The 191-horsepower WA380-8 wheel loader has a Tier 4-Final Komatsu SAA6D107E-3 engine that uses up to 6 percent less fuel than its Tier 4-I predecessor, Komatsu says. Operating weights range from 40,532 to 40,929 pounds, with bucket capacities between 3.5 and 4.3 cubic yards.

SmartLoader Logic engine-control software combines with a lockup torque converter, which activates in second, third and fourth gears. According to Komatsu, the system optimizes engine torque to match the application for improved acceleration, hill climbing, a higher top speed, and fuel savings.

A new air-suspension seat provides support and dampens machine vibrations, Komatsu says. The Electronic Pilot Control lever console is integrated into the seat, moving with the seat. A secondary F-N-R switch has been built into work-equipment lever configurations.

A dedicated full-color monitor provides the operator with a rear view, and can be set to be on continuously or only when in reverse.

Bucket angle and remote boom positioner can be set from inside the cab. Both upper and lower boom positions are adjustable. The bucket positioner can be set for three horizontal positions, giving the operator flexibility if using different attachments.
