Rated 5 out of 5 by from Critical part for single-handing my cat The order came in quicker than I expected, a plus. New one replaced the failed 10 year old unit and worked without any adjustments. Now I can take my time repairing the old unit for a spare. I use the autopilot every time I’m out.

Rated 5 out of 5 by from Great replacement This is a perfect replacement for a wheel drive that has seen it's better days! It's difficult if not impossible to find ALL of the replacement parts for this wheel drive assembly. This replaces the whole unit with all new parts, and worked great right out of the box.
