Powered by a new technology Komatsu engine, the D375A-8 bulldozer sets the industry standard in terms of operator comfort and control, while delivering higher production and lower operating costs for mining and heavy construction applications. As with all our dozers, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our Komtrax Plus remote monitoring and location system, backed by our New Zealand-wide service and support network.

    Features and benefits

    Heavy-duty aftertreatment system

    Heavy-duty aftertreatment system

    KDPF captures more than 90% of Particulate Matter (PM). Special oxidation catalyst and extra fuel injection in the exhaust stream can decompose accumulated soot in the KDPF filter by either active or passive regeneration. This system does not require any additional operator's action or interrupt normal operation.

    Heavy-duty cooled Exhaust Gas Recirculation (EGR) system

    Heavy-duty cooled Exhaust Gas Recirculation (EGR) system

    The system recirculates a portion of exhaust gas into the air intake and lowers combustion temperatures, thereby reducing NOx emissions. While EGR gas flow isincreased, by incorporating a high-efficiency and compactly designed cooling system, the system achieves a dynamic reduction of NOx, while helping to reduce fuel consumption.

    The Komatsu D375A mining dozer is equipped with a low drive undercarriage

    Equipped with a low drive undercarriage designed to help reduce wear and tear on your machine while still delivering comfort and stability. Minimal moving parts to help maintain high levels of traction and production when dozing and ripping. Whether you are looking to keep blasting, loading and dump areas clean, or construct and maintain haul roads, dozers have a direct impact on your fleet’s productivity. With new mainframes featuring twice the design life over previous models, the D375A-8 is engineered to be powerful and durable.
