They were made by the Snowmobile Company in Ossipee, NH. They were sold to Ford Dealers who installed the snowmobile kit on Model T Fords. They cost about $400.00 about the same as the cost of the Model T. http://www.youtube.com/watch?v=-9CgOhj0HP0
I wonder what all tire sizes they work with?? It was kinda sad to see them rubbing on the front air dam under the bumper...... I had a buddy with a set of Mattracks for his hummer and they really do sound that way on the hard pack, LOL
I dunno but it looks like the same exact thing I was driving through in my 1990 Toyota on Saturday night. Theirs seems to sink in less though. My old pickup is THIRSTY churning through that crap too. It's a 3.0 V6 and in about 70-80 mile round trip it drank about 2/3 of a tank. I love looking in the rearview and seeing the divots from the differentials. (not to mention the tools in their "SUV-style" $60,000 minivans creeping along)
I would be interested to see what would happen if the 7000 pound truck ran across a snow drift that could not be seen, like across a ten feet deep ravine.
Would it stay on top of soft drifted snow.....or sink out of sight until spring?
