Abstract:
A planter downforce system includes a plurality of hydraulic accumulators. Each of the plurality of hydraulic accumulators is operatively connected to a pressure line associated with a row unit of a planter. A pressure sensor is operatively connected to the pressure line. An orifice is operatively connected to the pressure line to limit flow of fluid within the pressure line to a hydraulic zero-pressure tank. A controller is operatively connected to the pressure sensor and configured to determine accumulator charge pressure of the accumulators.
