Innovative SIGMADOZER reduces digging resistance and smoothly rolls material up for increased blade loads.
Blade capacity:
5.6 m³ / 7.3 yd³ (for EX)
5.9 m³ / 7.7 yd³ (for WX)

Automatic transmission with lockup torque converter improves fuel consumption.

SAA6D114E-5 variable geometry turbocharged and aftercooled 8.85 liter diesel engine provides excellent fuel economy. This engine is EPA Tier 4 Interim and EU Stage 3B emissions certified.

Komatsu Variable Geometry Turbocharger (KVGT) uses a hydraulic actuator to provide optimum air flow under all speed and load conditions.

Komatsu Diesel Particulate Filter (KDPF) captures 90% of particulate matter and provides automatic regeneration that does not interfere with daily operation.

Rear hydraulics (standard)

Rear view monitoring system (standard)

Advanced diagnostic system continuously monitors machine operation and vital systems to identify machine issues and assist with troubleshooting.

Integrated ROPS cab features:
■ Large, quiet, and pressurized cab
■ Excellent visibility with integrated ROPS structure
■ New heated air-ride seat with 15% higher capacity

Parallel Link Undercarriage System (PLUS) provides up to double the wear life and lower repair & maintenance costs.

Hydrostatic Steering System (HSS) provides smooth, quick, and powerful control in various ground conditions. (Counter-rotation is available when in neutral.)

Self-adjusting idler support provides constant and even idler tension, reducing vibrations and increasing undercarriage life.

Power Angle Tilt (PAT) dozer with manually adjustable blade pitch expands productivity in a variety of applications.

Complete operator control
■ Palm Command Control System (PCCS)
■ Automatic/manual shift selectable mode

Steering System    
Palm Command Control System (PCCS) lever controls for all directional movements. Pushing the PCCS lever forward results in forward machine travel, while pulling it rearward reverses the machine. Simply tilt the PCCS lever to left to make a left turn. Tilt it to the right for a right turn.    
Hydrostatic Steering System (HSS) is powered by steering planetary units and a hydraulic pump and motor. Counter-rotation turns are also available. Wet, multiple-disc, pedal-controlled service brakes are spring-actuated and hydraulically released. Gear shift lock lever also applies parking brake.
