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

    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

    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

    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

    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

    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 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

    Robust undercarriage

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