How to assemble a tiller on a single-axle tractor farmer
On power tillers with a PTO shaft, the tiller set can be a separate attachment. The unit is rotated by a belt drive. The machine moves by wheels or grousers. The single-axle tractor itself moves slowly, while the cutting unit rotates at a frequency of at least 3,000 rpm. In this case, we can say that it is an active milling machine, referring to the type of its feed.
On light tillers and power tillers, the cutting elements are mounted instead of wheels. They rotate and cut the soil and move the machine at the same time. The milling unit is a passive feed and is therefore called a passive milling unit.
It is not quite correct to call a tiller “active” or “passive” just because of its design features. Active sabre elements offer the best compromise between quality and performance. They are made of alloy steel. Hardened and subjected to HF currents at the factory. They do not require additional service and are perfect for all types of terrain.
Tines are usually assembled in links on hubs, 3 or 4 at a time. Each link is offset at a small angle to the next. Their curved ends are alternately turned in different directions. As practice has shown, 3 elements in a link do not give a stable movement of the machine. The construction is bouncing and hard to control. That’s why it is better to buy tillers with 4 blades. Working width depends on the engine power of the power tiller. It varies from 0,8 m to 1,2 m.
Farmers try to make sabre-shaped tillers with their own hands. Even if you can find steel from the springs, then there is a problem with giving them a curved shape. This requires machining in the forge, welding is not an option.
Another good thing for gardeners and farmers is to equip their cultivators with a goose-foot tiller. Originally, they were made by craftsmen, but now they are available in stores. The design has its own advantages:
- a welded device made of suitable material;
- Sharp cutting blades;
- the ability to replace any of the worn out elements.
Such assemblies are used when it is necessary to process virgin land. Thanks to the high rotation speed, they can cope not only with sod-podzolic soils near Moscow, but also with the soil of the black earth regions of Russia. Sharpened edges, which enter the layer at an acute angle, loosen and mix the fertile layer. With goosefoot tillers there is no need to re-cultivate the site.
How to assemble a tiller for a power tiller
the single axle tractor is a popular tool on the farm. Assembling a tiller for a power tiller is an important moment in preparing to till the land. The most common cutters are sabre-shaped blades (image ), as well as devices called goosefoots (image ). These attachments are easy to assemble on a power tiller. They perform most of the agricultural work on the plot. They only need to be changed very seldom. This significantly reduces the time spent on servicing the power tiller.
What cutters are better for a power tiller?
Such “knives” for tillage can be divided into two large groups. Each of them has its own characteristics and is suitable for a particular type of work.
Sabre-shaped power tiller
The most popular and versatile models that are effective for performing various earthworks. These models use the optimal shape of blades, for the manufacture of which manufacturers choose high-quality, durable steel.
The models have a collapsible design, so their installation and maintenance is as simple as possible.
Cutters for a cultivator (motor cultivator)
Cutters for a power tiller are easy enough to make on their own, with little financial outlay. As a rule, they are already present in the set of agricultural equipment, but not always this attribute has a suitable width for processing. The equipment made by your own hands is a great way to get the right-sized tool. Let’s study the types of mills, the peculiarities of their independent production and installation on the cultivator.
Assembling an active tiller for a water cooled diesel power tiller
The active tiller for the Garden Scout GS81D(E)-GS101D(E)-12DE water-cooled diesel power tillers, as well as for mini tractors based on the power tiller comes disassembled, unless otherwise specified in advance. The tiller is used for milling the soil.
A person who has not encountered the assembly of a tiller, it is quite difficult to quickly understand the assembly. It takes about 45 minutes to assemble the tiller, and we offer you a manual (instruction) with photos, according to which you can easily assemble the tiller of your power tiller:
The first stage of assembly is the installation of the blades in the appropriate mounts on the hub. Place hubs with cup points facing each other, position blades in such a way that the sharpened side of the blade goes into the ground as it rotates.
The first to install is the blade that is closest to the dust cover (which is mounted on the gearbox). The sharpened part of the blade must face the movement of the cutter and its curved part must face the gearbox.
Install the other blades in a similar way to the first one. The second step is to prepare the gearbox: a thrust block is mounted to the lower part of the gearbox and bolted on.
Also mount the screw for tensioning the gearbox chain, it is installed in the center of the gearbox, between the stop and the pinion gear.
Next, mount the hubs with knives on the reduction gear. On the hub, near the dust cap is a fixing bolt, which should align with the hole on the splined shaft of the gearbox.
Next, the stud bolts are inserted into the hubs and properly screwed into the gearbox shaft.
The studs additionally fix the hubs to the gearbox shaft.
Fitting the undercarriage: On the undercarriage fit and bolt the undercarriage guard in the shape of a mudguard. Screw the fixing beam to the casing.
Put a cowl on the gearbox and fasten it with bolts.
An inseparable part of the tiller is a wheel, which is used to set the cultivation depth and fix the seat-adapter (if it is included in the delivery set). Wheel fork is mounted on the hitch beam of the power tiller and the wheel height adjustment knob is placed on top of the fork.
Also, on the fork is fixed beam adapter and between the beam and the fork is stretched adjustment spring, which does not allow the fork with the wheel to rotate freely, and returns it to the operating position.

After assembly of the active tiller you must screw the bolt of the chain stabilizer into the hole at the bottom of the gearbox, the bolt with M8 marking is suitable for this purpose. All, the device soil tiller (cultivator) is assembled. The machine can be connected to a power tiller.

These models have been on the market for a relatively short time. They can be used to till any virgin soil, and they are also effective in hard and difficult soil cultivation.
- solid construction that provides high performance accuracy;
- The equipment is good against weeds;
- ease of operation, the ability to replace parts at home.
Unlike sabre-tooth tillers, these models are made from carbon steel, which is not as strong.
Frequently Asked Questions About Single Axle Tractor Cutters
One of the most common questions is considered to be: “Do milling cutters need to be sharpened on a single-axle tractor?” The answer to this depends on which knives you have installed and whether they are self-sharpening. The answer to this question also depends on the type of soil you are going to work with. If you plan to mainly plow wet soil, it is recommended to additionally sharpen with an angle grinder. The sharpening of power tillers is important and requires special attention.
Which cutters are better: saber or goosefoot
To understand which cutters are better: the classic saber, or modern. goosefoot, consider the advantages and disadvantages of tools on the basic criteria.
- Cultivation efficiency. With the same working width, there are twice as many “tines” on the hubs of a gooseneck tiller as on its sabre-like counterpart.
- Functionality. While standard sabre cutters are designed for medium-density soils, gooseneck cutters allow for efficient tillage of heavy, clayey soils. Another advantage of the latter is their gentle cultivation, which is expressed in slight damage to the root system of the plants grown.
- Working element material. Sabel-type cutters are made of high-carbon hardened steel, which is an advantage of this model. The welded construction of goose legs is made of ordinary carbon steel 3.
- Breakdowns and repairs. The material from which the models under consideration are made determines the susceptibility to mechanical damage. On goosefoot tillers, the “legs” often break off when working on hard soils. Only a welding machine can repair this defect. On the other hand, sabre-tooth cultivators have a collapsible design, and in case of breakage the working elements can be easily replaced.
- Price. Goose-foot tillers are much cheaper than their saber-like counterparts.
How to assemble a tiller for a power tiller
The factory-assembled burrs are installed according to the assembly instructions. For convenient work use special 50 cm high X-shaped trestle, made of wood. a single-axle tractor is mounted on a coulter. An inclination angle of at least 45° is necessary. The trestle is placed under the handlebar and the wheel is removed.
When assembling the tiller, remember that the equipment consists of right and left parts, which are fastened so that when the equipment moves forward, the blades with their cutting edges enter the ground. That’s why this unit is fastened facing the direction of travel.
Before installing the cutter on a single axle tractor with your own hands, you need to check that the grooves and holes on the blades and petals of the linkage correspond to each other in diameter. If the assembly diagram is not correct, the tiller will deviate from the selected direction during operation, milling the cultivated surface will become difficult.
Cutter for single axle tractor Kentavr: meaning, application
Cutter for power tiller Kentavr breaks up large clods of earth when working, allows you to comprehensively process the soil, which is the main task of the device.
The cutter consists of blades (made of strong steel) which are bolted to the frame. The frame itself is presented in the form of a so-called “herringbone”.
It should also be noted that the active tiller for the power tiller allows first-class processing of the ground, and with minimal labor costs.
