</font><font color="blue" class="small">( I'm a little concerned about it as the driveway is gravel and has some rocks on it that I'm fairly certain would be launched through that blower like a machine gun.)</font>
This is why I didn't get a snow blower at all. I have a self propelled snow blower (7 hp dual type) and last year when it twice took three days for the guys who are supposed to plow us out to get around to us (not that they were slacking, just we are too far down their list of people to plow out), I decided to go after the snow with the blower. Well it turns out that when you have 32" of snow on 2/3 of a mile of driveway then that snowblower is not the right tool for the job. It died game, though, bending it's impeller on a rock I didn't see. I knew there were rocks on the driveway so I kept the chute pointed away from anything I didn't want to nail with an ejected rock. But this rock took out the snowblower.
So I went for a tractor with a quick-attach loader so I can use a blade to plow high and low, and the bucket to dig in case the berm at the end of the drive that the State builds for us is _that_ big.
