Rotary mower for minitractor: design and features
Manual work in the agricultural sectornow consistently replaced by the introduction of various technical devices and specialized equipment, including homemade equipment. Some technique performs several functions at once. In agriculture, an irreplaceable tool is a rotary mower for a mini tractor. It is so popular because it can be made by hand.
Purpose and features
Rotary mower for a mini-tractor allowsfacilitate the processing of large tracts of land. Mowers of rotary type, produced by modern industry, are designed for machinery with a capacity of 12 to 25 liters. from. The construction of a mower of this type is much simpler than a segmented device. In addition, rotary equipment is safer and better tolerates loads.
If such a machine breaks down somewhere in the fields, then you can repair it yourself. And easily and quickly - in stores there are always spare parts for this equipment.
With the help of rotary mowers for a mini tractor, you canfree any territory from weeds. Also, this equipment helps in the care of the local area and lawns. For mowing hay, rotary equipment is suitable as best as possible.
Mowers for minitrator and motoblock are produced in a variety of modifications. They are made by different manufacturers. The market is segmented into Russian, Chinese or European products.
Chinese rotary mowers for minitractorsdiffer low price, but domestic products have a higher quality. European equipment is offered at an overpriced price. Therefore, the choice of many farmers falls precisely on Russian products:
- "Uralets-180".
- KR-09.
Design and operation principle
The rotary dross device is aRotating on a metal axis, disks with knives. The axis is driven by a power take-off shaft, which is always present on the mini tractor. Often, self-made rotary mowers for minitractors allow you to cut the bushes in the garden. The trailing device is very simple to install. It is suitable for both mini-tractor and motoblock. Equipment for mowing is characterized by high practicality and reliability. The main thing is not to violate the rules of exploitation.
Classification
Rotary mowing equipment, depending onfunctionality is divided into several groups. So, the device is able to lay grass in mowing. The second group is able not only to mow down, but also to grind the grass. The third group can lay it in rolls. Mowers are divided into groups and by the method of installation - there are hinged, semi-mounted, as well as trailing devices
The location of the cutting mechanism can befront, side or rear. On the mini-tractor it is possible to install a rotary aggregate, which consists of several bars. As a drive, a power take-off is used. Sometimes the torque is supplied from the driving wheels.
The equipment in question is being installedhorizontally. The connecting rod together with the knife moves in the same plane. Specialists recommend to use a Polish rotary mower for mini-tractors for small areas. One such is the Wirax L-169/04. The manufacturer offers a cardan shaft as a gift. Front hinged models, except for mowing, are able to break the earth into pens. Polish units also help to quickly process the site, but you need to select a device with several working elements.
Choose a suitable model for the required heightcutting grass, the level of productivity, the rotational speed of the knives. The advantages of rotary mowers - the presence of a damper, which protects the cutting elements from a variety of obstacles.
Semi-mounted units
These models are used most often at largesites. Such a machine is a frame with a wheel attached to it. It performs a supporting function. Also on the frame are cutting blades. Due to simple design, the price for such models is quite low.
To mount the mower to the tractor is usedexclusive use bracket. The support is carried out on the longitudinal beams on the frame, the trailing device and the support wheel. The cutting part is of the single-run type. The drive is a power take-off shaft. The equipment is raised and lowered by means of remote hydraulic cylinders.
Trailer
These models often have three cutting parts.
They are located behind, from the side or on the fronttractor. The construction is fixed to the frame of the mower. The mechanism operates according to the classical scheme - due to the power take-off shaft. This equipment is used mainly in large fields.
Attachments
This is one of the most popular frontal modelsfor mini tractors. They are applied equally effectively in the field and in small areas. These models are perfect for processing areas with an uneven surface.
Usually in such cases a rotary mower KR-09 is used to the lateral minitractor.
Shredders
It is worth mentioning one more kind of rotary mechanisms. These are choppers. The design consists of:
- Frames.
- The rotor.
- Pipeline systems.
- The drive mechanism.
The principle of operation of this unit is the following - whenthe grass is cut with rotary knives. Then it rises, where it is crushed. Further, the ground grass is fed into special storage tanks.
This design is suitable for mowing works on lawns, and she deserved the popularity of a small cost. But its only drawback - the models are not suitable for harvesting hay.
The lineup
These units are represented on the market by the followingmodels. So, "Dawn" is mounted using a reducer and brackets. The model is suitable for mowing grass, small shrubs, cereals. The width is from 70 to 80 cm. "Zarya-1" is used for processing hard-to-reach places.
"KNS-0.8 Swift" will help to mow high grass. The height of the vegetation is up to 2 meters. Compact models "KM-05" differ in width of mowing up to 50 cm.
The rotary mower KR-09 to the minitractor ismodern model. It works with various mini-tractors, such as Zubr, Dobrynia Sylach, Centaur and any others, whose capacity is up to 15 liters. from. The braid is fixed by a coupling. It comes complete with a mower. The location of the tractor is lateral.
As for the drive, the lateral rotary mowerto the minitractor is activated from the traction system of the tractor or by means of a belt drive. Due to the presence of a powerful damper, the mechanism can move as smoothly as possible. This is a good helper in the hay harvest season. One person is enough to work with the equipment. The machine weighs 60 kg, and the width of the mown grass is 1 meter.
We make the equipment by ourselves: preparation
To assemble a mowing rotor mower formini-tractor with their own hands, which will not yield to the technical characteristics of industrial models, will need skills in working with metal and a welding machine.
As a material for assembly, it is possible to use spare parts from machinery that is no longer in use. These are old frames, corners, Channel bars.
It is necessary to prepare a welding machine,an electric drill and a set of drills to it. Also need a set of wrenches and fasteners, a drive belt, pulleys and bearings, an axis for mounting wheels. You will need the wheels themselves up to 45 cm in size - you can use them from a bicycle. The metal sheet should have a thickness of up to 0.4 mm.
Manufacturing process
Frame for mowers made of metalangle or profile pipe. The size of the angle in this case is from 4 x 4 cm. Further the bearings are mounted. At the next stage, the working part is made. With the help of this design, you can mow and chop low grass. Two cutting discs are used as cutting elements. The reducer and the chain are suitable for chainsaws.
Four knives are installed on each of the disks. Elements are best used from hardened metal. For their installation, drill holes in a disk with a diameter of 6 millimeters. Elements are fixed to the tractor with a tire. This design will ensure fast processing speed.
The axis can be made of steel. Its diameter should be more than 8 millimeters. For free movement of the knives, the axle is tightened by means of a disk. The disc is mounted on the frame, where it communicates with the drive. For greater efficiency, the discs should rotate against each other.
The second version of the self-made mower
Two circles are cut from the metal. The diameter of each should be 39 centimeters. Then knives are mounted on the circle. They should rotate freely. The lower discs have a diameter of 45 centimeters - they are made from a lucher. Then take a tube with a diameter of 30 millimeters and press a bearing on it, suitable for the size. The second bearing is mounted on a pre-prepared pulley. The latter is welded to the pipe - this will allow you to fix the disks and knives on the shaft axis.
The frame is assembled from a metal corner using a welding machine. Specialists recommend making a protective cover before assembling the structure.
This mower can operate at speeds up to 10kilometers per hour. With these turns, the grass is cut within a radius of 7 centimeters from the circle. The device will easily remove weeds, mow grass, help to remove agricultural crops.
How to connect a mower and a motoblock
How to install a rotary mower on a minitractor? Very simple. First, the device is put into reverse mode. Then, the coupling unit is installed in the socket for uncoupling. Then the connection is locked with pivots. The device is ready for operation.
Conclusion
So, we found out what a rotary mower is forminitractor. As you can see, this is a very useful tool in agriculture. It greatly facilitates the work. And you can buy similar equipment at a price of 10-15 thousand rubles, which is very acceptable.
