I don't have one long drive way, one about 150' plus my neighbors, another 150', both blacktop, both about 20' wide and both pretty level for the most part. Also, have a gravel drive to my barn, another 150' or so. My little Yanmar 2210 seems to do a better job pulling the snow than it does pushing it with the rear blade. For some reason, I have a lot more traction if I'm pulling the snow. I think it might be because the weight of the snow actually pulls the rear wheels down giving more traction, not sure. It does kind of roll up around the back tires but doesn't seem to cause a problem. Some of it goes off the edges, but I pull a pretty good sized pile.
I'm in central Ohio, probably getting some of the stuff you will be getting later /forums/images/graemlins/smile.gif Just plowed about 4-5" of heavy, wet snow. I pulled it into piles at the ends of the driveway, then turned around and pushed the piles into the grass. Speed is definitely your friend when trying to push a big pile of heavy wet stuff. If I ease up to it, I will just sit there and spin on the blacktop or dig into the gravel. I have to pull up a bit and hit it with some speed to get it moving. Last time I plowed, I had the blade at an angle, but this time I left it straight. To be honest with this little bit of snow, I really didn't see a difference. Although having it straight made it easier to back up to a wall or car or something like that and pull the snow away.
I think my snow blower probably does just as good a job, but the tractor is a lot more fun! /forums/images/graemlins/grin.gif Have fun and be safe!!
