I got one with the 8hp Briggs 2 years ago. Pretty much the same except for the engine. I think yours might have a anti-jam slip clutch. An 11hp was $400 more at the time. It usually does O.K. except with heavy snow... at those times I wish I had the 11hp.
It seems like a real good blower so far. It's got enough weight to power through hard drifts. I put a fabric disk in the chute pitch control to get better control since I have passes which require me to flip from side to side without changing the pitch much.
I think you'll like it.
