Hi Lloyd
Are you guys getting lots down there as well? I don't know about getting a bigger tractor, someone here said that a smaller tractor will do the same job ...just takes longer. I'm really amazed at what that little tractor will do. The only real way to deal with snow like this is a snowblower.
I found the best method was to push the snow as far as I could, back up, push the top of the pile a little further then scoop up the bottom and dump it over the top of the pile. Eventually I had to scoop up snow and dump it off to the side as the pile got too big. I really had fun learning what worked and didn't work. I only had to dig myself out at the begining. I've never used R4 tires so i can't compare but the farm tread worked great with no additional weight other than the box blade full of snow and ice.
The first pic is what I found fri morning when I got there, the next is my daughter and her husband where I finally called it quits for the day (beautiful dog ..eh), next is my cabin in its winter splendor and then a pic of the path I made going down the hill to my cabin.
