Title: Steam Powered Traction Engine, 19th Century
Caption: A traction engine is a self-propelled steam engine used to move heavy loads on roads, plough ground or to provide power at a chosen location. Traction engines tend to be large, robust and powerful, but heavy, slow, and difficult to manoeuvre. Nevertheless, they revolutionized agriculture and road haulage at a time when the only alternative prime mover was the draught horse. They became popular in industrialized countries from around 1850, when the first self-propelled portable steam engines for agricultural use were developed. Production continued well into the early part of the 20th century. This image has been color enhanced.
