Operator Environment

Operator Environment

Comfort and productivity

Roomier cab with a wider entry offers added comforts like a heated/ventilated seat option, manually adjustable armrests, larger cup holder and auxiliary power port. Smoother shifting and a quieter engine add to overall operator comfort. Modified cab seals and ducts help improve heating and air conditioning performance, and a redesigned cab/fresh air filter helps keep the cab cleaner. A color LCD display shows vital operating information, as well as Slope Indicate real-time machine mainfall and cross slope. A grade control display can be integrated right into the dash so data is available at a glance.

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.
  • A variable throttle control dial lets you use preset engine speeds, or select Enhanced Auto Shift modes.
  • Bi-directional shift allows you to automatically select the desired forward/reverse speeds or a custom setting.
  • Selectable Electro-Hydraulic Maps set the implement response levels – fine, medium, coarse – to match operator preferences and tailor the machine to individual applications.
  • Implement Lock-Out prevents inadvertent operation of hydraulic attachments.

Power and Performance

Power and Performance

Designed to get the job done


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.

Cooling System

A single plane design makes cleanout easier, and durable aluminum bar plate construction gives you superior heat transfer and corrosion resistance. A swing-out door provides easy access for cleanout.

In cooler conditions, an improved variable speed demand fan slows down to conserve power, save fuel and reduce sound levels.

An optional manually reversing fan is available for high debris conditions, and an optional sand blast grid can help protect the radiator from abrasive materials and debris.

Lock-Up Clutch

Transmission controls will automatically select the drive mode best suited to your application, providing increased productivity and efficiency.* The new transmission with a lock-up clutch torque converter gives you the performance of direct drive with the ease of operation of power shift.

Enhanced Auto Shift

Standard Enhanced Auto Shift helps you save fuel by automatically upshifting/downshifting to maintain the most efficient gear based on load. Three different settings – 3-speed, 6-speed and fine adjustment mode – allow you to optimize tractor performance to match material and job site conditions.

Differential Steering

Differential Steering maintains full power to both tracks for best-in-class turning, even with a full blade load. When one track speeds up, the other slows down an equal amount, so you have better maneuverability and faster cycle times. Load capacity, power and speed control are also better when working in soft conditions.

Load Sensing Hydraulics

Field-proven system senses the load and continuously adjusts hydraulic power to your blade to maximize efficiency.

*Compared to the previous D6N model.

Equipped for the Job

Equipped for the Job

Optimize your machine


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

Choose Heavy Duty undercarriage for aggressive applications like land clearing, side-slopes or rocky terrain. Or, choose SystemOne™ undercarriage that is designed to work and wear as a system for longer life and lower costs in abrasive or low/moderate impact applications. A broad choice of track shoe designs and widths help you further optimize your machine for performance and longer life.


Semi-Universal and Straight blades are designed with a strong box section to stand up to the most severe applications. Heavy moldboard construction, hardened bolt-on cutting edges and end bits add strength and durability.

The Variable Pitch Angle Tilt (VPAT) blade allows you to hydraulically adjust lift, angle and tilt for precise results. The VPAT blade is wider to take on a variety of applications so you can use your D6N for spreading material, finish grading, side casting, V-ditching and backfilling. An optional folding VPAT blade is available to reduce overall machine width to more easily meet transport requirements.

Rear Implements

To help you match your D6N to the task at hand, you can outfit your D6N with a multi-shank ripper, winch or drawbar.

Ask your Cat dealer for available options to help you optimize your machine for the work you do.

Emissions Technology

Emissions Technology

Proven, integrated solutions

Emissions reduction technology on the D6N is designed to be transparent, with no action required from the operator. Low temperature regeneration runs automatically in the background while you work.

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.

Diesel Exhaust Fluid

Selective Catalytic Reduction utilizes Diesel Exhaust Fluid (DEF), which can be conveniently refilled when you refuel. The DEF fill nozzle is located next to the fuel tank, with easy access via a rear step. A tone will sound (with key on), when the tank is nearly full and a gauge on the dash shows your fluid level. The system is designed to use one tank of DEF for each tank of fuel (1:1 DEF fill ratio). The D6N typically has used DEF at a rate of 2-3 percent of fuel consumption.

When the machine is turned off, a pump will automatically purge the DEF lines to help prevent freezing. A symbol on the dash and a light/symbol on the Ground Level Service Center indicate when the purge is complete and that it is safe to turn off the electrical disconnect. If the engine/aftertreatment temperatures are high, a Delayed Engine Shutdown will activate automatically to cool the machine and then purge the lines. For complete aftertreatment information, please refer to your machine’s Operation and Maintenance Manual.



Designed with protection in mind

  • Optional rear vision camera enhances visibility behind the machine and is integrated into dash display.*
  • Added grab handles on the door help you get on and off the tractor with greater ease.
  • Well-appointed cab with good visibility helps operators stay focused and aware.
  • A standard Operator Presence detection system allows the machine to idle when the operator is not seated, but locks out the power train and front and rear implements to avoid unintentional movement.
  • New seat belt indicator enhances safety by reminding the operator to buckle up with a light/alarm. Once the machine is in gear, a fault code will register through Product Link if the operator fails to fasten the seat belt.

*Please consult your Cat dealer for availability.



Thinking generations ahead

  • Fuel efficiency is improved by 10-15% compared to the previous model.
  • Fuel savings reduces CO2 production by an average of approximately 2.6 metric tonnes per year.
  • Meets Tier 4 Final/Stage IV emission standards.
  • Typical Diesel Exhaust Fluid (DEF) use of 2-3 percent of fuel consumption gives you excellent overall fluid efficiency.
  • Major components are built to be rebuilt, eliminating waste and saving you money by giving your dozer a second – and even third – life.

Serviceability and Customer Support
