Before John Deere, Ford, and International Harvester became icons of American business, they were competitors in a forgotten battle for the farm. From 1908-1928, against the backdrop of a world war and economic depression, these brands were engaged in a race to introduce the tractor and revolutionize farming. By the turn of the twentieth century, four million people had left rural America and moved to cities, leaving the nation's farms shorthanded for the work of plowing, planting, cultivating, harvesting, and threshing. That's why the introduction of the tractor is an innovation story as essential as man's landing on the moon or the advent of the internet -- after all, with the tractor, a shrinking farm population could still feed a growing world. But getting the tractor from the boardroom to the drafting table, then from factory and the farm, was a technological and competitive battle that until now, has never been fully told. A researcher, historian, and writer, Neil Dahlstrom has spent decades in the corporate archives at John Deere. In Tractor Wars, Dahlstrom offers an insider's view of a story that entwines a myriad of brands and characters, stakes and plots: the Reverend Daniel Hartsough, a pastor turned tractor designer; Alexander Legge, the eventual president of International Harvester, a former cowboy who took on Henry Ford; William Butterworth and the oft-at-odds leadership team at John Deere that partnered with the enigmatic Ford but planned for his ultimate failure. With all the bitterness and drama of the race between Ford, Dodge, and General Motors, Tractor Wars is the untold story of industry stalwarts and disruptors, inventors, and administrators racing to invent modern agriculture -- a power farming revolution that would usher in a whole new world.
