The D39PX-24 combines excellent blade visibility with operator comfort, making it an ideal choice for grading or earthmoving projects. With reduced ground pressure for better balance and an additional fast-blade mode for improved high-speed grading, this PX crawler dozer offers:
- Nimble size with quick response
- High blade visibility
- Quick steering and balance
Product Features and benefits:
Advanced Undercarriage System (PLUS)
The PLUS undercarriage system is made to wear evenly, ensuring nearly 100% utilization of undercarriage components. Compared to traditional undercarriages, Komatsu PLUS lowers maintenance costs by up to 40%. Strengthened rollers and links also extend wear life up to two times.
Adjustable Pitch PAT Dozer
Enhance productivity and versatility in various applications with a power angle tilt (PAT) dozer blade featuring an adjustable blade pitch system.
Improved Blade Visibility
The innovative super-slant nose design enhances blade visibility, improving machine control, efficiency, and productivity.
Electronic Control HST
Experience fully automatic shifting and smooth control with electronic control High-Speed Transmission (HST). The Komatsu-designed HST allows for Quick-Shift or variable speed selection.
Convenient Maintenance Features
Accessing essential components is made easy with a swing-up fan using a gas strut-assisted lift system. This provides easy access to the radiator, oil cooler, and charge air cooler. The hydraulic fan also has a reversing function for cleaning any objects hindering airflow.
Palm Command Control System Lever
Designed for operator comfort and ease of use, the ergonomic, low-effort Palm Command Control System (PCCS) joystick manages all directional movements, including machine travel speed and counter-rotation.
