D85EXi/PXi-18 Dozers

With a low-emission Tier 4 Final-compliant engine, our 27.65-28.1 tonne D85EX/PX-15EO dozer is available in standard and low-ground-pressure undercarriage versions, and a choice of Sigma and semi-U blades. Applications include civil construction, local government, waste management, agriculture and other sectors. As with all our dozers, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our KOMTRAX remote monitoring and location system, backed by our NZ-wide service and support network.

Improved Machine Efficiency

The new D85EXi/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 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.
