When John Deere entered the multi-cylinder fray, it did so with the most advanced, groundbreaking machines ever built – the New Generation tractors. Today John Deere stands alone as the last of the great American independent ag manufacturers. Yet it is still going strong, still setting trends, and still building the icons of the future. The author traveled more than 12,000 miles across America’s heartland to document and photograph this "inside story" of John Deere’s history. Along with exquisite photos of rare tractors, he came upon decades of personal diaries by Deere’s chief engineers, giving a rare glimpse into their passion to make life easier for farmers.
