The story of the four-wheel-drive tractors built by Steiger and Case IH are told in dramatic fashion in this authoritative guide. Starting with the development of barn-built tractors by the Steiger family, the book traces the evolution and design of some of the most powerful and capable tractors of the twentieth century. With fresh detail on the Steigers as well as the Steiger-built IH tractors, the book offers prototype drawings of several models-including the complete story of the Magnum 2+2 - as well as inside stories and backroom drama that is a must for any enthusiast for farm history or tractors. Learn the complete story of Steiger tractors, which were originally designed and built in the barn of John, Douglass, and Maurice Steiger located near Red Lake Falls, Minnesota. Containing interviews with more than 100 of the people who built Steiger from its humble origin to a world leader, the book traces the evolution of the lime green Steigers in engrossing detail. In addition, the book tells the story of how each of these significant players in the industry combined under one banner and-together-created one of the current industry-leading technologies, the Quadtrac. The modern evolution of the Steigers and the introduction of the STX Series (and more) also receive in-depth coverage.
