Abstract
A control system for an agricultural implement is disclosed. The control system includes a position sensor configured to measure a depth indication of an actual operating depth of a ground-engaging tool and configured to generate a corresponding position signal. A pressure sensor configured to measure a pressure indication of an actual operating pressure and configured to generate a corresponding pressure signal. An implement control unit configured to receive the position signal and the pressure signal and configured to control an adjustment device so that the depth indication targets a depth set point that is indicative of the pre-selected operating depth provided that the pressure indication is within a pre-selected pressure range.
