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. SAA12V140E-3 turbocharged aftercooled diesel engine provides a net output of 664 kW 890 HP with excellent productivity. This machine is Tier 2 EPA, EU, and Japan emissions certified. The Super Dozer The D475A-5 Super Dozer greatly contributes to reducing operating costs ($/tons) by high dozing productivity. • Large capacity Super Dozer blade with low dozing resistance Low noise • Operator noise: 70dB(A) (Engine at high idle, cooling fan at 70%, and air conditioner OFF.) • Dynamic noise (outside): 110dB(A) As per ISO 6395 Hydraulic Driven Engine Cooling Fan controlled automatically, reduces fuel consumption and operating noise levels. Extra-low Machine Profile provides excellent machine balance and low center of gravity. The Dual Tilt Dozer increases productivity while reducing operator effort. Large blade capacity: 45 m³ / 58.9 yd³ (Super Dozer). Automatic transmission with lockup torque converter increases speed and power to improve fuel consumption and productivity. Track Link With Wedge Ring reduces maintenance cost by making turning pins easier, with improved pin reuse. Hexagonal Designed Cab Includes: • Spacious interior • Comfortable ride with viscous cab damper mounting • Excellent visibility • High capacity air conditioning system • Palm Command Control System (PCCS) lever controls • Pressurized cab • Multi-position adjustable armrest • Travel control console integrated with operator seat KOMTRAX Plus provides efficient monitoring of machine conditions for maximum productivity. Preventative Maintenance • Centralized Service Station • Enclosed Hydraulic Piping • Modular Power Train Design • Oil Pressure Checking Ports Rear Attachments (optional) • Variable giant ripper • Counterweight Electronic Controlled Modulation Valve (ECMV) controlled steering clutch/brake system facilitates smooth and shockless steering operatio. K-Bogie Undercarriage System improves traction, component durability, and operator comfort. Track shoe slip control system reduces operator fatigue and improves undercarriage life. Low-drive, long-track, eight roller undercarriage ensures outstanding dozing ability and stability.
