Many people involved in the agricultural industry are faced with the need to carry out certain types of work every day. All of them have a pronounced seasonal nature, so the same equipment can perform completely different jobs, depending on the time of year.
The same MTZ-82 tractor, which became widespread back in the Soviet years, is actively used by farmers in the summer for plowing land and various soil cultivation. For small areas, walk-behind tractors, such as Cayman, are perfect.
However, this tractor would have remained an ordinary means of transportation if it were not for the presence of certain attachments, which allow various cultivation of the land.
One of the most popular devices of this kind is the disc harrow, which is mounted on MTZ series tractors.
This equipment is used for preliminary preparation of land before sowing.
In addition, cultivating the soil with a disc harrow allows you to rejuvenate its fertile layer, which has a positive effect on the ripening of the crop.
Equipment Features
Mounted disc harrows installed on MTZ-82 and 80 are divided according to their purpose into:
- Field. They are used for loosening the soil after row-crop work, processing plowed fields, as well as removing stubble and weeds. Some models can be equipped with special ballast boxes, which allows for deeper tillage.
- Garden. Quite lightweight harrows with high maneuverability, designed for work in vineyards and orchards. Such a disker is capable of cultivating soil to a depth of about 100 mm.
- Swamp. This is heavy equipment used for processing virgin and wetlands. The swamp harrow is able to cultivate soil to a depth of up to 200 mm.
What to look for when choosing a disk drive
The first important criterion when purchasing a disc harrow is the technical component. This should be the starting point in choosing a disk drive. Before starting to search for the right type of equipment, the future owner needs to decide on the tasks that he is going to set when purchasing this type of equipment. These tasks should be based on a systematic analysis of economic needs, taking into account the level of material support.
In addition, the technical equipment of a particular agricultural complex also plays an important role in this case. The degree of basic capacity of an individual farm should also be decisive in this matter.
Disc harrow device
The disc harrow, mounted on the MTZ-82 and 80 tractors, consists of a frame on which sections of several working bodies (disks) with a diameter of 450-510 mm and fixed on one axis are installed. The axle is fixed to the base by means of bushings in such a way that when the power unit (tractor) moves, the sections with disks rotate. All disc harrow sections have adjustable working width and attack angles.
Disc harrow design
As a rule, disk batteries are installed in several rows. The section that is closer to the tractor breaks up the soil, and the second, on the contrary, covers the soil to retain moisture. For more efficient harrowing, the front and rear battery disks are offset relative to each other's axis.
Review of popular models
Currently, the agricultural machinery market offers a wide range of diskers from both domestic and foreign manufacturers. Such an abundance of attachments can take even the most experienced tiller by surprise. Therefore, before choosing a disc harrow, it is advisable to seek help from competent practitioners in this field. Based on the results of numerous surveys, it was possible to compile a list of the most popular types of disk drives for the MTZ 82 tractor:

Factors influencing price
The following factors have a significant impact on the cost of mounted disc harrows:
- Completeness of equipment. The more complete the equipment of a mounted disc harrow, the correspondingly higher its cost.
- Territorial location of the seller. Purchasing equipment directly from the manufacturer may be cheaper, but it is worth considering that the cost of delivery will also be added to the price of the harrow, and nowadays transport services are not cheap. Accordingly, the further you are from the seller, the higher the cost of the purchased equipment.
- Manufacturer. Russian companies producing agricultural equipment offer their products at the lowest prices, but Belarusian equipment has better quality. So, the cost of a harrow will largely depend on the chosen manufacturer.
- Material. The cheaper the material used in the manufacture of the harrow, the lower the final cost of the equipment will be.
- Time of acquisition. In winter, when there is practically no agricultural work, prices for equipment decrease, and, conversely, in the spring they are much higher.
