Invention herewith described refers to the mechanism for the soil tillage for attaching to ploughs that consists of the rotating roller (8) with surfaced pipes (10 and 11), which is via pins with the bearing (9) and the bearing (29) respectively connected with the side brackets (12) and the bracket (30) respectively, onto which is at the top welded the square tube (7). Onto the square tube (7) there are drawn the square tube segments (6) and the segments (32) respectively fastened with the bolts (13) and the bolts (31) respectively. On the square segments (6) and the segments (32) respectively, there are welded the square tubes (14) and the tubes (33) respectively whereat onto the square tube (14) there is drawn the larger square tube (5) fastened with the bolt (15), and onto the square tube (33) there is drawn the larger square tube (35) fastened with the bolt (34). The larger square tube (5) through the pin (18) is pivotally connected with the square tube (19) onto which is drawn and with the bolt (20) fastened the square tube (1) which is welded to the plate-like bracket (27), which is by means of the bolts (26) with the bent bars (28) mounted on the plough beam, while the larger square tube (35) is through the pin (36) pivotally connected with the square tube (37), onto which there is drawn and fixed with the bolt (38) the square tube (39). The square tube (39) is welded to the plate-like bracket (40) which is by means of bolts (42) with the bent bars (41) fastened to the plough beam. Onto the larger square tube (5) from the upper side laterally there is welded the square tube (16) with the pin (17) that connects the hydraulic cylinder (21) to the pin (24) which is attached to the square tube (1), and onto the larger square tube (35) from the bottom, sideways there is welded the square tube (4) with the pin (3) which connects the hydraulic cylinder (2) with the pin (43) which is fixed to the square tube (39). The hydraulic cylinders (21 and 2) are connected by h
