So, we recently moved into a new house with a driveway that is probably 100 or so yards long. It gradually slopes up to the house, with a couple 10 yard points that are a bit steeper than the rest. I'm guessing the steepness of the slope is probably fundamental to answering this question - about all I can say is that it's relatively modest but you know its there. Maybe 20-30 foot worth of rise over the length? I decided that I wasn't going to think about attempting this with my old 5 hp 22 inch blower. It's a solid, reliable beast but a bit underkill in this situation. So, I found a 38 inch blower that mounts to the front of my garden tractor. My tractor is an 18hp Deere 116 w/turf tires. Probably 500 lbs. I have two weights for the back of it that are probably 90 lbs total, plus there is me at about 245. I'm curious if I have a snowball's chance of blowing this driveway without buying chains? My concern with the chains is that it is a relatively new asphault driveway, and I don't want to tear it up. I've heard horror stories about people digging in when spinning, and marking stuff up. Or, should I buy a pair just in case? We don't get much ice, just snow.
