Productivity

        
  • Added productivity and up to 10 percent fuel savings, delivering up to 18 percent better dozing efficiency.(1)
    •     
  • 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.(1) 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.
(1) Compared to previous model D8R.

Performance

        
  • Cat C15 ACERT™ engine delivers more horsepower,(1) with more than a decade of proven reliability in a wide range of working conditions.
