Our storms come up from the southern USA. Sometimes wet, often with a lot of drifting back in.
Inverted blower is 90". The rear blade is my add on. Using a garage door remote, open the door, back up and lower the rear blade just inside the garage and drive forward. This creates a small pile away from the door so you back up a little so the blower catches it.
No shoveling like most other designs leave for you.
I can drive in high range second gear at 4.5 mph blowing. Sometimes there is not enough power and I have to slow down.
