A disk harrow comprises a supportive frame, disk working elements fixed on the frame with the aid of individual platelike spring legs. One end of each of the legs is made as a semiellipse turned forward as a disk working element rotates, and fixed on the frame, and the second end is fixed to a bearing assembly of the concave disk working element. The bearing assembly is arranged on the internal concave side of the disk working element. |
