The new D6K2 dozer is smarter and more efficient than ever. It comes equipped with standard Grade technologies like Slope Assist to make it easier for even less experienced operators to get more quality work done in less time. But intelligence is only part of the package – Eco Modes and a new power train deliver up to 17 percent more fuel efficiency, while providing superior maneuverability, faster steering response and greater capability to utilize full blade loads. This dozer also retains its optimal balance and undercarriage design for outstanding performance in finish grading applications. The D6K2 meets Tier 4 Final/Stage IV/Korea Tier 4 emission standards.
