A soil tillage entity comprises at least two essentially horizontal beams (14a, 14b) intended to be arranged at an angle to the direction of travel during soil tillage, at least one disc entity (16a, 16b) with a disc (18a, 18b) for soil tillage arranged on the respective beam (14a, 14b), wherein the said discs (18a, 18b) are arranged essentially behind one another in the direction of travel for interacting soil tillage, and wherein the angle (a, a') of at least one of the discs relative to the direction of travel is adjustable. In accordance with the invention, a turning device (21a) is adapted to turn at least one of the disc entities (16a, 16b), together or by itself, around an essentially horizontal axle (22a, 22b) for adjustment of the tillage angle (a, ss; a', ss') of the discs, and that a displacing device (21b) is adapted to displace at least one of the disc entities (16a, 16b) essentially along the lengthwise extension of the said beam (14a, 14b), for adjustment of the tillage position (L) of the discs relative to one another, wherein the axle of rotation (22a, 22b) of the disc entity (16a, 16b) and the axis of rotation (A) of its disc (18a, 18b) are not parallel. The invention also relates to agricultural machine comprising such a soil tillage entity. |
