ABSTRACT A hydraulic control circuit for a hydraulic on-vehicle winch comprises a winch control circuit interposed between a main circuit pressure inlet and the hydraulic connectors on the winch and governed by a pilot-operated directional valve. When a reel-out pilot valve shifts the pilot-operated directional valve, hydraulic flow to a reel-out port is permitted while flow to a reel-in port is obstructed. Conversely, when a reel-in pilot valve shifts the pilot-operated directional valve, hydraulic flow to the reel-in port is permitted while flow to the reel-out port is obstructed. A selectively configurable enabling circuit is interposed between the main circuit pressure inlet and the winch control circuit. In an enabling configuration, hydraulic flow from the main circuit pressure inlet to the pilot-operated directional valve, the reel-out pilot valve and the reel-in pilot valve is permitted. In a disabling configuration in which hydraulic flow to the pilot-operated directional valve is obstructed. Date Recue/Date Received 2020-12-04
