ALLIS-CHALMERS, MODEL 1B TRACTOR WITH 16 HP ENGINE EQUIPPED WITH A BAKER "V" TYPE SIDEWALK SNOW PLOW NO. 281420-223V-107. This view shows the No.1 Tractor plow unit plowing snow in Battery Park. Notice the depth of the snowfall which is approximately eight inches. This equipment did not experience any difficulty in plowing this depth, although as you will note in the picture the snow had become frozen and difficult to plow with ordinary horse-drawn plows. This unit removed the snow from three routes formerly requiring the services of three horse-drawn units, the time required being approximately five to six hours depending upon the weather conditions, the gas consumption being approximately four to five gallons per trip. The total distance covered by the entire trip is approximately twenty miles. The specifications of this unit can be found on the back of the original photograph. 1938-1940
