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.
  • 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

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.

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.

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.

Equipped for the Job

Undercarriage

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

Blades

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.

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.

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.

Product Link™/VisionLink

Product Link takes the guesswork out of equipment management. Track location, hours, fuel usage, productivity, idle time, and diagnostic codes through the online VisionLink interface. Manage your fleet in real time so you can maximize efficiency, improve productivity, and lower operating costs.

GRADE for Dozers

Cat Connect GRADE technologies help you hit target grade faster and more accurately. Finish jobs in fewer passes, and with less operator effort, saving you time and helping you increase profit.

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.

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.

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.
  •     

  • Specialized air handling features help deliver cleaner air to the machine.
  •     

  • Landfill blades and center-hole track shoes help you optimize your waste handler for the job.
D6N Forestry Arrangement
  • Optional sweeps help protect the cab, top and sides of the machine.
  • Screens give added impact protection to cab windows (ISO 8084).
  • Additional guarding helps protect the underside of the machine from stumps and other heavy debris.
  • The cooling system is designed for high debris environments, with easy access for cleanout.
