Features

MAXIMIZE EFFICIENCY

  • Move more material at alower cost. Proven power train and Auto Shift give you both power to the ground and fuel efficiency.
  • Move up to 13 percent more material per pass with the largest standard blade in the size class (10.3 m³/13.5 yd3).
  • Keep working, even in high temperatures, with high ambient cooling capability.
  • Auto Shift automatically down shifts to the most efficient gear based on load for fuel savings.
  • Dual Tilt option optimizes blade pitch for up to 10 percent more productivity.
Note: Comparisons to previous D8R/D8T models

BUILT TO PERFORM

  • Cat C15 engine brings you more than a decade of proven reliability in a wide range of working conditions.
  • Harness more power to the ground with a planetary power shift transmission and high efficiency torque divider.
  • Rugged mainframe absorbs high impact shock loads and twisting forces.
  • Pivot shaft design allows the machine to better follow ground contours for maximum traction and operator comfort.
  • Elevated sprocket helps protect major components from harsh impacts and provides a modular design for convenient service.
  • Dedicated implement and steering pumps mean you can count on simultaneous blade response and steering performance.
  • Differential steering gives you exceptional turning, even with a full blade load.
Note: Comparisons to previous D8R/D8T models

HANDLE THE DESERT HEAT

  • High ambient capability makes the D8 well suited to extreme heat so you can work longer without shutting down.
  • Push in second gear to work faster without overheating.
  • Choose from a variety of factory options to support machine performance and service life in extremely sandy or abrasive conditions.
  • Turbine precleaner prevents particles from entering the engine system.
  • Solid-bottom engine enclosure doors help keep sand out forimproved cooling and reduced cleanout.
  • Specially coated fan and radiator core protection help resist abrasion. Reversing function is disabled on the hydraulic demand fan.
  • Sealed bottom guard and added seals help keep fine abrasive particles out of components. Access panels facilitate cleanout without removing bottom guard.
  • Replaceable wear plates offer longer blade life when working inabrasive conditions.

OPERATOR COMFORT AND CONTROL

  • Integrated Roll Over Protection Structure (ROPS) offers excellent all-around visibility to enhance productivity.
  • Quiet interior with improved pressurization helps keep dust out.
  • Standard air suspension seat is adjustable for operator comfort.
  • Optional electro-hydraulic controls reduce operator effort, improve precision and response, and enable Cat Grade technologies.
  • Pre-select forward/reverse gears with Bi-directional control to save effort and improve efficiency.
  • Implement Lock-Out prevents inadvertent operation of hydraulic attachments.
  • Liquid Crystal Display (LCD) places machine data, settings menus, grade control data and more conveniently in front of the operator.
  • LCD display is rear-camera-ready for added safety.

BECAUSE UPTIME COUNTS

  • Cat dozers are designed with features like wide engine panel access doors to minimize maintenance and repair time.
  • Exclusive new Cat hydraulic and power train oil filters offer extended service intervals to save you time and money.
  • Ecology drains help reduce spills during power train fluid changes.
  • Fast fuel system at ground level, with positive fuel shut-off, helps prevent fuel spillage/waste and speeds refueling for more uptime.
  • High-speed oil change attachment to help make servicing even faster.
  • Cab-mounted air conditioning condenser supports better system performance, improved engine cooling and serviceability.
  • Maximize your equipment investment with services like Customer Value Agreements, Custom Track Service and genuine Cat Parts.
  • Remanufactured parts offer a lower cost replacement option.
  • Certified Rebuild gives a “second life” for your machine.
