D155AXi-8 Dozers

For high-production precision earthmoving and automatic blade control, our D155AXi-18 intelligent Machine Control (iMC) dozer, with its fully factory integrated blade control system, can take you towards your required level faster and helping to minimise rework on your jobs. Power comes from a new technology Komatsu engine. And it comes standard with our KOMTRAX remote monitoring and location system, backed by our Australia-wide service and support network.

  • 9.4 m³


Improved Machine Efficiency

The new D155AXi-8 has achieved both high levels of productivity and fuel economy with the SIGMADOZER blade and automatic transmission with lockup torque converter and new Tier 4 Final engine. From these 3 key features the bulldozer significantly improves  fuel efficiency compared with our conventional models

Unrivaled Blade Visibility

The D155AXi-8 has a strong integrated ROPS cab with large glass windows for outstanding visibility. High rigidity and superb sealing performance greatly reduce noise and vibration for the operator and helps prevent dust from entering the cab. The standard air-suspension seat positions the operator comfortably.

Hydrostatic Steering System

The engine power is transmitted to both tracks without power interruption on the inside track for smooth, powerful turns. Counter rotation while in neutral is available for minimum turning radius providing excellent maneuverability.
