That thing or something similar has been around for several years - thanlfully I never bought one. I can see that it might work ok on the first snow fall of the season, if the accumulation is not more than about 10 in. But what happens with subsequent storms after the snow banks have built to 3 or 4 feet high from previous storms? How can this device pitch the snow up & over?
After clearing my current driveway for the past 40 years, initially with a shovel (three storms a week apart), then with a 7 hp blower; I'll definately stay with a snarling, noisy, gas guzzling machine. And when the snow is wet and heavy I'll be wishing for 10 or 15 hp!
It is a good conversation piece!
