The D6N has earned reputation of being the machine
thatcan be trusted to perform. It keeps material moving
with the reliability, durability and comfort you expect
from Cat® machines. It is engineered to excel on the most
demanding worksites and in every job – from production
dozing to ne grading.

The new D6N not only combines this proven reliability
with technologies reducing emissions. Itfurther improves
fuel efciency and productivity, all the more when
equipped with the latest technologies for which it
isanexcellent platform.

Today’s D6N is the best choice for customers in need of
aversatile, easily transportable machine to do the job and
help them meet their business objectives atalower cost.

Operator Station

Designed for comfort, safety and high productivity

An isolation-mounted pressurized cab reduces dust entry,
noise and vibration. Large glass panels provide excellent
visibility. Intermittent wipers maximize visibility in poor
weather conditions. Heating and air conditioning controls
are conveniently located. Temperature control is automatic.

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.

Engine

Power and reliability

The D6N features a Cat C6.6 ACERT™ engine and a
CatClean Emission Module to deliver the performance
that customers demand, while meeting U.S. Tier 4 Interim,
EU Stage IIIB and JapanMLITStep 4 emission standards.

The Cat C6.6 is an in-line congured engine. The ACERT
Technology features advanced electronic control, precision
fuel delivery, rened air management and aftertreatment
technologies. The system is optimized based on engine size,
the type of application and the geographic location in
which it will work. To assure that our Tier 4 Interim
technology will meet our customers expectations for
reliable trouble-free service, we subjected these products
toover one million operating hours of test and validation
before sale of the rst Tier 4 Interim machine.

Emissions Technology

Reliable and transparent integrated solutions

Cat NOx Reduction System

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.

Aftertreatment Technologies

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 simpli es 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.

Cat Low Temperature Regeneration System

The low temperature Passive Regeneration system works
transparently, without any interaction needed from the
operator. Under most conditions, engine exhaust will remove
soot through passive regeneration. If supplemental regeneration
is needed, the system will automatically activate the exhaust
back pressure valve to supplement regeneration. This will
result in burning off soot in the DPF.

The Cat Low Temperature Passive Regeneration System
allows fast and accurate control of regeneration independent
of engine exhaust temperatures, even in case of low load
application or cold ambient temperatures.

Engine Idle Shutdown Timer – This option (when activated
bythe operator) shuts down the engine after the machine
hasbeen idling for a pre-set period of time.

Automatic Engine Speed Control (AESC) – It reduces engine
speed when the machine is not under load for more than
veseconds, which can help reduce fuel consumption
signicantly depending on the application.

Powertrain

Efcient, smooth and responsive power

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.

High Efciency Torque Divider

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 efciency and driveline reliability.

Differential Steering System

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.

Multi Velocity Program (MVP)

Maximize your production and fuel efciency with this exclusive feature, which let you choose from
different engine speed ranges to best match your applications and ground conditions.

ECO Modes

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.

Implement and Steering Controls

Ergonomically designed for ease of operation

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 prole in the display.

Steering and Transmission Controls: All in One Hand

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.

Dozer and Rear Attachment Control Levers

• Dozer Control Joystick. The lever allows six-way control

ofthe VPAT blade and the thumb rocker adjusts the
blade angle. Standard electro-hydraulic control means
simplied installation of the AccuGrade™ system.

• Integrated Ripper/Winch Lever. Rear attachments are

controlled by the same lever and controls can be
pre-congured for a ripper, a winch or both of them.

Throttle Rocker Switch

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.

Implement/Work Tool Lock-Out Switch

Lock-out feature prevents inadvertent operation of hydraulic
work tool attachments.

Auto-Shift/Auto-Kickdown Switch

The Auto-Shift function allows a pre-selection of four forward
and reverse speed settings that will occur automatically for
easy, efcient directional changes. Auto-kickdown allows the
transmission to automatically downshift when signi cant
loadincreases are detected, maximizing your productivity.
