Mount a pair of screw-designed and hollow pontoons on either side of a Fordson tractor and you might be able to travel pretty much anywhere, over snow, ice, even over water.
That was the idea behind the Fordson snowmobile concept vehicles — aka the Snow-Motor — created in the mid-to-late 1920s. What is believed to be the only one still operational was restored and displayed by the Fountainhead Antique Auto Museum in Alaska.
Top speed is reported to be 8 mph but the device can tow 20 tons of logs out of the forest.
