I have a small Toro cc 2450, 2-cycle, 20 inch clearance width. It is great for fresh snow , even 15 inches high.
Used it for 4 years now. I got the one with the manual start.
Only issue is that the belt breaks every 2 years ($12-$20 to replace, depends where you get the belt, easy to change). I think my neighbour might have forced it into some ice and the belt broke 2 uses later.
Just did a 12 car driveway with 15-18 inches of snow; I took it slow so as not a break the belt; I did not have a spare handy. Was done in 2 hours. If it were 12 inches of snow, I would be done in 30 min or less.
The blades are made of rubber and it cleans to the asphalt. I mix oil to the gas 1:50 ratio. A little noisy but I have not done any maintenance in 4 years!
It throws the 12 inches of snow 20 - 30 feet away. I lift it easily (71 lbs) to put in my the back of RAV with the handles folded; I maintain more than 1 property. it also parks next to the RAV in my single car garage. The bonus is that it never clogged!
If it is good for Ottawa winter, it should be good for most people, except may be Alaska and Newfoundland!
