1912 Knox-Martin Tractor

In the early 20th century, businesses and city governments owned many specialized, horse-drawn freight and service wagons. When owners decided to replace their horses with motor vehicles, tractors were more appealing than trucks because the wagons could be kept and used as trailers. The Knox Automobile Company manufactured tractors with a fifth wheel hitch that was adapted to wagons. And unlike a truck, a tractor could be detached from the wagon and haul more goods while the first wagon was being loaded or unloaded. The Knox-Martin’s single front wheel swung easily and turned the vehicle in a tight radius, accommodating these maneuvers.
