FIELD: agricultural engineering. SUBSTANCE: device has a horizontal shaft with a set of rigidly secured disks. Cutting soil- working tools are hinged on additional axles between the disks round the periphery of the smaller diameter. The additional axles are attached to two adjacent disks. The cutting edges protrude outside the edges of the disks. The shaft is mounted on a carrier wheel. The wheel is provided with a gear for changing the height of position of the shaft for adjusting the depth of tillage or mowing height. The disks have convex-concave sectors at points of attachment of the additional axles for full coverage of the effective tillage width. EFFECT: higher efficiency. 4 cl, 5 dwg |
