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. Advanced hydraulics speed up multi-functioning and cycle times and give you more lift capacity. The D Series runs cool and is designed to keep debris from collecting inside the machine. Tilting cab and other access points cut the time needed for daily maintenance and servicing.
