denny,
I assume you are talking about the 2210. While I can't answer the tire question, I can help with the snowblower. The good news is that it will fit on the 2210, the bad news is that the quick-tach will not /forums/images/graemlins/frown.gif. You are going to need the following:
Front Quick Hitch (retail $500 -- I paid $432), Front PTO Shaft ($retail $194 -- I paid $168), Implement Drive (retail $180 -- I paid $156).
Other than that the tractor is a bit longer but the joystick control sure beats the heck out of the turn-signal stalk ones.
