Power and Performance


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.

Differential Steering


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.

Cooling System


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.

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.

Advanced Productivity Electronic Control System (APECS)


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.

Enhanced Auto Shift


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.

Operator Environment


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.

Implement and Steering Controls


Emissions Technology


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.

Diesel Exhaust Fluid


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


Cat Connect makes smart use of technology and services to improve your job site efficiency. Using the data from technology equipped machines, you'll get more information and insight into your equipment and operations than ever before.

Cat Connect services are also available from your dealership including:

Equipment Management – increase uptime and reduce operating costs.

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.

GRADE for Dozers


Cat Slope Indicate (Standard) – displays machine cross-slope and fore/aft orientation, helping operators work more accurately on slopes.

Cat Grade with 3D (Optional) – 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 (Optional) – 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 (Optional) – 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 (Optional) – automates blade lift to maintain desired blade load, improve load consistency, and reduce track slip. Works seamlessly with GRADE with 3D.

Automatic Ripper Control (Optional) – automatically controls ripper height to limit track slip in hard ripping applications.

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.

LINK Technologies
LINK technologies provide wireless capability to machines enabling two-way transfer of information collected by on-board sensors, control modules, and other Cat Connect technologies using off-board apps, such as our VisionLink® software.

Product Link™/VisionLink
Product Link takes the guesswork out of equipment management. Track location, hours, fuel usage, productivity, idle time, and diagnostic codes through the online VisionLink interface. Manage your fleet in real time so you can maximize efficiency, improve productivity, and lower operating costs.

Equipped for the Job


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.

Bulldozers


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.

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.
