PRODUCT DESCRIPTION

Building on Caterpillar's 40+ years' experience designing and manufacturing skidders, the Cat® D Series Wheel Skidder delivers more productivity at lower operating cost. Get more wood to the landing faster in a stable machine with a roomy, comfortable environment for the operator.
