The subject of the invention refers to the rotary ploughs partially supported on the tractor, where rotary ploughs are radially fixed to several both vertically and horisontally mutually spaced off shafts. When fixing ploughs on, ploughs are spaced off on shafts but with dislocated arrangement among the shafts. The subject matter of the invention is in the new construction of the plough which is to provide that, at ploughing the soil, the conditions for deeper digging into than the standard deep ploughing are achieved, but without turning over the soil, and that the large tensile resistance of the plough is avoided. The problem is solved in the way that on the top of the sickle shaped body (1) a plough share (2) is achieved, with symmetrically slanted blades (21) and (22) arched cutting edges (23) that are wedge shaped to end in the beak (3). Rotary ploughs fixed at shafts (10) and (11), turn in the direction concurrent with the direction of movement of the traction vehicle, while the first shaft (9), but often the other as well, turn in the opposite direction while its axial rotation is often under the surface of X-X soil, due to the brackets over the supports. Herewith the deep ploughing of even up to 1 m of depth is achieved and without turning over the soil. |
