"This rollicking ride into machine history follows the innovators, entrepreneurs, and hucksters who transformed our world with farm machines of all colors. Starting with the turn-of-the-century visionaries who saw that four wheels and a motor could replace for the horse, the book moves swiftly through key early developments to cover the power farming movement of the latter part of the 20th century- a time when major manufacturers lagged and independent builders and farmers began creating their own machines with a pencil drawing and a welder. The book includes key moments of tractor history."--book jacket
