In this fabulous, fact-packed and intensely visual encyclopedia, John Carroll charts the extraordinary history of the machines and their manufacturers from the early days of the J.I.Case Threshing Machine Company and its experimental gasoline tractor of 1892, to the JCB Fastrac, one of the numerous state-of-the-art machines now on the market. Each piece of machinery is illustrated with fascinating archive material or full-color photography, and the informative text includes specification boxes and a detailed mechanical profile.
