The durable construction of the D9T is well suited for
tough working conditions. It has excellent productivity,
optimal operator comfort and robust reliability. Today’sD9T
will help you meet your businessobjectivesevery day.

C18 Engine with ACERT™ Technology

Power and reliability

C18

Performing at full-rated net power of 306 kW (410 hp),
thelarge displacement and high torque rise allow the D9T
toripthrough tough material. Matched to the high-efciency
torque converter and electronically controlled power shift
transmission, it will provide years of reliable service.

ADEM™ A4 Engine Controller

Manages fuel delivery for optimal performance per liter
(gallon) of fuel used. Provides exible fuel mapping,
allowing the engine to respond quickly to application
needs.Tracksconditions and keeps engine operating
at peak efciency.

ATAAC and Airow

Air-to-air aftercooling keeps air intake temperatures down
and, in concert with the tight tolerance combustion chamber
components, maximizes fuel efciency and minimizes emissions.
Signicant improvements in air ow are generated by a
water-cooled turbocharger, unique cross-ow head and
singleoverhead cam.

Turbocharging and Air-to-Air Aftercooling

Provides high horsepower with faster response time while
keeping intake temperatures low for long hours of
continuous operation.

Fuel Heater (optional)

Uses the temperature of the engine coolant to warm the cold
fuel coming directly from the tank. The fuel heater allows an
easier transition to winter blended fuels during season changes.

High Altitude Arrangement (optional)

New with the D9T is an optional high altitude arrangement.
The attachment provides an updated turbo and control
software that allows full tractor performance up to 4420 m
(14,500 ft) altitude.

Cooling System

Durable and efcient

Aluminum Bar Plate Radiator

Cooling system uses a radiator built with rugged, highly efcient aluminum bar plate cores.
Thealuminum bar plate construction aids durability and allows for higher heat transfer and superior
corrosion resistance.

Hydraulic Air to Oil Cooler

The new air to hydraulic oil cooler reduces hydraulic oil temperatures improving component life.
Thecore is built using the same rugged aluminum bar plate design as the jacket water cooler. It is
designed in-line with the water cores to minimize debris plugging in allapplications.

Hydraulically Variable, Demand Fan

Provides engine cooling capability that is matched to theambient conditions. In cooler conditions,
thefan turnsat a slower speed, reducing power demands. Thisreduces fuel consumption in lower load
factor operations. Lowspeed fan operation also reduces both operator andspectator sound levels.

Attachments

• Ultra low speed option for cold weather applications

• Reversing cooling fan forheavy debris applications

Operator Station

Comfort and convenience

The D9T cab is designed and equipped for operator productivity,
safety andcomfort. The standard isolation-mounted cab
reduces noise and vibration. Overall operator sound levels
have been reduced by 2 dB(A). Largewindows, tapered hood,
and notched fuel tank provide excellent visibility to all sides
of the machine and around the job site.

The D9T comes with an updated in-dash display with new
features. An improved Advisor Monitoring System tracks
machine operating conditions in real time. Dimmable lights
allow the operator to choose between night and day backlight
settings, through Advisor, to adjust the brightness of all
switches and thekeypad in the cab.

Operators will enjoy comfort features like standard
CatComfort Series Seat, adjustable arm rests and automatic
climate control. The climate control system automatically
adjusts heater and air conditioning controls to maintain a
consistent cab temperature throughout the day. Both heater
and air conditioner deliver ltered, pressurized, temperature
controlled air to the operator and/or windows. Thesystem
performs 5 functions: heating, cooling, defrosting,
pressurizing and defogging.

Additional cab features include:

• Entertainment radio ready and IPOD/MP3 player ready

• Communications radio mounting

• Finishes that make the cab easy to clean

• Heated and ventilated seat option

• Deep storage space

• Two cup holders

• Window wipers (intermittent, low and high speeds)

Implement and Steering Controls

Ergonomically designed for ease of operation

Dozer Control Lever

A low-effort electronic dozer control handle gives the
operator control of all dozer functions with one hand.
Fore/aft movement of the control handle lowers and raises
the blade. Left/right movement directionally tilts the blade.
Blade response and blade oat can be set/adjusted using the
Advisor System.

The thumb lever at the top of the handle and trigger switch
controls blade pitch fore and aft when equipped with dual tilt.
Dual tilt also provides automated blade assist control capability.

Electronic Ripper Control

A rigidly mounted handgrip provides rm support for
the operator even when ripping in the roughest terrain.
The low effort thumb lever controls raising and lowering.
The nger lever controls shank-in and shank-out positioning.

Performance Monitor

The monitoring system collects machine data and provides
real-time feedback on machine productivity to optimize
performance. Data summaries can be sent to off-board tools
for site managers to review.

Terrain for Grading (optional)

Provides high precision management of dozing and grading
applications for enhanced safety, productivity and efciency.
The system enables an electronic site plan to be sent to the
machine from the ofce in real-time, directing the operator
where to cut and ll.

Automatic Ripper Control (optional)

A new feature that reduces operator fatigue and decreases
wear and tear on the machine. This is done by monitoring
thetractor ground speed with the new cab mounted Global
Navigation Satellite System (GNSS) to automatically adjust
engine speed and ripper depth to minimize track slip.

Autocarry (optional)

Enhances operators productivity by coninuously monitoring
ground speed and automatically adjusts blade load.

Cat Grade Control (optional)

Integrates traditional machine control and guidance with
machine hardware and software to help improve productivity,
usability, reliability and value.

Cat Grade Control software is enhanced to not only
automatically guide the blade to the desired design contours,
but also integrated with Autocarry to sense and automatically
control the load of the blade for improved performance and
efcient blade loading in high production dozing applications.
