It is equipped with the new generation engine which meets emission regulation in Japan, North America and Europe.

In addition, it achieves a high level of productivity and mileage performance by adopting the new engine control system "Komatsu smart loader logic" with a large-capacity torque converter, a wide range lock-up clutch and automatic kick down which facilitates reduced fuel consumption.

Equipped with the new rear view camera monitor and the new large size pillarless ROPS cab which increased the glass area of the lower front, safety and visibility have been significantly improved.

It employs the 7-inch HD LCD monitor in the operators cab which ensures safe, accurate and smooth operation as well as supports energy efficient operation while integrating with the eco-guidance system.

Bulldozer OPEN

Since its first emergence in 1951, it took only 50 years for the hydraulic shovel to establish its primary position on construction sites worldwide. Its size ranges from mini to super size depending on the scale of construction, and during the half century, it kept evolving by achieving a minimum rear-swing radius and adapting styles that would work with characteristics of each site. Mirroring the movement of a human hand, a hydraulic shovel will continue to evolve during the 21st century.
