Manual work in the agricultural industry is now gradually superseded by the introduction of various technical devices and specialized equipment, including home-made. Some technology performs several functions at once. In agriculture, a rotary mower for a mini tractor is an indispensable tool. It is so popular also because it can be made with your own hands.
Purpose and features
The rotary mower for a minitractor allows to facilitate work on processing large tracts of land. Rotary- type mowing machines manufactured by modern industry are designed for machines with a capacity of 12 to 25 liters. from. The design of this type of mower is much simpler than a segment device. In addition, rotary equipment is safer and better tolerated.
If such a machine breaks down somewhere in the fields, then you can fix it yourself. And it’s easy and fast - there are always spare parts for this equipment in stores.
With the help of rotary mowers for a mini tractor, you can free any area of ​​weeds. Also, this equipment helps in the care of the local area and lawns. For mowing hay rotary equipment is perfectly suited.
Mowers for mini tractors and walk-behind tractors are produced in a wide variety of modifications. They are made by different manufacturers. The market is segmented into Russian, Chinese or European products.
Chinese rotary mowers for mini tractors are notable for their low price, but domestic products are of higher quality. European equipment is offered at an overpriced price. Therefore, the choice of many farmers falls precisely on Russian products:
Design and principle of operation
The rotary mowing device is a disk with knives rotating on a metal axis. The axis is driven by a power take-off shaft, which is necessarily available on the mini-tractor. Often, homemade rotary mowers for mini tractors allow you to cut bushes in the garden. The hitch is very easy to install. It fits both a mini-tractor and a walk-behind tractor. Mowing equipment is highly practical and reliable. The main thing is not to violate the rules of operation.
Classification
Depending on the functionality, rotary mowing equipment is divided into several groups. So, the device is able to lay grass in the mowing. The second group is capable of not only mowing, but also chopping the grass. The third group can stack it in rolls. Mowers are divided into groups and according to the method of installation - there are mounted, semi-mounted, and also trailed devices
The location of the cutting mechanism may be front, side or rear. On a mini-tractor, you can install a rotary unit, which consists of several bars. A power take -off is used as a drive . Sometimes torque is supplied from the drive wheels.
The equipment in question is mounted horizontally. The connecting rod with the knife moves in the same plane. Experts recommend applying a Polish rotary mower to a mini tractor for processing small areas. One such is the Wirax L-169/04. The manufacturer offers a driveshaft as a gift. Front mounted models, in addition to mowing, are able to break the ground into corrals. Polish units will also help to quickly process the site, but you need to select a device with several work items.
A suitable model is selected according to the required cutting height of the grass, the level of productivity, the frequency of rotation of the knives. The advantages of rotary mowers are the presence of a damper that protects the cutting elements from a variety of obstacles.
Semi-mounted units
These models are used most often in large areas. Such a machine is a frame with a wheel mounted on it. It performs a supporting function. Also, cutting discs are installed on the frame. Due to the simple design, the price of such models is quite low.
A special bracket is used to mount the mower to the tractor. The support is carried out on the longitudinal beams on the frame, the towing device and the support wheel. The cutting part is a single-run type. As a drive - a power take-off shaft. The equipment rises and falls by means of remote hydraulic cylinders.
Trailer car
These models often have three cutting parts.
They are located at the rear, side or front of the tractor. The design is mounted on the frame of the mower. The mechanism works according to the classical scheme - due to the power take-off shaft. This equipment is mainly used in large fields.
Attachments
This is one of the most popular front models for mini tractors. Apply them equally effectively in the field and in small areas. These models are perfect for processing areas with uneven surfaces.
Typically, in such cases, a rotary mower KR-09 is used to the side minitractor.
Choppers
It is worth telling about another type of rotor mechanisms. These are choppers. The design consists of:
- Frames.
- Rotor.
- Piping systems.
- Drive gear.
The principle of operation of this unit is as follows - when moving, the grass is cut with rotary knives. Then it rises up, where it is crushed. Next, the crushed grass is fed into special storage tanks.
This design is suitable for mowing work on the lawns, and it earned popularity for a small cost. But its only minus is that the models are not suitable for haymaking.
The lineup
These units are represented on the market by the following models. So, “Dawn” is mounted using a gearbox and brackets. The model is suitable for mowing grass, small shrubs, crops. Width is from 70 to 80 cm. “Dawn-1” is used for processing hard-to-reach spots.
“KNS-0.8 Swift” will help to mow tall grass. The height of the vegetation is up to 2 meters. The compact “KM-05” models have a mowing width of up to 50 cm.
The KR-09 rotary mower to a minitractor is a modern model. She works with various mini-tractors, such as “Bison”, “Dobrynya Strongman”, “Centaur” and any others with a capacity of up to 15 liters. from. Fixed braid hitch. It comes with a mower. The location relative to the tractor is lateral.
As for the drive, the side rotary mower to the minitractor is driven by the tractor's clutch system 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 unit weighs 60 kg, and the width of the mowed grass is 1 meter.
Do-it-yourself equipment: preparation
To assemble a mowing rotary mower for a mini tractor with your own hands, which will not be inferior in technical characteristics to industrial models, you will need skills in working with metal and a welding machine.
As a material for assembly, you can use spare parts from equipment that is no longer in operation. These are old frames, corners, channel.
It is necessary to prepare a welding machine, an electric drill and a set of drills for it. You will also need a set of wrenches and fasteners, a drive belt, pulleys and bearings, an axle for mounting wheels. You will need the wheels themselves up to 45 cm in size - you can use it from a bicycle. The sheet of metal should have a thickness of up to 0.4 mm.
Manufacturing process
The frame for the mower is made of a metal corner or profile pipe. The angle size in this case is from 4 x 4 cm. Next, the bearings are mounted. At the next stage, the working part is made. With this design, you can mow and chop low grass. As cutting elements, 2 discs from the seeder are used. The gearbox and chain are suitable for chainsaws.
4 knives are installed on each of the disks. Elements are best used in hardened metal. To install them, drill holes in the disk with a diameter of 6 millimeters. Elements are fixed to the tractor using a splint. This design will provide fast processing speed.
The axis can be made of steel. Its diameter should be more than 8 millimeters. For the free movement of the knives, the axis is tightened with a disc. The disk is mounted on the frame, where it communicates with the drive. For greater efficiency, the discs should rotate opposite each other.
The second version of a homemade mower
2 circles are cut out of metal. The diameter of each should be 39 centimeters. Next, knives are mounted on the circle. They must rotate freely. The lower disks have a diameter of 45 centimeters - they are made from a scoop. Then they take a pipe with a diameter of 30 millimeters and press in a bearing that is suitable in size. The second bearing is mounted on a pre-prepared pulley. The latter is welded to the pipe - this will allow fixing discs and knives on the shaft axis.
The frame is assembled from a metal corner using a welding machine. Experts recommend making a protective casing before assembling the structure.
This mower can operate at speeds up to 10 kilometers per hour. With these revolutions, the grass is mowed within a radius of 7 centimeters from the circle. The device will easily remove weeds, mow grass, help to remove crops.
How to connect a mower and a walk-behind tractor
How to install a rotary mower on a mini tractor? Very simple. First of all, the device is put into reverse mode. Next, a coupling unit is installed in the release slot. Then the connection is locked with pivots. The device is ready for use.
Conclusion
So, we found out what a rotary mower for a mini tractor is. As you can see, this is a very useful tool in agriculture. It greatly facilitates the work. And you can buy such equipment at a price of 10-15 thousand rubles, which is very acceptable.
