Disk harrow (mounted/trailer) BDN-2.4, Dnipropetrovsk region.

Disk harrow (mounted/trailer) BDN-2.4 . Harrowmounted disc harrow intended for resource-savingpre-sowing soil processing. Hinged disk harrow BDN-2.4. Disc harrow hinged BDN with an adjustable angle of attack up to 20 cm depth of cultivation - intended for pre-sowing and continuous cultivation of soil in fields with different mechanical composition, as well as for preparing the soil for sowing grain crops, planting fodder and technical plants, including grinding and embedding in it plant residues for refreshing meadows when using different agrotechnical schemes not clogged with stones and other obstacles, with soil resistivity up to 0.9 kgf/cm2 (0.09 MPa), hardness up to 35 kgf/cm2 (3.5 MPa), and soil moisture up to 27%. The disc harrow is aggregated with class 1.4 tractors (MTZ -80/82, YuMZ -80/82). Each row of disks has the possibility of adjusting the angle of attack from 0 to 30° and, accordingly, the working width of the disks. The greater the angle, the smaller the distance between the discs, but at the same time the traction resistance increases. Therefore, the angle must be chosen optimally, so that the unit has the opportunity to develop the working speed for the high-quality implementation of the technological process of tillage.
