Note (3) All non road Tier 4 Interim and Final, Stage IIIB and IV, Japan 2014 (Tier 4 Final) and Korea Tier 4 Final diesel engines are required to use only Ultra Low Sulfur Diesel (ULSD) fuels containing 15 ppm EPA/10 ppm EU (mg/kg) sulfur or less. Biodiesel blends up to B20 (20% blend by volume) are acceptable when blended with 15 ppm (mg/kg) sulfur or less ULSD. B20 should meet ASTM D7467 specification (biodiesel blend stock should meet Cat biodiesel spec, ASTM D6751 or EN 14214). Cat DEO-ULS™ or oils that meet the Cat ECF-3, API CJ-4, and ACEA E9 specification are required. Consult your OMM for further machine specific fuel recommendations.

NEW NAME, SAME TOP PERFORMANCE

  • 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.

PERFORMANCE AND PRODUCTIVITY

  • 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.

TECHNOLOGY THAT GETS WORK DONE

  • 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.

ACHIEVE THE BEST GRADES

  • 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.

EASY TO OPERATE

  • 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.
  • Automatic Traction Control reduces track slip in poor underfoot conditions.
  • Standard rear vision camera provides enhanced visibility.
  • Easy to transport without blade removal when equipped with the folding blade option.

BECAUSE UPTIME COUNTS

  • Grouped maintenance and diagnostic points, as well as ground level service and Diesel Exhaust Fluid fill access.
  • Track roller frame designed for easy cleanout.
  • Optional bracket mounts to rear of machine to keep a shovel handy.
  • Diesel Particulate Filter designed for the life of the engine – no need to clean out.
