ABSTRACT:
In a sensing device for detecting the distance of a vehicle or work device from structures that can be sensed mechanically, in particular plant stands, plant rows, soil structures, ploughing furrows or the like, with a rod-shaped, resilient sensing feeler which has a freely movable sensing end and at a distance therefrom is fixed rigidly to a housing, and an electrical measuring system which detects a change in location of the sensing end in respect of the holder and generates a measuring signal dependent on the change in location, the sensing feeler has at a distance from its fixing location a permanent magnet whose magnetic field is detected by a field-sensitive sensor with a fixed location in respect of the fixing location of the sensing feeler, which sensor generates an electrical signal dependent on the distance between the permanent magnet and the sensor.
