In the mid-1920s, a curious conversion kit became available.
From what I could find, Snow-Motors Inc., based out of Detroit, Mich., offered a kit that replaced the wheels and axles to a number of conveyances with “two revolving cylinders instead of wheels — something on the order of a steam roller,” as Time reported in January 1926.
The snow motor conversion enabled someone to travel from 6 to 8 mph across snow and ice with ease. “The machine has already proved its usefulness in deep snow previously unnavigable,” Time continued. “One such machine has done the work which formerly required three teams.”
In the promotional film below, courtesy of YouTuber LETHLSS, the Snow-Motors kit is demonstrated with a Fordson tractor and a Chevrolet automobile. Thanks to Bob Kuhns, of Arlington, Kan., who brought this intriguing contraption to our attention. He came across the video posted on the TreasureNet forum; that version of the film suggests it resides in the “Archives of Michigan.”
