FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The tillage roller consists of an H-shaped frame, brackets, rods and rollers of a loosening and leveling type. Each rod has a nut and a spring. The ripper roller contains an axle, side discs, a hollow cylinder mounted on side discs. There are clod crushers in the form of a four-sided pyramid on the periphery of the hollow cylinder. The crushers are rigidly attached to the outer surface of the hollow cylinder in parallel circular rows along its entire length in such a way that one of the sharp edges of each crusher is directed towards the movement of the tillage roller, and the edges and tops of the crushers are directed in different directions from the geometric axis of rotation of the tillage roller. The leveling roller contains an axle, side discs, sealing plates and one-sided sharpened knives. The sealing plates are rigidly fixed to the outer surface of the side discs. One-sided sharpened knives are rigidly mounted on sealing plates and axle. One-sided sharpened knives, fixed on the axis, with a sharp edge are directed in the direction of movement, and one-sided sharpened knives, fixed on sealing plates, with a sharp edge directed counterclockwise. Rippers are located on the sealing plates, which are rigidly fixed on one side on the outer surface of the sealing plates, and on the other side are directed in different directions from the geometric axis of rotation of the leveling roller. The rippers have a sharp top and are square in cross-section.

EFFECT: invention improves tillage quality.
