Abstract
A hydraulic system and method for service mode on a work machine is operatively coupled to a cutting element for felling trees. The hydraulic system comprises a hydraulic motor, a hydraulic pump, a feed actuator, a feed line, a directional control valve, a voltage battery, and a controller. The hydraulic motor is coupled to the hydraulic circuit for operating the cutting element. The hydraulic pump is operable to supply pressurized fluid to the hydraulic motor. The feed actuator extends or retracts the cutting element. The feed line is coupled to the hydraulic actuator. The directional control valve is located on the feed line of the feed actuator. The controller receives a cutting element service mode signal, moves the directional control valve to pressure the feed line for extending the cutting element where the valve is powered by the voltage battery upon receiving the cutting element service mode signal.
