Do-it-yourself rotary cutter for a cultivator. Making a cutter "crow's feet" for a walk-behind tractor with your own hands

A walk-behind tractor is a full-fledged assistant where manual labor in the field or in the garden takes too much time and requires a lot of physical effort. Today, a small-sized unit can be found in almost every yard or household, it is such a useful “thing”. And in fact, the range of tasks that can be easily performed is quite wide, all kinds of land cultivation, cultivation of beds and even harvesting. And the presence of additional hook-on attachments only enhances the capabilities of a miniature tractor. One of the most effective acquisitions can be "crow's feet" for a walk-behind tractor.

Why do you need a walk-behind tractor "crow's feet"?

One of the main functions of a walk-behind tractor in a field or garden is high-quality plowing of land on a plot for further planting or sowing. For its implementation, cutters are used - the main working element of the walk-behind tractor. This is the name of the axis on which knives of various configurations are put on. When rotating around the axis, these knives, as it were, cut the earth, thereby plowing it. Due to this, cutters are also called soil cutters. When working on a site, not only the earth, but also the plants growing in it, can be trimmed. Thus, the cutters carry out plowing of the soil, and also fight weeds.

There are several types of cutters. The most common are saber-shaped, with a talking knife shape. As a rule, this is a collapsible design. The nozzle on the “crow's feet” walk-behind tractor, on the contrary, is not disassembled into parts, but has a cast configuration. They are made from carbon steel. main feature"crow's feet" - the triangular shape of the ends of the knives, providing sufficient crumbling and mixing of the soil. Such a continuous configuration is due to the need for strength when working on hard ground, virgin soil, its cultivation. Such can be considered areas where the earth is with large clods.

Features of plowing with "crow's feet" with a walk-behind tractor

Basically, the nozzle described is used for plowing a plot for potatoes, when it is necessary to remove large clods of soil or carry out development prevention. By the way, gardeners note the fact that weeds are perfectly wound on “crow's feet”, but they are not cut down. In this regard, speaking about whether it is necessary to sharpen "crow's feet" on a walk-behind tractor, we can recommend this procedure. The fact is that manufacturers do not sharpen the edges of the knives of this nozzle. After sharpening, you will notice that medium-sized weeds are easier to cut, and work on hard ground is much easier.

How to choose cutters "crow's feet"?

When choosing this important component of the walk-behind tractor, first of all, it is important to pay attention to the size of the "crow's feet" for the walk-behind tractor. This is more about matching the diameter of the nozzle axis to the landing shaft of your machine model. They are available in 30mm and 25mm. Moreover, on cutters with a diameter of 25 mm, three rows of three knives are installed. Such products are suitable for motoblocks such as "Texas", "Neva", "Caiman", "Mole" and others. Models "crow's feet" with an axle diameter of 30 mm are selected for walk-behind tractors such as "Cascade", "Salute", "Caiman Vario", "Master Yard" and others. On such a product there are not three, but four rows of knives. Moreover, the width of the treated surface is increased.

Another criterion that you should pay attention to when choosing crow's feet cutters for a walk-behind tractor is the outer diameter, which, accordingly, depends on the plowing depth. The larger this diameter, the deeper the knives are able to cut into the soil. Meanwhile, the quality of the "crow's feet" must be at the level, otherwise metal breakage cannot be avoided.

A walk-behind tractor is one of the most popular means of mechanization, which is used today in both small and large farms. The unit allows the use of various replaceable modules, due to which its use is widespread in rural areas. The main purpose of such equipment is the cultivation of the earth. Due to this, the cutter is considered the most popular module. It can be purchased ready-made or made independently, for example, "crow's feet" for a walk-behind tractor. In the latter case, knowledge and skills in working with the tool will be required.

By their design, the cutters for the earth are a set of knives that are mounted on a rotating axis. They are designed to loosen the soil. A similar element consists of several parts:

1. Conventional types are mounted directly on the shaft drive coming from the wheels. Due to this, such devices are able to move independently during cultivation.
2. There are also mounted options, where the transfer of power to rotational movements is carried out by means of a shaft from the walk-behind tractor itself.

There are no particularly serious differences between mounted, as well as conventional types of cutters. However, to use options equipped with independent rotation, it is important to separately make a model that has a shaft drive, as well as an additional double-sided angular gearbox.

"Crow's feet"

It is worth analyzing in detail the main used options for milling cutters for walk-behind tractors.

Active

Each block of knives in the "reciprocating" models has 4 cutting elements, each of which is at an angle of 90˚ to the nearest one. In total, 3 or more such blocks are installed per drive.

The number and width of the knives used is determined by the weight, as well as the power of the unit itself.

Each of the cutting elements in this design are curved strips made of strong alloy steel. In order to independently create such elements, spring steel is used, which is subjected to heat treatment, and after hardening. In this case, the bends of the cutting elements alternate in direction.

The use of the active cutter design is possible in areas where stones or roots are present, without fear of breaking the knives. However, it is recommended to use this type on light soil.

"Crow's feet"

This version of the cutters, made in the shape of a triangle, is installed on each rack. As a result of this arrangement, these models received their characteristic name. Each of the cutting elements is made of durable steel. Like active cutters, the length, as well as the number of used blocks with knives, depends on the mass, as well as the power of the power plant of the walk-behind tractor. There are at least 4 cutting elements in one block around the circumference. And the more of them, the better the grinding of the soil. However, to increase their number, the requirements for engine power also increase.

Made according to classical drawings, houndstooth cutters are used to process heavy types of earth, as well as virgin soil. But when used on the ground, where a large number of roots, cause clogging of the module and the need for its subsequent cleaning.

Each of the listed options for cultivation elements for a walk-behind tractor has its own advantages, as well as disadvantages. Therefore, when choosing suitable model it is worth considering the type of cultivated soil where it will be used.

Manufacturing according to the drawings of the "crow's feet" cultivator is recommended to be done using mild steel. Knives in such units are self-sharpening, therefore, with the correct use of the device, they do not need to be sharpened.

Creating "crow's feet"

The mass use of models of this type began in the mid-80s of the XX century. Their appearance occurred as a stage in the development of small-scale mechanization, after which the cutter showed its viability, as well as high efficiency. By design, this option is divided into certain elements, which can be created separately. Before starting the assembly, it is recommended to study the finished products. This will provide an opportunity to get acquainted with all the features of a particular type of working tool. As a result, it will be possible to draw up drawings of "crow's feet" for a walk-behind tractor with your own hands.

After determining the type of construction of the future unit, it is required to prepare the materials necessary for assembly. If there are certain figured parts in the variant of interest, it is worth ordering their manufacture from a specialist. With the ability to work with forging equipment, you can create it yourself.

All other details can be easily done by hand. In the process of assembling the crow's feet, it is important to carefully approach the installation of each element. Installation deviations must not be allowed, because as a result of this, the axis of the walk-behind tractor itself may be broken and a roll will appear in one of the directions.

Drive sleeve

Creating a cutter for soil begins with a drive sleeve. Due to the fact that this element will constantly be subjected to serious loads, it is made using a lathe. Thus, the wall thickness should be approximately 7-9 mm, and its inner hole must be cut carefully to ensure a free fit on the drive shaft. In this case, there should be no backlash. A hole is created from the back, where an axial pipe will be inserted, the planting depth of which will be approximately 35 mm. This design of the element allows you to create a connection that is completely aligned along its axis.

Additionally, you need to make a hole where the fixing pin will be inserted.

Axial tube

Such a detail can be created in a collapsible or not. If it is necessary to change the number of knife blocks over time, it is recommended to give preference to options that are disassembled. In the process of creating such a design, connecting bushings should be machined. In the future, they are half-mounted on the axle, after which they are fixed by welding or special rivets. The part of the element that will protrude allows you to connect another similar element.

How such a cutter will behave in work is determined only in the course of field tests. The result may not always correspond to the desires.

After that, a flange is welded to the created axial pipe, which will be used to mount the knife racks. You can make this element lathe or weld from metal strips having a thickness of about 5 mm. A hole is drilled in it to create a future connection with the racks.

Due to the increased load, the fastening of the elements must be carried out with rivets or with bolts. How long the tube will be is determined by the location as well as the width of the knives used. It also depends on their number, how many blanks you need to make.

Cutting elements

In order to create future knives for a walk-behind cutter, it is important to use strong steel with a thickness of at least 5 mm. The most optimal is the triangular shape of the cutting elements. This allows you to create the least resistance in the process of its entry into the ground. Often, cutting elements taken from a segment mower are used in this capacity. But in this case, before welding, it will be necessary to first harden the knives. The use of models equipped with such cutting elements is recommended only on clean soil. For work on virgin soil or other heavy soils, it is required to use more durable knives.

The width of the knives should be in the range of 50-90 mm. Too large options create increased resistance and lead to their frequent breakdown.

Crow's feet assembly

Cutter post

The part of the edge that touches the soil needs to be sharpened, and then holes must be made through which it will be mounted on the installed flange. At the end, knives are welded to it, and then they are hardened.

Knife block

The last element is the connection of the resulting blocks of cutting elements directly with the drive sleeve. It is important to strictly adhere to the drawings here in order to prevent damage to materials.

Assembly of the active cutter

Due to the simple technology of creation, this type of cutter is widely used. In it, knives, as well as racks, are a single element. For its manufacture, a single piece of metal is used, made of high-strength steel. The use of such units is considered safer than crow's feet, and there is also less risk of injuring a person during their use. Due to the consistent placement of the cutting elements, they smoothly enter the ground, without impacts. The manufacturing process until the creation of a pipe with a flange is completely similar to the "caterpillar legs".

It is worth considering in more detail how knives are made. First, the strip of metal after heating is bent so that the length of the resulting curved part is no more than 80 mm. After that, the fastener is drilled, as well as the workpiece is cooled. At the end, the element is hardened and mounted on the flange.

Self-manufacturing of a cutter for use on a walk-behind tractor requires tools and the ability to work with them. In addition, it is necessary to draw up drawings of the product being created and strictly adhere to them. Any deviations in details can cause incorrect work of future crow's feet.

When a do-it-yourself crow's foot cutter is made, the drawings are prepared after determining the type of construction:

• with 3 rows (axle diameter 25 mm);
• with 4 rows (axle diameter 30 mm).

Structural elements

Before you make a cutter for a walk-behind tractor with your own hands, the design scheme is studied. The product is installed on a walk-behind tractor or a motor-cultivator with an appropriate axle diameter. The minus of the cutter is the absence of sharp edges and the winding of weeds on the blades. If necessary, additional elements are installed on the do-it-yourself structure. You can independently make a tool with solid and non-separable "crow's feet".

To make curly cutter parts for a walk-behind tractor with your own hands, you will need blacksmith equipment. Experts recommend paying special attention to the assembly of the structure. Otherwise, the axis of the walk-behind tractor will be broken. During the installation of the product, the direction of rotation of the teeth is taken into account.

The "crow's feet" design is assembled from elements with a diameter of up to 500 mm. Such size restrictions allow the tool to penetrate the soil by 260 mm. Self-made knives should enter the ground consistently, without jerks and bumps. In order for the product to be used for a long time, experts advise adhering to certain rules. When starting the unit, "crow's feet" are placed above the ground. Then the revolutions are started, slowly lowering the blades into the ground.

To do simple design, use:

• metal pipe with a diameter of less than 42 mm;
• welding machine;
• parts used for digging the soil;
• grinder.

Car springs can be used as plowing elements. The blades are adjusted according to the parameters and bent in the right direction. Using a welding machine, the elements are attached to the pipe from different sides. The blades are sharpened in the direction of their movement. The resulting design is fixed to the walk-behind tractor. If irregularities in the operation of the unit are detected, it will need to be removed and adjusted.

A saber cutter is able to perform almost all types of work due to the shape of its blades.

In order for the equipment to simultaneously plow the ground and destroy weeds, experts recommend making a soil cutter. This tool is used in the spring for sowing. Unlike crow's feet, the soil structure is presented in the form of bent sabers, which are fixed to the shaft in right order. In this case, the shaft rotation speed is 200 rpm. The tool is installed on the back of the equipment. The operation of the unit depends on the power take-off shaft.

Crow's feet cutter for a mini-tractor is presented in the form of a rotating shaft with blades. Due to the drive, the structure is immersed in the soil, lifting and shifting it. The width of each blade should not exceed 100 cm, the weight is 16 kg, the rotation speed is 2-5 km / h, the length is 38 cm, the height is 38 cm. Using such a tool, the farmer can make beds, loosen the soil.

Blades for the device are made of steel with a thickness of 12 mm. Additionally, the material undergoes thermal hardening and treatment with high-frequency current. Knots and connections are set as rigidly as possible. As a gearbox, experts recommend using the PK-1.6 pick-up stacker. A non-separable cutter has a higher strength than a collapsible tool. For processing clay soil, it is recommended to make 2 crow's feet cutters. Do the same when early processing soil.

To change the depth of the blade, an adjustable coulter is made.

This strong plate is welded vertically to the walk-behind tractor. The tool diameter directly influences the final tillage depth.

Conclusion on the topic

The saber-shaped legs ensure safe work on the walk-behind tractor. When hitting a tree root, the tool lifts it. At the same time, soil cultivation continues. If you make a straight cutter, then it will catch on a stone or other obstacle, overturning the walk-behind tractor. The operator may lose balance.

In order for the "crow's feet" to enter the soil smoothly, it is recommended to attach them to plastics. The last elements are welded to the shafts at a certain angle. This method of manufacturing and assembling the cutter has a positive effect on the transmission of the walk-behind tractor. Knives can be made from carbon steel or springs.

Other structural elements are made of steel ST-25, 20 and 10. These grades are easy to weld. If the diameter of the structure is 25 mm, then such cutters are installed on the Texas, Krot, Neva motor cultivator. Four-row analogues are mounted on Salyut, Farmer, Cascade walk-behind tractors. At self-manufacturing milling cutters, you must have experience and skills in working with a welding machine. When fixing the elements, it is recommended to observe safety precautions (use a welding mask).

Such an agricultural device as a walk-behind tractor has not lost its popularity at all over time. On the contrary, the development of technologies has ensured the emergence of new demanded mechanisms with a wider range of functionality.

As you know, with this machine you can perform whole line tasks: transport goods, cultivate the soil and simply use it as vehicle. Since this equipment is most widely used in rural areas, you should figure out exactly how to make such a part as a cutter for a walk-behind tractor with your own hands. This structural element has many useful properties but to acquire finished device rather unprofitable from a financial point of view, which explains the need for self-assembly.

The main functions of cutters for a walk-behind tractor

This type of equipment is hinged, so that at any time it can be dismantled and replaced. The cutter is an extremely important part of the walk-behind tractor, since in the process of operation it directly affects many factors:

Quality of tillage;

Ease of driving;

Motoblock transmission condition;

Vehicle engine stability.

Many owners knowingly wonder how to assemble a cutter on a walk-behind tractor with their own hands. Only with the help of this element it is possible to qualitatively loosen the earth and prepare it for sowing, simultaneously removing all weeds.

The main part of any soil cutter is the knives. For walk-behind cutters, you can find different samples, made, however, using a similar technology. The quality and depth of tillage directly depends on what material is used in the production process.

Advantages of cutters for walk-behind tractor

Among undeniable advantages that these details possess, it is worth highlighting the following:

• cutters do an excellent job with weeds, destroying them without a trace;
• the soil treated with such an element is well loosened, which contributes to the mixing of its layers and has a positive effect on fertility indicators;
• with the help of such knives, fertilizers can be easily distributed.

In addition, when making such a part as a milling cutter, you can be sure that it will cope with absolutely any type of soil, whether it be clay, moist or very hard ground. Due to this, walk-behind tractors equipped with such devices are common in regions with a wide variety of climates and natural conditions.

Types of cutters for a motor cultivator

The development was also reflected in the device of such equipment. So, there are several varieties of cutters, but the most common of them are two:

1. System with saber-shaped knives.
2. Cutters, referred to among consumers as “Houndstooth”, due to their unusual shape.

The first product is extremely common among consumers, largely due to the fact that with its help you can perform almost any task. At the same time, a saber-shaped cutter for a walk-behind tractor is assembled without any difficulties. One of the advantages of its design is the ability to remove the knives at any time, since they are made of steel, which, as you know, cannot be processed by welding.

Milling cutters for the Houndstooth walk-behind tractor are more modern products. The main purpose of such a mechanism is the processing of hard soil rocks. When operating this model, it is important to remember that it is necessary to work with it only on flat and clean ground, otherwise there is a possibility that weeds will constantly be wound around the knives. Such a product is perfect for planting crops and can be used even in the cold season.

Materials for assembling cutters

Before assembling the cutter on a walk-behind tractor, it is necessary to measure the parameters of the area that is planned to be processed, and only then, based on the data obtained, assemble the mechanism. In order for the design to be as correct as possible, the following list of materials must be available:

• not very long metal tube with a diameter of 42 mm;
• details that will act as elements of loosening the earth;
• apparatus for welding;
• Bulgarian.

Understanding how to properly assemble cutters on a walk-behind tractor, many owners are wondering about the arrangement of soil rippers. The basis of these parts may well be the springs for the car, which are bent and then welded to the main pipe at the right angle.

The process of assembling cutters for a walk-behind tractor

To begin work, as mentioned earlier, you need to take measurements of the site. After all the calculations, you can start the assembly. Using a welding machine, the knives of the future cutter should be attached to a pre-prepared pipe. You can first sharpen the edges of the elements under the desired degree.

The resulting mechanism is fixed on the hitch assembly, and the work can be considered completed. To make sure that the entire system is functioning, you can perform a test run and adjust the device.

When assembling such a design as a cutter for a walk-behind tractor with your own hands, it is worth remembering that you can achieve the longest possible service life of the product only by strictly observing all the rules for its operation. When turning on the mechanism, the knives must be kept at the top and in no case should they be allowed to touch the ground. Having started the walk-behind tractor, the cutter can be slowly lowered and get to work.

The easiest way to assemble such a device will be for someone who has some experience in the field of metalworking. A pre-drawn scheme, as well as high-quality tools and materials, will simplify the installation process.

When deciding how to properly assemble cutters on a walk-behind tractor, many owners are faced with the problem when it is not possible to make small and curly parts of the structure on their own. To do this, it is best to seek the help of a professional blacksmith who will do this work much faster and better.

In addition, do not forget that an incorrectly assembled system entails a change in the direction of rotation of the knives, which, in turn, is fraught with equipment failure.

Having studied all the above recommendations, we can conclude that it is absolutely realistic to design such a mechanism as a cutter for a walk-behind tractor on your own, it is only important to observe all the subtleties of the work, and then the device will last for decades without the need for repairs.

The tiller for a walk-behind tractor is used for the destruction of weeds, intensive crumbling of the soil, mixing of soil layers, leveling the field surface and wrapping fertilizers. Milling cutters are used especially effectively when heavy waterlogged soils are cultivated, turfed layers are developed, hummocks are cut, meadows and pastures are improved.

Soil cutter for walk-behind tractor

A tiller for a walk-behind tractor is used during the pre-sowing period in the spring, after moldboard processing. It is not recommended to use cutters on light soils to avoid dispersion.

Outwardly, rotators look like bent knives or sabers, which are fixed on the shaft in a certain order. The shaft rotation speed reaches 200 rpm. It is hung on the back of the walk-behind tractor. The work of the tiller depends on the power take-off shaft. More best result the cutter gives during an increase in the speed of movement.

The scheme and device of the cutter for a walk-behind tractor

Thanks to the saber-shaped form, cutters for walk-behind tractors are safe to use. If the walk-behind tractor runs into a root or stone, the cutters lift it up like a car wheel, while continuing to process further. If the cutters are straight, then they can catch on an obstacle and overturn the walk-behind tractor. The consequence may be loss of balance by the operator and possible fall onto the cutters.

The knives are attached to plates, which are welded to the shafts at various angles. Thanks to this, the cutters enter the soil smoothly, in turn. This has a positive effect on the transmission of the walk-behind tractor. The blades are made from carbon steel. If you have access to a forge, using a spring, you can make such knives. For the manufacture of other parts, the following steel grades are used: St-25, St-20, St-10, which are easy to weld.

Soil cutters crow's feet for walk-behind tractors

To give greater strength to the cutters, they are made of steel, all-welded and non-separable. Such cutters are called - crow's feet cutters for walk-behind tractors. They are successfully and effectively applied when working with hard soil. They are installed on almost any cultivator or walk-behind tractor.

The main thing is that the diameter of the axis is correct. Crow's feet cutters are excellent for use in hard ground to plow it "under the potatoes". They are also used for prevention against garden pests (wireworm or colorado potato beetle) or for quick plowing of the garden.

Crow's feet cutters are divided into 3 and 4 rows. If the axle diameter is 25 mm, 3-row cutters are used for Texas, Mole, Caiman, Neva motor-cultivators, and 4-row cutters are used for Farmer, Salyut, Favorit motor-blocks. If the axle diameter is 30 mm, 4-row cutters are used for motor blocks Cascade, Pubert, Master Yard, Neva.

Do-it-yourself active cutter for a walk-behind tractor

Usually active cutter for the motor-block is on sale in a set to the motor-block. But sometimes you need to get the job done using specialized cutters that are not sold anywhere. In this case, you need to make cutters for the walk-behind tractor yourself.

In this case, you can go in two ways: make a cutter yourself or order production from a master. The first option is rather laborious. But a little time and money will be spent on the manufacture of the cutter, on the cost of materials.

The second option has a number of advantages: the master has all necessary tools and materials, and as a result, the cutter will be more practical.

First, you need to think about the functionality and design of the cutter. To do this, you should familiarize yourself with analogues. To achieve maximum functionality and safety, all design details must be taken into account. If this is not taken into account, then the cutter will not do necessary work, and all the work on its manufacture will be a waste of time.
You need to prepare the necessary materials after you have prepared the drawings. If the design of the cutter contains curly or victorious elements, their production is ordered in the workshop. And other elements are bought in the store or those that are are used.

After all the parts are made, it is necessary to assemble a normally working cutter, which not everyone can do. The assembly must go strictly according to the drawings, without any deviations in the design. Otherwise, the cutter will constantly go to the side, which will greatly complicate the work.

After the cutter is assembled, it is necessary to test its operation. If the need arises, we remake the cutter so that it does the right job.
