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.
