Komatsu D65PXi-18 Large Dozer Specifications
Dozers Specs
The Komatsu D65PXi-18 is a highly advanced, production-class crawler dozer designed to deliver outstanding efficiency and precision on Australian civil construction, mining, and bulk earthworks sites. Featuring Komatsu’s intelligent Machine Control (iMC) system, this large dozer integrates 3D GNSS technology directly from the factory, allowing for automated rough dozing through to high-precision finish grading. The low ground pressure (PX) configuration, combined with wide track shoes, ensures exceptional stability and flotation in soft, wet, or challenging underfoot conditions.
Powered by a fuel-efficient, Tier 4 Final-compliant Komatsu engine, the D65PXi-18 offers an optimal balance of power and environmental responsibility. Its robust undercarriage, ergonomic operator cabin, and versatile blade options make it a preferred choice for major infrastructure projects, residential subdivisions, and resource sector applications across Australia. Whether performing heavy land clearing or precise site preparation, this machine maximises productivity while reducing operating costs.

Additional Information
The defining feature of the Komatsu D65PXi-18 is its fully integrated intelligent Machine Control (iMC) system. Unlike aftermarket add-on systems, Komatsu’s factory-installed 3D GNSS technology features no external masts or cables on the blade, eliminating the risk of damage and reducing wear. The system automatically controls blade lift and tilt based on real-time digital design data, preventing over-excavation and ensuring target grade is reached in fewer passes. Combined with the automatic transmission with lock-up torque converter, this dozer delivers up to 10% fuel savings and unmatched grading efficiency for Australian operators.
