How many revolutions on the tiller of the power tiller

Types of cutters for a motor-block, proper assembly and installation

In this article let’s discuss all types of power tillers that are known today, their main function, and, most importantly, their assembly.к. If a power tiller is assembled incorrectly, the machine will either process the ground badly, jerking and skipping, or won’t work at all. For example, the blade can get caught in the gearbox and you can not work. The assembly of the trimmer, refers to an operation that can be as simple as it is complex. Let’s see why below.

Several types and shapes of this tillage tool are used. Let’s look at all types in detail, i.e.к. Assembly differs depending on the type of cutter.

Saber-shaped

Sabre or sabre milling cutters are the most common, classical type. These are the ones used on most power tillers. The fact that they are used on powerful agricultural machines for big fields cultivation shows their solidity and usability.

Have a number of advantages, such as interchangeable blades. If desired, one blade can be removed, sharpened, straightened, or replaced with a new one. Fastening is organized on bolts.

One blade is made as a monolithic solid piece, from a single strip of metal. there are no welded, riveted, screwed-on elements that can fall off due to high loads during tillage.

The geometry of each blade and their location relative to each other are designed in the best way to ensure that the cutting edges enter the ground easily and pass through it without unnecessary loads on the transmission and engine. At the same time, the soil is effectively loosened, lifted and mixed. There are no skips in the form of strips of untreated earth. The entire machining area is completely covered by the cutting edges of the left and right blades.

Cutters are made of special heat-treated (hardened) tough alloys. They are not fragile, to some extent can withstand, bypassing, for example, stone.

Alloy quality varies greatly from manufacturer to manufacturer.

Goosefoot

This type of construction appeared many years ago as a self-made one, made by oneself for one’s own needs. Then it was noticed, and after some modifications, this kind of cutters began to be produced in the factory for power tillers.

The pros of this option compared to the classic:

  • The sharp point of the blades penetrates the ground more easily. important when working hard, dense, hardened and parched soils. It is much easier for the tiller to work with them;
  • Grass and roots can also wind up on them, but less than on the saber cutters. The posts here are straight, not bent. Some of the fibers slip between them.

The disadvantage of this option can only be in the low-quality factory workmanship of each particular product. Welded triangular cutters can fall off. If the assembly is not designed to be dismantled, in case of a hopeless breakdown of one cutter, you’ll have to change the whole unit.

Because the tines are straight, they cut more soil than they lift, loosen, and mix. Only triangular cutters work here.

Spiral

Structurally, it’s a variation of the goosefoot.

Advantages and disadvantages are the same as for the above described goosenecks. there is a peculiarity, because of the small area of the cutters, there may be skips, not the whole area is cut and loosened.

Cutter preparation and installation.

Cutters for single axle tractors come with 16, 24 or 32 cutting inserts. Which set to choose. depends entirely on the type of soil on the plot, as well as the area to be cultivated. If you have a small area to cultivate, it is not recommended to use more than 16 sharpening inserts. A set with 8 blades on one side and 8 blades on the other is considered optimal. If you decide to use sets of 24 or 32 plates for small plots, it will significantly increase the load on the engine of your power tiller and, as a result, will strongly tire the operator.

The stage of preparing the cutters consists in the correct assembly of the sets of cutting plates. You must be absolutely sure that their cutting part is in the same direction.

Never sharpen the cutting parts of the tiller under any circumstances. If you sharpen them, the roots of weeds will not rise to the surface of the cultivated soil. The root system will simply be cut by the sharpened cutter and remain in the ground. After a while the weeds will grow again in the same place, and cultivation will be absolutely meaningless.

It is also worth mentioning that sharpened cutters quite strongly increase the load on the engine of your power tiller.

Also sharpening cutters negatively affect the specified depth of area treatment. If you sharpen the cutters, the single-axle tractor will occasionally dig into the soil when moving forward. This is because sharpened power tillers cut the ground instead of grip. This causes them to dig very deep into the ground to a depth of more than 30 centimeters.

So you have finished assembling the cutter set. Now you can move on to the next stage of preparing your power tiller. installing the cutters on it. You must carefully make sure that the direction of the cutting part of the blade is in the forward travel of the power tiller. It is very important not to mix up the left and right cutters and put them in their places.

How to choose the right single axle tractor?

Let’s summarize how to choose a single-axle tractor correctly so that it would perform its intended tasks without overpaying for it.

A single-axle tractor can have useful features that can make working with it much easier:

  • With the handlebar adjustment you can set the tiller handle in a comfortable position. the up-down adjustment allows you to adjust it to the user’s height, and the left-right adjustment sets the tiller handle to the left or right;
  • The differential lock allows you to lock the left or right wheel when turning. This function is most often available on professional heavy-duty power tillers;
  • starting the machine will help to facilitate the electric starter, which is very relevant for heavy devices with a diesel engine;
  • if there is an emergency stop of the engine, in dangerous situations (lack of oil) it will shut down.

Imported motor blocks are much more expensive than domestic ones, but they require only high-quality fuel. 3. Domestic power tillers have a lower price, and are not as “sensitive” to fuel quality as imported ones. But since their reliability is lower than that of their imported counterparts, they require more frequent replacement of components.

Can one ride a power tiller on public roads??

But the question of transporting cargo remains open. While transporting cargo using a trailer or a cart the owner has to move it on public roads.

You regularly have to deal with traffic inspectors, who don’t remind you with a warning in the form of a fine that a power tiller has no place on the road. But do not get upset, but rather stock up on the necessary knowledge and go out on the road fully armed.

Everyone knows that there is no way to get a driver’s license and pass the category exams for driving a power tiller. But by taking a tractor-trailer on the road, the driver is automatically considered a road user.

Therefore, the traffic inspector may ask to provide appropriate certification that you are not just familiar with the rules of the road, and know them perfectly.

After all, whatever you drive, on the road without this knowledge does not do. In addition, if you are traveling with passengers in the body, it is likely that all will be fined. And the reason will serve paragraph 22 of the traffic rules, which states that people can be transported only by car.

To avoid trouble, it is best to be prepared and become a full participant in the traffic on the road.

  • To open any category, even the smallest A, which allows driving motorcycles. It will be indisputable proof that you are familiar with the rules and know how to react to the various road signs and traffic signals.
  • After that, when driving a motor cultivator, take your license with you and you will be able to show it if necessary.
  • If you plan to ride a motorcycle on a regular basis, then put a headlight on it, and tape the trailer, which is a good reflection of the light of the headlights.

Following these recommendations, you will not only protect yourself on the highway, but also will be considered a legitimate participant of the road.

However, be ready that in case of violation of rules, you as well as others can be held liable.

“Celina”. spiral cutter for power tiller

If you need to cultivate a virgin land, the best choice is a spiral cutter. Like the Goosefoot, the “Celina” has an all-welded construction, which was made specially to strengthen it so that it could withstand higher loads. Spiral-welded blades, fitted with “Celina” tips.

Fast single-axle tractor. indispensable when transporting goods in the countryside or when working in a large area. Diesel single-axle tractor Kentavr MB 1081D is the fastest among the heavy-duty tractors, can reach speeds up to 25 km/h. The single axle tractor Motor Sich MB-6D has the maximum speed of 16 km/h.

Popular models of power tillers from domestic manufacturers have a much lower maximum speed. on average, 12 km/h at MB-2 and MB-23, Neva. Also a good speed has a single-axle tractor Mobil-K Gepard. 12 km / h (gearbox 41).

Making equipment. study expert advice

Cutters on a power tiller are not characterized by a complex design. Before you start to create elements yourself, you need to carefully study the store options. This will make it possible to take into account all the design features of the equipment and make an effective inventory. Before working, you need to make a drawing or use a ready-made scheme. It will need to specify the material of each of the parts, the sequence and method of attachment.

After this, it is necessary to prepare all the materials. If the design will use shaped elements, it is better to order them from a master at once.

When creating the cutter, special attention should be paid to the correct assembly. Try to avoid any deviations related to the design, because any error can significantly reduce the effectiveness of the cutters. over, improperly assembled implements will pull the cultivator to the right or left.

An important factor is the positioning of the tines. They should be set in exactly the same position as in the design of store-bought products.

POWER TILLER

Experts do not advise to make cutters with a diameter of more than 50 cm. Equipment of this size can plunge into the ground to 26 cm, covering a strip width of 1 meter. This is more than enough for good plowing.

Saber-shaped cutters are considered safer and are not capable of harming the operator if they fall on the design. Their blades are transverse and consistently plunge into the soil, without jerking.

To extend the service life of homemade cutters, it is necessary to adhere to the rules for using the equipment. While starting the engine of the cultivator, all the blades must be positioned above the surface of the soil. After switching the motor from idle speed, the blades should be slowly lowered and start plowing the ground.

Not knowing whether or not to sharpen homemade milling cutters, many beginners make a lot of mistakes. It should be remembered that the more often the sharpening is done, the better the result of ground treatment will be, and the longer the blades will not be affected by corrosion.

How to assemble properly cutters on a single axle tractor?

Assembly of the cutter with their 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 build the cutters:

  • The rotor axis is the right length. It can be split into two parts if you need to assemble a milling machine of two units.
  • Short axle.
  • Gearbox with retainers.
  • Left and right blades.
  • Bolts, washers, nuts.

Assembly does not take more than an hour, but here it is important to install the blades in such a way that they do not interfere with the rotations.

  • The long rotor axle 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 correctness of the construction is checked and all fastening elements are tightened.

This design is very reliable and can withstand quite high loads.

Plough Cutter

The plough a single-axle tractor with their own hands is made of a metal tube with a diameter of 42 mm on the basis of the drawings of the individual elements. Blades are adjusted in size and bent at a specific angle when fabricating. Blades are welded to the pipe with a welder. Cutters are sharpened in fully assembled condition. When the module is assembled, they must be docked to the hitch of the power tiller and adjusted during the test run.

In order to optimize the load and increase the service life of the cultivator, loosening width is adjusted by changing the number of hinged tillers.

The depth of the blade can be adjusted with the adjustable coulter. It does all the work, no force is needed on the single-axle tractor. The tiller arm is pressed lightly against the ground; the opener enters the soil more easily and brakes the machine, thereby extending the cultivation depth.

The machine should be rocked back slightly so that the gearbox does not sink into the uncultivated ground.

The operator must keep a straight back and hands at waist level when operating the cultivator. This body position allows the machine to work for a longer time and is not harmful to health.

If blades become blunt after prolonged use, they need to be resharpened with an angle grinder. Self-sharpening blades are chosen for ease of operation. The type of soil has a big influence on the cutting edges. Blades wear out quicker in wet or heavy soil.

For more comfortable operation and high-quality soil cultivation the rotational speed of the tiller for a cantilever tiller should reach 275 rpm, for a cultivator. 140 rpm.

If mechanized equipment works poorly with the tiller, it is necessary to find out the cause of the malfunction and eliminate it in a timely manner. If it is impossible to carry out repairs, they turn for help to specialists.
