Cat Medium Dozers D6K2
Product Feature
Performance
Cat C4.4 engine with twin turbochargers is combined with a hydrostatic transmission for outstanding fuel efficiency and the most power-dense drive train in its size class.
Superior maneuverability, faster steering response, greater capability to utilize full blade loads.
Eco Modes optimize engine speed, while maintaining ground speed, saving up to 17 percent fuel compared to the previous model in lighter blade load applications like finish grading.
Optimized undercarriage – eight (8) bottom rollers and two (2) carrier rollers for smoother ride and excellent finish grading performance.
Wide blade helps get more work done in fewer passes.
Variable Pitch Angle Tilt (VPAT) blade for more versatility, simpler adjustment.
Cat Technology
Hit target grade faster and more accurately with Cat GRADE technologies – Finish jobs in fewer passes, and with less operator effort, saving you time and helping to increase your profit.
Cat GRADE with Slope Assist™ automatically maintains preestablished blade position without a GPS signal.
Updated Cat GRADE with 3D offers greater speed, accuracy and flexibility. Factory-integrated system eliminates position sensing cylinders. Antennas integrated into the cab roof for better protection. More intuitive 10-inch (254 mm) touchscreen display is easier to use.
AutoCarry™ automates blade lift to maximize blade load, improve load consistency, reduce track slip.
Cat Stable Blade works with electro-hydraulic controls to complement the operator’s blade-control input to get better finish grades faster and with less effort.
Cat Slope Indicate displays machine cross-slope and fore/aft orientation on the primary monitor, helping operators work more accurately on slopes.
Factory Attachment Ready Option (ARO) simplifies installation of all brands of grade control system.
Product Link™* collects machine data that can be viewed online through web and mobile applications.
Access information anytime, anywhere with VisionLink® – and use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety and security on your job site.
Ease of Operation
Fast response with intuitive, precise electro-hydraulic controls. Adjust sensitivity to fine, medium or coarse.
Liquid Crystal Display (LCD) is easy to read – includes your Slope Assist and rear camera displays (if equipped).
Power Pitch option lets you easily adjust blade to optimum pitch for your application using buttons on the right hand control.
Automatic Traction Control reduces track slip in poor underfoot conditions.
Rear vision camera provides enhanced visibility.
Easy to transport without blade removal.
Serviceability
Grouped maintenance and diagnostic points, as well as ground level service and Diesel Exhaust Fluid fill access.
Track roller frame designed for easy cleanout.
Optional bracket mounts to rear of machine to keep a shovel handy.
Diesel Particulate Filter designed for the life of the engine – no need to clean out.
Product Parameter
Overview
The D6K2 dozer is smarter and more efficient than ever. It comes equipped with GRADE technologies like Slope Assist and GRADE with 3D 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.
