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 by 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 type roller contains a single horizontal axis located perpendicular to the direction of travel, side and intermediate discs mounted on the axis at regular intervals in the horizontal plane. V-shaped loosening elements are installed on the side and intermediate discs with equal angular pitch. The tops of the loosening elements are rigidly fixed on the periphery of the side and intermediate discs. The sides of the V-shaped loosening elements are directed in different directions from the geometric axis of rotation of the leveling roller.

EFFECT: invention improves tillage quality.
