Wayne,
I move most of my snow with a 106 with a homemade 48" blade. I used to just put about 150# on the back and chains on the tires. I used to run 8.5's like your 108 should have. Last year I ran some 10.5's on it but had to put more weight on it to get the same traction. I can move a lot of snow in southern Wisconsin with it. I have some pictures of it sitting in front of a pile of snow almost 5' tall. I also have some pictures of it pushing snow up 40* hills without too much trouble. As has been said, do not underestimate what these units can do.
