PERFORMANCE & EFFICIENCY

The torque converter with stator clutch automatically frees up the stator when torque multiplication is not required under low load, resulting in higher drivetrain efficiency for reduced fuel consumption.
Bogie suspension allows the track to conform to ground conditions, delivering higher traction and less slippage.
Differential steering enables large loads, with fast and smooth maneuvering.

OPERATOR COMFORT

The cab is unparalleled, with enhanced ergonomics, a fully adjustable air suspension seat and automatic temperature control.
The suspended undercarriage absorbs impact and reduces shock loads transferred to the undercarriage by up to 50% for a smoother, more comfortable ride.
Low-effort electronic steering, ripper and dozer controls are easily accessible and provide sure, precise maneuvering.

SAFETY

The operator station offers an exceptional viewing area, with a tapered hood, notched fuel tank, and narrow ripper carriage to give the operator a clear line of sight to front and rear work areas.
The optional 360 Vision camera system and in-cab display further enhance visibility.
An optional powered ladder improves access and egress.
Ground-level access, forward-hinging cab door, retention pins on bottom guard and removed lift cylinder grease points provide a greater level of safety for service personnel.

PRODUCTIVITY

Differential steering provides a tight turning radius and maintains a high ground speed while turning.
The planetary powershift transmission controls permit smooth speed and direction changes with Advanced Productivity Electronic Control System (APECS).
The in-cab touchscreen Information Display is larger, faster, and more powerful with increased memory and intuitive menu structure.
The optional Work Monitor screen collects machine data and provides real-time feedback on machine performance to optimize productivity.
The Dual Tilt option allows the operator to optimize blade pitch angle, improving load control and making it possible to carry material instead of only pushing it.

VERSATILITY

The D9 is versatile enough for a variety of applications and is ideal for use in heavy construction, quarries, landfills, stockpiles, forestry and mine sites.
The powerful Cat C18 Engine is available in U.S. EPA Tier 2, U.S. EPA Tier 3, U.S. EPA Tier 4 Final and EU Stage V configurations.
The fully suspended undercarriage provides more ground contact, leading to less slippage and more overall productivity in all applications.
Continuous power to both tracks provides smooth turning control and excellent maneuverability in every application, all while keeping ground speed high.

TECHNOLOGY & INNOVATION

Product Link™ Elite enables the remote transmission of information about the location, operation and condition of your equipment.
Automated Blade Assist (ABA) (optional) increases efficiency while reducing operator workload, making use of preset blade pitch positions for the load, carry and spread portions of the cycle.
AutoCarry™ (optional) automates blade lift to maintain desired blade load, improve load consistency and reduce track slip.
Automatic Ripper Control (optional) automatically controls ripper height to limit track slip, reducing operator fatigue.
Optional Cat MineStar™ Command for dozing offers multiple levels of remote-control operation.

SERVICEABILITY

Features such as integrated AutoLube System, fewer greasing points, longer filter change intervals, easy component removal and continuous fluid level monitoring contribute to up to 4% maintenance and repair savings.
Grouped maintenance points minimize movement around the machine, and ground-level access enables easier service for fluids and key electrical controls.
Remote flash sends an alert from your Cat dealer, prompting you to update the software on your machine. Updates can be deployed on site, without having to wait for a dealer technician to arrive.

BLADES & ATTACHMENTS

The perfect match for the D9, Cat blades are aggressive in tough materials and offer superior loadability.
Cat blades have the ability to resist torsional bending and distortion and offer increased wear resistance without sacrificing machine balance or performance.
Specialty attachments include single-shank ripper and multi-shank ripper

BUILT TO GO THE DISTANCE

Frame is built to absorb high-impact shock loads and twisting forces encountered during severe dozing and ripping applications.
Powertrain and main components are built to be rebuilt for a cost-effective second life of like-new performance at a fraction-of-new price.
The DuraLink™ undercarriage offers 20 to 40% longer life and delivers 8,000-hour seal life with new, heavy-duty extended-life (HDXL) undercarriage.

SUSTAINABILITY

The D9 is designed to use less fuel, which reduces engine emissions.
The Tier 4 Final engine reduces NOx and particulate matter, plus the engine is compatible with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels.
Features like extended life filters and longer maintenance intervals decrease the amount of waste contributed to the environment.
By rebuilding machines and components, the Cat Rebuild and Cat Reman programs preserve raw materials, conserve energy and reduce emissions. In addition, retrofits and upgrades for older machines incorporate efficiency improvements and emission reductions, and keep them in production longer to conserve energy and minimize the need for raw materials.
Increased commonality of systems and components, plus a reduction in unique part numbers, reduces waste and lowers owning and operating costs.
