Overview

The latest in the line of Cat D6N dozers combines well-known versatility with a range of technology features to give you more job site productivity than ever before. A new transmission with lock-up clutch torque converter delivers ease of operation, increased net power, plus a 10-15 percent improvement in fuel efficiency. The D6N has the weight and horsepower you want for dozing applications and the balance and stability you need for finish grading – all in one easy-to-transport machine. The D6N meets U.S. EPA Tier 4 Final/EU Stage IV/Korea Tier 4 emission standards.
