Cub Cadet Specialties are a great source for Cub Cadet parts. As said for being high priced, I believe that can be said about auto parts stores as well. Some places will have a part cheaper than one store might be. You have to shop around, for sure! Most of the prices are directly from Cub Cadet to begin with, and they also don't like to fool around with used parts too awful much. I can't say I don't blame them either.
The site has been one of the better, user friendly, and easy to navigate parts site on the web, hands down. This summer I spent a fair amount on items for the 72, and the customer service is A-1! I hope Cub Cadet Specialties can reopen at a later date.
