The Tractor Factor [PDF ebook] 
The World’s Rarest Classic Farm Tractors

With tractor historian Robert N. Pripps, take a close look at some of the most collectible vintage tractors from the United States, the UK, Germany, Holland, France, and other countries.

Vintage farm tractors are revered throughout the world as the source of mechanical labor, allowing the revolution of farming to take place in the twentieth century. Some of the most interesting tractors are also the rarest, since they were produced in very small quantities. These include one-of-a-kind modified models; very, very old machines; and models produced by one of the many companies that made tractors for only a short time.

The Tractor Factor is a richly illustrated book that reveals what makes a tractor collectible, showcases the rarest models, gives a history of the marque, and details specific finds. Robert N. Pripps, a leading tractor historian, covers models from the United States, the UK, Germany, Holland, France, and other countries. Pripps’ expertise, paired with the stunning photography of Ralph W. Sanders and Andrew Morland, makes The Tractor Factor a book no fan of these paradigm-changing machines will want to miss!
