Types of attachments
The main motivation when buying any power tiller is to cultivate the ground. This task was given maximum attention by the designers.
The list of attachments available for sale includes:
- ridger (a kind of plough with V-shaped or disc-shaped ploughshare);
- potato digger;
- potato planter;
The evolution of plowing devices was embodied in the following types of devices:
- standard plough. Wide blade. a ploughshare of such a device loosens the ground during plowing, undercutting the roots of weeds. The bent sheet. the moldboard turns the ground layer.
The way a standard plow is attached to a power tiller is illustrated in the figure The main parts of this device: ploughshare, mouldboard, stand, heel, field board can be seen in the figure
- Reversible (rotary, double-rotary) plough. Two plows are mounted on common frame at 90 or 180 degrees. Shafts of them are directed in different directions. In the working position, one plows the ground while the other is at the side. After traversing furrow change places by pushing (or removing) the latch and turning to the side. It spares the operator from having to return to the beginning of the field every time, making a half-travel.

- Zykov plough. Improved version of classic plough. Differs from it by changed geometry of ploughshare and moldboard surface. Thanks to tweaking, it is good for turning over soil layer and crumbling it.
In two-turn version and complete with ridge, wheel, and hitch bracket (price in 2018 17-18k. )
Developed and produced in Ukraine, Zykov plough is still rare in Russia. Only some self-made enthusiasts try to reproduce it in home workshops.
Earth turned over with plough. “semi-finished product”, which requires finishing. A harrow is used for this work, which breaks up large clods and levels the soil.
There are two kinds of harrows:
It should be noted that disk harrows perform better and cleaner than toothed harrows.
This type of attachment for power tillers is designed for loosening the soil and making furrows when seeding, planting seedlings and weeding.
By design, the harrows are:
Single-row, fixed-width (25-30 cm) planters are designed to work with lightweight tillers (up to 4 l.с.). Variable width of working and double-row installation allows to use these devices on more powerful machines and handle different width of seedbeds.
Two-row power tillers on reinforced frame (average price 2.5-3 thousand. )
Disc coulter (average cost of 3 to 4 ths. )
Rotary (propeller) tillers do not require the use of a hitch, as they are placed instead of the wheels of the tiller. Specially shaped serrated discs loosen soil and pull weeds between rows.

They can perform several operations:
A set with a power tiller usually includes universal cutters with sabre-shaped blades. They are easy to work on soft ground. Machines called “goose-feet” are used for dense, overgrown weeds.
High mechanical strength and a special shape of rotary tillers allows you to loosen neglected areas, pulling out weeds with the roots. In autumn, they are used to kill insects and pests, buried in the ground for the winter.
Potato planter and potato digger
Potatoes, the main crop of our fields and summer cottages, requires significant labor input during planting and harvesting. To mechanize these operations two attached units are used: potato planter and potato digger.
The first is equipped with a small plow that makes a groove. There is a hopper on the frame immediately behind, from which the potatoes fall at regular intervals into the ground. Two hinged pick-up discs attached to the rear of the frame cover the seedbed. In this way three operations can be carried out in one pass.

Anyone who has shoveled potatoes at least once will certainly appreciate the usefulness of this simple device. Potato harrow fixed on coupling of a power tiller consists of a plough with welded steel bars. Lifting the soil under the bushes, it gently lifts the tubers to the surface. After this operation, it is easy to put them in a sack or a box.
Beside fan ones, there are more efficient vibratory diggers of the screen type. They are designed for large areas. The connection of such equipment is made through the PTO, which transmits torque to the pulley of the potato plow, causing the working elements of the mechanism to vibrate.
Vibrating potato harvester (for these devices start at 12 thousand on average). )
Mowing grass is another important work operation performed by attachments.
There are two types of mowers for power tillers:
Rotary design is easier to maintain. The segment mower resembles a barber’s barber. It is more complicated in design, but cuts the grass cleaner than a rotary mower. This attachment is used for mowing large lawns.
Rotary mower, average price 14-20 thousand, depending on the model.
In addition to purely farming implements, power tillers are aggregated with other devices:
Work on the plot of land and on the territory of the homestead is associated with the transportation of fertilizers and forage, crops and firewood. These problems can be solved with a cart-trailer. It turns a single-axle tractor into a “short-range vehicle.
A useful option that some types of motor-block trailers are equipped with is a dump body, which facilitates unloading.
Useful addition to a motorized tractor that gives it the functions of a mini-tractor. A good adapter saves the owner the trouble of walking around the site.
By design, adapters can be rudderless (only the seat, linkage lever and brake) and equipped with a rudder.
Such a simple machine makes land cultivation easier and sells for an average price of 10,000 or more
The handlebar adapter is several times more expensive. But it is more than its price if you consider its performance capabilities.
Grader, mini-tractor, dump truck, and plowing machine. The functions of four mechanisms are combined by a steering adapter with a complete set (cost about 32 000 )
Many owners do not park their single-axle tractor in winter. It can be used to shovel snow off large areas of the property. Snowplowing devices, aggregated with it, can be divided into several groups:
The simplest and most affordable is the moldboard-type device. The width of the shovel, which is fixed to the front of the power tiller, can be from 0.8 to 1.5 meters. Its size depends on the motor power. The blade is designed to adjust the tilt and swivel angle.
Where the shovel is helpless, which is often the case with high snow drifts, the rotary snow blower gets the job done. It connects to the power take-off shaft of the power tiller. Screw rotor design has a high performance and confidently cleans the area of snow up to 50 cm in height.
Brush attachment is used to clean areas with expensive decorative surfaces that require the most accurate work.
For watering plots located far from power lines and close to water bodies are created motor pumps. This attachment for power tillers is connected to the universal joint shaft. The average pump capacity is 20-40 m3 of liquid per hour. The generated head is up to 4-5 meters with a suction depth of up to 10 meters.
To optimize the machine’s workload and service life, the loosening width is adjusted by changing the number of tools on the machine.
Adjustment of the working depth is made possible by the adjustable coulter bar. It does all the work, no force is needed on the single-axle tractor. The handlebar is pressed lightly against the ground, the coulter is pushed in firmly and brakes the machine, increasing the cultivation depth.
The machine is rocked back slightly so that the gearbox does not sink into the uncultivated ground.
When working with the cultivator, the user should keep his or her back straight and the hands at waist level. This body position allows the implement to be operated for longer and in a healthier way.
If blades get blunt after a long time of use, they need to be sharpened with an angle grinder. Self-sharpening blades for easy service. Soil type has a big influence on the cutting edges. Cutters wear out quicker in wet or heavy soil.
For more comfortable work and high-quality cultivation of the ground, the rotational speed of the tiller for a cantilever motoblock should reach 275 rpm, for a cultivator. 140 rpm.
If mechanized equipment does not work well with the tiller, it is necessary to find out the cause of the malfunction and correct it in time. If it is impossible to carry out repairs, ask for help from specialists.
Goosefoot tillers for power tillers
To give more strength to the cutters, they are made of steel, all-welded and non-disassembled. Such cutters are called. goose-foot cutters for power tillers. They are used successfully and efficiently in hard soil. They fit almost any tiller or single-axle tractor.
The main thing is to make sure that the axle diameter is right. Goosefoot tillers are great for hard ground to plow “under the potatoes”. They are also used for preventing garden pests (wireworm or Colorado potato beetle) or for quickly plowing a garden.
They divide goosefoot tillers into 3 and 4 rows. If the axis diameter is 25 mm, 3-row burrs are used for power tillers Texas, Mole, Caiman, Neva, and 4-row ones are used for power tillers Farmer, Salut, Favorit. If the diameter of the axis 30 mm 4-row tillers are used for power tillers Kaskad, Pubert, Master Yard, Neva.
How to assemble power tillers correctly and whether or not to sharpen them
Soil tiller for power tillers is one of the main components. Cultivator performs its main functions with its help: loosens the soil and gets rid of weeds. This part consists of a rotating axis with blades attached to it. Usually such accessories come with the machine, but many recommend buying or making some additional cutters for the power tiller yourself. It will allow to change depth of plowing and width of cultivated surface.
How to assemble tillers for a power tiller
Mobilizers and power tillers from Aurora, and in principle, like many other manufacturers, are supplied with disassembled rotary hoe blades. 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 construction kit. For Aurora machinery, depending on the model, cutters are available on axles, two sizes. axle diameter for light equipment is 23 mm, for heavy equipment. 32 mm.
Cutters for light power tillers and cultivators are easy enough to assemble. To do this, install the blades in special mounting sockets and screw them down. Attention must be paid to the direction of the blade’s cutting edge. It should look in the direction of movement of the power block. In addition, each blade has a marking. If there is a quotRquot, it means it is turned to the right, respectively quotLquot to the left.
Each successive section is locked to the previous one by a pin, and locked by a pin. Cut-off saw blade must be secured by a bolt. 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 can also be different and can be three or four per section. This is determined by the number of blades on the axle. If cutter axis is straight, without offset relatively to each other, the number of blades will be three. For models with offsets. four.
Four-blade cutters are assembled in series, one left, one right. It is easier to assemble the cutters if you first divide the left and right blades into two parts, for the left and right cutters.
The three blades are assembled differently. The first blade is installed on the axle and is fixed with a bolt. In the future, this bolt will have to be removed in order to fix another blade. If the first was mounted on the outside of the plate, the remaining two must be mounted on the inside of the attachment plate. For three-blade cutters, the quotLquot and quotRquot markings are set separately for each side.
How to properly sharpen
If having weighed all the arguments for and against the sharpening of cutters, the meaning of this procedure has not lost its relevance, it is necessary to deal with the way of performing the task.
The experience of supporters of sharp cutting surfaces of attachments of power tillers allows to allocate some key steps of work:
- All attachment sections must be removed from the power tiller and disconnected. After that, unscrew the bolts fixing the cutting elements from the body.
- Clean any dirt from the intended sharpening points.
- With the help of an angle grinder of small diameter, equipped with a grinding wheel to make a rough correction of the cutting elements by leveling the obvious irregularities of the metal. For the convenience of work, an angle grinder should be used with a small diameter. The optimal choice would be 115 or 125 mm.
- Grind the blade directly at an angle of 450, trying to remove as little metal from the blade as possible. There is no point in trying to achieve perfect sharpness.
- Assemble all parts of the equipment and install them on a single-axle tractor.
It should be noted that the described procedure is relevant only for the saber milling machines. The principle of operation of the goosefoot and “virgin sanding” devices differs from the variant under consideration. There is no need to sharpen them. Thus, fundamentally deciding whether there is a need for sharpening power tillers, the described procedure will help to make the most comfortable and effective use of the working tool.
The most common and popular type of cutters for motocultivators is considered to be the “goosefoot” knife model. They can be made by your own hands with a basic tool kit. It is recommended to use in the farm only those types that have been made by following the technology of forging and have the properties of self-sharpening.
Blades differ in shape and working principle. For example, the specified “goosefoot blades” differ in the presence, location, design of the cutting edges. The material used to make the cutter plays an important role. Depending on the quality of the material depends on the depth level, as well as the quality of the processing of layers of land.
Let’s look at specific examples of cutter varieties:
Sabre-shaped blades are standard on all power tillers. They are used in the factory. Most farmers use active saber-shaped cutters. Among the advantages of this type stand out:
If the blades are made in a factory, alloyed or high-carbon steel sheet is used as a material. It undergoes thermal hardening, processed by electric current of high frequency. Blades from cluster production are not recommended.
If there is a need to use a homemade cutter, it is recommended to take hardened, heat-treated steel. For example, structural spring steel 50 XGFA.
Goosefoot appeared in the 2000s. Since then, the knives have become popular because of a number of useful qualities. They appear because of the special shape of the blades. If you look at them, they resemble a goose’s 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 knives look like this:
At the same time, the cultivator develops speed with working blades up to 5 kilometers per hour. For work with soil, it is customary to make them from mild steel. This allows the knives to have self-sharpening properties. So, if they are used properly, they need not be sharpened at all.
With the help of “goose feet” people work virgin land or other, difficult types of land. It is not recommended to use these blades on land that contains a lot of roots. Because of them, the system will constantly be clogged 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 caused by the need for deeper tillage. To achieve the goal, it is possible to make the blades yourself. To do this, you need to follow the technology exactly to get a good tool.
The easiest way to make and assemble a sabre cutter yourself. To do this, you need to acquire a metal strip of high-strength steel, an angle grinder, additional tools for digging directly into the ground, a welding machine and a small-sized pipe.
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 gives 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-made counterparts. Homemade knives began to be widely used back in Soviet times. Farmers at that time needed to develop more efficient methods of working the land. That’s why they began to create models of milling cutters for cultivators according to their drawings.
The now-famous “goosefoot” is a model that resulted from homemade products. Using the drawings of the craftsmen of the time, manufacturers decided to start conveyor production of the new type of blades. Now, what was once assembled “by the people” is made in every factory by the manufacturer of cutters for cultivators.
By location of the cutters there are lateral and hinged cutters. Lateral ones are installed on both sides of a single-axle tractor, working from the drive shafts of the wheels. In fact, with this arrangement, these cutters replace the wheels and drive the machinery.
The second type. a power take-off shaft-operated cutter is located at the rear of the machine and does not participate in the movement. Motobloks of the brands Celina, Neva MB-1 and MB-2, MTZ have exactly such a device of mills.
By the design of blades there are two types of milling cutters. saber (active, standard) and the so-called goose-foot.
The active tiller consists of a set of four powerful blades set at a 90° angle in relation to each other. There can be two or more such sets on one axle. The number and size of additional blades depends on the power unit’s output. blades of this mill are in the shape of curved strips, bent alternately in different directions. Their design and ruggedness allow you to safely handle virgin land, as well as areas where there are stones and roots.
The second design type of cutters. goosefoot. It gets its name from the unusual shape of the cutting elements, which resemble the claws of a goose. They are shaped like a triangle and are located on the edges of the tines. The number and size of blades also depends on the power of the power tiller. The more tines with blades. the better the workmanship.
This unit can work hard, virgin and clayey soils, but will most likely get clogged if there is excessive vegetation and roots.
Cultivator cutter assembly process
There are two forms of blades:
- Sharpened. “Petals” easily enter the soil without grip. This reduces the strain on the engine and lowers consumption of fuel. But sharp blades can not completely remove weeds, 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 characterized by safety in operation. But there is more resistance when ripping, the tillers are more likely to get stuck. Weeds are dealt with more effectively with these cultivator blades.
There are two ways of attaching the “petals”:
- On rivets. One piece is not removable. In this case, it is not very convenient to store and transport the device;
- On the bolts. The part can be dismantled.
To assemble a cutter on a power tiller, it is important to observe the direction. the sharpened part of the “petal” must be placed in the direction of movement of the machine.
Number of sections equal to fixing plates: if they are all the same, only three elements can be installed. If they will shift, four or six sections should be attached. The blades must be marked beforehand.
How the tiller is assembled?
- When mounting a three-blade burier, the first blade is fixed to the plate. the bolt does not need to be fully tightened at first. The two remaining knives are attached to the opposite side of the plate;
- On the four-blade and six-blade cutter, the right and left blades are alternately mounted. It is worth dividing the “blades” into right and left blades in advance;
- If necessary, an additional section is mounted with a pin;
- The construction is bolted down as rigidly as possible;
- At the end, a protective disc is attached to the shaft to protect the plants from damage.
