FIELD: agriculture.

SUBSTANCE: soil-cultivating roller is a hollow cylinder equipped with an axle (1) with ribs (2) evenly spaced around the circumference connecting vertical discs (3). In the middle between the vertical disks (3), an additional disk (4) is rigidly mounted on the axis (1), the edges of which are provided with cutouts in the form of semicircles. Ribs (2) are made in the form of metal cables and are installed in cutouts. On the outer side of the ribs (2) along the generatrix of the hollow cylinder from the vertical disks (3) to the additional disk (4) there are spirals (6) made of a metal pipe with the opposite winding direction. The ends of the spirals (6) are fixed on an additional disk (4) and vertical disks (3). The distance between adjacent spiral turns (6) corresponds to the maximum size of the soil clod, specified by the agrotechnical requirements.

EFFECT: improved quality of soil rolling and braking of soil clods.
