Electrohydraulic implement pressure cutoff
An electrohydraulic implement pressure cutoff system is disclosed that includes a pump, one or more hydraulic functions, at least one valve, sensors and control unit. The pump powers the functions, and the valves control flow between the pump and their associated function. The sensor readings indicate system parameters. The control unit receives the readings and controls the valves. When the readings indicate a function is at or beyond a threshold, the control unit closes the associated valve to prevent flow to or from that function. The sensors can be pressure, position or other types of sensors. Operator control signals can be provided to control the functions. When the readings indicate a function is at or beyond a threshold in a stalled direction and the operator signals keep commanding the function in the stalled direction, the control unit can close the associated valve regardless of the operator signals.
