This book covers the tractor models that have stood out, from the early twentieth century to the present day, either because of their innovative design and engineering features or because they set new standards in reliability and popularity. Beginning with the background to the development of the first tractor, Jonathan Whitlam takes us on a fascinating journey through a variety of tractor types, both large and small, and their stand-out features. This includes the Fordson F, the first mass produced tractor which set the pattern for future tractor design, the Field Marshall, which introduced diesel engines for tractors, the Ferguson TE20 with its novel three-point linkage, the Massey Ferguson 35 and later 135, which stand out for sheer popularity, and the John Deere 3640, with its powerful six-cylinder engine and advanced cab. The book also describes the computerised systems featured in many of the latest tractors. Accompanied by superb colour photography of all the tractors, this book has something for every tractor and agricultural machinery enthusiast.
