Additional Information
The Komatsu D65EXi-18 stands out in the Australian market due to its fully integrated intelligent Machine Control (iMC) system. Unlike aftermarket add-on systems, Komatsu’s factory-installed iMC features integrated sensors that eliminate the need for external masts and cables on the blade. This technology enables automatic dozing from first pass to final grade, maximising load efficiency and preventing track slip. Combined with the fuel-saving Sigmadozer blade and an automatic transmission with lock-up torque converter, the D65EXi-18 delivers up to 15% higher productivity compared to conventional models.
