Abstract:
1. A control system for an agricultural implement, the agricultural implement comprising a frame, a ground-engaging tool coupled to the frame, and an adjustment device coupled to the frame, the adjustment device configured for raising and lowering the ground-engaging tool between a transport position and a pre-selected operating depth and configured for providing a pre-selected operating pressure, the control system comprising: a position sensor configured for measuring a depth indication of an actual operating depth of the ground-engaging tool and configured for generating a corresponding position signal; a pressure sensor configured for measuring a pressure indication of an actual operating pressure and configured for generating a corresponding pressure signal; and an electronic or electro-hydraulic implement control unit configured for receiving the position signal and the pressure signal and configured for controlling the adjustment device so that the depth indication targets a depth set point that is indicative of the pre-selected operating depth, based upon, at least in part, determining whether the pressure indication is within a pre-selected pressure range.
