A Cat C15 ACERT engine gives you the power and reliability you need
to get the job done. Fuel economy, plus efficient use of Diesel Exhaust
Fluid (DEF) gives you excellent overall fluid efficiency.
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. You also get better load
capacity, power and speed control in soft conditions because
both tracks are powered during turns.
Load Sensing Hydraulics
Field-proven load-sensing hydraulics continuously adjust hydraulic
power based on load to maximize your work tool. Independent
hydraulic pumps ensure no sacrifice in performance when steering
and controlling blade simultaneously.
Torque Divider
A single stage torque divider sends 70 percent of engine torque
through a converter and the other 30 percent through a direct drive
shaft so you get more power to the ground, more efficiently.
Cooling System
The radiator, Air To Air Aftercooler (ATAAC) 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. Six fins per inch on the standard
core allow debris to pass through and help reduce plugging.
In cooler conditions, the hydraulic demand fan reduces speed to
conserve power, save fuel and decrease sound levels. An optional
reversing fan is available for high debris conditions.

Power and Performance
Built to get the job done
Advanced Productivity Electronic Control
System (APECS)
The Planetary Power Shift Transmission uses integrated
electronic controls to automatically modify shift points based
on load and operating conditions. The result is smoother
shifting overall, as well as greater benefits from Enhanced
Auto Shift.
Enhanced Auto Shift
Enhanced Auto Shift is a standard feature that allows your
operator to select the optimum ground speed for the job.
It also helps you save fuel by automatically choosing the
most efficient gear based on load.
Selectable Electro-Hydraulic Maps
Customizable E-H maps allow you to set the implement
response/speed levels to match operator preferences
and tailor the machine to individual applications.
5
Operator Environment
Comfort and productivity
The latest D8T offers operators added comforts like a quieter cab, adjustable armrests
and a heated/ventilated seat option. A seat belt indicator light helps remind you to work
more safely.
A color touch-screen display puts the machine’s programmable control features right at
your fingertips. Control exterior lighting, activate the reversing fan and set productivity
features like Autocarry™, Auto Rip and Enhanced Auto Shift. You can also access machine
performance settings, diagnostics and much more. For complete information about functions
and programming, please see the D8T Operation and Maintenance Manual.
Implement and Steering Controls
• A single ergonomic handle with a thumb roller controls direction, turning, forward/
reverse shifting and gear selection. Tiller style control helps you work more precisely
in tight spaces.
• Low-effort dozer lever with electro-hydraulic controls helps you work more comfortably
and get precise work tool control. When equipped, single-handle convenience also
controls functions like AccuGrade and Dual Tilt.
• A ripper control with rigidly mounted hand grip provides firm support for the operator
even when ripping in the roughest terrain.
• Implement Lock-Out prevents inadvertent operation of hydraulic attachments when
activated by the operator or automatically when the operator is not present.
6
Emissions Technology
Proven, integrated solutions
Emissions reduction technology on the D8T is designed to
be transparent, with no action required from the operator.
Regeneration runs automatically in the background while you work.
Diesel Exhaust Fluid
Selective Catalytic Reduction utilizes Diesel Exhaust Fluid (DEF),
which can be conveniently refilled when you refuel. A gauge on the
dash shows your fluid level. The D8T offers excellent fluid efficiency.
Across a variety of applications, the D8T typically has used DEF at a
rate of 2-3 percent of fuel consumption.
When the machine is turned off, a pump will automatically purge the
DEF lines to help prevent the fluid from freezing in the lines and pump.
A symbol on the dash and a light/symbol on the Ground Level Service
Center indicate when the purge is complete and that it is safe to turn
off the electrical disconnect. If the engine/aftertreatment temperatures
are high, a delayed engine shutdown will activate automatically to
cool the machine and then purge the lines. For complete aftertreatment
information, please refer to your machine’s Operation and
Maintenance Manual.

Cat Connect Technologies
Monitor, manage, enhance job site operations
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.
Cat Slope Indicate („) – displays machine cross-slope and fore/aft
orientation, helping operators work more accurately on slopes.
Cat Grade with 3D (z) – factory-integrated grade control system that
enables operators to improve grading efficiency, accuracy and productivity.
The system automates blade movements in both fine grading and
production dozing applications, reducing manual operator inputs by
as much as 80 percent.
Integrated design moves the antennas to the top of the cab, eliminating
masts and cables traditionally on the blade. 3D mapping of blade and
tracks reduces the need for grade checkers and staking, enhances
safety and reduces labor costs.
Cat AccuGrade (z) – dealer-installed aftermarket grade control system
provides higher accuracy capabilities by adding laser, GPS and UTS
technology when required. Factory AccuGrade Ready Option provides
optimal mounting locations, brackets, and hardware and simplifies
installation.
Auto Blade Assist (z) – increases efficiency while reducing
operator workload. ABA makes use of preset blade pitch positions
for the load, carry, and spread portions of the cycle.
AutoCarry (z) – automates blade lift to maintain desired blade load,
improve load consistency, and reduce track slip. Works seamlessly
with GRADE with 3D.
Automatic Ripper Control (z) – automatically controls ripper height
to limit track slip in hard ripping applications.
(„) = Standard
(z) = Optional

COMMAND for Dozing
When dozers work in hazardous mining and
earthmoving applications, remote control
dozing helps improve safety and efficiency by taking
operators off of their machines and letting them work from
either nearby or remote locations. Optional COMMAND
for Dozing is deeply integrated with Cat machine systems
to enable smooth, precise control for maximum efficiency
and productivity.
• Over-the-shoulder operator console provides line-of­
sight remote control operation from up to 400 meters
(437 yd) away.
• Comfortable remote operator station offers both line-of­
sight and non-line-of-sight remote control.

Equipped for the Job
Tough from the inside out
Bulldozers
High tensile strength steel, with a strong box-section design,
stands up to the most severe applications. Heavy moldboard
construction and hardened bolt-on cutting edges and end bits
add strength and durability. Optional rock guards and standard
deflector shields help protect cylinders.
The Tag-Link brings the blade closer to the machine for precision,
lateral stability and constant breakout force, regardless of the
blade height.
Optional Dual Tilt improves load control and allows the operator
to optimize the blade pitch angle for better balance and
productivity. Tilt the blade forward for better penetration, then
tilt back to increase carrying capacity. Auto Blade Assist is
standard with Dual Tilt to increase efficiency and reduce
operator workload.
Blades and Performance Cutting Edges
High-Capacity Universal, Semi-Universal (SU) and Angle Blades
are available, as well as special blades for coal and woodchip
stockpile applications. A new, larger SU blade option offers
19 percent more capacity (10.3 m3/13.4 yd3) to help you move
more material per pass.
The new blade features patented Performance Cutting Edges
designed to help you work faster in hard/frozen ground or in
moderately rocky applications. The cutting action increases
blade load mass to move more material per pass. Blade control,
load retention and traction are improved. The dozer digs
deeper and ripping may be reduced in some situations.
Performance Cutting Edges are interchangeable with
traditional cutting edges, and offer the same wear life/life cycle
cost without the need to flip. For added versatility, the plane of
the end bits enables finish grading.
10
Undercarriage
The D8T is built on a tough mainframe designed to absorb high impact shock loads and twisting forces. A fully suspended
undercarriage provides more ground contact, especially in hard, uneven terrain. Greater traction means less slippage, better balance
and a smoother ride. The elevated sprocket design helps protect major components from harsh impacts and provides a modular design
that is convenient to service.
Heavy Duty undercarriage is standard and is well suited to aggressive applications like land clearing, side-slopes, or working in rocky
or uneven terrain.
New, optional Cat Heavy Duty Extended Life Undercarriage is designed to help reduce your costs with heavier bushings for up to
30 percent more wear life. Patented crowned Dura Link is hardened for longer life and reduced scalloping, which improves ride after
50 percent link wear. The Extended Life Undercarriage is best suited to high abrasion conditions and features matching component
wear life for easier maintenance.*
Rear Implements
To help match your dozer to the task at hand, you can outfit your D8T with a single-shank ripper, multi-shank ripper, winch, drawbar
or rear counterweights. Ask your Cat dealer for available options to help you optimize your machine for the work you do.
