High capacity air suspension seat:• Seat mounted EPC controls with F-N-R switch • Seat heater is standard

New style of front fender is plastic for durability.

Rear full fenders (standard) are made of durable plastic and swing open for easy access to maintenance points.

Large LCD color monitor panel:• 7" high resolution screen • Provides "Ecology Guidance" for fuel efficient operation• KDPF and SCR DEF level monitoring

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

External mounting of engine air filter (above rear LH fender) provides easy access for maintenance.

New shape of engine hood accommodates addition of SCR for Tier 4 Final emissions compliance.

KomtRAx® sends information to a secure website including machine location, SMR, error codes, cautions, maintenance items, fuel usage, fuel levels, DEF levels, ambient conditions and much more.

A powerful Komatsu SAA6D107E-3 engine provides a net output of 143 kW 191 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) systems reduce particulate matter and NOx while providing automatic regeneration that does not interfere with daily operation.

Fluid neutral or better Fuel & DEF total consumption is less than fuel consumed by prior model.

Cooling • Auto-reversing fan is standard • Wider core coolers • Swing out fan

Remote boom and bucket positioners can set kick-outs from inside the cab.

Variable displacement piston pumps with CLSS help reduce fuel consumption.

Rearview monitoring system (standard)

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

HIGH PRODUCTION WITH LOWER FUEL CONSUMPTION

Large capacity torque converter with lock-up: ■ Quick acceleration ■ Lock-up in 2nd, 3rd and 4th gear

Komatsu SmartLoader Logic helps reduce fuel consumption with no decrease in production.
