We get about 150in of snow here and lots of lake effect. Smaller 18-25hp move snow around here all the time pretty easy specially with blowers, issues with smaller tractors would be pushing big banks.
If you go with a front blower you need a mid PTO, on Kubota they are often standard, but have to look on each model The other consideration with a cab is if you get a rear mount can you reach through the window to crank the chute, the other option is with a cab and being a rear mount is you would need at least one remote this would eliminate you have to reach through the window, which if you get a cab to have to keep the window open kind of defeats the purpose. To me if I went rear mount I would probably get drag model instead of a push model, as in you drive straight with the drag model basically auger faces the front not the back, I wouldn't want to be backing up all winter. If possible I think I would buy a tractor with a mid pto anyways, eliminates the want or needing of it later
A lot of ways to do it and everybody's situation is different. Blades are the cheapest, front blowers are the most money. But you can always buy these things used. With that said Im not pushing snow with a blade, it creates big mounds and I don't care how good you are it always takes up lawn which means fixing it every year, also thing blades are harder on pavement or concrete. I also wanted to be in heated cab and didn't want to drive backwards. So I went with the front mount, they aren't cheap, but I did find a used front mount system for about the same price as a new rear mount, so that was a pretty good deal.
