The Cat® D6T has earned a reputation for best-in-class versatility, productivity and resale value.
The Cat® D6T has earned a reputation for best-in-class versatility, productivity and resale value. Because it excels across a wide range of dozing tasks, customers choose the D6T for everything from dozing, ripping, scraper work and land clearing to finish grading, backfilling trenches, building oil/gas/wind farm pads and working landfills. The D6T offers many of the robust features found on larger tractors, with the reliability and low operating costs customers have come to expect from Cat Track-Type Tractors.
Comfort and ConvenienceLearn More
The D6T cab is designed for operator productivity, safety and comfort. An isolation-mounted, pressurized cab reduces noise and vibration. Large single-pane windows offer excellent visibility. The low rear window enables excellent rearward visibility and lets the operator see the ripper tip. The tapered hood, notched fuel tank, and narrow single-shank ripper carriage give the operator a clear line of sight to front and rear work areas.
The Cat Comfort Series seat is well padded and adjustable, with bolsters to help support the operator when working on slopes. Armrests are adjustable without tools, and heating/air conditioning vents evenly distribute airflow. The cab is pre-wired for a radio and equipped with two speakers, an antenna and a radio mount recessed in the headliner. A 10-amp, 12-volt power converter is also included to provide convenient supplemental power for cellular phones and computers.
Rugged design for maximum serviceLearn More
The foundation of every Cat dozer is a rugged frame built to absorb high impact shock loads and twisting forces. A reinforced saddle, welded front cross-member and steel castings on the main case add to the overall strength.
The pivot shaft is bolted to the mainframe and connects to the rear roller frames to allow independent oscillation. The pivot shaft distributes impact loads through the case. This design eliminates alignment problems and the need for diagonal braces on the roller frames.
The pinned equalizer bar gives the roller frames the ability to oscillate up and down to better match ground contours for maximum traction and operator comfort. Bolted end pins offer longer life and reduce downtime with improved serviceability and reliability. A remote lubrication point in the engine compartment provides easy access to lubricate the center pin of the equalizer bar as part of scheduled maintenance practices.
Power and SustainabilityLearn More
Every component of a Cat engine is carefully designed to maximize durability and reliability. Precise controls optimize power and fuel efficiency while reducing emissions.
The D6T features a Cat C9 engine with ACERT™ Technology. A series of Caterpillar engineered innovations provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions.
Modular design and advanced electronic diagnostics enhance the engine’s serviceability. An optional sand blast grid equips the machine for high airborne debris applications, and a demand fan saves fuel in low ambient temperature conditions.
The D6T cooling system is durable and efficient, utilizing aluminum bar plate construction on the radiator cores and Air To Air After Cooler (ATAAC). Aluminum bar plate provides durability and allows for high heat transfer and superior corrosion resistance. The radiator consists of twin unit cores that act together as one heat exchanger.
The Air To Air After Cooler is part of an advanced air management system that brings cool air to the engine. This increases life, reduces emissions, and helps maximize fuel efficiency.
The twin core is designed for easy service. Either half of the radiator can be removed by itself to reduce downtime and repair costs. A sight gauge makes daily service checks convenient.
The rugged aluminum bar plate construction helps protect against coolant leaks caused by tube punctures in abrasive applications. The unit core construction also reduces leak potential by eliminating core seals.
Powerful efficiencyLearn More
The powershift transmission and differential steering work in tandem with the Cat C9 engine to deliver outstanding power, productive performance and reliability.
Two Pump Hydraulic System
A dual hydraulic pump design provides dedicated hydraulic power to steering and implements for a 20 percent steering improvement. The slip pump design improves response in simultaneous steering/implement applications for greater maneuverability. The constant flow in steering circuit improves hydraulic cooling, increasing cooling capacity.
Multi Velocity Program (MVP)
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. MVP improves productivity in light applications (partial blade loads), where more speed flexibility is desired.
Differential Steering System
Differential steering maintains full power to both tracks, providing 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 insure ease of operation.
A single-stage torque divider sends 70 percent of engine torque through a converter and 30 percent through a direct drive shaft. This provides greater drive line efficiency and higher torque multiplication, delivering more power to the ground to optimize operator productivity.
Ergonomically designed for ease of operationLearn More
Steering and Transmission Control
Turns and directional changes are controlled with a single tiller handle. Buttons change the electronically controlled powershift transmission. Operators are able to work precisely in tight areas and around obstacles.
Dozer and Ripper Control Levers
The D6T features ergonomically designed dozer and ripper controls with low-effort, pilot-operated hydraulics. When equipped with a VPAT blade, the blade control allows simultaneous six-way control of the blade with a thumb rocker. The dozer control is equipped as an electro-hydraulic control when the AccuGrade™ Ready Option is installed.
Throttle Rocker Switch
The fingertip rocker switch activates high or low idle. A decelerator pedal gives the operator full control of engine speed when the rocker switch is in the high idle position. Engine speed can be set between high and low idle by simultaneously using the decelerator pedal and holding the Rabbit side of the throttle switch for three seconds.
Work Tool Lock-Out Switch
Work tool lock-out prevents inadvertent operation of hydraulic work tool attachments.
Operators can pre-select a forward and reverse speed setting for easy, efficient directional changes. Auto-kickdown allows the transmission to automatically downshift when significant load increases are detected.
Instrument Panel and Cat Monitoring System
The instrument panel, with easy-to-read gauges and warning lamps, keeps the operator aware of all system information. All gauges and readouts are easily visible in direct sunlight. The Cat Monitoring System has a dash mounted instrument cluster showing on-the-go operating information and insight into operation and maintenance needs.
Solutions to make work easier and more efficientLearn More
AccuGrade System for Track-Type Tractors
The AccuGrade System automates blade control for greater grading accuracy and more cost effective operation. Machine-mounted sensors calculate precise blade slope and elevation, which is used by sensors to automatically adjust the blade to maintain grade. Automated blade control improves efficiency and productivity by reaching grade faster and in fewer passes, reducing the need for traditional survey stakes or grade checkers.
AccuGrade Ready Option
AccuGrade systems and controls can be integrated from the factory, making system installation and setup quick and easy. Integration also provides greater wear protection and reliability.
Laser signals from a transmitter on the work site are picked up by a machine mounted receiver to provide a constant grade reference. The system calculates blade adjustments to achieve grade, makes automatic elevation adjustments and provides automatic blade control. The system also calculates cut/fill requirements for manual blade control.
Using global satellite-based positioning, AccuGrade GPS computes 3-dimensional positioning information on the machine, compares the position of the blade relative to the design plan, and delivers that information to the operator via an in-cab display.
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.

L-Shaped Push Arms
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 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 feature a strong box-section design, made from Cat DH-2™ steel with high tensile strength to stand up to the most severe applications. Heavy moldboard construction and hardened bolt-on cutting edges and end bits add strength and durability.
The Semi-Universal blade is built for tough applications where penetration and capacity are important. The blade wings are designed for superior load retention and penetration in tightly packed materials.
The S-blade provides good versatility. Because it has less blade capacity, it can handle heavier materials than a larger blade.
The angle blade is secured by outside-mounted push arms using a pinned connection that allows blade angling and tilting, left or right. Blade angle is changed manually and blade tilt is changed hydraulically.
Variable Pitch Angle Tilt (VPAT) Blade
The VPAT blade allows the operator to hydraulically adjust the blade lift, angle, and tilt simultaneously. The operator can also manually adjust blade pitch when the needs arise. This versatility gives the D6T the ability to take on a variety of applications such as finish grading, spreading material, slot-dozing, side casting, V-ditching, and trench backfilling.
Versatility and balanceLearn More
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.
A single lever control actuates both clutch and brake functions to help improve operator efficiency. See your Cat dealer for available winch options.
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.
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.
Engineered for performanceLearn More
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 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.
When uptime countsLearn More
