Scruffy,
Here are some photos of the Zamboni. It was made in 1967 and is # 852. After 50 years of production they have only made about 6000 units. A new one sells for about $65K. They are built like tanks, and weight about 8500 lbs. when filled with water. (holds 180 gal.) As for carting the tools, its not too bad. After a while you learn what will need to stay in the lower part and what you need up top. There is a set of stairs inside so its not that big of a deal. By the way the top floor is 5-7" thick and weighs 27K lbs.
Bill,
I didn't use the tractor to dig out the basement for the shop as I needed a backhoe for the footer on the backside. So I just hired it out for $300.00
