A large round baler is equipped with a pick-up mounted to the baler frame for being raised and lowered relative to the ground by operation of a hydraulic cylinder. The pick-up is maintained at a desired working height by a control arrangement including at least one height sensor which sends a signal corresponding to the instant height of the pick-up above the ground to a signal processing unit which compares the height signal with a stored value corresponding to a desired height, the signal processing unit the sending a control signal for controlling a solenoid- operated valve in such a way that the hydraulic cylinder is caused to move the pick- up in the required direction for maintaining the desired height.
