摘要： An agricultural machine applies liquid material to a field. Valve control signals control valves to apply the liquid material. Row pressure on the agricultural machine is sensed to identify when the valve is opened to apply the liquid material. The valve control signals are generated, based on the row pressure, to control the valves to apply the liquid material at a desired location in the field, relative to plant locations in the field.

摘要： A mobile machine includes a frame and a set of frame support elements supporting the frame. A set of ground engaging elements is mounted to the frame and movable relative to the wheels to change a depth of engagement of the ground engaging elements with the ground over which the mobile machine travels. At least one actuator drives movement of the set of ground engaging elements relative to the frame. A ground sensor is operably coupled to the mobile machine and configured to provide a ground distance signal. Ground engaging element height adjustment logic is configured to receive the ground distance signal and provide a control output to the at least one actuator to generate a height value of the ground engaging elements relative to ground.
