Antique steam tractors in operation at steam show in Ohio, U.S.A. Steam tractors are powered by burning a combustible material to produce steam in a boiler that drives the wheels. These tractors are using their pulleys to drive belts that can be used in threshing, milling, and pumping. Much of the work done by 19th century steam tractors was beltwork in addition to plowing and pulling. | |
