The Snogo Snow Blower was used on the Trail Ridge Road in Rocky Mountain National Park, USA. Manufactured in 1932 by the Klauer Engineering Company of Dubuque, Iowa, the plow was actually a snowblower and featured advanced features such as an enclosed cab, four wheel drive and roll-up windows. It was used in the park until 1952.
The Blower used a Climax Blue Streak six-cylinder gasoline engine (6x7=1188cuin), developing 175 horsepower at 1200 RPM. Through the use of an eight-speed gearbox, speed could be varied from 1/4 mile/hr up to a maximum of 25 mph, when not moving snow. It was claimed to be capable of throwing snow 100 feet to the side.
