ABSTRACT:
A hydraulic system for a work machine is disclosed. The hydraulic system includes a tank adapted to store a supply of fluid and a source of pressurized fluid in fluid communication with the tank. A first hydraulic actuator and a second hydraulic actuator are in fluid communication with the source of pressurized fluid. A first fluid return line is adapted to direct a return flow of fluid from the first hydraulic actuator to the tank and a second fluid return line is adapted to direct a return flow of fluid from the second hydraulic actuator to the tank. A pressure control device is disposed in the second fluid return line and is operable to selectively adjust a magnitude of fluid pressure in the second fluid return line.
