摘要:
A hydraulic system including a supply line, an implement-based control valve, an override valve supported by the implement, and a bypass line. The control valve is fluidly coupled to the supply line and configured to regulate a flow of pressurized hydraulic fluid supplied through a downstream actuator line to a hydraulic actuator of the implement. The override valve is fluidly coupled to the actuator line downstream of the control valve and includes a supply position at which the flow of pressurized hydraulic fluid from the control valve passes through the override valve to the hydraulic actuator. The override valve is actuatable to at least one override position at which the flow of pressurized hydraulic fluid from the control valve is cut-off. The bypass line is fluidly coupled between the supply line and the override valve such that a portion of the pressurized hydraulic fluid flows to the hydraulic actuator.
