Antique steam tractor in operation at steam show in Ohio, U.S.A. This tractor is using its pulley to drive a belt 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. Steam tractors are powered by burning a combustible material to produce steam in a boiler that drives the wheels. | |
