In 1769 James Watt took out a patent on a steam engine making use of a separate condenser. James Watt's improved steam engine transformed previously designed steam engines, which had hardly changed for fifty years, into a source of power that transformed the world of work, and was the key innovation that brought forth the Industrial Revolution. Farmers started buying self-propelled steam engines in the late 1870's in considerable numbers. In 1890 approximately 3000 steam tractors and 2661 steam threshers were built. In 1894 several plow manufacturers advertised multiple-bottom steam tractor plows or gangs. By 1900 more than 30 firms were manufacturing some 5,000 large steam-traction engines a year. These tractors were greatly improved over earlier models.Traction engines were cumbersome and ill-suited to crossing soft or heavy ground so their agricultural use was usually either "in the belt" – powering farm machinery by means of a continuous leather belt driven by the flywheel – or in pairs, dragging an implement on a cable from one side of a field to another. However, where soil conditions permitted, direct hauling of implements ("off the drawbar") was preferred – in the U.S., this led to the divergent development of the steam tractorA.B. Wilson came along in 1928 with what he thought was a better Idea. He invented a smaller tractor with rubber wheels and a fast forward and reverse. He patented his invention and received patent # Production started in Melvin – only one was produced. The market went to gasoline engines and he was just too late.This model was purchased at a Smithsonian Surplus Item Auction by Butterfield and Butterfield in San Francisco in 1991.
