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.
