Do-it-yourself rotary tiller for a walk-behind tractor

Types and device of the cutter for the MTZ walk-behind tractor

Motoblocks in peasant farmsteads have long ceased to be a wonder. Despite the wide variety of their brands and models, Belarusian MTZ walk-behind tractors remain one of the most popular in our homesteads. Equipped with a plow or a rotary tiller, they are able to cultivate small plots of land just as well for their large namesakes. tractors.

What is a cutter

The milling cutter is one of the varieties of the cultivator, but unlike the traditional tool, it is much more functional. Having installed the cutter on the MTZ walk-behind tractor, you can easily:

  • Crush the soil;
  • Develop virgin land plots;
  • Level the surface of the beds;
  • Mix the soil layers;
  • Close up fertilizers;
  • Fight weeds.

This tool is especially effective on clayey and waterlogged land plots, with the processing of which a traditional cultivator, even mounted on a powerful MTZ unit, is not able to cope.

Varieties of cutters

There are several types of tools that differ from each other in the shape of the working knives, but still the cutter for the MTZ walk-behind tractor is most often supplied with saber-shaped knives. Through numerous trials and experiments, the peasants came to the conclusion that it is precisely this shape of the blades on this tool that allows the cutter to perform almost all of the above operations.

Another version of the cutter for the MTZ walk-behind tractor, which is gaining popularity among its owners, is a tool in which the shape of the working blades resembles crow’s feet. It is often used to control Colorado beetles and other pests of potatoes during pre-winter processing of the site. Also, this cutter is very effective for plowing hard types of soil. However, its knives are distinguished by the property of winding the roots of plants around themselves, therefore, it is possible to work with such an aggregate only in areas that are free of weeds.

Unlike the tool with saber knives, which is collapsible, “crow’s feet” are initially made as a one-piece, non-collapsible tool, so it is much superior to the first option in strength.

Homemade cutter

In most cases, the tiller is initially included in the MTZ walk-behind tractor. But many owners of motoblocks prefer to use a DIY tool on their two-wheeled assistants.

The main advantage of such self-made tools is that the width of their capture is initially adjusted to the characteristics of the area that she has to process. However, when assembling such a homemade product, you need to be extremely careful, since the slightest mistake during its assembly leads during operation to a change in the axis of gravity of the walk-behind tractor. it will be pulled to the left or to the right all the time.

To make a homemade cutter you will need:

  • Metal pipe with a diameter of 40-42 mm;
  • Working knives for loosening the soil;
  • “Bulgarian”
  • Welding machine.

For the manufacture of working knives, old springs from a car are most often used, although any steel plates of suitable thickness will do. In accordance with the drawing, such parts must be cut to size, bent and sharpened in one direction. Then weld them by welding from different sides to the steel pipe and the cutter is actually ready. It remains only to attach it to the walk-behind tractor with the help of a hitch and. easy and productive work for it.

HOW TO MAKE YOUR OWN HANDS MILL FOR A MOTOR BLOCK

Some summer residents prefer factory equipment, others see solid flaws in it and develop their own models, and still others successfully combine the useful qualities of purchased tools with their own ingenuity and invention. The author of the letter is particularly good at this.

I planted my first garden a long time ago, in 1958, and I had to deal with vegetable gardens from an early age. I grew up in the countryside. I love to plant fruit trees, mainly apples and pears, in early spring at above-zero temperatures. the result does not come soon, you experience real joy with the appearance of the first harvest.

I pick up the wild birds for vaccination in the fall along the roads and sidewalks: they are trampled, and they grow again, their vitality surprises. I take the cuttings from the neighbors from the apple and pear trees I liked. The whole process takes only one day a year.

I cultivate the soil of the garden and vegetable garden by hand, using a shovel. For processing large areas, I used to invite a tractor with a plow. I plowed in the fall, harrowed in the spring, and six years ago I was presented with a motor-cultivator.

In order to loosen the soil deeper, I decided to make my own cutter with a working width of 100 mm narrower. On the occasion, I bought 16 segment knives from a mowing machine, but in the end they turned out to be too heavy for a motor-cultivator.

I had to cut them on the sides from the outside and two knives left and right from the inside. As a result, the walk-behind tractor began to pull well and go deep into the soil without jumps and jumps. The height of the knives is limited by the engine pallet and is equal to 160 mm, the depth of the soil rise has reached 20 cm, while the soil cultivated on the site can be characterized as heavy black earth-loam.

The cutter design is shown in the figure. The knife consists of two parts, welded together: the vertical part of steel sheet 5 mm thick and 50 mm wide, the horizontal part of the header segment 2.5 mm thick and 76 mm wide. The horizontal knife is located above the vertical at an angle of 30 ° to the main plane, like a plow with a cultivated blade. The cutting edges of the knives do not go beyond the coordinate axes (like with cutters for metal processing), which ensures the optimal angle of soil loosening (cutting angle). this is the main difference between my cutter and purchased equipment.

Later, another walk-behind tractor was purchased. When processing the soil, his milling cutter throws up a heavy unit and does not want to loosen deeply, the knives and the milling cutter itself are made without taking into account the laws of cutting. Colleagues recommended loading the machine with counterweights to increase the weight and depth of loosening, but this is an absurd decision, and I went the other way, namely: taking into account my previous experience, I made a new milling cutter. The results are very positive.

A.S. Pushkin, on this score, there are the words: “And experience, the son of difficult mistakes, And a genius, friend paradoxes, And chance, God is an inventor.” Based on the experience gained, it is possible to recommend that manufacturers produce motorized shovels (like electric mowers), relatively light and compact, carried in the trunk.

For fans of walk-behind tractors and motor-cultivators, I can recommend reworking factory-made cutters, taking into account the fact that the back of the knives is on the coordinate axis. The knife must be straightened, the top cut off at a 30 ° angle and the segment welded from the header. If desired, at the factory or in the forge, you can make a knife for the cutter in one-piece, L-shaped.

And by attaching knives of this type to tractor milling cutters, we will get a pushing plow-ripper with new possibilities in terms of labor productivity and quality of moldboard-free tillage.

Comparing the work of a cultivator and a walk-behind tractor, we can say that the former is lighter, more convenient and more maneuverable to operate. The purpose of the walk-behind tractor is wider, but its management requires more effort. He often breaks the clutch cable at the handle, when working with the mower, the fastening bolts loosen and require frequent constriction, the mower knives quickly fail, etc. I believe that all this technique was not made for summer residents, but for innovators and inventors: create, invent, try.

I will be glad if my proposals for the modernization of cutters are used by the owners of summer cottages and vegetable gardens, and manufacturers will not disregard them.

“Celina

Another popular type of milling cutter for a walk-behind tractor is “virgin soil”, which is in great demand due to its spiral shape. A distinctive feature of this species is its one-piece design, which allows it to cope without problems even with colossal loads.

The main disadvantage is the slow operation, as well as the fact that during the soil cultivation the soil is pushed out, as a result of which sometimes small holes appear.

As for the advantages, there are a huge number of them, among which the following can be distinguished:

  • unlike other types of milling cutters for a walk-behind tractor, it copes well with virgin soil;
  • characterized by an impressive depth of cultivation;
  • allows you to process the soil with high quality;
  • features a monolithic construction, which is a sign of reliability, strength and durability.

Saber cutter for walk-behind tractor

The most popular and versatile models that are effective in a variety of earthworks. These models use the optimal shape of the knives, 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.

How to assemble correctly cutters on a walk-behind tractor?

Do-it-yourself cutter assembly should be carried out as correctly as possible. And here it is especially important to make sure that the active part crashes into the ground during operation. To do this, it is initially recommended to study the drawings, and then start manufacturing the equipment.

The following tools are required to create cutters:

No Rototiller In The World Can Do Better Than This

  • The rotor axis of the required length. It can be divided into two parts if you need to assemble a cutter from two blocks.
  • Short axis.
  • Reducer with clamps.
  • Left and right knives.
  • Bolts, washers, nuts.

Assembling the structure does not take more than an hour, but here it is important to install the knives in such a way that they do not interfere with the rotation.

  • Long rotor axis equipped with 30 degree knives.
  • It is necessary to combine four knives on one block, fixing them to the gearboxes.
  • Next, the correctness of the design is checked and all fasteners are tightened.

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

Milling cutters for a walk-behind tractor: types, features, self-assembly

Equipment such as a milling cutter is necessary for any walk-behind tractor, since it can be used to carry out most of the work related to soil cultivation. Basically, the rotary tiller comes with the unit, but in cases where you need to change the width and depth of processing, you should purchase the equipment separately.

Additional cutters allow you to increase the functionality of the walk-behind tractor and simplify work with it. Experts recommend having several pairs of cutters in your arsenal.

The principle of operation of the cultivator and its main advantages

A cultivator for a walk-behind tractor. an agricultural unit for loosening, moisture conservation, hilling the soil without turning the upper layer.

Device

The walk-behind tractor differs from the cultivator in its high weight and the presence of a power take-off shaft. The cultivator is equipped only with cutters, and any mounted and trailed equipment that meets the characteristics of the equipment is aggregated to the walk-behind tractor.

The cultivators are equipped with different engines. 2-, 4-stroke gasoline, diesel and electric, powered by the mains or built-in batteries. They are compact, but inferior in power to the motors built into walk-behind tractors.

Do I need to sharpen cutters on a walk-behind tractor?

All soil mills are self-sharpening tools. Sharpening is not needed for them, as it can only spoil the structure. Only in some cases, if you have been using the cutter for a very long time and you see that it has begun to work the land poorly, you can sharpen the knives.

The rotary tiller is an important element of every machine. Homemade properly assembled cutters can be used on any modern walk-behind tractors, in particular on the Neva MB 1 and MB 2, MTZ and others. Such designs will aid in the cultivation of the land and make it easier to carry out agricultural tasks.

The importance of making the right choice

Many novice summer residents think that the most important thing is to purchase a high-quality walk-behind tractor, but they do not pay due attention to the choice of cutters. Such a mistake can be costly when processing the territory, since the correct choice of cutters affects the following points.

  • Cultivation quality. If you purchase and use high-quality cutters, you can even do without a plow.
  • Saving time. Good cutters allow you to spend a minimum amount of time on certain work on the processing of a summer cottage.
  • The cutters provide easy control of the walk-behind tractor. An incorrectly selected part can cause increased stress on the operator during the milling process.

In addition, bad milling cutters can put an increased load on the gearbox of the walk-behind tractor, which will negatively affect its durability and performance. It is necessary to choose such elements based on many factors, including the power and type of soil to be treated.

Carefully study the features of your walk-behind tractor, since the following are important: the cotter pin-stopper of the wheel, trailed, PTO or rotary machine, as well as other points.

Cutters for walk-behind tractor

Milling cutters are one of the most commonly used types of equipment for motoblocks. It is quite difficult to overestimate the role of milling cutters in agriculture, because these devices allow you to process the soil with high quality and fully prepare it for further planting with a minimum amount of time from the efforts of the farmer.

Homemade milling cutters for a walk-behind tractor. the procedure for manufacturing equipment

The simple design of milling cutters for walk-behind tractors allows you to make such devices with your own hands. Below we will consider the correct procedure for the manufacture of different types of equipment for plowing the soil.

How to assemble correctly cutters on a walk-behind tractor. manufacturing saber equipment

Immediately before the manufacture of saber-shaped rotor devices, we advise you to study the drawings that will tell you the correct procedure for assembling the equipment.

Any saber cutter for a walk-behind tractor consists of two interconnected blocks, each of which contains 12 cutters. The design of one separate unit includes 3 units, each of which is equipped with 4 cutting knives. The latter, in turn, are located in relation to 30 ° in relation to each other. The assembly of saber-shaped devices is as follows:

  • First, make a stand using a 6.3 × 4 cm corner;
  • Weld one of the ends of the rack to the flange so that later you can combine 4 cutting knives with each other;
  • Connect all cutting elements of the cutter to each other by means of flanges and bolts with washers.

A rotary milling cutter manufactured in this way has high strength and stability, which will allow you to use it for processing soils of any density.

Self-installation of cutters on a walk-behind tractor

Self-installation of equipment on a walk-behind tractor is performed in exactly the same way, both for saber cutters and for devices such as “crow’s feet”.

In any case, the procedure is as follows:

  • Place the manufactured cutters on a special wooden “goat”, about 0.5 m high;
  • Gently tilt the walk-behind tractor at an angle of 45 °, and rest it on the opener;
  • Place the “tragus” under the handlebar grip of the walk-behind tractor;
  • Dismantle the standard wheels of the agricultural machine, and install homemade cutters instead;
  • At the left and right outer ends of the cutters, securely fasten the discs for the cutters. they will significantly improve the movement of the walk-behind tractor with cutters and make it smoother and more stable.

After completing all the above steps, you can start processing the soil. During work, do not forget to monitor the reliability of the fastening of the plates, fixing the main and additional cutters on the walk-behind tractor.

Which cutters are better for a walk-behind tractor. we decide on the choice

Many novice farmers find it quite difficult to decide on the right cutters for the job. In fact, there is nothing difficult about this. you just need to study and compare the qualities and characteristics of different types of equipment. The cutters available on the market are divided into 2 types:

  • saber cutters. devices of this type are in the highest demand, it is these cutters that are included in the delivery set of many walk-behind tractors. Among the main reasons for the popularity of mills of this type should be highlighted the highest efficiency, the ability to cultivate any soil, including that previously untouched by agricultural machinery. High-quality models of saber cutters are made in 2 stages: first, products of increased strength are formed from carbon steel. At the next stage of production, knives are subject to prolonged heat treatment under the influence of high-frequency currents. The main feature of high-quality saber-shaped devices is the impossibility of welding cutting surfaces;
  • cutters “crow’s feet”. equipment of this type appeared on the market relatively recently. In practice, hard soil lends itself to processing with such devices. free of hard weeds. The high efficiency of these cutters is achieved due to their specific shape. The latter also allows you not to harm the roots of the planted plants during the cultivation of the garden. Among the main disadvantages of this kind of devices, one should highlight their low strength and a lot of inconveniences during repair.

When buying any of these types of cutters, be sure to consider the type of soil to be processed before and after planting.

Production of crow’s feet cutters

Immediately before assembling this type of fixture, you will need to carefully prepare for work. With tools and materials you will need:

  • steel pipe, 4.2 cm in diameter;
  • steel plates for making cutting knives;
  • welding machine;
  • grinder with a set of discs.

The active crow’s feet cutter is assembled in the following order:

  • For the manufacture of cutting elements, you can use the springs from the car. Cut them into equal pieces, and then weld them to a steel pipe that plays the role of a base;
  • Sharpen the edges of the cutting elements and weld them to the base used;
  • After assembling the equipment, start it and make the necessary settings. At the same time, keep in mind that after starting the walk-behind tractor, the equipment knives should hang in the air, and not touch the ground.

In order for the crow’s feet cutter to last as long as possible, it must be slowly lowered to the ground. Otherwise, the equipment may break.

Do I need to sharpen cutters on a walk-behind tractor. we figure it out together

It is rather difficult to give an unambiguous answer to this question due to several factors. Firstly, the recommendations of the milling cutter manufacturer are of great importance. Some companies that make high quality plowing equipment do not advise sharpening cutting elements, as this will degrade the efficiency of the cutters and void the warranty for their service. Other manufacturers, on the contrary, recommend that you definitely sharpen the cutters before each season of operation of the walk-behind tractor.

The second important factor is the result that the sharpening of the cutters can bring. The only, but very important advantage that this procedure gives is ease in the cultivation process, because it will be much easier for sharpened cutting knives to go deep into the ground and plow it efficiently. The disadvantages of sharpening include the need to dismantle and install equipment on a walk-behind tractor every time. Another very important drawback is the ability of cutters to grind weed roots deeply hidden in the ground, which will lead to their intensive vegetative reproduction throughout the entire area of ​​the garden.

The third factor is the type of soil being cultivated. If a rotary tiller on a walk-behind tractor is used mainly for the processing of hard clay soils and virgin lands, then sharpening the cutting knives will help to plow such soil faster and better. If the soil in the garden is soft, then, as a rule, it is not necessary to sharpen the used set of cutters.

All of the above advice on the manufacture, installation and sharpening of devices are suitable for the operation of equipment in tandem with Neva MB-1, MB-2 walk-behind tractors, as well as agricultural machines of the MTZ, Celina brands and units of other imported and domestic manufacturers.

Installing cutters on a walk-behind tractor

To install the cutters on the walk-behind tractor, you should use special wooden tragus, the height of which should be about 50 cm. The unit must be supported on the opener and tilted at an angle of 45 degrees. Then the wheels are removed from it and cutters are put on. Special plates are installed on the outer ends on both sides, which make the unit run smoother and more stable.

Crow’s feet

These models have appeared on the market relatively recently. With their help, any virgin land can be cultivated, they are also effective in the cultivation of hard and difficult soil.

Features of this type of cutters:

  • solid construction, which provides high performance accuracy;
  • the equipment fights weeds well;
  • ease of use, the ability to replace spare parts at home.

Such models, in contrast to saber cutters, are made of carbon steel, which is slightly inferior in strength.

Which cutters are best for a walk-behind tractor?

Such “knives” for tillage can be roughly divided into two large groups. Each of them has its own characteristics and is suitable for a certain type of work.

Homemade milling cutters for walk-behind tractor

Manufacturers offer different options for tillers for the walk-behind tractor. You can use one set of cutters or purchase two different types of devices, changing them depending on the conditions of soil cultivation.

Some craftsmen prefer to use homemade products, which, when properly assembled, will be no worse than factory ones.

The main advantage of self-creation of a rotary cutter is that it can be adjusted to the specific features of the site.

How to assemble correctly cutters on a walk-behind tractor?
