Rearview monitoring system (standard)

Six working modes are designed to match engine speed, pump delivery, and system pressure to the application.

Large displacement high efficiency pumps provide high flow output at lower engine speed, improving efficiency.

Komatsu's Closed-center Load Sensing System (CLSS) provides quick response and smooth operation to maximize productivity.

Komatsu Auto Idle Shutdown helps reduce nonproductive engine idle time and reduces operating costs.

Grip strut walkways and handrails located on the machine upper structure provide a convenient work area on both sides of the machine and in front of the engine.

Komatsu designed and manufactured components including forestry front, road builder front, forestry cab, undercarriage, engine, hydraulic pumps, hydraulic motors, control valves and hydraulic cylinders provide high reliability and durability.

KOMTRAX® equipped machines can send location, service meter reading and operation maps to a secure website or smart phone utilizing wireless technology. Machines also relay error codes, cautions, maintenance items, fuel & Diesel Exhaust Fluid (DEF) levels, and much more.

A powerful Komatsu SAA6D107E-3 engine provides a net output of 147 kW 196 HP. This engine is EPA Tier 4 Final 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) and Selective Catalytic Reduction (SCR) system reduce particulate matter and NOx while providing automatic regeneration that does not interfere with daily operation.

Wide fin radiator, hydraulic oil cooler and charge air cooler cores provide high capacity cooling.

Komatsu 40' reach live heel forestry front delivers high production log loading and shovel logging.

Powerful PC390-class swing motor and drive with 75,902 ft lbs swing torque provides high productivity.

Komatsu rugged high & wide forestry undercarriage uses compo-nents from the next-size larger Komatsu excavator for increased per-formance, reliability and durability, 11'5" (3492 mm) transport width.

PC360-class final drives with high 64,520 lbf drawbar pull provide excellent maneuverability and shovel logging performance.

Heavy duty forestry guarding package designed specifically for demanding logging applications.

Komatsu ROPS/OPS/FOPS/TOPS/FOG/WCB/Oregon OSHA certified forestry cab provides a comfortable working environment • High back, fully adjustable heated air suspension operator seat with adjustable arm rests • Low profile pilot proportional control (PPC) levers with electro-proportional control (EPC) for attachments provide for smooth work equipment operation. • All LED lighting provides excellent illumination • 48" hydraulically tilting or 7" fixed riser

Large 7" high resolution LCD color monitor panel: • Provides "Ecology Guidance" for fuel efficient operation • Enhanced attachment control

PERFORMANCE, RELIABILITY AND FUEL ECONOMYRugged front equipment, high & wide undercarriage and powerful swing sys-tem designs deliver high performance in demanding log loading, shovel logging and road building applications.

A fully-certified forestry cab provides a comfortable working environment.Enhanced controller logic and new Tier 4 Final engine technology providesexcellent performance and fuel efficiency.
