Power and Efficiency

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

Eco Modes optimize engine speed, while maintaining ground speed, saving up to 17 percent fuel in lighter blade load applications like finish grading.

Reduced Idling

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.

Traction Control

New automatic traction control is standard and automatically reduces track slip in poor underfoot conditions, improving productivity and finish surface quality.

Effective Cooling

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.

Operator Station

Operator Station

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.
  • Improved implement valve provides faster response. Intuitive, precise electro-hydraulic controls with sensitivity adjustment – fine, medium, coarse.
  • Rear vision camera (Optional) for enhanced visibility behind the machine.
  • Improved heating/ ventilation/air conditioning system cools faster; circulates air closer to the operator for more comfort.
  • New bi-directional control (Standard) – dial preselected forward/reverse gears for reduced effort and improved efficiency. Save the settings as operator profile for even more convenience.
  • Added comfort options like heated/ventilated seat and heated control handles.

Ease of Operation

Ease of Operation

Intuitive and precise

Whether the D6K2 is a permanent part of your fleet or rented for the short term, operators will find this machine easy to operate.

  • Technologies like Slope Assist and Stable Blade are integrated right into the dozer to help even less experienced operators achieve a quality grade more quickly, and with fewer inputs.
  • Joystick controls are intuitive and precise.
  • Machine balance and undercarriage are designed for faster finish grading.
  • A rear vision camera is available to enhance visibility behind the machine.
  • Machine width and folding blade option allow for easy transport.

Emissions Technology

Emissions Technology

Proven, integrated solutions

  • Meets Tier 4 Final/Stage IV/Korea Tier 4 emission standards.
  • 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.
