Homemade cultivators. Homemade cultivator for walk-behind tractor

Technical support in the modern farmer’s economy certainly includes means for cultivating the land. For this purpose, cultivators and walk-behind tractors are used, which, depending on the model, can perform tasks of loosening, leveling, cutting weeds and other operations. Since the device of the working body is technically elementary, it will not be difficult for a skillful home master to make such a device with his own hands. As a rule, home-made cultivators are not inferior in effectiveness to factory analogues, but it is important to calculate how to install them on a walk-behind tractor or tractor. However, manual models are also common today, the operation of which does not require connection to other equipment.

General information about cultivators

homemade cultivators

The concept of "cultivators" for many is associated with mini tractors and walk-behind tractors that perform soil cultivation functions. However, if you delve deeper into the terminology, it turns out that the cultivator is only part of the technical tool that is directly involved in the processing. Depending on the design, homemade cultivators can carry out several work operations. They can be universal both in processing and in combination with additional equipment. Before proceeding with the manufacture of such a tool, the nature of the work and the need for its connection to a tractor or other equipment should be assessed.

The simplest option for making a cultivator at home. This is a small design, the capabilities of which are enough to capture a strip 20 cm wide. The base of the device will be a handle in the form of a metal pipe with a diameter of 2.4 cm. The length of the element is selected specifically for the growth of the user. On the bottom of the pipe you need to install a solid axle made of wood. The processing organs will be attached to it. Despite the simplicity of design, homemade hand cultivators can be supplemented with wheels. They can be cut out of a metal sheet 0.3 cm thick and fixed with nuts.

There is another design option, involving a base in the form of a spring metal tape. In this case, the parameters of the workpiece should be as follows: length - 5 cm, width - 2 cm, and thickness - about 2 mm. A wooden handle is attached to this part, through which processing will be carried out. The tape is bent, so you can give it a loop shape, and then make a double-sided turning of the edges with a file. The diameter of the loop can be any, this parameter is calculated based on the area of ​​the garden.

Rotary disc cultivator

This is a more serious unit, with which you can perform loosening, and leveling the soil, and hilling. In its design, a homemade cultivator cultivator assumes the presence of the following elements: disk, axle, rod and bushings, large and small brackets, handle and pipe. Functions of working components are performed by discs welded to the bushings. The latter, in turn, are placed on the axis of the cultivator. Axial ends are fixed in brackets with a cotter pin. In a large bracket in special grooves, a pipe with a crossbar and a handle is installed. A rod 25 cm long and 2.4 cm in diameter is installed on the smaller bracket (by welding).

Also, a rod 1.6 cm thick is screwed into the stem, which should protrude slightly above the level of the crossbar. The most difficult part in making this model is spherical shape of the discs. In general, this is a common question among gardeners and gardeners interested in how to make a homemade cultivator with reliable working elements. Without special equipment, there can only be one way - to change the shape of the disks with a hammer, forming a bowl in the central part. Further, it is important to calculate the angle of fixation of the spherical disks with respect to the direction of processing. This parameter must be adjusted using the wing screws mounted on the crossbar.

Chainsaw cultivator

This variety of homemade cultivators is also suitable for larger work. By its power, the device will not yield to some versions of mini tractors. In addition, you can make a homemade cultivator for a walk-behind tractor from a chainsaw, providing for the appropriate joints in the structure. But a more profitable solution is a fully mechanized unit with a chainsaw engine.

The base will be a cubic frame welded from corners. The power plant will be located at the transverse corners in the upper area of ​​the hull. The fuel tank can be mounted even lower using brackets. The front struts will be the supporting frame for the middle shaft. To fix the bearings of the undercarriage, the struts should be attached to the longitudinal elements. The result is a home-made walk-behind tractor with a center of gravity above the surface with a wheelbase. As wheels, you can use a rubberized roller, and the handles are made of pipes.

Electric meat grinder cultivator

In this case, the power unit is borrowed from the meat grinder, but otherwise the concept remains the same. The frame from which homemade cultivators are made for a tractor or walk-behind tractor can also become the basis for autonomous equipment. A feature of this design is the ability to quickly break up soil layers into large clods. If it is supposed to operate at low speed, then the processing will be delicate and provide a loose cover.

Two corners must be welded to the crankcase removed from the meat grinder. Two pipes are also installed to them, in which the ends should first be bent - in the future they will become handles. Wheel axles are also attached to the base of the corners. Excessively large wheels should not be chosen, because during the processing they will deliver unnecessary trouble. But small ones are also undesirable, as they fall into the soil. Accordingly, the best option is medium wheels with a diameter of 20 cm. A shaft should be machined from the assembly scrap. Using a sledgehammer or a large hammer, it is necessary to break off the nozzle of the meat grinder, which will allow you to remove the sleeve, which will take the shaft with the lug screw into the structure.

DIY motofreza

This unit is a cross between manual models and a full-fledged walk-behind tractor. If you want to get a homemade cultivator, the cutter of which carries out processing without a third-party drive, then this option will be optimal. In place of the engine, any installation with a working volume of 50 cm 3 is suitable. The milling tasks can be shifted to a structure assembled from metal strips with parameters 0.5 x 4 cm. For one milling cutter, you will need 8 elements. Next, the strips must be shaped into the letter G and connected to each other in the center by bolts so that four crosses are formed.

The supporting base will be a metal box, in which the deceleration of the gearbox should also be placed. Such a frame can be made of 0.4 cm thick plates and bearing housings. To pass the intermediate shaft at the top of the formed box, two holes should be made. The shaft will rotate in two bearings mounted in two housings welded from the plates. To adjust the position, homemade cultivators with this design are equipped with threaded rods. They can be welded to the base of the plates.

Arrow cultivator

The unit has a simple design and does not require combination with other equipment, but at the same time gives good results in tillage. The output is lancet equipment with five working paws. The basis of the structure will be formed by a beam-shaped frame, also made of steel corners. Plane-cutting paws of a lancet type are installed on it. You can take such elements from the factory motoblock KPN-4A. It is necessary to fix the cutting components so that one middle and two extreme legs are staggered. Their bundle should provide a hinged frame on the springs. The estimated processing width with such paws is 33 cm.

Cultivating disc harrow

The disc harrow can be constructed from a battery formed by 8 disks that are spherical in shape. According to the type of work, it will be a makeshift cultivator for a walk - behind tractor, the width between the cutting elements of which will be 15 cm. The harrow interacts with the frame according to the articulated principle. The length of the base can reach 130-140 cm, and the width is 65 cm. In this case, the frame uses angles with a section of 45 x 45 cm. The depth of entry into the soil is up to 10 cm, and the approximate working width is 120 cm. The advantages of such a harrow also include the ability to adjust the angle - up to 17 degrees.

Single hull plow

One of the best solutions for manufacturing auxiliary equipment for a tractor will be a single-body plow. Using it, you can plow from 0.12 to 0.2 hectares per hour of work. At the same time, the processing depth is small - only 22 cm, and the width reaches 35 cm. Homemade cultivators for a mini-tractor are made from a metal frame base. The plow can be made from channels, and the body can be borrowed from trailed attachments such as a cultivator, but with a shortened blade.

There are many structural solutions for the development of cultivators, and the choice of a particular one is determined by the needs of the future user. Material costs for the manufacture of earth-processing devices are minimal, and despite the fact that factory analogues are sometimes valued at tens of thousands of rubles. This is largely due to the fact that homemade cultivators are increasingly being used not only in private households, but also in professional farming organizations. In terms of reliability, they are slightly inferior to branded units, and in terms of the quality of the cultivation of the land, they can also surpass. You can make a cultivator with your own hands from improvised metal blanks, but the main advantage of such devices is the ability to diversify designs and, as necessary, make technical adjustments without the help of specialists.
