Komatsu Powertrain

Komatsu Powertrain components are critical to the high levels of performance, production, efficiency and reliability of your Komatsu equipment. In machines where the efficient delivery of engine power to the ground is essential, such as dozers, graders and wheel loaders, we have developed unique and unrivalled transmission technologies delivering industry-leading responsiveness, speed, and durability.


These include our Torque flow powershift dozer transmissions, our dual powershift/lockup Torque Converter Auto grader transmissions, and fourth-generation hydrostatic drives on our wheel loaders. These combine with Komatsu final drives and differentials to efficiently convert torque to traction, ensuring your Komatsu machine operates productively under the most challenging ground conditions encountered on NZ jobsites. And with all Komatsu powertrain elements designed and manufactured to work together with optimum efficiency, it’s critical that you use genuine Komatsu components, parts, consumables and lubricants to continue getting the best from your machines.
