CHIEFTAIN D

The Chieftain D is a large, four tracked vehicle designed to move heavy payloads in mud, muskeg, swamp, and snow conditions. The high deck and sealed undercarriage components provide excellent fording ability combined with high approach and departure angles. The independent crankarm suspension and flexible track provide constant ground contact and absorb shock loads.
