Abstract: A dynamic supplemental downforce control system for a planter row unit. The system includes closed-loop feedback circuit that cooperates with a downforce actuator to dynamically control fluid flow to the downforce actuator to maintain balance between the actual gauge wheel downforce and a desired gauge wheel downforce during planting operations.

Abstract: Systems, methods and apparatus for controlling the downforce applied to a row unit of an agricultural implement having multiple row units. A downpressure control device in fluid communication with a down chamber of the least one actuator maintains as a selected downpressure, any one of a continuous range of pressures in the downpressure chamber. Pressure in the down chamber tending to oppose pressure in the lift chamber of the at least one actuator.

Abstract: A load sensing pin disposed to receive a load applied in a direction substantially transverse to a longitudinal axis of the pin. A load sensor is substantially fixedly oriented with respect to the applied load or alternatively with respect to the pin which is rotationally restrained with respect to a support structure. The load sensor is disposed to generate a load signal corresponding to strain of the pin resulting from the applied load.
