Abstract
A propel system of an agricultural vehicle has an active pump displacement control system for equalizing or balancing pressure output of hydrostatic pumps of a tandem pump propel arrangement. The active pump displacement control system may include a pressure sensor(s) for determining output pressure of hydrostatic pumps and use the output pressure values within a feedback loop to provide coil input values of coils that control displacement of the hydrostatic pumps so that the pressure outputted by the hydrostatic pumps can be equalized in real-time while on the go during use of the agricultural vehicle.
