An isolation-mounted pressurized cab reduces dust, noise and vibration. Large glass panels provide excellent visibility. Intermittent wipers maximize visibility in poor weather conditions. Cab (ROPS) mounted air conditioning gives you more cooling capability, and removes the condenser from under the hood so it is easier to service. Updated dash and instrumentation streamline the display in a format that is more common across the Cat tractor line and keep the operator aware of any important information in his own language. Brightness and contrasts can be adjusted. Fully adjustable, the air suspended seat includes bolsters to restrain side-to-side movement and steep slope footpads ensure a comfortable position when working on slopes. The cab is pre-wired for a radio and includes two speakers, an antenna and a radio mount. A 10-Amp, 12-volt power converter provides supplemental power for cellular phones or two way radios. The cab also features convenient storage compartments, a cup and coat holder.
The D6N features a Cat C6.6 ACERT engine and a Cat Clean Emission Module to deliver the performance that customers demand. The Cat C6.6 is an in-line configured engine. ACERT Technology is a combination of building blocks that includes electronics, fuel systems, air management systems and aftertreatment components. The system is optimized based on engine size, the type of application and the geographic location in which it will work. The technologies are applied systematically and strategically to meet high customer expectations for productivity, fuel efficiency, reliability and service life.
The Cat NOx Reduction System captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
Cat aftertreatment components have been designed to match application needs. System components include a Diesel Oxidation Catalyst (DOC), which uses a chemical process to convert regulated emissions in the exhaust system, and a Diesel Particulate Filter (DPF) that traps and removes soot until burnt off through regeneration. The DOC and DPF are contained in the Clean Emissions Module (CEM) that protects the components and simplifies maintenance. The CEM will control if regeneration needs to occur and soot level is monitored through the display. The aftertreatment is designed to remove particulate matter from the exhaust without the need for operator intervention or work cycle interruption.
The low temperature Passive Regeneration system works transparently, without any interaction needed from the operator. Under most conditions, engine exhaust temperature will oxidize soot through passive regeneration. In certain operating conditions, when exhaust temperatures might not be high enough, a back pressure valve automatically increases engine load, therefore restoring necessary exhaust temperature. This ensures transparent regeneration even at low temperatures or low load factor.
This option (when activated by the operator) shuts down the engine after the machine has been idling for a pre-set period of time.
It reduces engine speed when the machine is not under load for more than five seconds, which can help reduce fuel consumption significantly depending on the application.
The power shift transmission and differential steering work in tandem with the engine to deliver the power, productive performance and reliability expected from Cat track-type tractors.
The torque divider acts as a hydrodynamic component between the engine and transmission to provide high multiplication of torque and attain the best combination of operating efficiency and driveline reliability.
Differential steering maintains full power to both tracks to provide best-in-class turning with a loaded blade. When one track speeds up, the other slows down an equal amount. Maneuverability is improved, as well as cycle times in some applications.
Maximize your production and fuel efficiency with this exclusive feature, which let you choose from different engine speed ranges to best match your applications and ground conditions.
Standard Eco Modes (when activated) automatically reduce engine speed and are suited for light to medium loaded applications. Operators can select either the “reverse only” or the “forward and reverse” mode. Eco Modes can help save up to 25% of fuel depending on the application.
All controls are electro-hydraulic, which means precision and maneuverability. They are ergonomically designed for easy intuitive, comfortable and low effort operation. Blade response can be adjusted through the operator profile in the display.
Differential steering controls give the maneuverability and precision needed in close areas or around structures. The single handle controls the direction (FNR switch) and degree of turns, forward-reverse shifting and gear selection. The thumb roller shifts the electronically controlled transmission and its Ground Speed Adjustment function enables precise speed control. The Speed Recall function allows you to easily save and recall the speed (forward) you want to operate with.
Press the Throttle Rocker switch, it will adjust the engine speed to high or low idle. Press and hold until desired engine speed is attained and then release, the machine will maintain this new chosen speed.
Lock-out feature prevents inadvertent operation of hydraulic work tool attachments.
The Auto-Shift function allows a pre-selection of four forward and reverse speed settings that will occur automatically for easy, efficient directional changes. Auto-kickdown allows the transmission to automatically downshift when significant load increases are detected, maximizing your productivity.
The dealer-installed AccuGrade system automates blade movements and accurately guides the operator to grade, reducing manual operator inputs as much as 80 percent. Experienced operators can maintain peak efficiency levels throughout the work day, and less experienced operators can be more productive faster. AccuGrade reduces grade checking and staking, labor and material costs, and improves job site safety. Caterpillar offers a choice of Laser for 2D flat planes and slopes, Global Navigation Satellite System (GNSS) for complex 3D cuts/contours, and/or Universal Total Station (UTS) for fine and finish grades.
The factory AccuGrade Ready Option provides optimal mounting locations, brackets, and hardware to make the AccuGrade installation quick and easy. Deep integration optimizes machine and system performance and productivity.
The D6N with AccuGrade now includes the Rough Grade function; it allows the operator to manually control tilt as long as the center of the blade is above design, while the AccuGrade system controls the blade height. When the blade center reaches the grade, an auto-lift control prevents the blade from going further down. This can increase your performance when operating manually.
Product Link is deeply integrated into your machine, helping to take the guesswork out of equipment management. Easy access to timely information like machine location, hours, fuel usage, idle time and event codes via the online VisionLink user interface can help you effectively manage your fleet and lower operating costs.
The radiator, air-to-air aftercooler and hydraulic oil cooler are packaged in a single plane, making cleanout easier. Durable, aluminum bar plate construction gives you superior heat transfer and corrosion resistance. 8.9 fins per inch (6.5 fpi on Waste Handlers) on the standard core allow debris to pass through and help reduce plugging. In cooler conditions, an engine mounted demand fan reduces speed to conserve power, save fuel and decrease 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.
The D6N features the elevated sprocket design that isolates final drives, axles, and steering components from harsh impacts. The modular design aids to reduce maintenance costs. A variety of undercarriage configurations and track shoe designs help optimize performance.
SystemOne can help reduce owning and operating costs in many applications. Lifetime sealed and lubricated cartridges eliminate bushing turns and sprockets require no replacement during the life of the chain. All SystemOne undercarriage components are designed to work and wear as a system for longer track life.
Heavy duty undercarriage is well-suited to aggressive applications like land clearing, side-slopes, or working in rocky or uneven terrain. Components are designed for extended wear life in abrasive conditions and high impact applications.
The XL version performs well in applications with firm to soft underfoot conditions. The LGP undercarriage is designed for soft and swampy conditions. The XL Fine Grading version combines the LGP roller frame length with XL shoes for finish grading applications. All machines now have a stiffer equalizer bar, which enhances finish grading capabilities.
Field-proven, load-sensing hydraulics respond to operating requirements by automatically and continually adjusting hydraulic power to maximize work tool efficiency.
The D6N features a new large spherical linkage bearing for an easier blade removal. Linkage bearings are designed for the life of the machine. VPAT blades now come AccuGrade Ready from factory with mounted brackets for AccuGrade receivers. AccuGrade angle sensor are better protected in the new centered position. Strong design allows Cat blades to stand up to the most severe applications.
This blade allows the operator to adjust the blade lift, angle and tilt simultaneously, using the same control. The blade pitch can also be adjusted, which can help increase productivity. Changing the blade pitch angle is now easier with the new pitch system. The versatility of the VPAT blade gives the D6N the ability to take on a variety of applications and material conditions, such as finish grading, spreading material or backfilling. Full track coverage can be achieved in one pass.
Designed to facilitate transportation without blade removal, foldable blades reduce the overall shipping width. The blade can be easily folded without the need for tools, and its design has been improved to make the folding process easier and quicker, with only one pin left to remove.
This blade is built for tough applications where penetration and capacity are important. L-shaped push arms bring the blade closer to the machine, providing excellent maneuverability, balance and stability. When end bits are removed, the blade width reduces to 3 m (9.8 ft) to allow easier transportation.
Parallelogram linkage design allows for better penetration and maneuverability in tight working areas.
For improved winch availability and configuration flexibility, dealers may order the D6N with a factory installed winch preparation package to allow the winch to be easily installed in the field. A single lever control actuates both clutch and brake functions to help improve operator efficiency. See your Cat dealer for available winch options. A dual control package is also available for machines that can be fitted either with a ripper or a winch.
The D6N can be equipped with a drawbar for retrieving other equipment or pulling work tools such as discs, compactors, or chopper wheels.
