Man adjusts belt on antique steam tractor at steam show in Ohio, U.S.A. Steam tractors used belts driven by a pulley for use in threshing, milling and pumping. Much of the work done by 19th century steam tractors was beltwork in addition to plowing and pulling. Steam tractors are powered by burning a combustible material to produce steam in a boiler that drives the wheels. | |
