Innovative SIGMADOZER reduces digging resistance and smoothly rolls material up for increased blade loads. Blade capacity: 12.3 yd³ 9.4 m³ Automatic transmission with lockup torque converter improves fuel consumption. SAA6D140E-6 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 Hydrostatic Steering System (HSS) provides smooth, quick, and powerful control in various ground conditions. (Counter-rotation is available when in neutral.) Complete operator control ■ Palm Command Control System (PCCS) ■ Automatic/manual shift selectable mode ■ Shift pattern preset function Extra-low machine profile provides excellent machine balance and low center of gravity. Large color monitor ■ Easy-to-read and use large 7" high-resolution multi-color monitor ■ ECO guidance K-Bogie undercarriage system improves traction, component durability, and operator comfort. 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.
