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 driven radiator cooling fan
controlled automatically, reduces fuel consumption and operating noise levels.

SAA6D170E-5 turbocharged after-cooled diesel engine provides an output of 391 kW / 525 HP with excellent productivity. This machine is EPA Tier 3 and EU stage 3A emissions certified.

Preventative maintenance:
• Centralized service station
• Enclosed hydraulic piping
• Modular power train design
• Oil pressure checking ports

Simple hull frame and monocoque track frame with pivot shaft for greater reliability.

Large blade capacities:
18.5 m³ / 24.2 yd³ (Semi-U dozer) and 22.0 m³ / 28.8 yd³ (U dozer)

The Dual tilt dozer increases productivity while reducing operator effort.

Automatic lockup torque converter saves fuel and increases speed and power transmission efficiency on long pushes.

New track link design reduces maintenance cost by making turning pins easier with improved pin reuse.

New hexagonal designed cab includes:
• Spacious interior
• Comfortable ride with new cab damper mounting and K-bogie undercarriage
• Excellent visibility
• High capacity air conditioning system
• PCCS (Palm Command Control System) lever
• Pressurized cab
• Adjustable left armrest
• Travel control console integrated with operator seat

VHMS (Vehicle Health Monitoring System) with ORBCOMM provides efficient monitoring of machine conditions for maximum productivity.

Extra-low machine profile provides excellent machine balance and low center of gravity.

ECMV (Electronic Controlled Modulation Valve) controlled steering clutch/brake system facilitates smooth and shockless steering operation.

Rippers (optional):
• Variable giant
• Multi-shank

K-Bogie undercarriage system improves traction, component durability, and operator comfort.

Low-drive, long-track, eight roller undercarriage provides outstanding grading ability and stability.

Track shoe slip control system reduces operator fatigue.
