The D65EXi/PXi-18 bulldozer 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. With lock-up torque converter and excellent vision, the D65EXi/PXi-18 is a reliable and versatile dozer. And it comes standard with, Komtrax, Komatsu's wireless fleet monitoring system ITC and Intelligent machine control reporting, backed by our Australia-wide service and support network.

Features and benefits
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.

Tier 4 engine KDPF regeneration video
As the technology of diesel engines has progressed from Tier 3 to Tier 4 Final, design aspects of the engines have been fine-tuned to comply with regulations to cover regulated diesel engine exhaust pollutants.
The result is that these new diesel engines are cleaner than ever before, and in many cases more fuel efficient too. Along with this comes the need to properly manage and maintain these new generation of machines to make sure that operating costs are minimised.
