Workers with Best Manufacturing Company Steam Tractor and Combine Harvester, circa 1896

Some agricultural steam engines had to be hauled from farm to farm by teams of horses. Some - like the one pictured here - moved under their own power. This self-propelled traction engine hauls a combine harvester. The colossal duo aided farmers tremendously at harvest time--simultaneously cutting the crop, loosening the grain, and separating the grain from the chaff.
