Experience the most intuitive nish grading tractor in the industry. The Cat® D3K2
Track-Type Tractor with Stable Blade delivers a smooth nish grade with less operator
effort. Stable Blade senses ground conditions and works with the operator to produce
the desired grade. The addition of the integrated AccuGrade™ grade control system
helps you get to target grade even faster, with fewer passes and less manpower.
Fromthe rst cut to nish grade, the D3K2 sets the standard.
Operator Station
Everyone can get comfortable in this cab.

Stable Blade Control
New Stable Blade control makes operating the machine easy
forbothnew and experienced operators.
• Stable Blade complements operator input for smooth nish
gradingresults
• Handle ts to hand to allow for more precise control
and reduce operator fatigue
• Thumb roller for low effort blade angle control
• Blade shake feature for easy removal of material
All Day Comfort
The spacious, comfortable cab helps keep you relaxed
and productive throughout the day.
• Quiet environment – 78 dB(A) – ANSI/SAE J1166 OCT98

Hydrostatic Transmission
Responsive to changing loads.
Traction Control
Increase your productivity with the new Traction Control
feature:
• Reduces track slippage
• Activated with a button on the transmission control
• Reduces undercarriage wear
• Improves fuel economy
Performance
Quick response to varying loads for shorter cycle times
and less operator fatigue.
Maneuverability
• Intuitive control helps you work in tight areas
• Power turn feature provides power to both tracks while
working in conned areas
• Counter-rotation provides quick steering corrections
during side loading applications
Cat C4.4 Engine
The C4.4 engine responds quickly to changing
loads. Eco mode throttle setting can deliver up
to 25% improved fuel economy. 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
• Long life diesel particulate lter (no service
required for 8,000 hours)
6
Engine
Increased horsepower, improved fuel economy.
Undercarriage
Solutions to lower your costs per hour.
Choice of Undercarriage Congurations to Meet Your Application
Track frames are available in extra long (XL) or low ground pressure (LGP) congurations:
• XL undercarriage for most applications where otation and side stability are not extreme
• LGP undercarriage for soft underfoot conditions where additional otation is required
• 762 mm (30 in) LGP undercarriage available for extremely soft underfoot conditions
Track Selections
Caterpillar offers a choice of two undercarriages – Sealed and Lubricated Track (SALT) and SystemOne™.
Matching the correct undercarriage to the application and soil conditions will deliver the lowest costs per hour.
• Sealed and Lubricated Track (SALT) Undercarriage
– For applications where the track is not bushing limited
– May require pin and bushing turn
• SystemOne™ Undercarriage
– For applications where track is bushing limited
– Bushing rotates continuously
– Does not require bushing turn
– Designed to maximize the life of all undercarriage components
7
AccuGrade™ Systems
Grade with increased accuracy.
Improve Your Efciency with AccuGrade
AccuGrade is a fast machine grade control system which 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 Laser, GNSS or Universal Total Station solutions:
• AccuGrade Laser – for two dimensional at type work
• AccuGrade GNSS – for three dimensional cut to contour work
• Universal Total Station – for ne and nish grade applications

the blade pitch to meet various operating conditions
without ever leaving the cab.
• Pitch the blade forward for increased penetration
• Lay the blade back for maximum carrying capacity
• Change the pitch from inside the cab
• Optimize blade pitch for application
• Improves productivity
VPAT Blade
The VPAT blade is specically designed for nish grading,
backlling ditches, cutting V ditches, windrowing, ll
spreading, medium land clearing and heavy dozing.
Built for rugged strength and durability this 6-way blade
allows for maximum angle, tilt and pitch.
Hydrostatic Winch
The Cat hydrostatic winch features:
• Excellent line pull at any speed
