SYSTEM AND METHOD FOR ADAPTIVELY CONTROLLING DEPTH OF GROUND-ENGAGING PLANTING ROW UNIT USING FORWARD SENSOR THAT MEASURES RESIDUE AHEAD OF ROW UNIT

Abstract: an agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. a plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. a plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. a plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. the controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.
