Now with a new technology Komatsu engine, our intelligent Machine Control (iMC) D61EXi/PXi-24 Komatsu 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.
Resources
Features and benefits
Improved machine control efficiency
Up to 8% more efficient dozer operation that typical aftermarket machine control systems with Komatsu's intelligent machine control. This is in addition to the substantial savings standard machine control already offers over manual staking and grading.
Unrivaled blade visibility
The D61EXi/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.
Comfortable working space
The D61EXi/PXi-24'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.

Tier 4 engine KDPF regeneration
As the technology of diesel engines has progressed from Tier 3 to Tier 4 Final, design aspects of the engines have been fine-tuned to comply with regulations to cover regulated diesel engine exhaust pollutants.
The result is that these new diesel engines are cleaner than ever before, and in many cases more fuel efficient too. Along with this comes the need to properly manage and maintain these new generation of machines to make sure that operating costs are minimised.
Hydrostatic transmission (HST) control system
The D61EX/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.
