BDP 3.2 disc harrow (trailer) standard for a tractor of the best MTZ, Dnipropetrovsk region.

Disk harrow (mounted) BDP 3.2.
Thedisc harrow is intended for for resource-saving pre-sowing and basic tillage for grain, technical and fodder crops, weed destruction and grinding of crop residues after harvesting crops, as well as grinding, leveling and compaction of the soil after disking.
The disc harrow is used in soil and climate zones with soil moisture up to 27% and hardness in the treated layer up to 3.5 MPa, as well as in fields with a significant amount of crop residues.

Each disc of the harrow is mounted on an individual rack and has an inclination relative to the vertical axis that allows you to adjust the angle of attack and the working width of the disc.(//tractor-service.com)

At the same time, the disc plays the role of a plowshare and a blade, which contributes to better rotation of the layer, its crushing, and also to the reduction of the traction force of the tractor.
Fixing the discs on an individual rack allows the harrow to work on soils with a large amount of plant residues and also on lands with any amount of weedy vegetation, while the winding of plant residues on the axis of the disc and clogging of the space between the discs is excluded.
The service life of harrow discs is increased by 100% due to the use of high-quality steel with boron content. Each disc has a manufacturer's stamp as proof of quality.
The train-roller is intended for mixing plant residues with soil, leveling and compacting the soil after disking.
