All about the rotary mower for the tractor. Rotary mowers agramak Production of rotary mowers
The GARDEN SCOUT AGRICULTURAL MACHINERY CO.LTD plant has its own production line of RM-1 rotary mowers, which are supplied to Russia in large quantities and are in great demand. The factory produces about 5,000 units of mowers per month. These mounted mowers are supplied to Russia, Ukraine, Belarus and Armenia by the Scout company. The Garden Scout factory is one of the largest and most reliable suppliers of small agricultural equipment in China.
The production culture and quality control are very highly developed. A large engineering department monitors the work of each assembler, develops technological maps and monitors compliance with work rules on the production line.
The production of mounted mowers includes full cycle- from turning gears and shafts, pressing molds for discs and producing working parts (knives). At each stage, a quality audit and control over the conveyor employees are mandatory.
The production of mower discs involves stamping metal circles from a sheet the right size. This is done by a huge press machine.
As a result, ready-made metal discs move to the next stage.
They are then stamped according to technological map and drawings. Holes are drilled in them - for landing and for working parts.
The frames and discs of the mowers are then transferred to the paint shop and undergo a drying process.
Then the mowers are equipped with fasteners and packed in cardboard boxes and go for export. Fastening and driving elements may be different. This depends on the model of equipment for which the mower is intended. For example, for Scout tractors, this rotary mower is equipped with hydraulic hoses and a hydraulic cylinder. For heavy diesel walk-behind tractors- special fasteners.
There are several other factories in China that produce this model of mower, but their quality is very low due to the lack of production culture and quality control. Beware of fakes!
And walk-behind tractors help make life much easier for all farmers: from small farms to powerful agricultural holdings. The main advantage of the tractor is the ability to use trailed and mounted equipment for various works. For example, for mowing or preparing a field for sowing, they use various types.
Purpose of the mechanism
Mowers- these are mechanisms that have a wide range of tasks in agriculture and municipal services: harvesting, harvesting, preparing fields for arable land, mowing parks and house buildings, cleaning along roadsides. Due to their high performance, simplicity and reliability of design, rotor-type devices are most widely used.
Did you know? The first mowing device was invented by the English textile factory foreman Edwin Beard Bading. He got this idea from a mechanism for trimming fringe from rolls of fabric.
The mechanism of this unit is quite simple: several disks are mounted on a metal frame (beam), several knives (usually from 2 to 8) are mounted on the disks on hinges, which, when the disks rotate, unfold and cut the grass. Knives are made of hardened steel. Since the design is quite simple, this type is easy to maintain and, if necessary, can be repaired independently.
Types of rotary mowers
There are several classifications of mowers. Depending on the mowing method, they are divided into:
- cutting the grass into a slope (leaving it evenly over the field area);
- mulching (crushing);
- folding the mown grass into windrows.
- mounted;
- trailed
Features of the design and operating principle of the mounted mower
Attachments for tractors does not have its own running gear; it may have one or more support wheels, but only a small part of the weight is transferred to them. Therefore, these are usually mechanisms of relatively low weight and performance. 
The mounted rotary mower is easily connected to the mower using a PTO and is easy to operate and maintain. These units are used to process areas small size, although they can also be used in the fields. Convenient when working on uneven terrain. This is the most popular type of mower among users and mini tractors. 
How does the towing mechanism work?
A trailed mower consists of a frame frame supported by pneumatic wheels. Cutting elements (disks with knives attached to them) are attached to the frame frame with trusses and traction mechanisms. Also on the frame are control levers for transmission mechanisms. The third support point is the tractor beam.
Did you know? The rotary mower was invented in Australia at the beginning of the twentieth century.
Trailed units, compared to mounted ones, usually have a larger working grip, require more power and, accordingly, are more productive. They are used in the fields large area.
How to install a mower on a tractor
Before installing the unit on the tractor, all connections must be checked and all bolts must be tightened. Then, if installed, connect the rods attachment tractor with connecting axles of the frame of the installed equipment. When installing a trailed mower, accordingly, a trailed mechanism is used. Then connect the drive ( cardan shaft, gear, belt or bevel drive, hydraulic drive) to the tractor PTO. 
If there are hydraulic devices that provide vertical and horizontal movement of the mower, they are connected to the outputs of the hydraulic system of the base unit.
Important! Before starting work, you must ensure that the installation is secure. protective covers and check idle speed.
When choosing a rotary mower for a tractor or walk-behind tractor, you need to take into account the following factors:
- types of vegetation: to harvest plants with hard, thick stems, a more powerful unit is needed;
- size and relief of the cultivated field: for large fields with complex terrain, trailed models are preferable;
- purpose of mowing: when initially cultivating a field, it is better to take a model; when preparing fodder hay, it is better to take a model that lays hay in windrows;
- price: equipment from European, American or Japanese manufacturers is of high quality, but expensive; a Chinese product can be bought inexpensively, but the quality is not guaranteed; domestic products occupy an intermediate position and at the same time benefit from the availability of spare parts.

MTZ tractor with rotary mower
Mowers for MTZ are produced by the Belarusian Tractor Plant, as well as imported and domestic companies. Among various models The easiest to operate and maintain is the rotary one. In this article we will discuss the most interesting models, consider how a rotary mower for MTZ works, positive and negative reviews from owners about the KRN and KRR models. Videos and photos will help the reader understand the models in more detail.
Purpose of the mower for MTZ
Rotary mower allows the owners of the MTZ tractor to perform a number of tasks: prepare hay for animal feed, remove grass before cultivating the soil or planting, maintaining order along the highway and forest belt. You can find a mower in municipal and forestry. But the main use is in agricultural complexes and private estates.
According to the method of aggregation from the MTZ tractor, several types of rotary mowers are distinguished:
- Mounted (have a front front mount);
- Semi-mounted (attached to the side of the tractor);
- Trailed (attached to the frame at the back).
According to the mowing method, rotary mowers can chop the grass, cut it and lay it in even shafts, cut it into a mow (leave it evenly throughout the entire field). For farmers who need to make hay for livestock feed, it is more profitable to choose a model with grass placed in shafts. This will make it easier to later collect it with a pitchfork and put it in stacks.
If a mower for MTZ is needed to cut grass along roads or in fields before cutting them, then mulching models will be optimal. The chopped grass does not need to be removed, it will additional source feeding cultivated plants and will make the soil lighter.
Rotary disc mowers for MTZ 80/82 tractors have high performance and are suitable for farmers with large lands. Grass cutting is carried out by discs on which knives are located. During movement, the discs begin to spin and the knives on movable hinges straighten. The discs move in different directions and the grass is cut evenly.
The disc rotor model is convenient for cultivating meadows with uneven surface, as well as for marshy and clogged areas. The mower is protected on the top sides by a metal casing, which makes it safe to use.Rotary mower models
Rotary mowers for MTZ 80/82 are produced at various enterprises. The licensed model of the Belarusian Tractor Plant is called KRN (mounted rotary mower). But Chinese, Japanese, Russian manufacturers offer equipment with a similar aggregation system and they are also suitable for MTZ 80/82 tractors. Let's take a closer look at the most popular models and reviews about them.
SRC model for MTZ
The KRN-2.1 model was developed in compliance with the norms of tradition, but at the same time, new technologies were used in the design. You can see it in more detail in the video. The video shows what the equipment looks like. In the video you can also see how the equipment works. In terms of its performance indicators, the KRN is superior to all known analogues, as it was developed specifically for the MTZ 80\82 tractor.
Currently, two types of KRN models are produced: 2.1 m and 2.1b. They differ in configuration. The equipment is suitable for harvesting fallen, fresh thick grass, bushes, weeds or residues from corn and sunflowers. After mowing, the grass is laid in an even bevel, which can then be easily dried and removed.
Among the advantages and features of the CRN, the following stand out:
- The cutting elements have a modern protective device. It improves productivity and expands functionality. Its peculiarity is that it slopes away from the obstacle by 45 degrees. The knives will not become dull and the work will be continuous.
- The number of knives in China 2.1 is 8 pieces. They are made of durable steel, so they will last for many years.
- All mowers are tested in a test mode before entering the store. Therefore, products with minor defects or defects in work will not reach the buyer.
- The gearbox housing is reinforced and the working parts are sealed.
- Suitable for tractors with power from 1.4: MTZ 80, 82, LTZ 55.
