Hydrostatic transmission (HST) control system

The D71EX/PX-24 is equipped with Komatsu-designed HST provides smooth powerful turns. Fully electronic control provides full automatic shifting and enables smooth control. The travel speed can be selected smoothly with the UP/ DOWN switch, and the engine power is maximised in all speed ranges. In addition, a powerful and smooth turn is achieved by controlling the outer track faster and the inner crawler track slower.

Unrivaled Blade Visibility

The D71EXi/PXi-24 incorporates Komatsu’s super-slant nose design. Komatsu’s innovative design provides excellent blade visibility for improved machine control and increased efficiency and productivity.

Next Generation Intelligence

The D71EXi/PXi-24 features improved machine efficiency for work ranging from heavy dozing to finish grading with intelligent Machine Control 2.0 technologies. Lift layer control realises consistent lift layers with automatic control, while proactive dozing control cut and carry work is smooth as if performed by experienced operator.
