<p>A reverse drive for a small vehicle includes a primary driven gear through which an external motor imparts a rotary motion to a first shaft. A worm gear is mounted on and rotates with the first shaft. A worm wheel is mounted on and rotates with a second. shaft. The worm wheel engages and is rotated by the worm gear with a clear reduction being effected through engagement of the worm gear and the worm wheel so that the second shaft rotates at a slower speed than the first shaft. A clutch is mounted on the second end of the second shaft, which can be moved between an engaged position and a disengaged position.</p> |
