Estimating the term…
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.
A height control system for a front harvesting attachment, comprising:
A method for operating a height control system for a front harvesting attachment, wherein the front harvesting attachment comprises 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 at least one horizontal axis and are articulated on the frame, wherein the supporting arms are connected to an actuating device that is designed to pivot the supporting arms during the harvesting operation, originating from a desired position (SP) which was set before the start of a harvesting operation, between an upper end position, which delimits a deflection of the supporting arms in a 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 (SP), the method comprising adapting with a control device the desired position (SP) during the on-going 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.
