Tractors, mini-tractors and tillers help to make life easier for all farmers: from small farms to powerful agricultural holdings. The main advantage of the tractor is the possibility of using trailed and attached equipment for different jobs. For example, for mowing or to prepare the field for sowing use different types of mowers.
Purpose of the mechanism
Mowers - These are mechanisms that have a wide range of tasks in agriculture and public utilities: harvesting fodder crops, harvesting, preparing the field for arable land, mowing park and house lawns, harvesting grass along roadsides. Due to high performance, simplicity and reliability of the design, the most widespread are rotary-type devices.
Did you know? The first device for mowing was invented by the Englishman brigadier of the textile factory Edwin Beard Bading. He drew this idea in the mechanism for trimming the fringe from the rolls of fabric.
The mechanism of this unit is quite simple: on a metal frame (cant) several disks are mounted, on disks there are several knives installed on hinges (usually from 2 to 8), which turn and cut the grass as the disks rotate. Knives are made of hardened steel. Since the construction is rather simple, mowers of this type are easy to maintain and, if necessary, can be repaired independently. 
Types of rotary mowers
There are several classifications mowers. Depending on the method of mowing, they are divided into:
- shearing the grass into a slope (left evenly over the area of the field);
- mulching (grinding);
- folding the cut grass into rolls.
- mounted;
- trailed.
Features of the design and principle of operation of mounted mowers
Attachments for tractors do not have their own undercarriage, it can have one or several 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. 
Rotary mounted mower can be easily connected to the tractor using a PTO and is easy to operate and maintain. These units are used for processing areas of small size, although they can be used in the fields. Comfortable when working on uneven terrain. This is the most popular type of mowers with users of motor-blocks and mini-tractors. 
How does the trailer mechanism
Trailed mower consists of a frame frame, based on pneumatic wheels. Cutting elements (discs with knives attached to them) are attached to the frame frame with sprinkles and traction mechanisms. Also on the frame are the control levers of transmission mechanisms. The third point of support is the beam of the tractor.
Did you know? The device of the rotary mower was invented in Australia in the early twentieth century.Trailed units in comparison with mounted, as a rule, have a greater working grip, require more power and, consequently, more productive. They are used in the fields of a large area.
How to install the mower on the tractor
Before installing the machine on the tractor, check all the connections and tighten all the bolts. Then, in the case of installation of attachments, connect the hinges of the tractor attachment with the connecting axes of the frame of the installed equipment. When installing a trailed mower, respectively, use a trailed mechanism. Then connect the drive (drive shaft, gear, belt or bevel gear, hydraulic drive) to the tractor PTO. 
In the presence of 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, it is necessary to make sure that the protective covers are installed securely and check the operation at idle.
Tips for choosing a model
When choosing a rotary mower for a tractor or motoblock, the following factors should be taken into account:
- types of vegetation: for harvesting plants with a hard thick stem, a more powerful aggregate is needed;
- size and relief of the field to be processed: for fields with a large area with complex terrain, trailed models are preferable;
- mowing target: it is better to take a mulch model during primary field processing, and when laying fodder hay - stacking hay in rolls;
- price: The equipment of European, American or Japanese manufacturers is of high quality, but expensive; Chinese product can be bought cheap, but the quality is not guaranteed; domestic products occupy an intermediate position and at the same time profitable availability of spare parts.
Important! Pay attention to the presence of a damper that protects the cutting device from damage in the event of a collision with a stone or a thick branch.
For private and small farms, where they work mainly with tillers and mini-tractors, the Centaur-type LX2060 mower is a good choice. This device is connected using a splined drive to the PTO, has a width of 80 cm and a cutting height of 5 cm, which is well suited for lawns. 
For large farms need more productive equipment. For example, the rotary mowers of the Polish production "Wirax", which are suitable for connection to the equipment MTZ, "Xingtai", "Jinma" and others.
For tractors MTZ-80 and MTZ-82 rotary disc mowers are suitable. Cutting the grass they carried discs, which are knives. Drives move in a different direction and the grass is cut evenly.
The best mowers for processing large fields are trailed variations, for example the Krone EasyCut 3210 CRi. They have a width of 3.14 m, they are equipped with 5 rotors, mowed grass is placed in rolls and have a capacity from 3.5 to 4.0 ha / h. 
Modern technology can significantly ease the life of the farmer, and, of course, the mechanization of labor should not be neglected. The main thing is to make the right choice, based on immediate needs and current financial opportunities.
