Benefits & Features
The D6T cab is designed and equipped for operator productivity, safety and comfort. An isolation-mounted cab reduces noise and vibration. Large single-pane windows, tapered hood and notched fuel tank provide excellent visibility to all sides of the machine and around the job site.
Updated dash and instrumentation streamline the display in a format that is more common across the Cat tractor line. A display mount is integrated into the dash for a grade control system, placing job site data conveniently in front of the operator.
A standard air-ride suspension seat is well padded and adjustable, with bolsters to comfortably restrain operator side-to-side movement when working on grades or slopes. Armrests are adjustable. Heating and air conditioning controls are located in the headliner for easy access, and conveniently located air vents evenly distribute airflow within the cab.
The cab is pre-wired for a radio and equipped with two speakers, an antenna and a radio mount recessed in the headliner. Two 10-amp, 12-volt power converters are also included for supplemental power for cellular phones and computers. The cab interior features a convenient storage compartment in the dash.
The D6T features a Cat C9.3 ACERT™ engine and a Cat Clean Emissions Module to deliver the performance and efficiency that customers demand, while meeting U.S. EPA Tier 4 Interim/EU Stage IIIB emission standards.
The six-cylinder electronic engine is turbocharged and aftercooled. The displacement produces better lugging capability, lower internal stresses and longer component life.
ACERT™ Technology is a combination of building blocks that includes electronics, fuel systems, air management systems and aftertreatment components. The system is optimized based on engine size, the type of application and the geographic location in which it will work. The technologies are applied systematically and strategically to meet high customer expectations for productivity, fuel efficiency, reliability and service life.
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
To meet Tier 4 Interim/Stage IIIB emission standards and beyond, 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 particulate matter that is carried into the exhaust stream.
The DOC, DPF and Cat Regeneration System are contained in a Caterpillar designed Clean Emissions Module (CEM) that protects the components, minimizes the aftertreatment footprint and simplifies maintenance. For high debris applications that require thermal shields on exhaust components, an optional insulated CEM is available for the D6T (available late 2011).
Cat Regeneration System
The Cat Regeneration System is designed to work transparently, without any interaction needed from the operator. Under most operating conditions, engine exhaust is hot enough to oxidize soot through passive regeneration. If supplemental regeneration is needed, the Cat Regeneration System elevates exhaust gas temperatures to burn off soot in the Diesel Particulate Filter (DPF). This is a process that happens automatically, but the operator can initiate the cycle when convenient or interrupt regeneration as needed. A soot level monitor and regeneration indicator lights are integrated into the D6T dash display.
The power shift transmission and differential steering work in tandem with the C9.3 ACERT engine to deliver the outstanding power, productive performance and reliability expected from Cat track-type tractors.
Torque Divider
A single-stage torque divider sends 70 percent of engine torque through a converter and 30 percent through a direct drive shaft for greater driveline efficiency and higher torque multiplication. This provides an optimum combination of operator efficiency 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 – especially with large blade loads – is improved, as well as cycle times in some applications. Greater load capacity, power and speed control are possible in soft underfoot conditions on steep slopes because both tracks are powered during turns. Low effort tiller bar, touch shift control and steering modulation ensure ease of operation.
Multi Velocity Program
This exclusive machine control system allows the operator to choose from five speed ranges in Forward and Reverse to best match machine speed to applications and ground conditions. Operators maximize production, minimize fuel consumption, and reduce overall machine operating costs.
Cat Eco Reverse
The standard Eco Reverse feature reduces engine speed during the reverse portion of the dozing cycle. Once set, no additional operator input is needed. Eco Reverse can reduce fuel use by up to 5 percent, depending on the application.
The D6T utilizes electro-hydraulic differential steering. This steering method controls the direction and degree of turns, forward-reverse shifting, and gear selection in a single control handle, all enhancing operator comfort. A new control handle is ergonomically designed to reduce operator fatigue. The new thumb roller on the steering control shifts the electronically controlled powershift transmission, while the FNR switch controls the machine travel direction. The tiller allows the operator to work precisely in close areas – around structures, grade stakes and other machines.
Dozer and Rear Attachment Control Levers
The D6T features ergonomically designed implement controls with low effort, electro-hydraulic controls for added operator comfort, easy operation and precise work tool control. Electro-hydraulic controls are now standard on the D6T, simplifying installation of an AccuGrade system. When equipped with a VPAT blade, the lever allows six-way control of the blade and the thumb rocker adjusts blade angle.
Throttle Rocker Switch
One touch of the throttle rocker switch automatically adjusts engine speed to high or low idle. A new feature allows the operator to press and hold until desired engine speed is attained, then release for the machine to maintain the new chosen speed.
Implement/Work Tool Lock-Out Switch
Lock-out feature prevents inadvertent operation of hydraulic work tool attachments.
Auto-Shift/Auto-Kickdown
Operators can pre-select a forward and reverse speed setting for easy, efficient directional changes. Auto-shift settings include first forward to second reverse and second forward to second reverse. Auto-kickdown allows the transmission to automatically downshift when significant load increases are detected.
Instrument Panel and Cat Monitoring System
The D6T features a new in-dash display with new functionalities. The advanced monitoring system tracks the machine operating conditions in real time. The monitoring system display is illuminated for excellent visibility in low light and is glare resistant for easier viewing in bright light. It also includes controls for brightness and contrast.

Grade Control Ready
The D6T comes standard from the factory Grade Control Ready (GCR) including deeply integrated harnesses incorporated into the machine during assembly. This integration allows for an easy dealer installed AccuGrade Ready Option (ARO) and AccuGrade machine control and guidance system later as business requirements change, or for improved resale value. The machine dashboard also includes space to install an AccuGrade display.
AccuGrade Ready Option
The D6T can be ordered from the factory with optional brackets and hardware installed, making the tractor ready to plug in the dealer installed AccuGrade machine control and guidance system. The factory installed ARO simplifies the dealer installation of the AccuGrade components and integration into the machine helps protect components to enhance system robustness.
AccuGrade
AccuGrade is a dealer installed machine control and guidance system which enables operators to cut and fill to grade with increased accuracy, minimizing the need for traditional stakes and grade checkers.
AccuGrade uses advanced Laser, Global Navigation Satellite System (GNSS) and/or Universal Tracking Station (UTS) technology, machine-mounted components and off-board hardware. This state-of-the-art machine control system provides precise elevation information on an in-cab display to achieve accurate blade positioning. By displaying real-time cut/fill information in the cab, operators can improve their efficiency and get to grade faster with fewer passes than ever before. The AccuGrade System significantly improves the productivity and accuracy of grading equipment – by as much as 50 percent over conventional methods.
Cat Product Link
Remote monitoring with Product Link improves overall fleet-management effectiveness. Product Link is deeply integrated into machine systems. Events and diagnostic codes, as well as hours, fuel, idle time and other detailed information are transmitted to a secure web based application, VisionLink™. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level and more.

The engine radiator, Air To Air After Cooler (ATAAC), and hydraulic oil cooler are packaged in a single plane. Aluminum bar plate construction provides durability and allows for higher heat transfer and superior corrosion resistance. The standard cores feature 6 fins per inch to allow debris to pass through and reduce plugging concerns.
In cooler conditions, a new hydraulically driven demand fan reduces speed to conserve power, save fuel, and decrease sound levels.
An optional reversing fan attachment changes the fan rotation while the machine is backing up or stationary. This attachment includes access slots in the side of the radiator guard for cleaning access. A ROPS mounted air conditioner is packaged with the reversing fan attachment for optimum fan purging and ambient capability.
The D6T features the Caterpillar elevated sprocket design that isolates final drives, axles, and steering components from harsh impacts. The modular design aids serviceability to help reduce maintenance costs. A variety of undercarriage configurations and track shoe designs help optimize performance and undercarriage life.
SystemOne™ Undercarriage
SystemOne can help reduce total undercarriage owning and operating costs in many applications. Lifetime sealed and lubricated cartridges eliminate bushing turns and sprockets require no replacement during the life of the chain. All SystemOne undercarriage components are designed to work and wear as a system for longer track life.
Heavy Duty Undercarriage (optional)
Heavy duty undercarriage is well-suited to aggressive applications like land clearing, side-slopes, or working in rocky or uneven terrain. Components are designed for extended wear life in abrasive conditions and high impact applications.
L-shaped push arms bring the blade closer to the machine than diagonal brace designs, providing excellent maneuverability, balance, and blade penetration. This design provides solid lateral stability and better cylinder positions for constant pryout capability independent of blade height.
Load Sensing Hydraulics
Field-proven, load-sensing hydraulics respond to operating requirements by automatically and continually adjusting hydraulic power to maximize work tool efficiency.
Cat Blades
Semi-Universal, Straight, and Angle Blade designs feature a strong box-section to stand up to the most severe applications. Heavy moldboard construction and hardened bolt-on cutting edges and end bits add strength and durability.
Variable Pitch Angle Tilt (VPAT) Blade
A Variable Pitch Angle Tilt (VPAT) blade on the D6T allows the operator to hydraulically adjust the blade lift, angle, and tilt simultaneously, using the ergonomically designed blade control. The operator also has the ability to manually adjust the blade pitch. The versatility of the VPAT blade gives the D6T the ability to take on a variety of applications and varying material conditions, such as finish grading, spreading material, side casting, V-ditching, and backfilling. VPAT blades are wider for more capacity and the ability to achieve full track coverage in one pass. VPAT blades can also be angled for ease of shipping.
The multi-shank parallelogram style ripper is offered with one, two, or three shanks to best suit job conditions. Curved or straight ripper shanks are available.
Winch
A single lever control actuates both clutch and brake functions to help improve operator efficiency. See your Cat dealer for available winch options.
Rear Counterweight
Optimize balance for backing up steep slopes or increasing performance in heavy dozing applications. Rear counterweights are recommended if another rear attachment is not specified, and are required with VPAT blades.
Drawbar
The D6T can be equipped with a drawbar for retrieving other equipment or pulling work tools such as disks, compactors, or chopper wheels. Optional implement towing arrangements allow for quick setup of a hydraulically controlled towed scraper.
