Komatsu D85EXi-18 Large Dozer Specifications
Dozers Specs
The Komatsu D85EXi-18 is a highly productive large dozer designed to deliver exceptional efficiency and precision on Australian civil construction, mining, and bulk earthmoving sites. Featuring Komatsu’s intelligent Machine Control (iMC) system, this dozer automates blade control from rough dozing to finish grading, significantly reducing cycle times and operator fatigue while maximising material moved.
Powered by a fuel-efficient, emissions-compliant Komatsu engine, the D85EXi-18 combines robust tractive effort with the innovative SIGMADOZER blade to improve productivity by up to 15% compared to conventional semi-U blades. Its durable undercarriage and advanced hydrostatic steering system ensure outstanding stability, manoeuvrability, and long-term reliability in the harshest Australian operating conditions.

Additional Information
The Komatsu D85EXi-18 stands out due to its fully integrated intelligent Machine Control (iMC) technology, which eliminates the need for external masts and cables on the blade. The system automatically controls blade load and prevents track slip, allowing both experienced and novice operators to work at peak efficiency. Combined with the unique SIGMADOZER blade design, which rolls material towards the centre to reduce spillage, this dozer delivers unmatched fuel efficiency and production rates on bulk earthworks.
