Cat has updated its D6T bulldozer with a new transmission that the company says makes the machine not only easier to operate but much more fuel efficient.
The new machine is powered by a Tier 4 Final Cat C9.3 ACERT delivering 215 horsepower (253 gross). The engine is now paired with a fully automatic, four-speed, power-shift transmission with an integral lock-up clutch. Cat says the new transmission is capable of reducing fuel use by up to 20 percent in heavy work and up to 30 percent in light work and finish grading applications.
Operation with this new automatic transmission is as simple as setting the ground speed. From there the transmission chooses the gear and engine speed that are most efficient for current operating conditions.
For smoother shifting and in order to maintain power to the ground during load changes, the transmission adds a gear between the first and second ranges. Cat says this added gear also allows the machine to “remain in the most efficient mode” for longer periods of time.
Cat says the effect of this new transmission is “an aggressive feel in the dirt,” while boosting productivity by 2.5 percent.
GRADE technology standard
Further increasing productivity is a suite of Cat’s GRADE technologies. The following come standard on the new machine:
♦ GRADE with Slope Assist: A new standard feature, this system automatically maintains pre-established blade positioning without the need for added hardware or a GPS signal.
♦ Slope Indicate: Displays machine cross-slope and fore/aft orientation on the primary monitor
♦ Stable Blade: Assists operator blade-control input to require less effort
The following are available options:
♦ GRADE with 3D: This factory-integrated grade control system provides 3D guidance for production dozing and fine grading. It features roof-mounted antennas rather than blade-mounted. Cat AccuGrade is included with the system along with Cat’s AutoCarry system which adjusts the blade for optimum load retention.
♦ AccuGrade: This dealer-installed aftermarket grade control system gives scalable flexibility for changing needs, and ranges from lasers for 2D flat-plane and slope work, to GNSS systems or universal total stations for more complex contours and finish grading.
♦ AccuGrade Ready: This factory configuration makes the D6T able to more quickly accept an upgrade to AccuGrade 2D or 3D systems.
Cat notes that the D6T also comes with its Product Link telematics system integrated. Product Link provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes and other machine data on demand through its VisionLink online interface.
The Cat D6T has an operating weight range between 47,846 and 54,526 pounds. Blade capacity ranges between 4.96 and 7.38 cubic yards.
