First there were horses and oxen, then the self-propelled steam traction engine and finally the tractor as we know it today. But farmers can be a headstrong bunch, not always quick to replace great-granddad’s time-tested systems with newfangled contraptions. Michael Williams, expert in agricultural machinery, takes you on a 224-page global tractor tour that starts back in the 19th century. Ever heard of John Deere’s Waterloo Boy? Henry Ford’s Model F? How about International Harvester’s Farmall? You’ll be a tractor trivia champ by book’s end!
