One of the more curious attempts at building an over-the-snow vehicle back in the 1920’s comes from the Armstead Snow Motors Company of Michigan. Powered by a Fordson tractor (and a Chevy automobile), their snow vehicles utilized a dual auger-drum propulsion system. Granted, these were not the small single passenger machines built by the likes of Carl Eliason, Edgar Heteen or Joseph Armand Bombardier, but they are yet another chapter in the history of man’s desire to conquer the winter’s snow.
The vehicles removed the wheels and axles, which could be re-installed for summer use, and installed a set of two auger drums. Flotation was quite impressive, as was their overall capabilities (the tractor version could pull up to twenty tons of logs).
This link will take you to a short eleven minute video (with no audio, it was 1924) of the machines in action. Considering it was 85-86 years ago, you can appreciate the capability of their efforts.
