With a strong Cat C9 engine, the Cat® D6R from Caterpillar handles jobs ranging from land clearing to heavy dozing/ripping to fine grading duties on construction.

Contractors who are looking for a rugged, reliable dozer with cost-reducing features like fuel efficiency and ease of maintenance, can find it in the new Cat® D6R. With a strong Cat C9 engine, this versatile new machine handles jobs ranging from land clearing to heavy dozing/ripping to fine grading duties on construction, road and industrial development sites, to landfill service duties in waste disposal sites. The D6R features a tough power-shift transmission, differential steering, heavy-duty undercarriage, comfortable cab with intuitive low-effort controls and a range of blade types.

Building on components and features that have given Cat Track-Type Tractors a global reputation for quality and long life. The C9 engine with ACERT™ Technology provides optimal engine performance, reliability, exceptional fuel efficiency and is capable of meeting EPA Tier 2 and EU Stage II emission levels and is certified to China Stage II (GB 20891-2007) emission standards.

Durable drive train

The D6R's engine drives a Cat torque divider that is coupled with a planetary power-shift transmission. The torque divider provides added efficiency by transferring 30 per cent of the engine's power directly to the drive train, while the remainder is transferred through the torque converter. This design, combined with the transmission's heavy-duty gearing, mechanical controls and large-diameter clutches, delivers steady power with unmatched dependability.

The D6R's durable, field-proven differential-steering system allows full power to both tracks in turns, allowing precise steering with maximum material retention for increased productivity. Because the system allows the tracks to turn at different speeds with full power, the operator can easily maintain straight-line travel when benching or working across slopes. The system uses robust planetary gearing and a strong hydraulic motor for steering control.

Strong, long-lasting undercarriage

The D6R is available with five undercarriage choices: heavy duty undercarriage in standard; LGP; XL configurations; and SystemOneTM as an option for the LGP and XL configurations. The standard configuration is suited to aggressive applications, including forestry and working in rocky or uneven terrain; the XL uses a longer roller frame and added track, placed toward the front of the machine, for optimum balance in general earthmoving to finish-grading applications; and the LGP, with a wider track gauge, wider track shoes and more track-on-ground performs efficiently in soft or swamp-like ground conditions. As all track rollers and idlers are lifetime lubricated, internal components can be reused with the option to either rebuild or re-shell to help drive lower operating costs.

The standard, LGP and XL configurations feature sealed-and-lubricated track chains, heavy-duty rollers, heavy-duty idlers, tubular roller frames and Cat Tough-Steel™ sprockets. D6R undercarriages deliver durable performance in severe operating conditions, significantly reducing operating costs by extending track-chain life with an allowable pin-and-bushing turn at mid-life.

The SystemOne undercarriage option further extends undercarriage life and reduces operating costs in many applications. Its balanced design allows the undercarriage to wear as a system and eliminates both pin-and-bushing turns and sprocket replacement.

Operator station, grade-control and serviceability

The D6R has a comfortable, quiet, pressurised cab that features the Cat Comfort Series Seat and pilot-operated, low-effort controls. Ergonomically designed handles for the blade and ripper reduce operator effort and fatigue, and the tiller-type steering bar also incorporates speed controls and provides a single operator control for all direction and speed selection. The pilot-operated controls provide precise/quick response and allow equipping the D6R with optional grade-control systems, including the Cat AccuGradeTM laser, UTS (Universal Tracking System) and GPS (Global Positioning System)configurations. These systems allow operators to attain more-precise grades with fewer passes.
