Until I purchased my Kubota, I used a 48" single-stage frame-mount blower on my <ack> Murray 52" 5-speed "garden tractor" with a 25hp (I believe) Briggs motor. The drive I used it on was concrete, about 125' long and 12.5' wide. The biggest storm it saw was a 14" dumping of wet stuff. I had no complaints - 1-2mph throwing 14" of wet snow 15-20' sure beat shoveling. Tire chains were an absolute necessity as this was a 2wd setup. The drive sloped down and then up, perhaps 10' rise in a 50' run. The biggest issue with the whole setup was the hour and a half or so changeover required each season, as the mowing deck had to come off. This method sure beat a walk-behind dedicated thrower any day. Faster, more powerful, easier. What more could you ask for? Oh yeah, a snow blade on a Kubota <grin> (but that can't do sidewalks...). I should add that clearing 3-4" of snow could be done at almost full speed without bogging the motor. It was a cool setup that I'd recommend to anybody. The frame blower was purchased at Home Depot on clearance for about $500. My setup also included weights from Sears at each rear wheel - 50# each I think. I never tried clearing without them, so can't say what difference they made. I weigh in at 220, so that couldn't hurt either. Slipping chains can damage drives, so I always took it easy when things got super slick. If you had a gravel drive, I'd consider the v-bar chains.
