Is it necessary to grind tillers on a power tiller?

How to assemble correctly

Quality and speed depend on the correct assembly of the cutting elements. Before assembling the cutters of the motocultivator, it is necessary to carefully inspect the elements included in the kit. On them we will see the stamped letters L and R. That means left and right. To avoid confusion, let’s divide them into two identical groups. The hubs on which the blades are mounted can be round tubular or hexagonal. It depends on which shaft the cultivator has.

On one side there is a small ledge with a hole for the cotter pin and a mounting place for the first link of blades. Let’s take one of the half axles. It will be on the left side, in the direction of travel. Assemble the first link, starting from the gearbox. Set cutting edges in the way that they make a counter-clockwise circle. Put the right and left blades alternately. With 4 elements, 2 knives lie on the bottom, 2 on top of them. Where on the half-axle there is a cotter pin hole, the blade must be higher in front of the hole. Otherwise there will be difficulties with installation and removal of cotter pins.

Screw the element so that the base plate is between it and the gearbox. Otherwise the blade can get caught on the gearbox cover. When the first link is complete, assemble the second.

We look at any of the screwed knives, on the next plate we find such a position that the new knife looks in the same direction, but it is shifted a few degrees counterclockwise.

On the attachment plates, the cutters are placed on the same side as the first link. This is necessary to maintain the same distance between them. A correctly assembled power tiller looks like a spiral when viewed from the front. Assemble the right router in the same way.

Varieties

In power tillers with a PTO shaft, a set of cutters can be a separate attachment. The unit is rotated by the belt transmission. The progressive movement of the machine is carried out by wheels or grousers. The single-axle tractor itself moves slowly, while the cutting units rotate at least 3,000 rpm. In this case, we can say that it is an active cutter, referring to the type of its feed.

On light-duty tractors and power tillers, the cutting units are mounted instead of the wheels. They rotate and cut the soil while moving the machine. Here the feed type is passive, so it’s called a passive power tiller.

Active saber motors

Calling a tiller “active” or “passive” just because of its design features is not quite right. The saber-shaped elements are a good combination of quality and performance. They are made of alloy steel. In the factory the cutters are hardened and treated with HF currents. They are low-maintenance and work well on all kinds of soils.

Generally, the cutters are assembled in links on hubs, 3 or 4 at a time. Each link is shifted relative to the neighboring one at a slight angle. Their curved ends are alternately turned in different directions. As practice has shown, 3 elements in the link do not give a stable motion of the unit. The design jumps and is difficult to control. That is why it is necessary to buy cutters with 4 blades. Working width depends on engine power. It varies from 0,8 m to 1,2 m.

Farmers try to make saber-shaped tillers with their own hands. Even if steel from springs can be found, there is a problem with giving them a curved shape. This requires machining in a forge, welding is not helpful here.

Goose legs

Another good thing for gardeners and farmers is to equip their cultivators with a goose-foot tiller. Initially, craftsmen made them themselves, but now you can buy such a version in stores. The design has its own advantages:

  • a welded device made of a suitable material;
  • Sharp cutting blades;
  • Possibility to replace any worn-out element.

Such assemblies are used when it is necessary to cultivate virgin land. Thanks to the high rotational 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, entering the layer at an acute angle, loosen and mix the fertile layer. When using goosefoot tillers, there is no need to re-cultivate the plot.

Sharpening of cultivator tines. What is a cultivator and what is it for

Cutter. the main working “organ” of the cultivator. With its help, both loosening, and weeding, and preparing the soil for planting. For mechanical models, as well as units of ultra-light and light category, it acts as the only functional element. Machines of the medium and heavy category also use trailed equipment.

Do the blades of a cultivator blade need sharpening??

Cultivators are used to facilitate physical labor when cultivating the land. These are driven by electric or gasoline motors and act on the ground with a special burr. The working elements of the latter are metal blades. The blades dig into the ground during tillage and loosen it. This causes damage to the cutting edges. Sharpening knives periodically. If done properly, it will be more effective to work with a power tiller.

How to make milling cutters for a power tiller with your own hands?

Soil tillers do not have a complicated design. Before making the device yourself, it is necessary to pay attention to store analogues to assess the design features and make an effective inventory.

Drawings are needed with exact dimensions, specified parts, sequence and connection options. Required materials are prepared. If there are shaped parts, they should be pre-ordered from the master. Teeth should be arranged on the same principle as on the store products.

All work should be performed as correctly as possible to increase the performance of the canopies. Incorrectly assembled construction will pull the power tiller to one side.

Sabre-shaped cutters are among the safest. Knives, transversely arranged, are plunged into the ground, one after the other, without jerking.

It is necessary to prepare such materials and tools:

  • Metal pipes with a diameter of up to 420 millimeters;
  • Sharp parts under the knives;
  • angle grinder;
  • Welding.

The process of creating an active cutter:

  • Blades are adjusted to size and bent at a certain angle in one direction;
  • Blades are welded to the tube from different sides;
  • It is better to pre-sharpen the blades behind the movement;
  • The finished device is mounted on the hitch.

Experts say that the optimal diameter of cutters up to 50 centimeters. In this case, the equipment will plunge to a depth of 26 centimeters with a coverage width of one meter. These parameters are sufficient for quality ploughing.

To extend the life of the homemade cutters, it is worth following the rules for operating the equipment:

  • When starting the motor, the blades should be positioned over the ground;
  • The engine is switched from idle speed, and the blades are gradually lowered to begin plowing;
  • Sharpening should be done as often as possible for better ground treatment.

Cultivator cutters: types, purpose, choice, how to assemble

The choice of good equipment is an important factor for ennobling land plots. The land is cultivated when using a cultivator equipped with high-quality cutters. To do this, you need to understand what it consists of and how not to make a mistake when buying it.

People are interested in the answer to the question of how to assemble the cutters themselves. After spending only 10 minutes of your time, the reader will get useful information about the production, choice, quality evaluation of rotary hoes for cultivators. In addition, get useful tips on how to produce good blades, recommendations on the choice of materials for manufacturing, as well as criteria for assessing the quality of equipment. Separately considered the question of how to assemble milling machines by yourself.

Cultivators with an active tiller

Cultivators with an active tiller can work on difficult terrain. This is done thanks to its equipment. At the same time, there are almost no restrictions on the use of this type of model. Especially good are sabre blades on soft types of soil.

When cultivating a plot of land with elements of stony rock or weed roots, it is advisable to use a cultivator with an active tiller. This will secure the damage of the cultivator and prevent it from breaking.

This type is often used in country plots. Externally, it looks like an ordinary curved strip of metal. When developing great speed, the ends of the metal strips are able to go deep into the ground and destroy everything in their path.

This is all you need to know when preparing to cultivate your plot. It is up to the reader to choose the type and method of its production. However, the information that has been outlined here will be very helpful in making the choice. It is especially useful to understand what is the assembly of the tiller.

You should not ignore the written advice, because it was done for educational purposes. Differences in the design of the cultivator and the rules of operation of the equipment are important. With proper care and application there would be no need to replace the tiller with a cultivator.

Deep tillage

When developing new areas it is necessary to plow the virgin land. It usually gets overgrown with turf, perennial grasses and weeds. Such areas are rather difficult to handle with conventional tools. Cultivation with deep tillage with layer turning is used more often. At reverse plowing part of the layer is cut, lifted and turned around its own axis. As a result the soil from the first layer gets on top. Weeds cannot grow for a while. Cultivated plants get a head start.

This kind of work is done in autumn. The roots of nettles, couch grass, dandelion and other weeds get frozen in November and December, when the air temperature is cooler.15-17 ⁰С (no stable snow cover yet). Later they lose the ability to grow.

In the future, this method is resorted to every autumn. After 2 4 years of autumn autumn autumn fallowing the amount of weeds on the plot is many times reduced.

Proponents of organic farming do not agree with this approach. But the experience of several centuries proves that only with such agrotechnical operations it is possible to clear territories from weeds. Otherwise you have to use chemicals to control weeds.

  • to wrap the soil layer and allow plants to use substances for nutrition, which gradually shift to the lower horizons during the season. This operation allows to reduce the salinization of soil by mineral fertilizers, and reduce the amount of fertilizers applied;
  • aeration of the lower soil layers promotes 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 the roots of the rod type is stretched for several years. Anaerobic processes (without air access) occur with slow accumulation of humus;
  • The weed seeds get caught in the lower layers of the soil during the plow rotation, and cannot germinate. The roots remaining on the surface freeze out. As a result, the weed infestation is drastically reduced;
  • 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 nourishment;
  • The application of organic matter before plowing allows you to organize the active decomposition of manure or green manure, if they were sown after the harvest of the main crops.

Which tillers are best

Saber-type nozzles are suitable for all soils. For areas with rocks and large roots, it is recommended to use attachments with high performance. In active tillers blades do not break because of high quality material. cutting elements are characterized by maximum reliability, robustness and service life. Cutter bars are mounted on cultivators.

Goose-foot milling machines are characterized by high passability of the cutter on virgin, untouched by agricultural machinery, as a result of which the soil is processed quickly and easily, the ground lump is thoroughly crushed and mixed at a depth of 30-40 cm. They are suitable for stony and hard-ground cultivation, weed control, and can be installed on both power tillers and power tillers.

A disadvantage of the tool is its lower durability. During operation the knives should be constantly inspected for damage and repaired. Goosefoot material does not have such high strength characteristics as alloyed or high-carbon steel, nevertheless it lends itself well to welding processes. If the cutting elements break or crack, the product can be repaired at home with minimal expense. This quality is the main advantage when choosing a cutter.
