Benefits & Features
Power and Performance
Built to get the job done
A Cat C9.3 ACERT engine gives you the power and reliability you need to get the job done. Improved fuel economy over Tier 4 Interim and efficient use of Diesel Exhaust Fluid (DEF) gives you excellent overall fluid efficiency.
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 system senses the load and continuously adjusts hydraulic power to your blade to maximize efficiency.
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.
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. Six fins per inch on the standard core allow debris to pass through and help reduce plugging. A standard perforated grill helps protect the 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.
Enhanced Auto Shift
Standard Enhanced Auto Shift helps you save fuel by automatically upshifting/downshifting to maintain the most efficient gear based on load. Three different modes (3-, 6-, 9-speed), plus additional fine ground speed adjustment, allow you to optimize tractor performance to match material and job site conditions.
Selectable Electro-Hydraulic Maps
Selectable Electro-Hydraulic Maps set the implement response levels – fine, medium, coarse – to match operator preferences and tailor the machine to individual applications.
Comfort and productivity
The latest D6T offers operators added comforts like a quieter cab, easy closing cab doors, a heated/ventilated seat option, manually adjustable armrests and a cup holder with auxiliary power port.
New cab (ROPS) mounted air conditioning gives you more cooling capability, and removes the condenser from under the hood so it is easier to service.
The in-dash display monitors machine conditions in real time. The panel is glare-resistant and illuminated for low-light visibility.
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 precisely in tight spaces.
Electro-hydraulic controls are standard on the D6T. Low effort controls give you precise control of the blade and rear attachments, as well as easy 6-way control of a VPAT blade.
A variable throttle control dial lets you use preset engine speeds, customize engine speeds for operator preference or utilize Auto Shift modes.
Bi-directional shift allows you to automatically select the desired forward/reverse gears and forward/reverse speeds when Enhanced Auto Shift is activated.
Implement Lock-Out prevents inadvertent operation of hydraulic attachments.
Proven, integrated solutions
Emissions reduction technology on the D6T is designed to be transparent, with no action required from the operator. Regeneration runs automatically in the background while you work.
Caterpillar designed Tier 4 Interim products with Tier 4 Final standards in mind. To meet the additional 80 percent reduction in NOx emissions required at Tier 4 Final, Caterpillar engineers added Selective Catalytic Reduction (SCR) to the already proven aftertreatment solution.
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. 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.

Equipped for the Job
Optimize your machine
Your choice of undercarriage, track shoes, blades and rear implements help you outfit your machine for optimum performance and service life. L-shaped push arms give you an advantage over diagonal brace designs by bringing the blade closer to the machine. This gives you better balance, maneuverability and blade penetration. The design also gives you lateral stability and better cylinder positions for constant pryout capability regardless of blade height.
The D6T features the Caterpillar elevated sprocket design that helps protect major components from harsh impacts and provides a modular design that is convenient to service. Choose Heavy Duty undercarriage for aggressive applications like land clearing, side-slopes or rocky terrain. Or, choose SystemOne™ undercarriage that is designed to work and wear as a system for longer life and lower costs in many applications. A broad choice of track shoe designs and widths help you further optimize your machine for performance and longer life.
Semi-Universal, Straight and Angle blades are designed with a strong box section to stand up to the most severe applications. Heavy moldboard construction, hardened bolt-on cutting edges and end bits add strength and durability. The Variable Pitch Angle Tilt (VPAT) blade allows you to hydraulically adjust lift, angle and tilt for precise results. The VPAT blade is wider to take on a variety of applications so you can use your D6T for spreading material, finish grading, side casting, V-ditching and backfilling. The VPAT blade can also be angled for easy shipping.
To help you match your D6T to the task at hand, you can outfit your D6T with a multi-shank ripper, winch, drawbar or rear counterweight.
Ask your Cat dealer for available options to help you optimize your machine for the work you do.
