Disk spring harrow DAR-2, 1 DAR-2, 4 DAR-3, 0 DAR-4, 0 MTZ T-150, Kyiv region.

Main resource-saving tillage is carried out to a depth of 5 to 18 see.

They provide uniform distribution of organic fertilizers and crop residues throughout the depth of the cultivated soil layer, creating an optimal structure for plant growth, increase moisture absorption by the soil, reducing erosion, grind lumps and roll the top layer of soil to preserve moisture, and level the topography of the field.

Mounted units provide high productivity in small fields.

Aggregates are used for minimal, conservative and traditional tillage.

Units of this design combined the functions of a plow, disc harrow,husker and cultivator.

The discs are installed at the experimentally determined angles of attack and setting the axis of rotation to the horizontal, which ensures cutting of the lower layer of the soil layer and this reduces the energy consumption of soil cultivation and wear ofdiscs, ensures their self-sharpening and uniformity of the depth of cultivation.

The discs are fixed on C-shaped springs and make low-frequency oscillations in three planes, as a result of which they are independently cleaned of plant residues and soil. These springsprotect disks and bearing supports under shock loads.

The discs perform a rotational movement and this reduces their friction on the soil, which ensures fuel economy and minimal wear of the discs, compared to traditional soil cultivation technologies.

The discs have cutouts and are made with sharpening along the entire outer perimeter, which makes the aggregates work efficiently in the cultivation of heavy and hard soils, including clayey chernozems, shredding of harvest residues, and reduces the traction force of the tractor.

A significant angle of attack and setting the axis of rotation to the horizontal contributes to the ascent of the soil and plant remains and their excellent mixing.

The bearing unit uses high-quality bearings from the Lutsk Bearing Plant, which is part of the SKF corporation, a modern cassette seal and high-quality plastic lubricant, which ensures the life of two discs without disassembling the bearing unit.
