Hydraulic Air to Oil Cooler
The new air to hydraulic oil cooler reduces hydraulic oil temperatures improving component life. The core is built using the same rugged aluminum bar plate design as the jacket water cooler. It is designed in-line with the water cores to minimize debris plugging in all applications.
Hydraulically Variable, Demand Fan
Provides engine cooling capability that is matched to the ambient conditions. In cooler conditions, the fan turns at a slower speed, reducing power demands. This reduces fuel consumption in lower load factor operations. Low speed fan operation also reduces both operator and spectator sound levels.
Comfort and convenienceLearn More
The D9T cab is designed and equipped for operator productivity, safety and comfort. The standard isolation-mounted cab reduces noise and vibration. Overall operator sound levels have been reduced by 2 dB(A). Large windows, tapered hood, and notched fuel tank provide excellent visibility to all sides of the machine and around the job site.
The D9T comes with an updated in-dash display with new features. An improved Advisor Monitoring System tracks machine operating conditions in real time. Dimmable lights allow the operator to choose between night and day backlight settings, through Advisor, to adjust the brightness of all switches and the keypad in the cab.
Operators will enjoy comfort features like standard Cat Comfort Series Seat, adjustable arm rests and automatic climate control. The climate control system automatically adjusts heater and air conditioning controls to maintain a consistent cab temperature throughout the day. Both heater and air conditioner deliver filtered, pressurized, temperature controlled air to the operator and/or windows. The system performs 5 functions: heating, cooling, defrosting, pressurizing and defogging.
Additional cab features include:
Ergonomically designed for ease of operationLearn More
Dozer Control Lever
A low-effort electronic dozer control handle gives the operator control of all dozer functions with one hand. Fore/aft movement of the control handle lowers and raises the blade. Left/right movement directionally tilts the blade. Blade response and blade float can be set/adjusted using the Advisor System.
The thumb lever at the top of the handle and trigger switch controls blade pitch fore and aft when equipped with dual tilt. Dual tilt also provides automated blade assist control capability.
Electronic Ripper Control
A rigidly mounted handgrip provides firm support for the operator even when ripping in the roughest terrain. The low effort thumb lever controls raising and lowering. The finger lever controls shank-in and shank-out positioning.
The monitoring system collects machine data and provides real-time feedback on machine productivity to optimize performance. Data summaries can be sent to off-board tools for site managers to review.
Terrain for Grading (optional)
Provides high precision management of dozing and grading applications for enhanced safety, productivity and efficiency. The system enables an electronic site plan to be sent to the machine from the office in real-time, directing the operator where to cut and fill.
Automatic Ripper Control (optional)
A new feature that reduces operator fatigue and decreases wear and tear on the machine. This is done by monitoring the tractor ground speed with the new cab mounted Global Navigation Satellite System (GNSS) to automatically adjust engine speed and ripper depth to minimize track slip.
Enhances operators productivity by coninuously monitoring ground speed and automatically adjusts blade load.
Cat Grade Control (optional)
Integrates traditional machine control and guidance with machine hardware and software to help improve productivity, usability, reliability and value.
Cat Grade Control software is enhanced to not only automatically guide the blade to the desired design contours, but also integrated with Autocarry to sense and automatically control the load of the blade for improved performance and efficient blade loading in high production dozing applications.

Suspended Undercarriage Design
Absorbs impact loads, to reduce the shock loads transferred to the undercarriage, by up to 50%.
Bogie suspension conforms closely to the ground providing up to 15 percent more ground contact, especially in uneven terrain. Higher traction means less slippage, better balance, and a smoother ride.
Integrated Carrier Roller Mount
The carrier roller mount is cast into the track roller frame making it easier to add the optional carrier roller in the field, if conditions require it.
Rollers and Idlers
Feature symmetric Duo-Cone™ seals for long sealing life to prevent oil loss and dirt entry. Toric rings maintain performance over a wide range of temperatures.
Roller frames are tubular to resist bending and twisting, with added reinforcement.
Positive Pin Retention (PPR) Sealed and Lubricated Track
Designed for high-impact and high load applications, the Caterpillar design locks the link to the pin.
Made exclusively of Cat Tough Steel™ for longer wear life and precision machined for fit.
