Caterpillar is a global manufacturer of industrial equipment and was a pioneer in tracked machinery. Caterpillar tractors have been used for farming since their beginning, but the company's focus shifted to construction as rubber tire tractors dominated the agricultural market. Caterpillar re-entered the farm market with the Challenger line of rubber-tracked crawlers in 1987. The Challenger line was sold to AGCO in 2002.
