double-sided angular reducer.
Blade blocks on such milling machines consist of four cutting elements spaced 90˚ apart. There can be 2, 3 or more such blocks on one side of the drive. The number of blades and module width depends on the weight of a power tiller and its power.
The blades are curved strips of solid alloyed steel. For self-made cutters with thermal treatment and subsequent hardening it is recommended to use spring steel 50ХГФА type. The blades alternate their angles.
The design of the active blades allows cultivation of stony or rooty areas without risk of scraping the blades. But it is reasonable to use this type of equipment on light workable soils.
The cutting elements of these burrs are made as a triangular-shaped, robust steel blade on the end of the leg. This arrangement is the reason for such an extravagant name.
As with active tillers, the width and number of blade assemblies are determined by the weight and power of the power tiller. Number of cutting elements arranged around the circumference of the blade assembly, 4 or more. blades means better crumbling of the ground but the power requirement of the power pack is higher.
A rotary mower for the tiller can be useful on a garden plot.
Both of these tillage machines are designed for heavy soils and fallow land. The presence of branched root systems in the soil leads to frequent blocking of the module.
Both tillage machines have advantages and disadvantages. When choosing the option for self-made, one should take into account the soil structure, the required degree of soil crushing, layout and power of the power unit, complexity and manufacturing techniques.

Such equipment as a tiller is essential for any power tiller, as it can be used to carry out most of the work associated with the treatment of the soil. Basically, a tiller comes with the unit, but in cases where you need to change the width and depth of processing, you should buy the equipment separately.
Additional cutters allow you to increase the functionality of the power tiller and simplify the work with it. Experts recommend having several pairs of cutters in your arsenal.
What cutters are better for a power tiller??
Such “knives” for tillage of the soil can be divided into two large groups. Each of them has its own features and is suitable for a certain type of work.
Sabre-shaped cutter to a power tiller
The most popular and versatile models, which are effective in carrying out various earthworks. These models use the optimal shape of blades, for the manufacture of which manufacturers choose high quality durable steel.
Models have a collapsible design, so their installation and maintenance is as simple as possible.
These models are relatively new on the market. With their help any virgin soil can be processed, they are also effective in the cultivation of hard and difficult soil. Features of cutters of this type:
Such models, unlike saber cutters, are made of carbon steel, which is a bit less durable.
Homemade tillers for power tillers
Manufacturers offer a variety of tillers for power tillers. You can use one set of tillers or buy two different types of devices, changing them depending on the soil processing conditions. Some craftsmen prefer to use homemade products, which, if properly assembled, will be no worse than the factory ones.
The main advantage of making a soil cutter yourself is that it can be adjusted to the specific features of the site.
How to assemble properly the cutters on a single axle tractor?
The tiller should be assembled correctly with your own hands. Again, it is very important to make sure that the active part of the machine cuts into the ground during operation. To do this, it is first recommended to study the drawings and then proceed to make the equipment.
The goosefoot nozzle is best suited for heavy soils. It can be used on different models of power tillers thanks to the variable hub variations. These models are easier to operate, but are prone to jerks and impacts when working in the soil. Active counterparts or factory-made products do not always cope with heavy soils. This is especially true for versions with Chinese knives, where the quality of the metal leaves much to be desired. Not only will it be difficult for the user to hold the machine in his hands, but the load on the gearbox will also increase significantly.
These cutters can be repaired by removing damaged parts and replacing them with new ones. over, it has a width of seizure lock. Additional pairs of cutters can be placed in a row at the operator’s request.
If you know beforehand that you need to work hard terrain, you either have to choose high-quality cutters from Ukraine and Poland, or look for other modifications.
As for spiral milling cutters, referred to as “tselina”, this design is all-welded, which is done precisely to increase its strength characteristics in operation. That’s why it withstands heavy loads. The only thing that the user may not like is the slowness of operation. But this is understandable: you won’t be able to speed up on a virgin soil, no matter how much you’d like it.
If you want to buy this particular version of the milling machines, it is important to consider another disadvantage. during cultivation, the soil will be pushed from the center to the edges. This will form a shallow furrow, which may later require leveling the land. In other respects spiral milling machines are considered to be more reliable machines compared to other analogs. They are robust, reliable and long-lasting. If you need quality soil treatment in a difficult area, they are the best help for the gardener.
A comparison of milling cutters awaits you in the following video.

Do the blades of the cultivator blades need sharpening??
Cultivators are used to make physical labor easier when working the land. They are driven by electric or gasoline engines, and act on the ground with a special tiller. Working elements of the latter are metal blades. When cultivating the soil, they plunge into the soil, loosening it. This causes damage to the cutting edges. From time to time the blades need to be resharpened. If you do it right, working with a power tiller will be more efficient.
Which tillers are better: Sabre or gooseneck tillers
To understand which cutters are better: the classic saber-shaped, or modern. goosefoot, consider the advantages and disadvantages of tools on the main criteria.
- Cultivation efficiency. With the same working width, the hubs of the gooseneck tillers have twice as many “legs” as their sabre-toothed counterpart.
- Functionality. While standard sabre milling cutters are designed for medium-density soils, the gooseneck milling cutters are effective for heavy, clayey soils. Another advantage of the latter is their gentle cultivation, which results in little damage to the root system of the plants grown.
- Working element material. The sabre milling cutters are made of high-carbon, hardened steel, which is an advantage of this model. The welded construction of goosefoot is made of ordinary carbon steel 3.
- Breakage and repair. The material from which the models under consideration are made, determines the susceptibility to mechanical damage. Goose-foot cutters often fly off “legs” when working on hard soils. Only a welding machine can fix this defect. Sabre-like cultivators, on the other hand, have a collapsible design, and if broken, the working elements can be easily replaced.
- Price. Buy goosefoot milling machines are much cheaper than their saber-like counterparts.
How to assemble tillers for a power tiller
The factory cutter is installed according to the assembly instructions. For convenient work, they use special 50 cm high X-shaped trestle made of wood. Single axle tractor mounted on coulter. The angle of inclination should be at least 45°. Place a trestle under the handlebar and remove the wheel.
When assembling the cutter, remember that the equipment consists of right and left parts, which are fastened so that when the equipment moves forward the knives with their cutting edges enter the ground. That is why this unit is attached in the direction of travel.
Before installing the tiller on a single-axle tractor with your own hands, you need to check that the grooves and holes on the blades and blades of the linkage correspond to each other in diameter. If the scheme of assembly is wrong, the motocultivator during operation will deviate from the chosen direction, the process of milling the cultivated surface will become difficult.
Cultivation of land is a necessary process in its processing. During it the soil is tilled, but without lifting the lower layer of soil. Cultivator, which is a technique for working the ground, goes over it to a predetermined depth, loosens the upper part, and then crumbles into small pieces.
This results in the levelling of the field. An additional benefit is the clearing of ingrown weeds. In addition, cultivation improves the flow of air into the ground, allows the soil to warm up more quickly, gain nutrients and retain moisture.
The presence of blades on the cultivator gives the ability to quickly, thoroughly plow different types of soil. With their help, it is possible to work the land, and then be satisfied with the following advantages:
- A high level of plowing quality;
- Comfortable conditions for driving the cultivator when processing the soil;
- High level of reliability of the transmission;
- High efficiency of the cultivator.
Several kinds of tillers are available. Each one is aimed at its intended purpose. They are mainly designed to loosen the soil, create a specific structure of the layer of soil, which is cultivated, as well as to combat weeds.
How to work properly with a power tiller. How to set the cultivator correctly?
In order to avoid burying the cultivator and a number of other common problems, the owner of the equipment must perform a number of actions to prepare and adjust it.
- First set the cultivator on a thick board, and remove the factory wheels. Instead of them, mount one set of tines on each left and right side. One set of cutters includes 8 cutting blades. this number of elements gives the best result in processing the ground;
- When positioning the blades, pay attention to the position of the blades. They should only point forward. The working part of each blade must not be sharp. Otherwise the cultivator will not move forward, but will start to dig into the ground. In addition, the sharp cutters will cut weed stalks, rather than winding and pulling them together with the roots;
- Next, it will be necessary to install a clevis, necessary for the installation of the coulter;
- The coulter is a bar with holes drilled in it. It is necessary for precise adjustment of the position of the cutters when cultivating the plot;
- To fix the coulter, it must be mounted in a clevis and secured with cotter pins and bushings. For this purpose, a second hole is selected. It is counted from the bottom of the coulter. So, the depth of cultivation will be 20 cm. It is quite enough for quality treatment of the soil and elimination of large weeds;
- To increase the depth of cultivation, the coulter must be lowered down, and attached to the shackle through the top hole of the element;
- To reduce the plowing depth, the coulter should be lifted up, and secured to the clevis through its lower hole.
Which tillers are best for a power tiller? How to Make a Homemade Cutter #8211 Single Axle Tractor
I made my single axle tractor thirty-three years ago. Long time ago? And it works. I have always respected one law: the worm is the master of the soil and must not be killed! the router speed should be as low as possible, the pitch as high as possible, the diameter and spacing as large as possible, and the number of levers as small as possible.
Nothing overcomes resistance like an arrowhead. That’s why the knives are shaped like lances. The legs are bent: the tiller works like a vertical planer. The arrow goes in the ground and almost does not stir it, just pushes it back a little. The pitch can be up to 15 cm. At the same time, the maximum depth.25 cm.
My single-axle tractor doesn’t work in layers: it always works in one pass on any soil.
One reader complained: “I have loam, no single-axle tractor can handle it!” That’s what I’d like to help people with.
I always sharpen the arrows before work, so the cutter chops even the roots of bushes, doing 20 to 500 rpm. Has three speeds. When I plow high grass (up to half a meter), I use a scraper so the plants don’t get wound up on the shaft.
You have to follow the safety rules when working with a power tiller. The engine is running and the fuel tank must not be filled. Make sure there are no large foreign objects on the ground. The single-axle tractor is also dangerous on sloping terrain. The engine is from a chainsaw.
On all branded power tillers, the crutch dangles. I have it rigidly mounted, and at the end of it #8211 is a rotating platter.
The power tiller has no reverse speed, I don’t need it. When I have to turn the tiller, I push the handles, the tiller gets rid of the ground and I can turn the single axle tractor in either direction, so I can do very fine work, which is especially important in the garden. The crutch can’t go deeper than the plowed layer, so it doesn’t tear the roots.
There’s one thing about my cutter: the angle of the arrow has to be guessed very accurately. It must not be too positive or too negative. The arrow should push the ground back just a little bit. And the crutch should be positioned so that only one of them does most of the work. My cutter doesn’t dangle on the shaft like all the brand ones do), so you can put a cleaner.
The process of assembling a power tiller
Two forms of knives are distinguished:
- Sharpened. “Petals” easily penetrate the soil without adhering to the surface. Less strain on the engine and less fuel consumption. But sharp blades do not remove weeds completely, they soon sprout again. With such canopies you need to work carefully so as not to damage the plants and for your own safety;
- With a semi-circular edge. are safe to use. But there is more resistance when ripping, the tillers are more likely to get stuck. Such knives for a cultivator cope with weeds more effectively.
There are two ways of attaching the “petals”:
- On rivets. The element is not dismountable. In this case, it is not very convenient to store and transport the device;
- With bolts. The part can be disassembled.
To assemble a power tiller it is important to observe the correct direction of rotation. the sharpened part of the tine should point in the direction of travel of the machine.
The number of sections is equal to the fixing plates: if they are in the same location, only three elements can be installed. If they will move, four or six sections should be mounted. The knives need to be pre-marked.
How the tiller is assembled?
- When installing the three-blade cutter, the first blade is fixed to the plate. it is not necessary to fully tighten the bolt at first. The two remaining blades are fastened to the opposite side of the plate;
- The right and left blades are attached to the four-blade and six-blade burrs alternately. In advance, it is worth dividing the “petals” into right and left;
- If necessary, an additional section is mounted with a pin;
- The structure is bolted down as rigidly as possible;
- At the end, a protective disc is attached to the shaft to protect the plants from damage.
