repeated harrowing for technical crops, stubble processing (collection ofstraw in swathes).
BP-12 and its designs are modularized with tractors of traction class 1, 44, 0 t with pressure in the hydraulic system of the rear mounted unit up to 16 MPa (160 atm).The purpose of the harrow provides - high-quality processing of the fertile soil layer, effective destruction of weeds, creation of a loose mulching layer on the surface of the field, accumulation and prevention of moisture evaporation.
The vibrational effect of the spring harrow on the soil provides high-quality crumbling of the soil and prevents it from clogging.
The inclination of the spring teeth is calibrated from 15 degrees to 90 degrees. reducing the angle of inclination of the teeth reduces soil mixing and establishes a gentle mode of influence on cultivated crops. widening of the angle of inclination strengthens the harrowing process.
