Allis-Chalmers, Model IB Tractor with 16 HP Engine, Equipped with a Baker "V" Type Sidewalk Snow Plow. This view shows the Tractor Plow unit proceeding north on Hungerford Terrace after an 8 inch fall of snow combined with rain, which made the plowing very heavy and difficult for horse drawn equipment, but this unit did not experience any difficulties. Note: For a more detailed description see the original print.
