Four-wheel drive
Four-wheel drive demand increased significantly, with Versatile becoming one of the leaders in four-wheel-drive development and production. By the late 1970s, the Versatile lineup included tractors ranging from 220 to 330 horsepower. With the 1980s came an expanded line of four-wheel-drive tractors that stretched to 470 horsepower in the Versatile 1150. They entered the race to build the largest tractor in the world with "Big Roy", named after one of the founders, in 1977. Roy produced 600 HP on the draw bar.
