Hydraulic system for a work machine

It discloses a hydraulic system for a working machine. The hydraulic system (100) comprising a fluid suitable for storing a supply of a fluid storage tank (114) a source of pressurized fluid (112) and a fluid tank (114) in fluid communication. In fluid communication with a first hydraulic actuator (128) and a second hydraulic actuator (160) with a source of pressurized fluid (112). A first fluid return conduit (158) adapted to the fluid return from the first hydraulic actuator (128) is directed to a fluid reservoir tank (114), and a second fluid return conduit (130) adapted to from a second a hydraulic fluid actuator (160) is directed to the reflux fluid tank (114). There is provided a pressure control device (170), and the manipulable means to selectively adjust the size of the second fluid pressure in the fluid return conduit (130) in the second fluid return conduit (130).
