Power & transmission
The D65-18's automatic transmission automatically selects the optimal gear for dozing operations and includes a travel speed preset function to reduce cycle times and operator fatigue. Komatsu ECMV (Electronic Controlled Modulation Valves) ensure smooth, precisely timed gear changes to maintain efficient power transfer.

Operator comfort
Quiet, comfortable cab with hexagonal design and large tinted glass for panoramic visibility. High-capacity automatic climate control pressurises the cab to keep dust out, while sound-absorbent lining reduces interior noise.

Safety
Redesigned integrated ROPS/FOPS cab and well-positioned operator seat provide optimal left and right blade visibility for safe dozing and grading. Special fuel tank shape improves rear and ripper point sightlines.

Environment & engine
Komatsu EU Stage V engine provides ultra-low emissions while delivering dependable, efficient performance to reduce operating costs and environmental impact.
