Does the large worm gear directly drive the wheel or does it drive the planerty. I see the planetary system but I have no idea what it's for or what it's driving.

Let me try and rephrase Matt's comment. The worm drives the worm gear. The worm gear is on a common shaft with the sun or center gear of the planetary system. The planet gears are fixed to the wheel. The outer ring gear is fixed to the frame or gear box and does not rotate. The planet gears are meshed with both the sun gear and the ring gear. As the sun gear turns, the planet gears both rotate and move forwards (or backwards, depending on your definition). Since the planet gear shafts are solidly mounted to the wheel, it too must move forward at the same rate as the planet gears. What makes this confusing is that the wheel is mounted on the same shaft as the sum and worm gears, but is not connected to it. The shaft just acts as an axel in this case. A very compact system, but it can be kind of confusing if you're trying to figure it out.
