How to correctly install cutters on a power tiller
There is no concrete answer to this question. Everything depends on the individual characteristics of the power tiller, the soil and the criteria for use. For example, sharpening is not necessary for the processing of heavy soils with a solid tiller with a reinforced cutter. You will not see any tangible effect from this procedure, you will only waste time and effort.
For a lighter tiller with small tillers, sharpening is a good option to improve the quality of work. And there are some disadvantages. Sharpening only lasts for several hours, then the function has to be repeated, and this process is long and labor-consuming. Secondly, sharpened blades contribute to the crushing of the roots of weeds, and this in turn can only accelerate their reproduction.
If you do dare to sharpen the tiller, remove it from the power tiller, clean it from the ground. As much as possible carefully sharpen each cutting element with emery cloth so as not to destroy them.
READ Installing the Engine on a Mole Single Axle Tractor
There are two types of power tillers:
It is worth mentioning that there are four- and three-blade milling machines, but it has little effect on the result of work. This design feature is aimed at reducing engine load.
Deep tillage
When developing new areas, it is necessary to master the virgin soil. Usually it is abundantly overgrown with turf, perennial grasses and weeds. Cope with such areas with ordinary tools is quite difficult. Cultivation with deep tillage with layer turning is used more often. At the reverse plowing part of the layer is undercut, it is lifted and turned around its own axis. The result is that the soil from the first layer is pushed to the top. Weeds are not allowed to grow for a while. Cultivated plants get a head start.
Similar work is carried out in the autumn. Rhizomes of nettles, creeping wheat grass, dandelion and other weeds freeze in November-December, when the air temperature drops below.15.17 ⁰С (no stable snow cover yet). Later they lose their ability to grow.
Subsequently this method is used every autumn. After 2 4 years of autumn autumn autumn plowing weeds on the site are many times reduced.
Proponents of organic agriculture do not agree with this approach. But the experience of several centuries proves that only with such agro-technical measures it is possible to clear the territory from weeds. Otherwise we will have to use chemicals to control weeds.
- Wrap the soil layer and allow the plants to use substances for nutrition, which gradually shift to the lower horizons during the season. Such an operation reduces the salinity of the soil with mineral fertilizers, as well as reducing the amount of fertilizer applied;
- Aeration of lower soil layers promotes emergence of aerobic processes of decomposition of plant residues. Usually in the lower layers, the access of oxygen to the air is limited. Therefore conditions are created, when the decomposition of roots of rod type is prolonged for several years. Anaerobic processes (without air access) occur with slow accumulation of humus;
- Weed seeds can’t germinate because they are in the bottom layers of the soil when the topsoil is turned over. Roots left on the surface freeze out. As a result clogging of soils sharply decreases;
- Frozen clods of soil in winter crumble more easily in spring. A light, loose surface layer is formed in which cultivated plants can receive more abundant nutrition;
- The incorporation of organic material before ploughing allows the active decomposition of manure or green manure if it is sown after the main crops have been harvested.
Which tillers are best
The sabre nozzles are suitable for all soils. For areas with stones and large roots, it is recommended to use mounted mechanisms with high performance. The blades of the active tillers do not break because of the quality of the material used. The cutting elements are characterized by maximum reliability, robustness and long service life. Mills are installed on cultivators.
Goosefoot is characterized by high passability of milling machines on virgin, untouched by agricultural machinery, as a result of which the soil is easily and quickly processed, the ground lump is thoroughly crushed, mixed at a depth of 30-40 cm. They are suitable for stony and hard-ground cultivation, weed control, and are mounted on both power tillers and power tillers.
The disadvantage of the tool is less strength. During operation, the blades should be constantly inspected for damage and repaired. Goosefoot material is not as strong as alloyed or high-carbon steel, but is nonetheless well weldable. If the cutting elements break or crack, the product can be repaired at home with minimal effort. This is a decisive advantage when choosing a power tiller.
Which one is better?
Cutters for a power tiller are selected for each type of work and depending on the soil structure. The sabre cutters, by loosening the soil to a depth of up to 35 cm, lift weeds to the surface. At the same time, they do not cut them into small pieces, but reel them in and swath them. Than do not let them multiply. This results in coarser “shredding” of soil. But on dense or virgin soils, sabre blades don’t go into the ground well. Larger and curly weeds quickly wrap themselves around the working area and slow cultivation.
Goosefoot tillers are great for difficult soils and all kinds of weeds. However, because they cut them into pieces with a sharp edge, the weeds multiply. There is a variant of combined use. In the fall, go over the plot with these cutters, and in the spring and during the season, work with sabre cutters.
How to correctly assemble the cutters on the single axle tractor?
Assembling the tiller can be a bit of a challenge, especially if you do it for the first time and on your own.
To begin with, we should get acquainted with the structure of the cutter.
The drawing below shows its main constituent elements:
- Rotor axle (comes in different lengths, can be one-piece or split);
- pin with locking device;
- blades (right and left);
- elements of fixing the structure (nuts, washers and bolts).
Also, do not forget to take into account the fact that the movement of the blades during work is directed counterclockwise. Be careful when assembling the module. any deviation in the design will lead to the fact that the axle balance will be broken, the unit when working will be skidded to the side.
We also suggest reading the video, which describes in detail the process of assembling the cutters to the power tiller:
Do they need to sharpen??
There is no definite answer on whether to sharpen the knife or not. Gardeners have their own opinion, but it is also contradictory. According to their opinion the need for sharpening may depend on the type of soil to be worked. For example, if the soil is sandy or thorny, it is not necessary to sharpen the cultivator blade. If they cultivate virgin land, they often hear about the need to sharpen the blades. As for the manufacturers’ opinion, it clearly indicates that the cutters do not need sharpening.
Specialists note that the sharpening of cutters is accompanied by shredding of weeds. This favors their vegetative multiplication, but also requires that the blades must be resharpened.
Of course, the machine will work more effective for two or three hours, but after that the blades need to be dismantled and sharpened again. And this will require compliance with the rules of assembly, because after sharpening it will have to properly assemble the working unit, and this can not every gardener. As for a heavy motocultivator with quite powerful cutters, there is no need to sharpen. Apart from the fact that it takes a lot of effort and time, the user will hardly feel the effect.
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? It works. Adhered to one law: the worm in the ground is the master, and it can not be killed! You want the rotational speed of the power tiller to be as low as possible, the spacing of the spacers to be as large as possible, the diameter and distance between the spacers to be as large as possible, and the number of spacers to be as small as possible. Nothing overcomes resistance so easily as the arrowhead, so the blades are shaped like a spear. The legs are curved: the tiller works like a vertical plane cutter. The arrow goes into the ground and hardly stirs it, only pushes it back a little. The pitch can be up to 15 cm. The maximum depth of the.25 cm.
My single-axle tractor does not work in layers: it always manages in one pass and on any soil.
One reader complained: “I have loam, no single axle tractor will take!”That’s why I would like to help people.
I always sharpen the arrows before work, so the cutter chops even the roots of bushes, making from 20 to 500 rpm. It has three speeds. When plowing land with high grass (up to half a meter), a scraper is placed, so the plants are not wound up on the shaft.
You have to be on the safe side when working with a power tiller. You can not pour fuel into the tank when the engine is running. Make sure there are no large foreign objects on the ground. Also dangerous single axle tractor on areas with a high slope. The engine is from a chainsaw.
The crutch is loose on all commercially available power tillers. It is rigidly mounted on my machine and on the end of it there is a #8211 rotating plate.
The machine has no reverse speed, I don’t need it
When I need to turn, I push the handles, the tiller gets rid of the ground and I can turn the single axle tractor in any direction, so I can do very fine work, which is especially important in the garden. The crutch can’t go any deeper than the plowed layer, so it doesn’t tear the roots
There is one tricky thing about my tiller: the angle of the arrow has to be guessed very accurately. It shouldn’t be too positive or too negative. The arrow should push the ground back just a little bit. And the racks should be placed so that only one of them performs the main work. My cutter doesn’t dangle on the shaft like all the brand name ones do), so I can put a cleaner.

Is it necessary to sharpen rotary hoes on a power tiller??
Irrespective of their design, milling cutters are self-sharpening tools. In this regard, sharpening the cutting blades by the operator is not required, because it can only spoil the condition of the organs.
The only exception. it is very old cutters, which should be sharpened only when the quality of plowing the soil has significantly deteriorated.
In this case, the sharpening is done in this sequence:
- First you need to remove the equipment from the power tiller, clean it of dirt and degrease it;
- The sharpening will be done according to the factory markings that are clearly visible on the blades;
- Next, you need to prepare the tool. It is best to use an angle grinder for work, pre-equipped with a new sharpening wheel. If this nozzle is not available, you can use a trimming wheel, but the quality of sharpening the cutter with them will be a little worse;
- After that, you need to put the cleaned construction on a fixed horizontal surface;
- Then it will be necessary to make measurements of the factory sharpening, using a caliper for this purpose;
- During the further processing of the knives you need to constantly check their thickness, so as not to remove extra millimeters of metal;
- At the end you will need to turn on the angle grinder and sharpen the knives to the factory chamfer.
During self-sharpening, you need to allow time for them to cool down completely
It is important to remember that the metal under the action of the sharpening wheel quickly heats up. If you do not take breaks, it can lead to overheating and deformation of the steel.
How to assemble correctly the cutters on a single axle tractor?
Assembly of the cutter with your own hands should be carried out as correctly as possible. And here it is particularly important to make sure that the active part cuts into the ground during work. To do this, it is initially recommended to study the drawings, and then already proceed to the manufacture of equipment.
The following tools are required to create the cutters:
- Rotor axle of the required length. It can be split into two parts if you need to assemble the cutter from two units.
- Short axle.
- Gearbox with retainers.
- Left and right knives.
- Bolts, washers, nuts.
The assembly does not take more than an hour, but here it is important to install the knives in such a way that they do not interfere with the rotation.
- The long rotary axis is equipped with knives at an angle of 30 degrees.
- Four blades must be joined together on a single block by attaching them to the gearboxes.
- Then the correct construction is checked and all fasteners are tightened.
This design is very reliable and can withstand quite high loads.
Assembling an active milling cutter
Thanks to the simple technology of creation, this type of cutter is widespread. In it, the blades as well as the legs are a single element. It uses a solid piece of metal made of high-strength steel. The use of such units is considered safer, in comparison with goosefoot, and there is less risk of injury to humans during their use. Due to the consistent placement of the cutting elements, they enter the ground smoothly, without impact. The manufacturing process to the point of creating a pipe with a flange is completely similar to the “caterpillar legs”.
It is worth to consider in detail how knives are made. First, a strip of metal after heating is bent so that the length of the resulting curved part was no longer than 80 mm. Drilling of the fixing element is then carried out, as well as cooling of the workpiece. At the end, the element is hardened and mounted on a flange.
Self-made cutters for use on a power tiller require tools and the ability to work with them. In addition, it is necessary to make drawings of the created product and clearly adhere to them. Any deviations in the details can cause the future “goose legs” to work incorrectly.

Is it necessary to grind milling cutters on a single axle tractor?
All tillers are self-sharpening tools. They do not need to be resharpened, because this would only damage the structure. Only in some cases, if you have been using the tiller for a long time and see that it is not working properly, the blades can be sharpened.
The tiller is an important element of every machine. Self-made properly assembled cutters can be used on any modern power tillers, in particular on the Neva MB 1 and MB 2, MTZ and others. Such designs will help in processing the land and make the performance of agricultural tasks easier.
Saber-shaped models
Such elements are considered very durable and reliable due to the fact that only steel is used in the manufacturing process. In addition, such models boast a unique design that makes them resistant to any mechanical damage. Saber models are standard on most European and American-made power tillers. The effectiveness of such elements has been verified on sites with any type of soil, which distinguishes them from other models. High quality and durability of these cutters enables top class tillage.
The main characteristic of sabre knives is that they are made of carbon steel, which guarantees reliability of each element even after a year of use. In addition, the knives are subjected to special treatment and hardening by means of high-frequency currents, thanks to which they can boast an incredibly high durability.
Assembly Instructions
It is not difficult to install the cutter on a single-axle tractor, but it will have to be assembled beforehand, properly organizing the direction of rotation: the sharpened part must cut into the soil.
Attachment is made to the axle of the output shaft. You need a stopper for locking. Carry out the installation actions with your own hands is difficult enough. The best way is to use X-shaped braces, made of wood. As a rule, they are made about 50 cm high.
The single-axle tractor should be leaned on the coulter, then tilted somewhere at the level of forty-five degrees, put under the handlebars of the steering wheel of the trestle. Then it’s just a matter of removing the wheel.
Before you start assembling a cutter on a single axle tractor, you should think about its design, as well as the functions it should perform. To do this, it is important to look at similar products, using information in detail. Otherwise, the product will not do the work that is needed. And therefore, the action will be meaningless.
First you need to make at least a rough drawing, one of these is shown in the photo. On this basis, all the necessary components are selected. And then you need to act according to the drawing, assembling each part step by step. When the assembly of the tiller for the motor-block is done, it is necessary to test. This will allow you to immediately make adjustments to its design, if the result will deviate slightly from the intended.
