*VPAT foldable blades have the same capacity and width as the XL/LGP VPAT blades.
The new D6K2 dozer is smarter and more efficient than ever. It comes equipped with standard Grade technologies like Slope Assist to make it easier for even less experienced operators to get more quality work done in less time. But intelligence is only part of the package – Eco Modes and a new power train deliver up to 17 percent more fuel efficiency, while providing superior maneuverability, faster steering response and greater capability to utilize full blade loads. This dozer also retains its optimal balance and undercarriage design for outstanding performance in finish grading applications. The D6K2 meets Tier 4 Final/Stage IV/Korea Tier 4 emission standards.
Benefits & Features
Power and Efficiency
Designed for performance
Powerful Drive Train
A Cat C4.4 ACERT engine with twin turbochargers is combined with a new hydrostatic transmission to give you improved fuel efficiency and the most power-dense drive train in its size class. The hystat transmission offers superior maneuverability, faster steering response and greater capability to utilize full blade loads.
Eco Modes optimize engine speed, while maintaining ground speed, saving up to 17 percent fuel in lighter blade load applications like finish grading.
Efficiency features reduce engine speed when idling, or shut the machine down after a specified time, to further save fuel and meet idling regulations. Engine Idle Shutdown shuts down engine after pre-set time to reduce idling and help save fuel.
New automatic traction control is standard and automatically reduces track slip in poor underfoot conditions, improving productivity and finish surface quality.
Updated cooling package allows more air flow, reducing fan speed for greater efficiency. Hydraulic demand fan automatically reduces fan speed in cooler conditions to help save fuel. An optional hydraulic reversing fan offers automatic or manual modes for changing direction to blow debris out of the radiator cores.
Comfort and Productivity
Spacious, quiet cab offers all-day comfort with wide door openings and an air suspension seat. Ergonomic, seat-mounted joystick controls isolate vibration. Excellent visibility to the blade, curbs and tight spaces help you work more precisely.
The new Liquid Crystal Display (LCD) is easy to read, enables Slope Assist, and is rear-camera ready so no additional monitor is needed.
Implement and Steering Controls
Single joystick for speed, direction and steering; includes thumb wheel for speed adjustment and traction control.
Dozer/implement controls give you 6-way control of the VPAT blade and allows power pitch adjustment. Blade shake feature helps shed sticky material.
Emissions technology that is transparent – no action required from the operator, no stopping for regeneration.
Diesel Exhaust Fluid (DEF) use typically about 2.5 percent of fuel consumption – provides excellent overall fluid efficiency.
Diesel Particulate Filter designed for the life of the engine – no need to clean out.
Pump automatically purges DEF lines to help prevent freezing.
When refilling Diesel Exhaust Fluid, a tone will sound (with key on) when tank is nearly full.

GRADE for Dozers
Cat Connect GRADE technologies help you hit target grade faster and more accurately. Finish jobs in fewer passes, and with less operator effort, saving you time and helping you increase profit.
Cat GRADE with Slope Assist (Standard) helps operators more easily achieve the required main-fall and slope orientation of the blade by automatically maintaining pre-established blade angles for the grade. The system saves time, increases finish quality and reduces operator input. Experienced operators can work more productively and less experienced operators can achieve better quality results more quickly.
Cat Slope Indicate (Standard) displays machine cross-slope and fore/aft orientation on the primary monitor, helping operators work more accurately on slopes.
Cat Stable Blade (Standard) complements the operator’s blade-control input for attaining finish grades quicker with less effort.
Cat GRADE with 3D (Optional – available early 2017) is a factory integrated grade control system that enables operators to improve grading efficiency, accuracy, and productivity in both production dozing and fine-grading applications. The integrated design positions antennas on the cab roof, eliminating conventional blade-mounted masts and related cables. The AccuGrade Ready Option (ARO) is part of the package for added versatility, and AutoCarry™ is included to further boost productivity.
Cat AccuGrade (Optional) is a dealer-installed aftermarket grade-control system that provides increased grading versatility and the ability to scale capacity to changing needs, providing a choice of lasers for 2D flat-plane and slope work, Global Navigation Satellite System (GNSS) control for complex 3D cuts and contours, and/or systems using a Universal Total Station (UTS) for fine and finish grading.
AccuGrade Ready Option (ARO) (Optional) allows you to easily install or upgrade to AccuGrade 2D and 3D grade-control systems to add versatility and resale value to your machine.
