Original Press Release:



Cat® D6R Series II Track-Type Tractor Offers Higher Productivity at a Lower Cost Per Yard



The D6R Series II track-type tractor from Caterpillar features a new electronic C9 engine that meets emissions requirements for the United States, Europe and Japan, plus other improvements that increase productivity and reduce operating costs. The Series II machine retains the best features of the D6R track-type tractor, including modular components for faster service, the rugged and reliable elevated sprocket design, Cat's exclusive Advanced Modular Cooling System (AMOCS) and a differential steering option. Numerous power train, cab and serviceability improvements make the D6R Series II track-type tractor an even more valuable tool than its predecessor.

Advanced power train technology
A Caterpillar® C9 engine powers the D6R II. It features an electronically controlled, hydraulically actuated direct-injection fuel system that improves fuel economy and reduces emissions. Air-to-air aftercooling also helps minimize emissions and boost engine performance. The engine is rated at 165 net horsepower (123 kilowatts) when the machine is equipped with standard undercarriage. With XL, XW or LGP configurations, net power is 185 horsepower (138 kilowatts).

The torque divider and transmission are matched to the engine to optimize performance and component life. The planetary powershift transmission now features Load Compensating Shifting, which automatically adjusts the clutch engagement timing according to load factors. This results in improved tractor performance and operator comfort during speed changes.

Comfortable, productive work environment
The D6R II has a spacious cab, isolation-mounted and pressurized to reduce sound and vibration. The operator has clear views of the blade and ripper tip. The machine is equipped with a fully adjustable Cat Comfort Seat to reduce fatigue. Ergonomically designed, pilot-operated controls for the blade and ripper improve productivity. The differential steering system and electronic Finger Tip Control (FTC) clutch and brake deliver outstanding maneuverability and control. A newly designed instrument panel helps keep the operator informed, and the Cat Monitoring System provides instant feedback about operating conditions, as well as valuable information for diagnostics. The monitoring system has software-flashing capabilities for fast, easy upgrades. Other improvements to the cab include new footpads adjacent to the dash, which provide stability and comfort while working on side slopes, and a new hydraulic lock-out valve that prevents inadvertent operation of the work tools.

Simplified service
The D6R Series II track-type tractor is designed for easy service. Most major components can be removed and installed as modules, reducing repair time. Cooling system cores can be removed individually without removing the radiator, decreasing service time and increasing uptime. The engine oil change interval is extended to 500 hours. Implement valves are easier to access. Pressure test points are provided for fast hydraulic and power system checks. When repairs are needed, the D6R II accommodates electronic diagnostic tools to reduce service time and increase uptime.

An optional Product Link System can be factory installed or easily retrofitted to simplify fleet tracking. The wireless system uses satellite technology, the Internet and the customer's Cat dealer storefront website to monitor and report key machine parameters such as location, hours and service codes.
