  • Added productivity and up to 10 percent fuel savings, delivering up to 18 percent better dozing efficiency than previous model D8T.
  • Move up to 13 percent more material per pass with the largest standard blade in the size class (10.3 m³).
  • Keep working, even in high temperatures, with increased cooling capability.
  • Push in second gear for more dozing productivity.
  • Save fuel with a hydraulic demand fan that reduces speed in cooler conditions. Optional reversing capability for high debris conditions.
  • Auto Shift automatically down shifts to the most efficient gear based on load, adding to overall fuel savings.


  • Cat C15 engine delivers more horsepower, with more than a decade of proven reliability in a wide range of working conditions.
  • More efficient power train, hydraulic fan and new radiator increase ambient capability up to 23 percent.
  • Purpose-built Desert Arrangement includes added cooling performance and more protection for working in extremely sandy or abrasive conditions.
  • Optional cab-mounted air conditioning condenser supports better system performance, improved engine cooling and serviceability.
  • Easier maintenance access with wider engine panel doors and optional bottom guard access panels.

    Note: Comparisons to previous model D8T

  • Cab-mounted air conditioning condenser supports better system performance, improved engine cooling and serviceability.
  • 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.
  • When you need repairs, Cat dealers and our unmatched Caterpillar distribution network excel at getting you the right parts you need quickly.
  • Maximize your equipment investment with services like Customer Support Agreements, preventive maintenance programs and guaranteed maintenance contracts.
  • Remanufactured parts offer a lower cost replacement option.
  • Certified Rebuild gives a “second life” for your machine.


  • Equip your dozer for the demands of desert applications with features ideally suited to support machine performance and service life in extremely sandy or abrasive conditions, choose from these options:
  • Precleaner Turbine air intake system prevents nearly all of the heavier-than-air particles from entering the system, which results in longer air filter life, more efficient engine performance and decreased maintenance expenses.
  • Engine enclosure doors are solid at the bottom to help reduce the amount of sand carried into the engine compartment for improved cooling and reduced cleanout time.
  • 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.
  • Bottom guard access panels facilitate cleanout without removing bottom guard.
  • Wear plates can be replaced to give you longer blade life when working in abrasive conditions.
  • Cab-mounted air conditioning condenser recommended to help improve system performance and aid serviceability.
