Challenger Tractor

The Challenger Tractor was the world's first rubber tracked agriculture tractor, created by Caterpillar Inc. in 1986. The original model was a Challenger 65 featuring the Mobile-Trac System (MTS) consisting of rubber tracks and a suspension system. The MTS combined the flotation and traction of steel tracks with the versatility of rubber tires. The use of tracks gave the machines increased tractive performance compared to traditional four wheel drive tractors equipped with tires. The Challenger 65 began as a 270 gross HP machine used primarily for heavy tillage.
