Never used one, I assumed they were just big leafblowers. So they're not really blowers then, they actually cut it up first.
In Scotland we don't get much snow, when we do we ether use a shovel, drive through it, or just wait till it melts. Some people take great pride in clearing a path from their front door to the road. F*ck knows why as it takes them a couple of hours, but it takes me 30 seconds to just wade through it. It'll melt in a week anyway.
