Overview
The Komatsu D39PXi-24 is a versatile dozer engineered for both heavy site preparation and precise finishing work. Powered by a fuel-efficient EPA Tier 4 Final / EU Stage 4 certified engine, it offers a quiet, comfortable ROPS/FOPS cab with excellent blade visibility. Integrated Komatsu Intelligent Machine Control (IMC) 2.0 optimizes grading accuracy and productivity while advanced hydrostatic transmission and full-power track control deliver strong maneuverability.

Key product benefits

• Rapid onboarding for new operators with automated assist functions
• Faster progression from rough excavation to finished grading
• Seamless integration of 3D design data into machine workflows
• Consistent layer spreading and repeatable results across passes

Features and benefits (selected)

• Learns as it works — Proactive dozing control records terrain and adapts subsequent passes to improve productivity versus previous generations.
• Automatic layer spreading — Lift layer control enables operators to spread fill to consistent layer thicknesses with a single command for improved compaction quality.
• Stable leveling in rough dozing — Tilt steering control adjusts blade tilt to maintain straight travel and reduce steering corrections during heavy work.
• Quick surface creation — Temporary design surface can be created on-board to begin automated stripping or spreading before final models are available.
• Close the operator skill gap — Machine logic learns blade inputs and supports less experienced operators with calculated adjustments for better finish results.
• Advanced machine control — Auto-stripping, auto-spreading and finish grading automation reduce operator workload and increase repeatability, even without an external 3D model.
• Outstanding blade response — IMC anticipates grade transitions and adjusts blade angle for superior finish grading.

Technology

• Komatsu Intelligent Machine Control (IMC) 2.0: includes quick-design creation, tilt steering control and lift layer control to support automated, consistent spreading and high-production dozing.
• Integrated IMC supports auto-stripping, auto-spreading, high-production dozing and finish grading while continuously learning terrain and adapting machine behavior.
