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.
