Engineered to excel on the most demanding work sites. The D6N combines power, rugged components and superior balance, for maximum performance in the toughest working conditions. It keeps material moving with the reliability and durability you expect from Caterpillar® machines. The D6N features advanced electro-hydraulic controls which have been designed and tuned to achieve maximum productivity and performance when equipped with AccuGrade GPS, ATS or Laser Grade Control Systems.
The Cat® C6.6 is a 6.6 liters (403 in3) displacement, six cylinder, inline configured engine equipped with a Caterpillar Common Rail fuel System. It uses ACERT Technology, a series of Caterpillar engineered innovations that provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions. It meets the U.S. EPA Tier 3, European Union Stage IIIA and Japan MOC Step 3 emissions standards.
Electric Fuel Priming Pump
The electric fuel priming pump provides quick, effortless fuel priming.
The direct injection electronic fuel system provides a controlled fuel delivery increase as the engine lugs back from rated speed. This results in increased horsepower below rated power. A combination of increased torque rise and maximum horsepower improves response, provides greater drawbar pull and faster dozing cycles.
Caterpillar’s Multi Velocity Program (MVP) allows operators to choose from five different speed ranges in both forward and reverse, increasing machine productivity, decreasing fuel consumption and significantly reducing operating costs.
Auto-shift allows the operator to select a forward and reverse speed combination for easy, efficient directional changes. The operator can select a combination of any forward and reverse speeds or use one of three factory settings. The factory auto-shift settings include: 1.5 forward/2.5 reverse, 2.5 forward/2.5 reverse, and 2.5 forward/1.5 reverse. Auto-kickdown allows the transmission to automatically downshift when significant load increases are detected, ensuring maximum dozing performance.
Elevated Final Drive
Isolates final drives from impact loads for extended power train life.
Protects sprocket teeth, bushings and final drives from debris, abrasive materials and moisture.
Provides long-lasting final drive performance and durability.
Designed for operator comfort, superior control and high productivity.
Designed for quiet, comfortable, productive operation all shift long. Large glass panels provide excellent visibility to the blade, sides and rear of the machine, for safe, effective operation in tight operating areas. Acoustic headliner material, and sound suppression foam panels ensure quiet machine operation, and automatic temperature control provides unmatched operator comfort.
Cat Comfort Series Air Suspension Seat
Cat Comfort Series Air Suspension Seat is fully adjustable for maximum operator comfort, support and reduced operator fatigue.
The instrument panel has been redesigned for improved visibility and usability. The easy to read gauges, warning lights and digital display ensure the operator is always aware of vital machine functions.
New electro-hydraulic controls provide quick steering response, precise blade control, and comfortable, low-effort operation. They offer superior ergonomics and are quieter and cleaner than pilot controls, eliminating hydraulic connections in the cab.
The AccuGrade Attachment Ready Option (AccuGrade ARO) provides a factory installed on-board platform for an AccuGrade Laser, GPS or Advanced Tracking Sensor (ATS) system. All of the changes required to the electrical system, hydraulic system, blade, and cab are incorporated into the AccuGrade ARO. Mounting brackets on the blade allow easy installation of the masts. Mounting brackets in the cab secure the in-cab display. Plug-in points inside the cab and on the front of the machine make it easy to install electronic components.
AccuGrade GPS System
The AccuGrade Global Positioning System (GPS) is the best solution when the construction site involves contours, rather than single or dual slope planes. A GPS system compares the blade position to a three-dimensional computerized job site plan and signals the operator or hydraulic system to raise or lower the blade to achieve the design requirements.
AccuGrade ATS System
The AccuGrade ATS system tracks blade positioning and provides three dimensional controlling capability for precise elevation adjustment, improved accuracy and dynamic tracking.
AccuGrade Laser System
The laser system is ideal for fine grading sites with flat, single slope or dual slope surfaces such as industrial, commercial and residential building sites.
The in-cab display with easy-to-read grade indicators and real time operator information provide the operator with all AcuuGrade system information. The display is designed for reliable performance in extreme operating conditions including shock, dust and moisture.
The VPAT blade gives the operator the ability to hydraulically adjust the blade lift, angle and tilt from the operator’s station.
Manually adjustable blade pitch for optimum performance.
Top corners of the blade are clipped for better operator viewing area. (XL arrangement only).
C-Frame is solidly pinned to the mainframe for good blade control and eliminates blade motion due to track oscillation or side forces.
Designed to facilitate transportation without removing the blade, the foldable blades reduced overall shipping width of the machine. The blade can be folded by hand by one person without the need for tools, and each foldable blade includes the mounting brackets for AccuGrade masts.
The D6N can be equipped with a drawbar for pulling work tools such as disks, compactors, chopper wheels and retrieval of other equipment.
The multi-shank parallelogram ripper lets you choose one, two or three shanks depending on job conditions. Curved or straight ripper shanks are available.
Standard and slow-speed winches are available to match the application requirements.
Integrated electronic controls for both clutch and brake functions improve winch performance.
Clutch engagement and brake release are automatically synchronized for smooth operation.
Winch components can be serviced with winch mounted on tractor.
Check with your Caterpillar Dealer for details.
In forestry and land clearing applications where limbs and debris can damage a machine, optional sweeps are available for the D6N. Sweeps help to shield critical components on the tractor such as hydraulic lines, exhaust stacks, cab windows and lights from damage.
Includes factory-installed hydraulics, wiring and ripper controls in a customized ripper control console.
Winch Ready Package
Includes factory-installed wiring and winch controls in a customized winch control console.
Heavy Duty Guard Package
Includes heavy duty guards for both the fuel tank and the crankcase, and a heavy duty hinged, louvered radiator grill with latch.
Cold Weather Package
Includes a coolant heater and high-capacity (1400 CCA) heavy-duty batteries for improved cold start capability.
Includes fast fuel and high speed oil change capability.
Semi-Universal Blade Package (Cab)
Built for tough applications where penetration and blade side loading are important. The design of the SU blade makes it excellent for aggressive dirt penetration and loading materials. The blade wings are designed for superior load retention.

Hinged engine doors provide easy access to secondary fuel filters, oil filters, engine oil filler tube, engine air filter, and the A/C compressor. Service doors provide easy access to the battery disconnect switch, hydraulic taps, transmission oil tank filler cap, windshield washer tank and batteries, emergency shut off switch, electronic control module, and the hydraulic case drain filter. Grouped pressure taps allow for quick testing and troubleshooting of the hydraulic system.
Product Link automatically reports machine information such as location, machine hours, service meter hours, machine condition and security alarms. All this allows for much better fleet management and maintenance.
Machine Security System (MSS)
An optional Machine Security System (MSS) utilizes a programmable key that deters theft, vandalism and unauthorized usage.
