ABSTRACT OF THE DISCLOSURE A winch includes a direct current reversible motor operable to drive a gear train to wind or unwind cable from a drum and also includes first and second clutch mechanisms in the gear train that provide respectively (1) internal loading of the winch to prohibit undesirable unwinding of cable and (2) infinite clutch control between free wheeling operation and direct gear train drive of the winch. The first clutch mechanism is a sprag clutch which is operated against a brake load built into the winch. The second clutch mechanism includes clutch plates which are engaged proportional to the force of a thrust bearing controlled by a manually operated handle.
