It all depends on your snow load and how wet the snow is. On Friday we got about ten inches of snow, the windrow I was blowing was almost to the top of the blower. I was loading a tri-axle dump about every 50 yards and at a snails pace. Yesterday we got about four inches and tonight I was traveling at a brisk walking speed filling a truck over about 300 yards. In both cases the temps were well below freezing and the snow was dry.
I've worked in some real wet snow where it will barely make it over the side of the truck it's so heavy. This stuff is tough to work in. Like I mentioned before, you'll need to listen to the pitch of the impeller, you'll hear it start to slow before the chute clogs, back out of it immediately otherwise it will clog. With practice you'll learn to recognize the sound it makes just before clogging, you'll have about 1 second to adjust before it clogs. When I first started using the blower, I'd clog it a couple times a night. Now that I've run it a few years I can't recall the last time I clogged it. It gets better with practice
