Abstract

Hydraulic control is for a tractor-drawn swivel plough and a double-acting swivel cylinder (1) and a control element (2) to automatically actuate the actuator piston (52) in this cylinder. The control element is, at one side, connected to an accumulator (4) and on the other side, connected by one line (12) only to a hydraulic pump (13) and reservoir (14) via a reversing valve (15). It also has a valve (23) which, under the action of hydraulic pressure, closes or opens a line (28) connecting the two ends of the actuating cylinder on either side of the differential piston. The accumulator may be connected (25) with one end (29) of the cylinder via a pressure-operated valve (20).
