It's good that you are looking around before you need the parts. I've got a 1998 Cub Cadet 3185, a hefty commercial model riding mower about half the weight of your tractor. It was not working but free, so I spent a fair amount of time digging up parts. Surprise! Most of the minor parts for your tractor are probably no longer made or available. We are talking 23 years ago here. But, if you dig, you can find some old dealers who still have some compatible parts on a back shelf, or those that are buying up old tractors and parting them out. I'd take the time to identify some sources for various things before you need them. I found some parts through the Internet at an old Western Auto store 500 miles away because they once sold Cub Cadets and still had parts left. These old Cub Cadets are pretty sturdy and run forever, but you don't want to have to junk it over a part costing a buck or two. Mine is now running and should be good for several more years before any major repair. Good luck.
