Caterpillar Challenger — Cat's rubber-track tractor, now built by AGCO
The Challenger line covers 15 models in the database from 149 to 310 kW, consistently with six-cylinder engines — a power class that clearly points to large farm tractors rather than construction machines: the Challenger was Caterpillar's entry into rubber-tracked agricultural tractors.

Cat launched the line in 1986 with the Challenger 65, fitted with its own Mobile-Trac System — sprung rubber tracks combining the flotation and pulling power of steel tracks with tyre-like road manners. In 2002 Caterpillar sold the entire Challenger tractor business to AGCO, licensing the name and livery — since then the line has continued under the Challenger brand at AGCO, while Caterpillar itself refocused on construction equipment.
Challenger tractors were, and still are, used mainly in large-scale row-crop farming, where the soil-friendliness of rubber tracks combined with high drawbar pull is the deciding factor.
For an older, originally Cat-built Challenger (pre-2002), the condition of the rubber track undercarriage and the suspension components matters most.
In short: reading "Caterpillar Challenger" historically means buying a farm tractor, not a construction machine — and depending on the build year, either an original Cat product or a later AGCO product under Cat licence.
