Is it necessary to sharpen mills on a single tractor: tips from real farmers
Every spring, the owners of summer cottages and gardens begin the season with the cultivation of land plots. This process is responsible and laborious. This is the main reason for the popularity of walkways designed to facilitate labor on Earth. But here not everything is so simple. There are several options for hinged mills for motoblocks. Each is intended for a specific type of soil and the condition of the site. Of course, after a few seasons, the condition of the milling towers worsens. And then the main question arises for the owner: is it necessary to sharpen them.
There is no unequivocal answer to this question. The opinions of beginners and even experienced summer residents are contradictory. Some argue that sharpening significantly improves and accelerates the process of cultivating the soil. Others argue that there is no sense in this, since even the manufacturers of milling do not require this.
BCS Walk-Behind Tractor with Stump Grinder
Having summarized the experience of one side and the other, among the arguments in favor of sharpening milling, the following should be distinguished:
- The sharpened cutting surfaces of the equipment penetrate the soil easier, accelerating the process of work.
- The first advantage should be reduced by the load on the power unit of the walk.Behind tractor, which extends its life and reduces fuel consumption.
- For light cultivators and with insufficiently high.Quality material knives, it becomes almost impossible to work with dumb cutters. In this case, sharpening is actually the only way out.
The arguments of opponents of the sharpening of the milling plant are as follows:
- The acute cutting surface contributes to a strong grinding of weed vegetation, as a result of which the process of vegetative propagation is increasing repeatedly. From this point of view, preference is given to the process of winding weeds on a stupid mill.
- As a result of the effects of sharp knives, the meaning of the cultivation of the soil is lost, since the soil instead of loosening is simply cut and remains in large lumps.
- The process of sharpening the milling plants is quite time.Consuming, since in addition to the sharpening directly, the cutter must first be disassembled, and then correctly assembled. In this case, the severity of the cutting elements remains for a short time. After that, the procedure should be repeated again.
The need and the rules of sharpening during operation
When working a walk.Behind tractor, the working surface of the knife will inevitably wear out. To restore the cutting ability of the tool, it must be periodically tightened. The timing of the procedure is purely individual. The speed of wear of the knife depends on such moments:
- The intensity of the use of the motor block;
- Firmness of the processed soil;
- The presence of plant roots or stones in the ground;
- The strength of the material of the knives.
Manufacturers of agricultural equipment supply mills already with sharp blades. Therefore, when buying a walk.Behind tractor, it does not make sense to drag knives. However, the procedures cannot be avoided with intensive operation of the unit. To restore the sharpness of the knife, an angular grinding machine (angular grinding or “corner grinder”), a sharpening or diameter of 12.5 cm with a diameter of 12.5 cm, will be required. You can use a grinding machine, however, the dimensions of the cutter and the curvature of the blades will not give a good result. If the knives are small in size, they can be sharpened with fine.Grained sandpaper.
To tighten the working edges at an angle of 45 °. Remove the layer of metal from the side of factory pointing. At the same time, do not get too carried away: just hide 1-2 mm. During the season, you may need to restore the cutting ability of the cutter several times, and excessive removal of the metal reduces the strength of the knife. In some cases, the frequency of sharpening increases. It all depends on the intensity of operation and the type of crushed soil.
When using a cutter in wet soil, it is necessary to carefully clean the surface of the blades. During friction on the ground, the surface of the metal is cleaned of an oxide film and becomes chemically active. This process is accompanied by enhanced corrosion, which entails the formation of ospins, chips, microcracks. To prevent such phenomena, the blades should be treated with special inhibitors or car oil.
Pointed knives will ensure high productivity and quality of the cutter. Before you sharpen the blade for the cutting cutter, you need to study its configuration: shape, length, type of fastening, material.
How to work properly by a walk.Behind cutter on cutters. How to configure a cultivator correctly?
In order to exclude the burden of the cultivator and a number of other common problems, the owner of the equipment must perform a number of actions to prepare and configure it.
- First, the cultivator must be installed on a thick board and remove the factory wheels from it. Instead, you need to fix one set of mills on the left and right side. 8 cutting knives include one set of cutting. This number of elements gives the best result when treating soil;
- When installing milling, you need to pay attention to the position of the knives. They should be directed only forward. The working part of each of the knives should not be acute. Otherwise, the cultivator will not move forward, but will begin to explode into the ground. In addition, sharp mills will cut off the stalks of weeds, and not wrap and pull them out with the roots;
- Further, the equipment will need to be installed in the earring necessary for the installation of a coupon;
- Sushnik is a bar with holes made in it. It is necessary to accurately adjust the position of the milling cutter during the cultivation of the site;
- To fix the council, it must be installed in earring and fixed with cords and bushings. For this, the second hole is selected. The countdown is carried out from the lower part of the council. Thus, the depth of cultivation will be 20 cm. This is enough for high.Quality soil processing and eliminating large weeds;
- To increase the depth of cultivation, the couch must be lowered down, and attached to the earlier through the upper hole of the element;
- To reduce the depth of plowing, the couch should be lifted up, and fixed on the earring through its lower hole.
Which is better
Milling cutters for a motor.Cultivator are selected for each type of work and depending on the structure of the soil. Sable.Shaped mills, loosening the soil to a depth of 35 cm, are lifted to the surface of weeds. At the same time, they do not cut them into small parts, but wrap them up and shafts. What they do not allow them to multiply. In addition, the soil is a larger “grinding”. But on dense or virgin soils, knives-plots are poorly included in the ground. Large and curly weeds are quickly wrapped in the working part and inhibit processing.
Crossbars “Goose paws” do a great job with difficult soils and all types of weeds. However, due to the fact that they cut them in an acute edge into pieces, weeds propagate. There is a option of combined use. In the fall, you should go through the site with these cutters, and in the spring and during the season to work with saber.Shaped incisors.
How to assemble mills for a walk.Behind tractor
Motobogloks and motor cultivators of the Aurora company, and, in principle, as in many other manufacturers, are delivered with cutters in disassembled form. Often, for owners of new technology, the process of assembling milling plants becomes some problem. In this article, we describe from the details of this “designer” to collect working mills. For the technique of Aurora, depending on the model, cutters are available on the axes, two sizes. The diameter of the axis for light equipment is 23 mm, and for a heavy 32 mm.
Mills for light motoblocks and cultivators gather quite easily. To do this, install the blades in special installation nests and fasten them with bolts
It is necessary to pay attention to the direction of the cutting edge of the blade. She should look in the direction of motobog
In addition, each blade has a marking. If the letter “r” is indicated, it means deployed to the right side, respectively “l” in the left.
Each next section is fixed from the previous one by means of a pin and blocked by a hairpin. The cutting disk must be fixed with a bolt. Depending on the power of the equipment, the amount of milling plants 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 fasteners on the axis. If the axis of the milling cutter is straight, without displacement relative to each other, then the number of blades will be three. For models with displaced. Four.
Four.Petrost cutters gather sequentially, one left, one right. It will be easier to assemble mills if at the very beginning to divide the left and right blades into two parts, for the left and right mills.
Three.Lobed gather differently. The first blade is installed on the axis and fixed with a bolt. In the future, this bolt will have to be removed to fix another blade. If the first was installed outside the plate, then the remaining two should be mounted from the inside of the fastener plate. For three.Lobed milling, labeling “l” and “R” are installed separately for each side.
The same.Based tractor is a truly universal machine, which is an excellent assistant for a farmer, the size of the economy of which has not yet reached the size so that there is a need to purchase a tractor. In addition, the same.Based tractor is much more compact. Depending on the installed attachment equipment, it can replace many individual units, saving a lot of funds to the owner. Frasure is one of the most important types of “hitch”. Therefore, many owners puzzle over how to assemble mills on a single tractor and how difficult it is to do it yourself.
How to assemble and install cutters on a single tractor
To start working with a mini-tractor, first collect cutters from a standard set. It includes: 8 pairs of knives (the steam consists of 1 left and 1 right knife), fasteners (nuts, washers, bolts). The collection instructions are included with the details, which is carefully studied. The following recommendations will also help to avoid problems:
- The cutting elements are laid out in pairs, so that it is more easier to determine the right and left knives;
- The knives are installed on the rotor axis perpendicular to each other;
- On one block, 4 knives are combined and attached to gearboxes;
- Check the correct assembly;
- Tighten the fasteners.
When assembling, make sure that the active sharpened part crashes into the soil during operation. Errors in the balancing of the axis will lead to the fact that the machine will enter the machine during the cultivation of the Earth. If you do not deviate from the instructions, the assembly will take no more than 60 minutes, and the part will turn out to be strong.
If an experienced summer resident copes with the previous stage alone, then the assembled part on the motor.Cultivator is usually installed together. This avoids injuries, and also not to damage agricultural technology. First, the mini.Tractor is raised. The steering wheel is propped with finished goats made of wood or knocked down crosses with boards. The optimal support height is 50 cm. If the machine is stable, the wheels are removed from it, instead of which the mills collected earlier are installed. Special plates are installed on both sides, which allow the walk.Behind tractor to move smoothly and make it more stable.
How to sharpen a home.Made cutter correctly?
Manufacturers of motor cultivators supply equipment with already sharpened standard cutters on sale. However, what to do to a person who made mills for the existing cultivator on his own? In this case, it will be necessary to perform the independent sharpening of the cutting knives of the device.
To sharpen the equipment, you will need an angular grinder equipped with a diamond circle with a diameter of 12.5 cm. Otherwise, you can use the grinding machine, but it will be difficult to use it in connection with the dimensions and the direction of bending knives. If the manufactured mills are equipped with small knives in size, then for their rapid sharpening you can use fine.Grained sandpaper.
To sharpen the knives of a home.Made cutter for a cultivator, it is necessary strictly at an angle of 45 °. In this case, it is necessary to independently determine the side that deepens into the soil. It is not required to remove too much metal from the knife, 1-2 sharpening in one season is quite enough. In some cases, the frequency of sharpening knives can change. It all depends on the intensity of use and the type of soil processed. With intensive work, the cultivator in wet weather will need to monitor the state of the milling. To exclude the formation of corrosion, they should be treated with a special anti.Corrosion compound, which can be found in almost any automobile spare parts store. It is also very important to try to exclude cutters on stones and other solid items. This will help extend the life of operation and reduce the need to sharpen the cutting knives of the device.
Features of the knife cutters of the cultivator
Clamp for a walk.Behind tractor (soil). A device for soil processing. They are installed on light cultivators instead of wheels. For heavy models of motor blocks or ministers, they are made by type of attachment equipment. Use soils for grinding, loosening or alignment of the earth. The attachment equipment in the development of virgin lands has established itself well. As well as it is used to make fertilizers and odorless siderates.
Types of knives for milling cutters
First of all, the design features of the knives determine the depth and type of processed soil. For dense and hard land, as well as more intelligence, thicker. If they plan to process a arable layer of large depths, use long blades. To improve the capture, the cutting tool has a curved shape. The direction of bending is on the right or left side.
7 useful devices for modern summer residents are the opinion that work in the country is a rather tedious lesson that takes a lot of effort and time
The cutting organ by the method of attaching to the milling body can be collapsible or monolithic. The latter is a whole design without the possibility of replacing damaged parts. Practical is the collapsible option. In this design, it is possible to change the failed component. In addition, having a set of replaceable knives of various lengths, you can quickly perform tincture of the device for processing the soil to different depths.
Material for the manufacture of knives
In order to withstand heavy loads during operation, and also to be resistant to abrasion, cutting canvases are made of high.Quality carbon steel. Such material tolerates heat treatment well to increase strength and hardness. Hardening by an order of magnitude increases the wear resistance of the tool. Some manufacturers make the cutting part by forging. Such a detail has great durability.
The effect on the pressure steel during forging causes the effect of sticking in it. Hardening of the surface layer of metal. This makes the cutting edge more solid, and soil such a tool should be sharpened less often than a stamped.
A plane cutter on a single tractor with their own hands is made of a metal pipe with a diameter of 42 mm on the basis of drawings of individual elements. In the manufacture of blades, they are adjusted in size and bended at a given angle. Welding apparatus welded blades to the pipe. Planting milling is performed in a fully assembled state. When assembling the module, it is necessary to dock them with the coupling of the walk.Behind tractor, when it is tested, adjusting.
In order to optimize the load and increase the duration of the cultivator service life, the width of the loosening is selected by a change in the number of hinged soil cutters.
Adjust the depth of the blade allows the customizable council. He performs all the work, no effort on the uniform tractor does not need to be applied. The steering wheel handle is slightly pressed to the ground, the coupon enters the soil more and slows down the course of technology, thereby increasing the depth of cultivation.
So that the gearbox does not rest against the unprocessed ground, the equipment is a little swing.
When working with the cultivator, the user must hold his back exactly, hands. At the level of the belt. This position of the body contributes to longer operation of the unit and will not harm health.
If the blades are dug after a long use, they must be sharpened with a corner grinder. For simplicity of maintenance, self.Substituting knives are chosen. The type of soil has a great influence on the cutting edges. In wet or heavy land, knives wear out faster.
For more comfortable work and high.Quality cultivation of soil, the frequency of rotation of the cutter for the console motor block should reach 275 rpm, the cultivator. 140 rpm.
If the mechanized equipment does not work well with the soil cutter, it is necessary to find out the cause of the malfunction and timely eliminate it. If it is impossible to carry out repairs, turn to specialists for help.
