Abstract
A vehicle includes a chassis, an implement coupled to the chassis, a hydraulic actuator configured to move the implement relative to the chassis, a tractive element coupled to the chassis, a hydraulic motor configured to drive the tractive element to propel the vehicle, a drive pump fluidly coupled to the hydraulic motor, a charge pump coupled to the chassis and configured to provide a flow of pressurized fluid, and a valve assembly fluidly coupled to the charge pump. The valve assembly is configured to (a) direct a first portion of the flow of pressurized fluid to the drive pump and (b) selectively direct a second portion of the flow of pressurized fluid to the hydraulic actuator.
