Walk-around SAA6D170E-5 turbocharged aftercooled diesel engine provides a net output of 455 kW 610 HP with excellent productivity. This machine is EPA Tier 3 and EU stage 3A emissions certified (p.6).
Preventative maintenance ● Centralized Service Station ● Enclosed Hydraulic Piping ● Modular Power Train Design ● Oil Pressure Checking Ports (p.9) ● Multi-Monitor with Self Diagnostic Function ● KOMTRAX Plus
Komatsu-integrated design for the best value, reliability, and versatility. Hydraulics, power train, frame, and all other major components are engineered by Komatsu. You get a machine with components designed to work and wear together as a system for higher production, greater reliability, and more versatility.
Hydraulically driven radiator cooling fan controlled automatically, reduces fuel consumption and operating noise levels (p.6).
Automatic transmission with lockup torque converter increases speed and power to improve fuel consumption and productivity (p.6).
High efficiency blade provides a new blade profile to maximize prouctivity. Semi-U dozer 18.5 m3 24.2 yd3/ Full-U dozer 22.0 m3 28.8 yd3
Simple hull frame and monocoque track frame with pivot shaft for greater reliability.
The Dual tilt dozer increases productivity while reducing operator effort (p.6).
Track link design
Low-drive, long-track, eight roller undercarriage
reduces maintenance cost by making turning pins easier, with improved pin reuse (p.9).
provides outstanding grading ability and stability.
Track shoe slip control system reduces operator fatigue (p.7).
