One of the world's best-loved farm tractors, the Ferguson T20 was built in huge numbers across the world. Harry Ferguson was a remarkable inventor and a man of vision and he is best remembered for the small unobtrusive grey tractor that bears his name. Launched in the 1940s, it rendered its competitors obsolete and provided farmers worldwide with a tool that could meet almost all their requirements. This book charts its development and evolution, including the US- and French-built models, special purpose versions and industrial types. Over 500,000 Ferguson T2s were sold all over the world. It replaced the horse on many post-war farms. This book, by a renowned expert of the marque, includes many unpublished facts and photographs. It contains an extensive study of the extraordinary range of implements available, with additional information on tractor options and accessories.
