Available in standard and low-ground-pressure undercarriage versions, our 9.48-9.54 tonne D39EX/PX-22 Komatsu bulldozer delivers industry-leading visibility to the blade through its forward-sloping bonnet design, plus a highly efficient hydrostatic transmission. It’s ideal for applications across civil construction, local government and other sectors. 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 remote monitoring and location system, backed by our Australia-wide service and support network.
Resources
Features and benefits
High productivity and low fuel consumption
This engine is EPA Tier 3 emissions certified; "ecot3" - ecology and economy combine with Komatsu technology to create a high performance engine without sacrificing power or productivity. The powerful Komatsu engine makes this dozer fuel efficient and the logical choice in both grading and dozing operations.
Comfortable ride with cab damper mounting
The cab mount uses a cab damper system that provides excellent shock and vibration absorption which conventional mounting systems are unable to match. The silicon oil filled cab damper mount helps to isolate the cab from the machine body, suppressing vibration and providing a quiet, comfortable operating environment.
Modular design
The design goals behind this dozer was to manufacture a more durable machine. This was achieved by reducing component complexity and using a strong modular design for increase serviceability and durability.
