Benefits & Features
Thinking generations ahead
Sustainable development for Caterpillar means leveraging technology to increase your efficiency and productivity with less impact on the environment and assisting our customers do the same. Caterpillar is providing products, services and solutions that use resources more efficiently - from reducing emissions to remanufacturing.
Meets U.S. EPA Tier 4 Interim, EU Stage IIIB and Japan MLIT Step 4 emission standards.
Fuel efficient engine and features such as the Eco Modes help reduce your overall fuel consumption. Decreases in fuel consumption result in a decrease in combustion of carbon.
Technologies like AccuGrade and Product Link™ help improve overall efficiency, save fuel and fluids as well as wear and tear on equipment.
Biodiesels (20% maximum, mixed with Ultra Low Sulfur Diesel Fuel) and biodegradable hydraulic oil can be used without reducing the life of the system. Always refer to your Operation and Maintenance Manual for proper usage of fluids.
Major components are built to be rebuilt, eliminating waste and saving customers money.

…assists you in finish grading applications.
Both new and experienced operators will find operating the machine easy with our new Stable Blade Control. Stable Blade Control senses ground conditions to complement operator input for smooth finish grading results with less operator effort. This system reacts faster than humanly possible.
Smooth and responsive to changing loads
Performance: Hydrostatic Transmission
Engine speed is automatically maintained to match the power requirements of the application. It also offers independent power and control of each track, for fast acceleration and on-the-go direction changes.
Quick response to varying loads for shorter cycle times
Traction control allows better traction when working in poor underfoot conditions
Intuitive controls help you work in tight areas
Power turn feature provides power to both tracks while working in confined area
Counter-rotation provides quick steering corrections during side loading applications
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
Solutions to lower your costs per hour
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
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
- 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
Move more with productive and durable blades
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.
Get to grade faster with fewer passes than ever before
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
Increase your versatility
The aggressive parallelogram ripper lets you do more productive ripper work. The parallel linkage design provides better penetration and maneuverability in tight working areas.
The winch features excellent line pull at any speed, infinitely variable drum speed, lower operator effort and unmatched load control.
Dual Control Package
This option makes attachment installation easy for machines that will be used for both ripper and winch applications.
The drawbar is useful for retrieving other equipment or pulling work tools such as discs or compactors.
