In 2001 Caterpillar sold their agricultural equipment business to Agco. A big part of that was the Challenger line of belted or rubber tracked tractors.
We cover Caterpillar items older than 2001 that are agricultural. We cover newer items that bear the Challenger brand. Early history of Caterpillar is welcome. Equipment that is sold as Challenger and under the other Agco brands such as Agco and Massey Ferguson is welcome. Trade publication links are great. Commentary about the development of rubber track technology is of real interest as is comparisons of other companies that have adopted rubber track technology. Manufacturing facilities that produce Challenger products and their specific products made there are certainly on topic.
