Operator Environment

Implement and Steering Controls

Machine direction, forward/reverse shifting and gear selection are all combined into a single tiller control located on the left armrest.
Standard Electro-hydraulic controls are designed for low effort. Operators have precise control of the blade and rear attachments, as well as the functions of a 6-way VPAT blade.

Power and Performance

Engine A Cat C7.1 ACERT engine gives you the power and reliability you need. Improved fuel economy over the previous model and efficient use of Diesel Exhaust Fluid (DEF) gives you excellent overall fluid efficiency.

Equipped for the Job

Undercarriage Elevated sprocket helps protect major components from harsh impacts and provides a modular design for convenient service.

Cat Connect Technologies

LINK Technologies LINK technologies provide wireless capability to machines enabling two-way transfer of information collected by on-board sensors, control modules, and other Cat Connect technologies using off-board apps, such as our VisionLink® software.

Emissions Technology

Aftertreatment Technologies To meet the additional 80 percent reduction in NOx emissions required by Tier 4 Final/Stage IV emission standards, Caterpillar engineers added Selective Catalytic Reduction (SCR) to the already proven aftertreatment solution.

Serviceability and Customer Support

Ease of Service The D6N is designed to help you get routine service done quickly and efficiently so you can get to work.

Special Arrangements

D6N WH Waste Handler

Specialized guarding, striker bars and seals help protect the machine from impact and airborne debris.
Bottom and final drive guarding help prevent debris from wrapping around or damaging vital components.
The cooling system is designed for high debris environments, with easy access for cleanout.
