Abstract

There is disclosed a plough body position control device which comprises a plough frame (not shown), a plough beam (1) pivotally mounted on the plough frame and carrying a plough body (1') and in which the plough beam is capable of pivoting relative to the plough frame in response to variation in ploughing load applied to the plough body during ploughing e.g. when encountering a buried stone or other obstacle, hold-down means (3, 4) for exerting a hold-down force on the plough body (1') during ploughing and which includes a hydraulic piston/cylinder arrangement (5) to control the hold-down force exerted on the plough body: in which the overload control device comprises a pressure source (8) connected to the piston/cylinder arrangement (5) via a pressure controller (9), a sensor (10) arranged to monitor the position taken-up by the plough beam (1) relative to the plough frame and to respond to movement of the plough beam (1) with the sensor being arranged to issue corresponding sensor signals, and a processor unit (12) arranged to receive signals from the sensor (10) so as to vary the hold-down force exerted on the plough body (1') in response to variation in ploughing load applied to the plough body. <IMAGE>
