Tractors of the World

Tractors come in all different shapes and sizes, and Tractors of the World covers the field from the early steam-driven monsters to the traditional two large, two small wheel configuration; the Row Crop models with two small front wheels placed close together and two large rear wheels; and finally to the ultimate modern, four-wheel-drive, multigeared, mega-beasts with GPS devices and onboard computers. This is a colorful pictorial history of the tractor that depicts the days of primitive steam-powered traction engines, through to the sleek, sophisticated powerhouses that perform as the main workhorse of today's farming industry.
