Komatsu’s intelligent Machine Control (iMC) D85EX/EXi/PX/PXi-18 bulldozers incorporate a fully factory integrated blade control system, so they can 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 the dozer comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.

Features and benefits
Ergonomic control system
Palm command travel joystick provides the operator with a relaxed posture and superb fine control without operator fatigue. Transmission gear shifting is simplified with thumb push buttons.
Unrivaled blade visibility
The D85EXi/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 D85EXi/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
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.
