Body of the plough contains a blade, the surface of which is made of four vertically arranged steps, the first of which is a step with a field edge. Lengths of the projections of the risers on the vertical planes, i.e. the protrusion of the surface of the first stage relative to the second, the second – relative to the third, third – relative to the fourth, held perpendicular to the surfaces of the steps, is 8…10 mm. Surfaces of the risers of the stepped waste dump are arranged at an angle of 45° relative to vertical planes drawn perpendicular to the surfaces of the steps.EFFECT: high-quality loosening of the arable layer of repacked old-cultivated soils is provided.3 cl, 2 dwg
