FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry, in particular, to tillage rollers. The roller comprises a frame, an axis and concave disks. The concave disks are mounted on the semi-axes with the possibility of their displacement in the vertical plane and fixing in the determined position. The frame of the roller is made composite with the ability to change the angle of installation of the side beams with the concave disks to the direction of motion and fixing in the determined position. Between the concave disks on the axis at an equal distance from them the packing disk is mounted. On the outer surface of the packing disk a ring is mounted. On the lateral surfaces of the ring horizontally in both directions from its axis of symmetry the semi-spiral plates are mounted at an equal distance from each other. The outer edges of the semi-spiral plates are located circumferentially of equal diameter. The semi-spiral plates are located on one side of the ring, mounted on the center of the gaps formed by the semi-spiral plates, located on one side of the ring, are mounted on the center of the gaps formed by the semi-spiral plates located on the other side of the ring.

EFFECT: constructive implementation enables to improve the quality of the formed ridge.
