2 C r a W l e r d o z e r 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 m yd 3 / Full-U dozer 22.0 m yd 3 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). 2 Track link design reduces maintenance cost by making turning pins easier, with improved pin reuse (p.9). Low-drive, long-track, eight roller undercarriage provides outstanding grading ability and stability. Track shoe slip control system reduces operator fatigue (p.7).

Palm Command Control System (PCCS) Electronic controlled PCCS travel control Hydraulic controlled PCCS blade/ripper control Fuel control dial Automatic/manual gearshift selectable mode Gearshift pattern preset function ECMV controlled transmission (p.5) Rear attachments (optional) Variable giant ripper Multi-shank ripper Counterweight KOMTRAX Plus provides efficent monitoring of machine conditions for maximum productivity (p.9). Photosmayincludeoptionalequipment. K-Bogie undercarriage system improves traction, component durability, and operator comfort (p.6). Extra-low machine profile provides excellent machine balance and low center of gravity. 3
