Power Train

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

Unsurpassed Maneuverability

Fuel Economy

Eco Modes

Eco Modes achieve signicant 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

6

Undercarriage

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  nish grading
performance. You can grade faster, while still producing a top quality nish grade at the  rst pass.

Choice of Undercarriage Congurations to Meet Your Application

Track frames are available in extra long (XL) or low ground pressure (LGP) con gurations:

• XL undercarriage for most applications where otation and side stability are not extreme

• LGP undercarriage for soft underfoot conditions where additional otation 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

7

Work Tools

Move more with productive and durable blades

New Bulldozer and Wider Blade Design

• Both XL and LGP blades are now wider; this improves
nish 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 nish grading, spreading material or back lling.

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.

8

Integrated Technologies

Get to grade faster with fewer passes than ever before

AccuGrade

This dealer installed machine control and guidance system enables operators to cut and ll to grade with increased accuracy,
minimizing the need for traditional stakes and grade checkers. Caterpillar offers a choice of:

• AccuGrade Laser – for two dimensional at type of work

• AccuGrade Global Navigation Satellite System – for three dimensional cut to contour work

• Universal Total Station – for ne and nish 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:

Engine and Emissions Technology

Improved fuel economy

Low Temperature Regeneration System

The engine meets U.S. EPA Tier 4 Interim, EU Stage IIIB and Japan MLIT Step 4
emission standards using a passive regeneration solution:

• Simple, no operator interaction required

• Efcient, no work interruption, even in case of extended idling time

• Reliable, long life diesel particulate lter (no service required for over
10,000hours)

Fuel Consumption Efciency

Automatic Engine Speed Control (AESC) – reduces engine speed when the machine is

not under load for more than ve seconds, which can help reduce fuel consumption
signicantly depending on the application.

Engine Idle Shutdown Timer – This option (when activated by the operator) shuts
down the engine after the machine has been idling for a pre-set period of time.
