D61EXi/PXi-23 Dozers

Our intelligent Machine Control (iMC) D61EXi/PXi-23 Komatsu bulldozer – available in both standard and low-ground-pressure configurations – incorporates a unique fully integrated blade control system. This allows 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.

For a safer entry and exit – and maximum operator protection, the D61EXi/PXi-23 includes numerous hand-rails and access steps both inside and outside the cabin.

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

Highly efficient hydrostatic drive line

The hydrostatic drive line is a key factor in the performance of the D61EXi/PXi-23 dozer. It supplies high drawbar pull when needed and a highly fuel efficient drive line for grading and precision work. With a choice between two operating modes, the operator can select either “quick-shift” or “variable speed” to match a complete range of applications in the most economic and easy way.

Unrivaled Blade Visibility

The D61EXi/PXi-23 incorporates Komatsu's super-slant nose design. Komatsu's innovative design provides excellent blade visibility for improved machine control and increased efficiency and productivity.

Comfortable Working Space

The D61EXi/PXi-23's cab mount uses a cab damper system and provides shock and vibration absorption conventional mounting systems cannot match. The Silicon-oil-filled cab damper mount helps to isolate the cab from the machine body, suppressing vibration and providing a quiet, comfortable operating environment.
