System and method for controlling an agricultural implement during the performance of a tillage operation

A method for controlling a tillage operation with respect to soil in a field being performed with an implement comprising a frame and a ground-engaging tool pivotally coupled to the frame such that the ground-engaging tool is movable between a retracted position and an extended position relative to the frame, the method comprising:

• controlling, by one or more computing devices, an operation of a control valve such that the control valve provides flow to an actuator coupled to the frame of the implement such that the actuator biases the ground-engaging tool towards the extended position;
• determining, by the one or more computing devices, at least one of an actuator position of the actuator or a load value indicative of a force applied by the ground-engaging tool against the soil during the tillage operation;
• and
• adjusting, by the one or more computing devices, a reset pressure associated with an adjustable relief valve based on the at least one of the actuator position or the load value, the adjustable relief valve being configured to permit flow out of the actuator when a fluid pressure of the actuator exceeds the reset pressure such that the actuator permits the ground-engaging tool to pivot towards the retracted position.
