Fuel economy improves 6 percent compared to the Dash 6 version with a Cummins Tier 4-F engine with DEF. Auto-idle reduces engine speed when the machine is in neutral. Bucket capacity has been boosted 4.5 percent to 9.2 cubic yards, and the machine has optimized swing control. An upgraded hydraulic system has a flow regeneration valve that reduces power requirements.
The undercarriage has three single-sided upper rollers on each side of the track frame that help maintain shoe clearance and reduce debris buildup, the company says. The boom and arm are welded using a full-box section design.
The cab rests on 6-point, support type, fluid-filled elastic mounts for reduced shocks and vibrations. A center track frame disperses stress, and an improved track link design includes oil-filled idlers and rollers that eliminate the need for daily lubrication.
The cab is pressurized, with climate control, and the seat can be adjusted to customize suspension settings. Aerial Angle is a 360-degree vision system that notes surroundings through a display monitor that combines a set of images captured by cameras positioned around the machine.
