Tiller Bar Control System
A comfortable tiller bar provides precise steering, direction and transmission control, featuring: <ul><li> Easy touch shifting</li><li> Tight turning radius and counter-rotation capability</li><li> Smooth direction changes</li></ul>
Power Turn with Differential Steering
With differential steering, large blade loads can be smoothly maneuvered while turning. The operator maintains precise control on slopes, around buildings, bridge abutments, trees or other obstacles. <ul><li> Differential steering turns the machine by speeding up one track and slowing the other while maintaining full power to both.</li><li> Steering modulation is finely tuned for precise control.</li><li> Regardless of ground conditions, steering is consistent because power is maintained to both tracks during operation.</li></ul>
Cat® C6.6 Engine with ACERT™ Technology
The Cat® C6.6 is a 6.6 liters (403 in3) displacement, six cylinder, inline configured engine equipped with a Caterpillar Common Rail fuel System. It uses ACERT Technology, a series of Caterpillar engineered innovations that provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions. It meets the U.S. EPA Tier 3, European Union Stage IIIA and Japan MOC Step 3 emissions standards.
Electric Fuel Priming Pump
The electric fuel priming pump provides quick, effortless fuel priming.
The direct injection electronic fuel system provides a controlled fuel delivery increase as the engine lugs back from rated speed. This results in increased horsepower below rated power. A combination of increased torque rise and maximum horsepower improves response, provides greater drawbar pull and faster dozing cycles.
Multi Velocity Program (MVP)
Caterpillar’s Multi Velocity Program (MVP) allows operators to choose from five different speed ranges in both forward and reverse, increasing machine productivity, decreasing fuel consumption and significantly reducing operating costs.
Auto-shift allows the operator to select a forward and reverse speed combination for easy, efficient directional changes. The operator can select a combination of any forward and reverse speeds or use one of three factory settings. The factory auto-shift settings include: 1.5 forward/2.5 reverse, 2.5 forward/2.5 reverse, and 2.5 forward/1.5 reverse. Auto-kickdown allows the transmission to automatically downshift when significant load increases are detected, ensuring maximum dozing performance.
Elevated Final Drive
<ul><li> Isolates final drives from impact loads for extended power train life.</li><li> Protects sprocket teeth, bushings and final drives from debris, abrasive materials and moisture.</li><li> Provides long-lasting final drive performance and durability.</li></ul>
Designed for quiet, comfortable, productive operation all shift long. Large glass panels provide excellent visibility to the blade, sides and rear of the machine, for safe, effective operation in tight operating areas. Acoustic headliner material, and sound suppression foam panels ensure quiet machine operation, and automatic temperature control provides unmatched operator comfort.
Cat Comfort Series Air Suspension Seat
Cat Comfort Series Air Suspension Seat is fully adjustable for maximum operator comfort, support and reduced operator fatigue.
The instrument panel has been redesigned for improved visibility and usability. The easy to read gauges, warning lights and digital display ensure the operator is always aware of vital machine functions.
New electro-hydraulic controls provide quick steering response, precise blade control, and comfortable, low-effort operation. They offer superior ergonomics and are quieter and cleaner than pilot controls, eliminating hydraulic connections in the cab.
AccuGrade Attachment Ready Option
The AccuGrade Attachment Ready Option (AccuGrade ARO) provides a factory installed on-board platform for an AccuGrade Laser, GPS or Advanced Tracking Sensor (ATS) system. All of the changes required to the electrical system, hydraulic system, blade, and cab are incorporated into the AccuGrade ARO. Mounting brackets on the blade allow easy installation of the masts. Mounting brackets in the cab secure the in-cab display. Plug-in points inside the cab and on the front of the machine make it easy to install electronic components.
AccuGrade GPS System
The AccuGrade Global Positioning System (GPS) is the best solution when the construction site involves contours, rather than single or dual slope planes. A GPS system compares the blade position to a three-dimensional computerized job site plan and signals the operator or hydraulic system to raise or lower the blade to achieve the design requirements.
AccuGrade ATS System
The AccuGrade ATS system tracks blade positioning and provides three dimensional controlling capability for precise elevation adjustment, improved accuracy and dynamic tracking.
AccuGrade Laser System
The laser system is ideal for fine grading sites with flat, single slope or dual slope surfaces such as industrial, commercial and residential building sites.
The in-cab display with easy-to-read grade indicators and real time operator information provide the operator with all AcuuGrade system information. The display is designed for reliable performance in extreme operating conditions including shock, dust and moisture.
Exclusively for Caterpillar machines, the design extends system life and reduces operating costs.
XL (Extra Long) arrangement <ul><li> Forward idler position provides more track on the ground and to the front of the tractor. It provides optimal balance, superior traction and blade control for finish grading. </li><li> Long roller frame provides good flotation in soft underfoot conditions. LGP (Low Ground Pressure) arrangement</li><li> Specially designed to work in soft and spongy conditions. </li><li> Wide track shoes, a longer track frame and a wider gauge increase track contact area and reduce ground pressure for excellent flotation.</li></ul>
The pinned equalizer bar gives the roller frames the ability to oscillate up or down to better match ground contours while providing maximum traction and operator comfort.
Variable Pitch Power Angle and Tilt Blade (VPAT)
The VPAT blade gives the operator the ability to hydraulically adjust the blade lift, angle and tilt from the operator’s station. <ul><li> Manually adjustable blade pitch for optimum performance.</li><li> Top corners of the blade are clipped for better operator viewing area. (XL arrangement only).</li><li> C-Frame is solidly pinned to the mainframe for good blade control and eliminates blade motion due to track oscillation or side forces.</li></ul>
Designed to facilitate transportation without removing the blade, the foldable blades reduced overall shipping width of the machine. The blade can be folded by hand by one person without the need for tools, and each foldable blade includes the mounting brackets for AccuGrade masts.
The D6N can be equipped with a drawbar for pulling work tools such as disks, compactors, chopper wheels and retrieval of other equipment.
The multi-shank parallelogram ripper lets you choose one, two or three shanks depending on job conditions. Curved or straight ripper shanks are available.
Standard and slow-speed winches are available to match the application requirements. <ul><li> Integrated electronic controls for both clutch and brake functions improve winch performance. </li><li> Clutch engagement and brake release are automatically synchronized for smooth operation. </li><li> Winch components can be serviced with winch mounted on tractor. </li></ul>Check with your Caterpillar Dealer for details.
In forestry and land clearing applications where limbs and debris can damage a machine, optional sweeps are available for the D6N. Sweeps help to shield critical components on the tractor such as hydraulic lines, exhaust stacks, cab windows and lights from damage.
