Buy aftermarket replacement rubber tracks for your Caterpillar Challenger agriculture tractors online with free shipping. Challenger tracks are offered in eighteen-inch, thirty, and thirty-six-inch wide options. Our tracks come with heavy-duty aggressive directional tread pattern bars made in durable general-use rubber compounds. We offer tracks for the Challenger 35, 45, 55, 65, 75, and 95 series models. The Challenger brand was taken over by AGCO many years ago but there are still many Challenger 35-95 models in operation today. Our popular eighteen-inch wide Cat 35, 45, and 55 series tracks allow for flexibility with narrow rows for smaller farms. The Challenger 65 series typically utilizes thirty to thirty-six-inch wide rubber tracks for larger farms with wider row crops.
