I live about 4 miles out of town in the country, and 2 years ago we had a 14" snow. I took my old tractor (TC29D) into town and cleared driveways that day, from morning until a couple hours after dark. I cleared a BUNCH of driveways. Maybe 100 or close to it. My tractor had R4's and I did not have a single problem. I guess it could depend on the consistency of the snow, wetness, etc,... but in my experience, the tractor did excellent. I even pulled a couple cars out of ditches. I love R4's.
