The developmental history of the tractors built by the dominant agricultural manufacturer of the early 20th Century, International Harvester, is dramatically told in The Farmall Dynasty. The book traces the evolution of the Farmall tractor from the early Titans and Moguls through to modern times. The book includes well-researched accounts of the development of the original Farmall, the Letter Series, 4100, Cub, and other legendary IHC tractors, with first-hand accounts from factory engineers describing the challenges they faced. This book is an updated revision of the text from the rare and now out-of-print International Harvester Photographic History (ISBN 0-7603-0130-1).
