Zusammenfassung:	A hydraulically controlled towing winch comprises two winch clutches adapted to rotate a cable drum in opposite directions by selective disengagement of one of the clutches. A normally disengaged input clutch is adapted to selectively couple a power input shaft to a bevel gear arrangement of the winch mechanism for operation thereof. A single lever control system may be utilized to selectively control the actuation of the input and winch clutches to place the winch in the following modes of operation: "Reel-out" wherein the input clutch is engaged and only one of the winch clutches is disengaged to pay-out the cable by rotating the drum in a first direction; "Reel-in" wherein the input clutch is engaged and only the other one of the winch clutches is disengaged to rotate the cable drum in an opposite direction; and "Free-spool" wherein both of the winch clutches are disengaged to permit the drum to rotate freely.
