Top Features

Machine Performance

Up to 10% increased productivity with Komatsu bucket that has higher fill factors and shorter cycle times.

The Komatsu bucket features a new profile which allows for better material flow into the bucket for easier filling.

Large Capacity Lock-up Torque Converter provides quick acceleration and automatically engages in 2nd, 3rd, and 4th gear, requiring no action from the operator.

Automatic Digging System performs bucket curl and boom lift during digging to reduce operator fatigue and help optimize bucket fill factors.

Powerful Komatsu SAA6D140E-7 Tier4 Final engine uses advanced engine timing for higher performance and reduced emissions.

Ultimate Efficiency

Dual work modes allow the operator to select between Power and Economy modes to optimize the machine efficiency and performance to match the application.

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

Fuel consumption is reduced by up to 5% compared with the WAS00-7.

Standard Auto Idle Shutdown helps reduce fuel consumption by automatically turning off the loader at the set time interval.

Komatsu Quality

All major hydraulic and power train components (engine, transmission, pumps, cylinders, etc.) are designed and manufactured by Komatsu which helps increase efficiency and performance by working together in harmony.
