I have a 2015 Cub Cadet XT3-GSE riding tractor. The front wheels are 8" and the rear wheels are 12". Does anyone know where I can buy Baby Moon, or any other type of preferably metal hub cap for this tractor? Do all MTD lawn tractors have the same wheels? I'm hoping maybe a hubcap off one of their other brands might fit. Thanks for any and all info. John.
