How to properly assemble the cutters on the cultivator

Care rules

Forged steel is usually used in the manufacture, since it is stronger and more resistant to corrosion, but this does not exclude the need for maintenance.

After the end of the work, the rotary tiller must be cleaned of soil, roots, wire, and the like. You can use a cloth or brush, but do not use solvents as a cleaning agent.

Before long-term storage, the knives are covered with a layer of grease, and the ends of the shaft. with graphite grease.

Types of cutters

The device consists of four bent knives. “petals”, fixed on the shaft. Most of them are directional: when assembling, the direction of movement must be taken into account. The knives are usually bent in both directions, except for those located at the edges of the shaft. There are models in which all the “petals” are bent only towards the gearbox: this prevents damage to plants when loosening. However, in this case, the working width is reduced.

Elements are made from stamped steel. for the lightest apparatus, and from steel strip, often forged. The last option is the most durable. As a rule, the cutter is a separate part, but there are models in which two rotary tillers are fixed on one shaft.

  • Sharpened. the “petal” enters the ground more easily and does not adhere to the soil. Accordingly, the load on the engine is reduced and the fuel consumption is reduced. On the other hand, sharp blades cut the roots of the weeds, some of them remain in the ground and germinate again. Sharpened cutters should be used with great care.
  • With a semicircular edge. safer, but when loosening, they experience more resistance, more often they get stuck. Such an element removes weeds more efficiently, since it does not cut, but winds the root and pulls it out of the soil.

The cultivator cutter diameter determines the maximum plowing depth. The relative is set by the opener.

  • rivets. the element cannot be disassembled. This difficulty is not so much during storage as during transportation;
  • bolted. dismountable part. The photo shows a sample.

Welding is not used for the connection. this reduces the strength of the product.

How to choose and install cultivator cutters

The milling cutter is the main working “organ” of the cultivator. With its help, loosening, and weeding, and preparation of the soil for planting are carried out. For mechanical models, as well as devices of the ultra-light and light category, it acts as the only functional element. Trailed equipment is also used in medium and heavy units.

Features of operation

If the diameter determines the depth, then the quantity adjusts the working width. The most common option is two or three pairs of elements. There are cultivators with one or four pairs. By changing the number of rotary tillers, you can adjust the width of the cultivated strip.

The number of elements also depends on the type of soil. For do-it-yourself processing of loose light soil, the maximum number is set. For loam, virgin land, their number decreases.

Assembling the cultivator cutters

The most important thing when connecting with your own hands is adherence to the direction: the sharpened part of the “petal” should be located in the direction of the cultivator.

  • The number of sections is determined by the type of mounting plates: if they are located the same, then a maximum of three elements are installed. If they are offset relative to each other, then four or six.
  • Knives are marked. for the right and for the left side.
  • The assembly of the cultivator cutter depends on the model. three- or four-leaf.
  • The installation of the three-blade begins with fixing one knife to the plate. the bolt is not fully tightened in the first stage. The other two are fixed on the back of the plate.
  • Installation of a four-leaf or six-leaf blade is reduced to alternating fastening of the right and left knife. It is preliminarily recommended to separate the right and left “petals” for each part. An additional section, if needed, is mounted with a pin.
  • Fastening is carried out on bolts as rigidly as possible.
  • The last on the cultivator shaft is the protective disc: it protects the plants from damage.

In the video, instructions for assembling with your own hands are presented step by step.

How to assemble a milling cutter for a walk-behind tractor

Nowadays, the process of cultivating the land takes much less time than it did half a century ago. Modern manufacturers of agricultural machinery offer a wide variety of all kinds of equipment designed to make the work of farmers and land owners automated. For example, a single-axle tractor is a kind of compact and multifunctional special equipment designed to solve various tasks related to the processing of small plots of land. The single-axle tractor itself is a basic unit, which is equipped with additional equipment. Further in this article we will figure out how to assemble a milling cutter for a walk-behind tractor and achieve the maximum level of its performance.

Elements of milling cutters for walk-behind tractors

The elements of the cutters are necessary for cultivating the soil. The quality of processing directly depends on the model of equipment and the complexity of the procedure.

The milling cutter comes complete with a walk-behind tractor. But in cases where it is necessary to increase the width and depth of processing, the unit should be equipped with appropriate elements. In addition, the use of additional equipment makes it possible to simplify the movement of the walk-behind tractor, as well as to increase its service life.

For the processing of clay soil, experts recommend using two pairs of tiller-cultivators. You can change the depth by adjusting the opener, which is a solid structure located in the hitch of the walk-behind tractor in a vertical position. In this case, the final loosening depth will directly depend on the diameter of the cultivator cutter.

In order to better understand the principle of operation of special equipment, first it is worth understanding the main types of cutters, among which two types of construction can be distinguished:

  • unit with saber-shaped legs;
  • Crow’s feet.

Saber cutters for a walk-behind tractor are by far the most demanded. this is a universal type of construction, characterized by high efficiency. This model has an optimal shape. The legs are usually made of high quality, durable steel. In addition, the material is additionally subjected to thermal hardening, and also undergoes processing using high-frequency current.

The design, called “crow’s feet”, is commonly used for working hard soil. This type of mechanism is non-separable. Products of this type show their effectiveness in weed control and in the cultivation of virgin lands. Their main disadvantage is the material from which the equipment is made. Carbon steel has the most direct effect on the strength of the product, so the soil should be processed with the crow’s feet cutter as carefully as possible. Otherwise, the mechanism may deform.

How to assemble a saber cutter on a uniaxial tractor

It is not at all difficult to install the cutter on a uniaxial tractor, but first you need to assemble it correctly, setting the desired direction of rotation: the sharpened part of the mechanism should cut into the soil.

a single-axle tractor should be leaned against the coulter and then tilted approximately 45 degrees. Then the tragus must be substituted under the handlebar and simply remove the wheel.

Assembling a milling cutter for a walk-behind tractor is a process that is quickly mastered, but before proceeding with it, you should decide on the functions that the finished unit should perform. If you decide to assemble the cutter yourself, you should first make a rough drawing. After assembly, it is necessary to test the unit and make appropriate adjustments to its design, if necessary. The assembly diagram of cutters for a uniaxial tractor will allow you to understand in more detail the design of the unit.

Benefits of working with cutters

The Grasshopper rotary tiller is a form of agricultural machinery used to cultivate and loosen the soil.

The website of the manufacturer Grasshopper presents a wide range of modern high-quality special equipment designed to make working with the land easier, faster and more productive. We are engaged in the production and sale of only high-quality gardening, construction and agricultural equipment.

How to assemble cutters for a walk-behind tractor and a motor-cultivator

Motoblocks and cultivators from Aurora, and in principle, like many other manufacturers, are supplied with cutters disassembled. Often, for owners of new equipment, the process of assembling mills becomes a problem. In this article, we will describe how to assemble working cutters from the details of this “constructor”. For the Aurora technique, depending on the model, the cutters are produced on axes in two sizes. Axle diameter for light equipment is 23 mm, and for heavy equipment 32 mm.

Cutters for light motoblocks and cultivators are easy to assemble. To do this, it is necessary to install the blades in special mounting slots and fasten them with bolts. Pay attention to the direction of the blade cutting edge. It should look in the direction of movement of the walk-behind tractor. In addition, each blade is marked. If the letter quotRquot is indicated, it means it is turned to the right side, respectively, quotLquot is to the left.

Each next section is fixed with the previous one by means of a pin, and is locked with a pin. The cutting disc must be secured with a bolt. Depending on the power of the technique, the number of cutters will be different. Their number can be 24, 32 or 40.

The number of blades can also differ and can be three or four per section. This is due to the number of mounting plates on the axle. If the cutter axis is straight, without offset relative to each other, then the number of blades will be three. For offset models. four.

Four-blade cutters are assembled sequentially, one left, one right. It will be easier to assemble the cutters if at the very beginning you divide the left and right blades into two parts, for the left and right cutters.

Three-bladed are assembled differently. The first blade is installed on the axle and fixed with a bolt. In the future, this bolt will have to be removed in order to fix the other blade. If the first one was installed outside the plate, then the remaining two must be mounted from the inside of the mounting plate. For three-blade cutters, the markings “L” and “R” are set separately for each side.

Do I need to sharpen cutters on a uniaxial tractor?

This question cannot be answered unequivocally. It all depends on the individual characteristics of the walk-behind tractor, soil and conditions of use. For example, for processing heavy soils with a powerful walk-behind tractor with reinforced cutters, sharpening is not necessary. You will not see a tangible effect of this procedure, just waste your energy and time.

For processing an area with a lighter walk-behind tractor with small milling cutters, sharpening is a good option to improve the quality of work. But there are also disadvantages here. Firstly, sharpening is enough for only a few hours, then the procedure will need to be repeated, and this process is long and laborious. Secondly, sharpened knives help crush the roots of weeds, and this, in turn, can only speed up their reproduction.

If you nevertheless decide to sharpen the cutter, remove it from the walk-behind tractor, clear it from the ground. Grind each cutting element with extreme care using sandpaper so as not to damage them.

How to assemble a milling cutter on a single axle tractor

As our communication with customers has shown, some owners of Skiper cultivators and walk-behind tractors experience difficulties in assembling cutters for our machines. First, let’s talk about the differences between our devices. Cutters for Skiper walk-behind tractors are available in two versions:

  • For axles with a diameter of 23mm. Used on cultivators Skiper SK-700, Skiper SK-850;
  • For axles with a diameter of 32mm. Skiper SK-100, Skiper SK-1400, SK-1600.

You should also be aware that a different number of cutters can be installed on the axis of Skiper walk-behind tractors:

assemble, cutters, cultivator
  • 24 cutters like SK-700
  • 32 cutters like SK-850
  • 40 cutters like SK-1000, SK-1400, SK-1600

For convenience, a link to Skiper motor cultivators http://www.alfagradm.by/catalog/motokultivatori/

The number of cutting blades in each section can also be different. three or four. It depends on the location of the mounting plates on the axis. If a straight axle is supplied with your device without displacement of the mounting plates, then it means that three petals are installed on each section. If the mounting squares are displaced relative to each other, then each section should have four cutters.

The assembly of a four-jaw cutter consists of sequentially placing the left and right cutters on the mounting plate. For ease of assembly, we recommend dividing all cutters into two parts, each of which will have equal left and right petals. It is important to ensure that the cutting edges are directed in the direction of the cultivator. The additional section is attached to the main one with a pin.

assemble, cutters, cultivator

Assembling a three-jaw cutter begins by attaching the first cutter to the mounting plate. The bolt can be baited, but not tightened, as it will need to be removed later. The other two cutters are installed on the opposite side of the mounting plate, so that all three cutters are bolted to the axle. Here it is important to ensure that all the edges of the cutters are located in the direction of travel of the cultivator. Parts marked R are installed on the right side of the machine, parts marked L are installed on the left. Additional section is attached with a pin.

The first step in assembly is to fit the knives into the appropriate mounts on the hub. We place the hubs with anthers to each other, set the knives in such a way that when rotating, the knife sinks into the soil with its sharpened side.

The first is to install the knife that is closest to the boot (which is installed on the gearbox). The sharpened part of the knife should be directed along the movement of the cutter, and its curved part should be directed towards the gearbox.

By analogy with the first, other knives are installed. The second step is to prepare the gearbox: on the lower part of the gearbox we install a stop, which is bolted.

We also install the gear chain tension screw, it is installed in the center of the gearbox, between the stop and the drive gear.

Next, we install hubs with knives on the gearbox. On the hub, near the boot, there is a fixing bolt, which must match the hole on the splined shaft of the gearbox.

Further, studs are inserted into the hubs and screwed into the gearbox shaft correctly.

Studs additionally fix the hubs on the gearbox shaft.

Assembling the protective casing: On the protective casing we install and fasten the foot protection in the form of a mudguard. We fasten the fastening beam to the casing.

We install the casing on the gearbox and fasten it with bolts.

An integral part of the cutter is the wheel, with the help of which the depth of cultivation is adjusted and the seat-adapter is attached (if provided by the complete set). The wheel fork is installed on the cutter’s mounting beam, the wheel height adjustment knob is installed on the top of the fork.

Also, the adapter beam is fixed to the fork and an adjustment spring is stretched between the beam and the fork, which does not allow the fork with a wheel to rotate freely, but returns it to the working position.

After assembling the active rotary tiller, the chain damper bolt must be screwed into the hole at the bottom of the gearbox; for this, the M8 marking bolt is suitable. Everything, the device of the soil tiller (cultivator) is assembled. The unit can be connected to a walk-behind tractor.
