2024 Komatsu Dozers D71EX-24
Built to offer you outstanding versatilityVersatile enough to accomplish rough dozing to grading, Komatsu’s largest hydrostatic transmission dozer H mode helps operators maintain ground speed while operating under heavy loads. Distinctive slant nose design offers operators exceptional visibility and precision on the job site.
Features may include:
4Outstanding visibility for your operators- Outstanding visibility to the cutting edges and excellent balance and maneuverability with a super-slant nose cab-forward design.
- Smooth, powerful turns with hydrostatic steering. Fully electronic control provides complete automatic shifting and allows for Quick-Shift or variable speed selection.
- In P mode, the engine outputs its full power to help your operator perform heavy-load work. It automatically increases engine speed for maximum power when load increases. H mode increases engine high idle speed, suitable for power-intensive work.
- Flexibility to adapt to various situations and the ability to be efficient and productive regardless of the terrain with a versatile 6-way PAT (power angle tilt) blade pitch system.
- Easy access to the radiator, oil cooler and charge air cooler with swing-up assisted lift system. Hydraulic fan reverses for clearing objects restricting air flow. Rear-mounted single-plane cooling system swings up for fast service.
