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 whose components are designed to work together for higher production, greater reliability, and more versatility. Hydraulic Drive Radiator Cooling Fan controlled automatically, reduces fuel consumption and operating noise levels SAA6D125E-3 turbocharged after-cooled diesel engineprovides an output of 197 kW / 264 HP with excellent productivity. This machine is EPA Tier 3 and EU Stage 3A emissions certified. Large Blade Capacity: 5.9 m³ / 7.7 yd³ (Straight Tilt Dozer) Planned Maintenance
• Centralized Service Station
• Enclosed Hydraulic Piping
• Modular Power Train Design Self-adjusting Idler Support
The self-adjusting idler support provides constant and even tension on idler guide plates, reducing noise and vibration and increases undercarriage life. The track link life is greatly improved through increased bushing diameter KOMTRAX^® equipped machines can send location, SMR and operation maps to a secure website utilizing wireless technology. Machines also relay error codes, cautions, maintenance items, fuel levels, and much more. New Hexagonal Designed Cab includes: • Spacious interior • Comfortable ride with new cab damper. • Excellent visibility • High capacity air conditioning system (optional) • PCCS (Palm Command Control System) lever • Pressurized cab (optional) • Adjustable armrests Extra-low Machine Profile provides excellent machine balance and low center of gravity Simple Hull Frame and monocoque track frame with pivot shaft for greater reliability Hydrostatic Steering System (HSS) provides smooth, quick, and powerful control in various ground conditions Low-drive, long-track, undercarriage ensures outstanding grading ability and stability
