Komatsu America's WA380-8 wheel loader features a 6.69-liter, 191-horsepower Komatsu SAA6D107E-3, variable geometry turbo charged and after cooled Tier 4 Final certified engine and uses up to six percent less fuel than its Tier 4 Interim predecessor, according to the OEM.

Komatsu’s SmartLoader Logic software combines with a lockup torque converter, which activates in second, third and fourth gears. Together, the system is designed to provide optimal engine torque for improved acceleration, hill climbing, a higher top speed and fuel savings.

Komatsu designed the machine’s Komatsu Diesel Particulate Filter (KDPF) and other after treatment components to work in harmony with the engine for efficiency and long life. A Selective Catalyst Reduction (SCR) assembly is incorporated to further reduce NOx emissions using diesel exhaust fluid (DEF). The engine uses an advanced electronic control system to manage the air-flow rate, fuel injection, combustion parameters and after treatment functions to optimize performance, reduce emissions and provide advanced diagnostic capability.

In-cab enhancements and features include:

  • A new, air-suspension, high-back, heated seat designed to soften machine vibrations for operator comfort, and cast frame members for increased strength
  • Seat-mounted electronic pilot control levers with F-N-R switch
  • Pioneering KOMTRAX telematics system and monitor that provides key machine metrics, including KDPF status, DEF-level data, fuel consumption, plus performance information collected and sorted by operator ID
  • Komatsu Auto Idle Shutdown to reduce idle time and save fuel
  • Auxiliary jack and two 12 volt ports
  • A seven inch, full color, high-resolution monitor with ecology guidance
  • A dedicated, full color, seven-inch, rear-view monitor is standard

Additional features:

  • Swing out cooling fan with wider fin spacing and standard auto-reversing fan for ease of cleaning
  • Gull-wing engine doors
  • Full-rear fenders are standard
  • Additional hinged panels at each side of the machine for easy access to regeneration components
