FIELD: agriculture.

SUBSTANCE: tillage roller is a hollow cylinder equipped with axis (1), with ribs (2) evenly located along the circumference, installed along a helical line, connecting vertical disks (3). On both ends of axis (1) there are movably installed L-shaped fasteners (4) consisting of two rigidly connected plates. One of the plates is connected to each other by means of additional axis (5) installed with possibility of rotation, on the ends of which there are pulleys (6). Auxiliary axle (7) is installed on the other plates with possibility of rotation, at one end of which there is pulley (6), and at the other end – sprocket (8). Pulleys (6) of each attachment are interconnected by belt transmission (9). Teeth of sprocket (8) engage with ribs (2). On additional axis (5) auxiliary discs are installed. Rings (11) with toothed surface are installed on the edge of auxiliary disks. Teeth are made in the form of triangular prisms with the same height. Distance between rings (11) and the width of rings (11) are equal to the maximum size of the soil lump specified by agrotechnical requirements. Diameter of circle passing along tops of teeth of rings (11) is less than distance from axis (1) to inner surface of ribs (2).

EFFECT: higher quality of soil compaction and crumbling of soil lumps.
