D65EXi/PXi-18 Dozers

The D65EXi/PXi-18 dozer incorporates Komatsu’s unique intelligent Machine Control (iMC) technology, allowing it to carry out both bulk and final trim dozing in fully automatic mode from start to finish, delivering final grade performance and accuracy. Available in both standard and low-ground-pressure versions, it is powered by 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.

  • 162 kW / 217 HP
  • 23,373 kg
  • 5.6 m³

Improved Machine Efficiency

The new D65EXi/PXi-18 has achieved both high levels of productivity and fuel economy with the SIGMADOZER blade, 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 D65EXi/PXi-18 has a strong integrated ROPS cab. High rigidity and superb sealing performance sharply reduce noise and vibration for the operator and helps prevent dust from entering the cab. This provides the operator a comfortable working environment. In addition, side visibility is increased because additional extrenal ROPS structure and posts are not required.

Comfortable Working Space

The D65EXi/PXi-18's cab mount uses a cab damper system and provides shock and vibration absorption conventional mounting systems cannot 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.
