SPECS SUMMARY

Engine ModelCat C4.4
Power - Net130 HP (97 kW)
Operating Weight29258 lb (13271 kg)
EmissionsU.S. EPA Tier 4 Final/EU Stage IV/Japan 2014/Korea Tier 4 Final
The D4 dozer (formerly D6K2) is smart and efficient. It comes equipped with GRADE technologies like Slope Assist and GRADE with 3D to make it easier for even less experienced operators to get more quality work done in less time. But intelligence is only part of the package – Eco Modes and a new power train deliver up to 17 percent more fuel efficiency, while providing superior maneuverability, faster steering response and greater capability to utilize full blade loads. This dozer also retains its optimal balance and undercarriage design for outstanding performance in finish grading applications.

Benefits and Features

  • The D6K2 is now the D4, with the same weight, horsepower and balanced design that has made this dozer a favorite for top grading performance.
  • The update from D6K2 to D4 is part of an effort to make all Cat dozer model names simpler.
  • Over the next couple of years, the Cat dozer range will be renamed from smallest to largest – D1 to D11 – with one model per size class and no more letter modifiers like “N,” “K,” “T.”
  • While the number may be different, the D4 delivers all the advantages of the D6K2.

  • Cat C4.4 engine with twin turbochargers is combined with a hydrostatic transmission for outstanding fuel efficiency and the most power-dense drive train in its size class.
  • Superior maneuverability, faster steering response, greater capability to utilize full blade loads.
  • Eco Modes optimize engine speed, while maintaining ground speed, saving up to 17 percent fuel compared to the previous model in lighter blade load applications like finish grading.
  • Optimized undercarriage – eight (8) bottom rollers and two (2) carrier rollers for smoother ride and excellent finish grading performance.
  • Wide blade helps get more work done in fewer passes.
  • Variable Pitch Angle Tilt (VPAT) blade for more versatility, simpler adjustment.

  • Hit target grade faster and more accurately with Cat GRADE technologies. Finish jobs in fewer passes, and with less operator effort, saving you time and helping to increase your profit.
  • Cat GRADE with Slope Assist™ automatically maintains pre-established blade position without a GPS signal.
  • Updated Cat GRADE with 3D offers greater speed, accuracy and flexibility. Factory-integrated system eliminates position sensing cylinders. Antennas integrated into the cab roof for better protection.
  • More intuitive 10-inch (254 mm) touchscreen grade control display is easier to use.
  • AutoCarry™ automates blade lift to maximize blade load, improve load consistency, reduce track slip.
  • Cat Stable Blade works with electro-hydraulic controls to complement the operator’s blade-control input to get better finish grades faster and with less effort.
  • Standard Slope Indicate displays machine cross-slope and fore/aft orientation right on the main display.
  • Factory Attachment Ready Option (ARO) simplifies installation of all brands of grade control system.
  • Product Link™ collects machine data that can be viewed online through web and mobile applications.
  • Access information anytime, anywhere with VisionLink® – and use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve security on your job site.

  • Designed from the ground up to give you a smooth ride so you can make the most of top grading speeds.
  • Eight bottom rollers and two carrier rollers optimize the undercarriage to give you smoother finish grades.
  • Rugged Variable Pitch Angle Tilt (VPAT) blade allows you to hydraulically adjust lift, angle and tilt for precise results.
  • Technologies like Slope Assist and Stable Blade are integrated right into the dozer to help even less experienced operators achieve a quality grade more quickly, and with fewer inputs.

  • Fast response with intuitive, precise electro-hydraulic controls. Adjust sensitivity to fine, medium or coarse.
  • Liquid Crystal Display (LCD) is easy to read – includes your Slope Assist and rear camera displays (if equipped).
  • Power Pitch option lets you easily adjust blade to optimum pitch for your application using buttons on the right hand control.
