Fuel Economy
Eco Modes


Fuel Economy

Eco Modes achieve significant fuel consumption reduction by allowing the engine to run at lower speed whenever possible, and rapidly increasing speed when power is needed. Designed to save fuel in light or medium duty applications, the extremely fast engine response allows these modes to be used even in power demanding applications and eliminates the need to constantly shift into and out of Eco Modes.
  • Operators can either select the “Reverse only” or “Forward and Reverse” mode
  • Can help save from 5 percent up to 22 percent of fuel depending on the application

Undercarriage
Solutions to lower your costs per hour


Undercarriage

Updated Undercarriage Design
The new undercarriage design improves durability and increases stability to allow smoother ride and excellent finish grading performance. You can grade faster, while still producing a top quality finish grade at the first pass.

Choice of Undercarriage Configurations to Meet Your Application
Track frames are available in extra long (XL) or low ground pressure (LGP) configurations:
  • XL undercarriage for most applications where flotation and side stability are not extreme
  • LGP undercarriage for soft underfoot conditions where additional flotation is required

Track Selection
Caterpillar offers a choice of two undercarriages - Sealed and Lubricated Track (S<) and SystemOne™. Matching the correct undercarriage to the application and soil conditions will deliver the lowest costs per hour.
  • Sealed and Lubricated Track (S<) Undercarriage - For aggressive impact applications, with the necessary wear material for long life - Designed to ease disassembly for bushing turn service to maximize wear life
  • SystemOne Undercarriage
- For moderate to high abrasion applications - For reduced maintenance costs and increased life of all undercarriage components - Innovative rotating bushing design that eliminates the need for bushing turns

Work Tools
Move more with productive and durable blades


Work Tools

New Bulldozer and Wider Blade Design
  • Both XL and LGP blades are now wider; this improves finish grading productivity by covering more ground at each pass
  • Strong design allows Cat blades to stand up to the most severe applications
  • Large spherical linkage bearing for easier blade removal and designed for the life of the machine

New Variable Pitch Angle Tilt (VPAT) Blade
The versatility of the VPAT Blade gives the D6K2 the ability to take on a variety of applications and material conditions, such as finish grading, spreading material or backfilling. This blade allows the operator to adjust the blade lift, angle and tilt simultaneously. The blade pitch adjustment is made easier, which can help increase your productivity.

New Foldable Blade Option
Designed to facilitate transportation without blade removal, foldable blades reduce the overall shipping width. The blade can be easily folded without the need for tools.

Integrated Technologies
Get to grade faster with fewer passes than ever before


Integrated Technologies

AccuGrade
This dealer installed machine control and guidance system enables operators to cut and fill to grade with increased accuracy, minimizing the need for traditional stakes and grade checkers. Caterpillar offers a choice of:
  • AccuGrade Laser - for two dimensional flat type of work
  • AccuGrade Global Navigation Satellite System - for three dimensional cut to contour work
  • Universal Total Station - for fine and finish grade applications
These technologies provide precise elevation information on an in-cab display to achieve accurate blade positioning and improve productivity by as much as 50 percent over conventional methods.

AccuGrade Ready Option (ARO)
This option provides the pre-assembly that is required to make the AccuGrade installation quick and easy.

New Larger Displays
Easy to read, large displays let you focus on your work:
  • CB450 Larger Display - larger 109 mm (4.3 in) color display, USB data port
  • CB460 GNSS Display - larger 178 mm (7 in) color display, USB data port

Rear Attachments and Options
