Blizzard 2011, Beloit, WI, USA, Craftsman PGT 9500 (Simplicity Prestige), 42" 2-stage Snow Thrower attachment, 200 lbs rear carrier weights, 100 lbs rear wheel weights, rear wheel chains; no problems going uphill into deep snow over ice. After making this video, I noticed that I didn't have the throttle turned all the way up. I set it up to operating speed and the next driveway went even faster. I cleared 7 driveways and made a path down 2 blocks of road to free 3 stuck cars in 6 hours on 1 tank of gas.
