Features and benefits
Compact design
For working in tight areas, a compact short tail swing offers maneuverability in more confined areas than a conventional excavator, such as in a single lane of traffic. The conventional boom design has a greater raising angle to reduce the front bucket swing radius.
Fast cycles and custom modes
Faster boom up/swing speed, combined with responsive quick arm speed, makes excavating and leveling work easier and more efficient over previous models. Six working modes let you tailor the machine to the tasks required, whether it be for performance or fuel savings.
Versatility and efficiency come standard
Standard high flow auxiliary hydraulics with proportional joysticks allows you incredible job versatility while providing precise attachment control. Standard grading blade with new moldboard profile improves backfilling and light grading efficiency over previous models.
Maximum operator comfort
Operators work comfortably in a quiet, climate-controlled cab featuring air suspension seat, Bluetooth radio, and high-resolution monitor with rearview camera. LED lights provide excellent vision at night. Sliding cab door makes entry and exit easier in confined spaces.
Fuel efficient, low-cost power
The new high-efficiency power package and viscous fan clutch work together to lower overall fuel consumption up to 13%*. A smart, simplified catalytic system removes soot without a diesel particulate filter, meaning lower cost of ownership and less maintenance.
Quick and easy maintenance
Periodic maintenance is more accessible and efficient with large service access doors and grouped service points with ground-level access.
