Use that 1100 as a garden tractor as you want, but don't expect too much life out of the transaxle. Cast iron housings don't mean a whole lot, it's usually just an advertising point, it's the gears inside that are the problem. The 1100 was the product offered after the 800 was discontinued, other than having some common parts with a Cub Cadet Quiet Line tractor, they were little more than a large version of the Cadet line.
