ABSTRACT:
The disclosure relates to an apparatus for controlling the position of a header relative to the ground surface, the apparatus including one or more pivotable shoes arranged to contact the ground and to move in dependence on changes in the ground contour. A further member secured to such a pivotable shoe includes a reflecting surface remote from the point of contact of the shoe with the ground surface. An emitter/receiver is spaced from the reflecting surface and connected to a control circuit whereby the position of the header relative to the ground may be measured by virtue of the position of the reflecting surface. The position of the header relative to the ground surface is then adjustable in dependence on the detected measurements, by means of various actuators associated with the apparatus.
