RELIABILITY YOU CAN COUNT ON

Protect hydraulic components in cold weather. The auto warm-up feature speeds hydraulic oil warming in cooler temperatures.
The fuel system is protected from contamination of fuel by three levels of filtration.
Bottom guarding protects engine and hydraulic components from damage while swinging and traveling.
The hydraulic tank with a new oval shape designed to improve stress resistance.
The strong X-structure lower frame carries loads from the excavator's upper structure to the track.
Travel motor hydraulic lines are routed inside of the frame to protect them from damage.
The sloped track frame design prevents mud and debris from accumulating and damaging tracks.
The grease lubricated tracks have grease sealed between the pin and bushing to prevent debris from entering and reducing life.
The track rollers are rebuild-able and sealed to prevent dirt and debris causing wear of internal components.
A bolt-on track guiding guard helps maintain track alignment while traveling or working on slopes.

SIMPLE TO OPERATE

Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the Operator ID passcode.
Program each joystick button, including response and pattern, using Operator ID; the machine will remember what you set each time you go to work.
Program up to four depth and slope offsets so you can easily get to grade without a grade checker – a real time saver and safety enhancer on the jobsite.
Save more time and energy with available work tool recognition. A simple shake of the attached tool confirms its identity; it also ensures all the attachment settings are correct so you can get to work quickly and efficiently.
Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor, or with the optional 254 mm (10 in) touchscreen monitor, or with the aid of the jog dial control.
