All of us have heard of the cola wars, the tennis shoe wars, and certainly the PC wars. But the tractor wars?

Neil Dahlstrom is a historian and archivist for John Deere, and he's the author of Tractor Wars, a historical narrative of the race to be the top manufacturer of power farming at the turn of the twentieth century. Will it be International Harvester, Ford, or the much smaller player, John Deere?

Neil's book is a story of what-ifs, including pricing wars, business rollups, marketing insights, and bold moves by Henry Ford.
