摘要:
A height control system for a front harvesting attachment, comprising a frame, at least one crop pick-up device, and a ground-conforming cutterbar which is situated on a plurality of supporting arms that can pivot about a horizontal axis and are articulated on the frame. The supporting arms can be pivoted, originating from a desired position to be set before the start of a harvesting operation, between an upper end position, which delimits a deflection of the supporting arms in the direction of the crop pick-up device, and a lower end position, wherein the upper end position has a first clearance and the lower end position has a second clearance from the desired position, wherein the desired position can be adapted, during the harvesting operation, to changing harvesting conditions and/or operating conditions depending on a deflection of the cutterbar, in order to minimize the first clearance and maximize the second clearance.
