ABSTRACT:
A power winch is described which includes drive means with an output shaft, lock means to prevent reverse rotation of the shaft and a drum clutch assembly. The drum can be selectively engaged with or disengaged from the drum shaft. The lock means prevents the drum from rotating in reverse when it is engaged with the drum shaft. The power winch can be made compact and portable and can be powered by a small internal combustion engine.
