Abstract
A towing winch system with fluid pressure actuated power input and winch input clutches disposed serially between the power take-off and cable drum. A controlled but variable reduced fluid pressure from a source is applied to the winch input clutches and full fluid pressure is applied to the power input clutch through a valve which opens in response to and when the pressure applied to the winch input clutches exceeds a manually selectable low or high value for inching or non-inching operation, respectively.
