The dealer in Worland sells Kiotti if you want another alternative. I plow with my Yamaha Viking faster than a tractor but not as versatile for other jobs. The best deals on used tractors are back in Midwest, There is also another guy in Riggins Idaho that sells TYM tractors and reconditioned gray market Japanese compact tractors. As has been mentioned service is a big thing but I am sure both dealers in Powell would service a used model of their brand even if not bought from them. For what it is worth I bought a lawn tractor from the John Deere dealer in Powell and I thought they provide great service.
