Fordson Snow Devil

(YouTube link)

This snow vehicle is an example of a screw-propelled vehicle.

In the 1920s the Armstead Snow Motor was developed. When this was used to convert a Fordson tractor into a screw-propelled vehicle with a single pair of cylinders, the combination became known as the Fordson Snow Devil. A film was made to show the capabilities of the vehicle as well as a Chevrolet car fitted with an Armstead Snow Motor.[6] The film clearly shows that the vehicle copes well in snow. Steering was effected by having each cylinder receive power from a separate clutch which, depending on the position of the steering gear, engages and disengages; this results in a vehicle that is relatively maneuverable. The promotional film shows the Armstead snow motor hauling 20 tons of logs.

Don't be goofy dilligaf69.
- Do you have any idea how much of the country uses 'foot' that way? It's a common dialect feature.
- Also, this is a film from the 1920's.
