Abstract
Provided is a winch apparatus including two exchangeable and interchangeable gears connecting a motor to a drum, the drum being operative to extend and retract a flexible line. By exchanging and interchanging the gears to effect a change in the ratio of the diameters of the first gear to the second gear, the torque and the linear speed of the flexible line are adjustable, permitting the same winch apparatus to move heavier loads at lower speeds, or lighter loads at higher speeds.
