KOMATSU’s new D175AX-10 large bulldozer is scheduled for release in November 2026, replacing the D155AX-8 launched in April 2016. The new model features comprehensive upgrades in productivity, operating performance, comfort, and maintenance convenience.

The D175AX-10 is equipped with a newly developed high-output, fuel-efficient engine, a four-speed transmission, and a large semi-U blade. Compared with the previous D155AX-8, straight dozing productivity increases by up to 25%, while turning dozing productivity improves by up to 19%. Blade capacity rises from 9.4 m³ to 10.6 m³, an increase of approximately 13%.

A newly developed steering system supports both power-turn and spot-turn functions, improving maneuverability in confined working areas. Intelligent controls use an inertial measurement unit (IMU) and sensors to coordinate transmission and steering, delivering smoother operation and reducing operator fatigue.

The upgraded cab offers improved front and rear visibility, a more intuitive control layout, and enhanced vibration and noise reduction. An eight-roller undercarriage improves ground contact, stability, and grading performance on uneven terrain.

For reliability and easier maintenance, the D175AX-10 features extended oil and filter replacement intervals, improved maintenance access, and a high-strength main frame designed for long-term durability. These upgrades help reduce lifecycle costs while supporting efficient and comfortable operation in demanding construction and mining applications.
