FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machinery industry, in particular, to tillage rollers. The roller-ridge former comprises a frame, an axle (15) and concave discs (11) freely mounted on the semiaxes (8) with the possibility of their movement in the vertical plane and fixing in the given position. The roller frame is made composite with the ability to change the setting angle of the side beams (1) together with the concave discs (11) to the direction of motion. Between the concave discs (11) on the axle (15) the flat discs (16) are located at equal distance from the longitudinal axis of the roller symmetry with the ability of their movement along the axis of the roller. On the edges of flat disks (16) on the axes (19) with an equal angular pitch the planks (20) of equal length are mounted. The ends of the planks (20) mounted opposite to each other are connected by hinges. At the same the plates (20) are located at an acute angle to the axis of the roller.
