So, I'm looking for a good 2 stage snowblower, mainly because my concrete is in poor condition and on a slope. It was a pain in the butt to use my toro single stage on it last year.. It will be getting a new home at my grandma's her driveway concrete is in amazing condition and perfectly flat. Ideal conditions. Is there any particular models I should avoid or any that I should consider more? Anyone in NE ohio have a reliable one they want to sell me?
