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.
All non road Tier 4 Interim and Final, Stage IIIB and IV, and Korea Tier 4 diesel engines are required to use only Ultra Low Sulfur Diesel (ULSD) fuels containing 15 ppm EPA/10 ppm EU (mg/kg) sulfur or less. Biodiesel blends up to B20 (20% blend by volume
Diesel Exhaust Fluid (DEF) used in Cat Selective Catalytic Reduction (SCR) systems must meet the requirements outlined in the International Organization for Standardization (ISO) standard 22241.
Engine ratings at 2,200 rpm
Net power advertised is the power available at the engine flywheel when the engine is equipped with the air cleaner, alternator, A/C compressor at full load and cooling fan at maximum speed.
No engine derating required up to 3000 m (9,840 ft) altitude; beyond 3000 m (9,840 ft) automatic derating occurs.
