FIELD: agriculture.

SUBSTANCE: suspension of soil-cultivating working bodies contains a working body, a support roller, a parallelogram mechanism connected to the frame by a hinge by means of shock absorbers and adjustable screws. The free ends of the lugs of the track roller are pivotally connected to the lugs of the parallelogram mechanism. A stepper motor with a gear wheel is fixed on the bracket of the working body, which engages with an arc-wise toothed bar rigidly fixed on the track roller lugs, the center of the pitch radius of which is located on the axial line of the hinge for attaching the track roller lugs. The radius of the pitch circle of the gear wheel is less than the radius of the toothed bar, and a lock is located at its crown.

EFFECT: reduced labor intensity of setting the required sowing depth (tillage).
