SKID STEER LOADER POWER BOOST

A construction machine includes a machine frame, a plurality of ground engaging wheels or tracks supporting the machine frame, a work implement, and a lifting linkage connected to the work implement for lifting and lowering the work implement relative to the machine frame. A position sensor is operably associated with the lifting linkage for generating a position signal representative of a position of the lifting linkage within a range of motion. A hydraulic actuator is connected to the lifting linkage for moving the lifting linkage through the range of motion. A hydraulic pressure supply system provides hydraulic pressure to the hydraulic actuator. A controller is configured to receive the position signal and to generate a control signal to vary a system relief pressure of the hydraulic pressure supply system at least in part in response to the position signal.
