Our smallest excavator is a tough and productive machine in a small package, perfect for rental fleets, owner-operators, builders, plumbers, electricians and other tradies – or anyone who needs to work in confined conditions. It incorporates features of bigger Komatsu excavators, with key components designed and manufactured by Komatsu to work together in an integrated package. And it’s standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.

    Features and benefits

    Expandable undercarriage

    Expandable undercarriage

    The PC18MR-3 can pass through narrow space due to narrow width and undercarriage can be expanded for good stability during excavation.

    Tight tail swing

    Tight tail swing

    Operator is able to focus on the work in front of them and worry less about a rear swing impact, even in confined areas with only an 80mm 3" projection over the tracks.

    Closed-center load sensing system

    Closed-center load sensing system

    When two or more actuators are operated simultaneously, the pressure-compensated CLSS system ensures each actuator works according to its control input, regardless of the size of the load. This gives the operator precise control at all times.
