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.

Dynapac has introduced a small project tandem asphalt roller with its CC950D, designed for bicycle paths, narrow roads, small parking lots and other hard-to-reach asphalt compaction applications.
The CC950D offers 38-inch-wide drums with a “high clearance” designed to allow it to work near curbs, the company reports. The front drum vibrates at 4,200 vpm, or 70 Hz, while the rear drum is static.
Dynapac added shock absorbers on the rear drum to lesson the impact on the operator, and designed “ergonomically positioned” steps to give the operator more comfortable access. It also features standard foldable rollover protection system (ROPS) framing for low-clearance transport.
