earthmoving or finish grading.

Cat Grade Control 3D

(available early 2016) is an

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

Cat AutoCarry

system and the

AccuGrade Ready

option are included in the package to further boost

productivity and versatility.

Cat AccuGrade 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 sys-

tems using a Universal Total Station (UTS) for fine and

finish grading.

AccuGrade now utilizes components of the Slope

Assist system to provide an even higher level of grading

performance than was previously achievable.

AccuGrade Ready Option allows you to easily install

or upgrade to Cat AccuGrade 2D and 3D grade-control

systems to add versatility and resale value to your

machine.

More Fuel Efficient

Fuel-efficiency gains result primarily from the D6N’s new

transmission with a lock-up clutch torque converter that

seamlessly selects the drive mode best suited to the

application.

The transmission provides the performance of direct

drive with the ease of operation of power shift. Fuel

savings range from 10 – 15%, and productivity gains in

typical applications are estimated at up to 10 percent,

compared with the previous model.

The standard Enhanced Auto Shift system, combined

with the lock-up-clutch control, allows operators to select

the optimum ground speed for the load being moved,

resulting in further fuel savings. In addition, an electron-

ically controlled, variable-speed demand fan automati-

cally adjusts its speed to conserve engine horsepower

and fuel, and reduce sound levels.

Ease of Operation

The updated cab has more leg room and wider, easi-

er-closing doors. A smoother-shifting transmission and

quieter engine create a more comfortable environment,

and operator-selected electro-hydraulic mapping fine

tunes implement response (fine/normal/coarse) to suit

operator preference or tailor the machine to the

application.

The instrument display and operator interface have

been updated and are now common with other Cat

dozers. Performance of the HVAC system is significantly

improved, and an improved fresh-air filter keeps the cab

cleaner.

For added safety, a new seat-belt-indicator system

registers a fault code through Product Link if the operator

fails to buckle up.

Serviceability

The new dozer is designed for ease of maintenance,

providing a ground-level service centre for easy access

to the electrical disconnect, hour meter and remote light

switch.
