Caterpillar Introduces First High-Drive Electric-Drive Dozer

An all-new Cat D6 dozer takes efficiency and performance to new levels.

The D6 XE is the world’s first high-drive electric drive dozer, offering up to 35-percent better fuel efficiency and increased agility compared to the previous, 3-speed model D6T. Constant power to the ground, continuous push and greater maneuverability mean faster cycle times, making Electric Drive a top choice to achieve the highest level of productivity and fuel efficiency.

D6 is powered by a 4-speed, fully automatic transmission that provides increased productivity and up to 20-percent better fuel efficiency versus its 3-speed predecessor. The fully automatic D6 reduces momentary hesitation when the traditional machine shifts, so more momentum and drawbar power are maintained through the entire push. Designed to work up and down the entire working range, power to the ground and fuel consumption are optimized for a greater percentage of the time. An added gear between first and second ensures more seamless shifting.
Both power trains offer unprecedented ease of operation – simply set the ground speed and the dozer continuously optimizes for maximum power and efficiency, based on load.

A new, purpose-built Variable Power Angle Tilt (VPAT) dozer grades at higher speeds, finishing jobs faster. The structure is stronger, yet lighter, so machine balance is optimized for grading without the need for a rear implement or counterweight. A wide-gauge, low ground-pressure VPAT design, with 36-inch centered shoes, puts more track on the ground to achieve 5 psi ground pressure.

Wider VPAT blade and class-leading range of motion improve performance, especially in trenching and backfilling applications. A new, optional finish grading undercarriage has 10 bottom rollers for smoother grades at higher speeds, even in difficult surfaces like sand and gravel.
The new D6/D6 XE is designed specifically to reduce service and maintenance costs by up to 12 percent, with updated components, longer service intervals and fewer scheduled maintenance tasks.

Undercarriage updates are designed to save money and maximize service life. A new heavy-duty, extended-life undercarriage features Positive Pin Retention pins and link improvements for up to 20-percent more seal life in high-impact conditions.

A new Cat C9.3B diesel engine has a redesigned fuel system that provides greater durability and more accurate fuel delivery. Elimination of the NOx Reduction System and a simplified single engine Electronic Control Module (ECM) help increase reliability.

A completely redesigned cab raises the standard in comfort and productivity. The standard air suspension seat is wider with added backward adjustment, plus the entire armrest adjusts independent of the seat for customized comfort. added throughout the cab.
