A demo film of the Armstead Snow Motors Company concept snow vehicle - powered by a Fordson tractor and a Chevrolet automobile.
In January 1926, Time magazine reported:
“Having used the motor car for almost every other conceivable purpose,
leading Detroit automobile makers have now organized a company entitled
"Snow Motors Inc.," to put out a machine which will negotiate the
deepest snowdrifts at six to eight miles an hour.
The new car will consist of a Ford tractor power-plant mounted on two
revolving cylinders instead of wheels—something on the order of a steam
roller.
