Heck I'd just get the 7 foot blade and chains and go on about clearing the snow. Forget all the worrying about where to put snow, drifting, yada yada.
Plow it and be done with it especially when the blade will cost you 2000 and the blower 5000. Angle the blade and take a swath to the right on the way down, and on the left on the way back, clear around the garage and parking and you're done.
Plus the plow is more versatile, won't clog, or toss gravel fifty feet to wherever.
You're going to need a blade anyhow because that blower cant get close to the garage or any other tight spots either.
No offense but guys like blowers that big because when they are working they look cool, and you're the baddest blower man in town. But at the end of the day a plow blade will last longer, be cheaper, and more efficient, and useful.
