In a position-control system for a tractor-towed implement which has a lifting shaft (100) and a lifting cylinder and is vertically adjustable, via the lifting shaft (100) rotatable by the lifting cylinder, between a region of ground-working positions of differing depth and a region of transport positions of differing height and which has a transducer transmitting different signals in dependence on the particular height of the implement and having a movable part (120@C), the transducer is arranged at a distance from the lifting shaft (100), the lifting shaft (100) being connected fixedly against rotation to a pivoting arm (126) and the movable part (120a) of the transducer being connected to the pivoting arm (126) in such a way that, in the region of ground-working positions of differing depth, the range of movement of the movable transducer part (120a) is greater than the range of movement of the pivoting arm (126) on the lifting shaft (100). <IMAGE> |
