Winch assembly including clutch mechanism

A winch assembly includes a housing member, a drum rotatably coupled to the housing member, a drive shaft extending through the drum and into the housing member, a gear train located within the housing member, and an actuation mechanism. The gear train includes a sun gear driven by the drive shaft, a ring gear, and a planetary gear assembly driven by the sun gear and including a planetary gear rotatably coupled to a carrier plate and engaged with the ring gear. The actuation mechanism includes a locking member displaceable between first and second positions and a biasing member having a radially extending arm engaged with the locking member to provide displacement between the first and second positions. The locking member rotationally fixes the ring gear relative to the housing member in the first position and allows relative rotation between the ring gear and the housing member in the second position.
