Micman, the Cadet snow blower attachments seem to work pretty well, I've had a 190-303 on my GT2186 for one season and it does a good job. Only time I've had feeding problems was with the snow a couple weeks ago, ground was wet and snow packed into an ice ball on the auger. It'll throw very well, and with the power of the tractor you'll burn belts before you ever lug the engine. I'd suggest looking for a used unit at a dealership, I don't think I'd go for the new price of one. Definately get tire chains as well.
We get enough snow around here that blowing it keeps from building the piles up and then later not having a place to put the snow, as well as not gouging the driveway and lawn up with a tractor or truck mounted blade.
Good luck with whatever you decide!
Pat
