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.
