The production of tractors began about the beginning of the 20th Century with the development of the internal combustion engine, and following on from the beginning of the evolution of the automobile. There were other farm engines in use earlier, notably the plough and crude harvesters, but the purist would say that gas traction engines for farm tractors were made in large scale only in about 1901, giving rise to one of the most incredible enthusiast interests enjoyed: the history of international farm tractors. All the great names leap from the pages of this essential reference book - John Deere, Caterpillar, Oliver, Ferguson, Massey, International Harvester, Allis-Chalmers, Ford, Orphans, and many more - as the author presents fact-filled essays on the major tractor producers and their fabulous products.
