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 installed with the possibility of rotation separately from the vertical disks (4). On the axis (1) of the hollow cylinder (2), composite wedge pulleys (9) are rigidly mounted with the possibility of adjusting the distance between the cheeks of the pulleys (9). On the surface of the smooth cylinder (5), annular grooves (10) of a wedge shape are made, connected by V-belts (11) with the pulleys (9). On the axis (1) of the hollow cylinder (2), debalancers (12) are installed.

EFFECT: quality of soil rolling and crumbling of soil lumps is improved.
