Horsepower 359 HP @ 1,900 rpm
Operating weight 105,670 - 107,850 lbs.
Bucket capacity 1.47 - 4.15 yd³
Productivity and efficiency for mass excavation to fine grading
Excellent for mass excavating, trenching, or fine grading, our largest intelligent machine excavator can increase your productivity and efficiency without the worry of over-excavation from first to last pass, straight to grade.

Features and benefits
Adjusts to the operator's experience level
A fully integrated grade assist automatically traces the target surface to minimize over digging. A built-in facing angle compass ensures the machine is aligned with the target surface.

Auto stop control
To help eliminate potential damage during boom or bucket operation, the machine automatically stops when the bucket edge reaches the design surface.

Minimum distance control
iMC controls the bucket by automatically selecting the point closest to the target surface, which minimizes operator input while providing higher accuracy and grading confidence.

Critical precision for utility applications
For utility customers looking for the utmost precision, the excavator allows your operator to input structure, invert elevations of pipe runs and automatically calculates fall of pipe.

Powerful, advanced engine
Your fleet can be environmentally friendly without sacrificing power. Excavators with iMC 1.0 are equipment with a Tier 4 Final certified Komatsu SAA6D107E-3 engine, which features an integrated diesel particulate filter, hydraulically actuated Komatsu variable geometry turbocharger and selective Ccatalytic reduction system.

Stroke sensing hydraulic cylinder
Stroke sensing hydraulic cylinders provide real-time position that is immediately displayed to the operator. This is an improvement over conventional aftermarket machine guidance (indicate only) systems with tilt sensors that require time to stabilize.

Robust undercarriage
A large counterweight and robust undercarriage components help provide outstanding stability.
