Mainframe Strength – Built to Last
Helping you get more done with maximum availability, the D9T’s durable design makes repair and maintenance easy. Customers can rebuild these tractors several times using the same frame with only minor repairs. With unparalleled support from Cat dealers it is not unusual for a Cat large dozer to log more than 100,000 hours.
Tag-Link blade mounting brings the blade closer to the machine for excellent maneuverability, machine balance and blade penetration. This design also eliminates the need for diagonal bracing by transferring side loads to the mainframe, instead of the dozer push arms.
Equalizer Bar End Pins
Proper grease lubrication on working surfaces can significantly extend component life and help lower maintenance cost.
Power and reliability to help you move more.Learn More
Performing at full-rated net power of 306 kW (410 hp), the large displacement and high torque rise allow the D9T to rip through tough material. Matched to the high-efficiency torque converter and electronically controlled power shift transmission, it will provide years of reliable service.
ADEM™ A4 Engine Controller
Manages fuel delivery for optimal performance per liter (gallon) of fuel used. Provides flexible fuel mapping, allowing the engine to respond quickly to application needs. Tracks conditions and keeps engine operating at peak efficiency.
Air-to-Air Aftercooling and Airflow
Air-to-air aftercooling keeps air intake temperatures down and, in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. Significant improvements in air flow are generated by a water-cooled turbocharger, unique cross-flow head and single overhead cam.
Fuel Heater (optional)
Uses the temperature of the engine coolant to warm the cold fuel coming directly from the tank. The fuel heater allows an easier transition to winter blended fuels during season changes.
High Altitude Arrangement (optional)
The attachment provides an updated turbo and control software that allows full tractor performance up to 4420 m (14,500 ft) altitude.
Superior cooling keeps you moving in the most demanding work conditions.Learn More
Aluminum Bar Plate Radiator – 6 Fins Per Inch (fpi)
Cooling system uses a radiator built with rugged, highly efficient aluminum bar plate cores. The aluminum bar plate construction aids durability and allows for higher heat transfer and superior corrosion resistance.
Hydraulic Oil to Air Cooler
Helping to save on repair and maintenance costs, the oil to air hydraulic cooler helps extend component life by reducing hydraulic oil temperatures.
Hydraulically Variable, Demand Fan
Customers experience increased production and fuel economy as well as reductions in fan noise and engine over cooling with the hydraulically variable demand fan. The demand fan changes speed to match ambient conditions. In cooler environments, the fan turns at a slower speed; consuming only the power required to cool the tractor system, providing more power to the tracks to help you lower your cost per unit of material moved.
Power and control to efficiently move your material.Learn More
The D9T power train design optimizes performance and the ease of operation helps customers get more done for the lowest cost per unit.
A high efficiency torque converter with fixed stator provides high torque multiplication while shielding the drive train from sudden torque shocks and vibration.
Enhanced Autoshift (EAS)
A standard feature for the D9T is EAS. EAS improves fuel efficiency and productivity by automatically selecting the optimal gear and engine speed combination based upon power train load and desired ground speed. This feature functions similar to an automatic transmission.
This convenience feature helps reduce operator work load during operation. Bi-directional shift allows the operator, by just making a directional change, to automatically select the desired forward and reverse gears or the desired forward and reverse speeds when EAS is activated.
This feature adds value by enhancing safety and productivity during the dozing cycle. When not in EAS mode, auto downshift can be used to automatically downshift the transmission when significant load increases are detected, but this feature will not automatically up-shift when load is reduced. Auto downshift provides optimal performance with minimal operator effort. The operator may override these automatic shift features at any time.
High Availability Is Key
Major power train components are modular in design, so being able to quickly remove and reinstall a new pre-tested component gives you the ability to keep the dozer up and running and producing.
Planetary Powershift Transmission
Power Turn with Differential Steering
With differential steering, large blade loads can be smoothly maneuvered throughout a turn.
Designed for optimized machine balance and best performance at your site.Learn More
The elevated sprocket and fully suspended undercarriage work together, increasing traction while creating a smoother ride for your operators. The elevated sprocket design transfers implement shock loads to the mainframe, so final drives, axles and steering components are isolated from harsh impacts. These benefits translate into higher production and longer component life.
Provide flexibility to match the machine to your job.Learn More
All blades feature a strong box-section design that resists twisting and cracking. Blades are made of high tensile strength steel that stands up to the most demanding applications.
CapSure™ Hammerless Ripper Tip and Shank Protector Retention System
The tip and shank protector are easily installed with a 180 degree turn of a ¾ inch ratchet. This simple installation means no hammering and therefore improved safety. It also means quicker change outs and less downtime.
Provide proper tractor balance to maximize dozing production. Recommended if dozer is not equipped with any other rear attachment.
Designed for your comfort, convenience, and productivity.Learn More
The D9T cab is designed and equipped for operator productivity, safety and comfort. The standard isolation-mounted cab reduces noise and vibration.
