FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The tillage roller contains a hollow cylinder (2) equipped with an axis (1) with ribs (3) evenly spaced around the circumference. The ribs (3) are installed in a helical line and connect the vertical disks (4). Inside the hollow cylinder (2), a smooth cylinder (5) is installed, whose diameter is less than the radius of the hollow cylinder (2). The smooth cylinder (5) is equipped with an axis (6) mounted in bearings on tangs (7) on the axis (1) of the hollow cylinder (2). The axis (1) of the hollow cylinder (2) is mounted in the bearing supports (8) with the possibility of rotation separately from the vertical disks (4). On the axis (1) of the hollow cylinder (2), pulleys (9) are rigidly installed. On the surface of the smooth cylinder (5), annular grooves (10) are made, connected by belts (11) with pulleys (9). On the axis (1) of the hollow cylinder (2), debalancers (12) are installed at equal distances from each other. EFFECT: improved quality of soil rolling and crumbling of soil lumps.
