D71EXi/PXi-24 Dozers

Now with a new technology Komatsu engine, our intelligent Machine Control (iMC) 2.0 D71EXi-24 bulldozer – available in both standard and low-ground-pressure configurations – incorporates a unique fully integrated blade control system, allowing it to carry out both bulk and final trim dozing in automatic from start to finish with final grade performance. This significantly increases productivity and efficiency while reducing the cost of each metre of material moved.

The D71EXi/PXi-24 dozer offers the most horsepower in its class and large capacity PAT blade to increase productivity on the jobsite. Hydrostatic Transmission (HST): Grading and pushing applications are improved by greater control and consistent power delivery

Information and communication technology (ICT): 

• Large multi-lingual high resolution Liquid Crystal Display (LCD) monitor 

• Multi-monitor with troubleshooting function to minimise down time 

• Energy Saving Operation Ecological operation report for assistance

And it comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.

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.
