Achieve efficient fuel consumption with the updated D61PX-24 mid-size dozer. This machine offers your operator exceptional blade visibility and features a parallel link undercarriage system for extended undercarriage life.
- Lower ground pressure compared to D61EX
- Additional up to 5% reduction in fuel consumption over the prior model
Product Features and benefits:
- Even Wear Design: The PLUS undercarriage system is meticulously designed to wear evenly, ensuring that the machine provides close to 100% usage of undercarriage components. This feature significantly contributes to extended component life and operational efficiency.
- Cost-Effective Maintenance: Komatsu PLUS undercarriage is engineered to lower undercarriage maintenance costs by up to 40% compared to conventional undercarriage systems. This cost-effective design benefits owners and operators by reducing the overall cost of ownership.
- Enhanced Wear Life: Strengthened rollers and links within the PLUS undercarriage system contribute to increased wear life, providing durability and reliability in various working conditions. This enhancement results in wear life up to two times longer than conventional undercarriage systems.
- Power Angle Tilt (PAT) Dozer Blade: The PAT dozer blade with adjustable blade pitch system offers versatility in a variety of applications. It enables operators to optimize the blade’s angle for different tasks, expanding productivity and enhancing the machine’s overall performance.
- Exceptional Blade Visibility: The innovative super-slant nose design ensures exceptional blade visibility. This feature enhances machine control, allowing operators to work with precision and efficiency. Improved visibility contributes to increased overall productivity.
- HST with Electronic Control: The fully electronic control of the Hydrostatic Transmission (HST) system provides complete automatic shifting and enables smooth control. Equipped with Komatsu-designed HST, the machine allows for Quick-Shift or variable speed selection, enhancing operational flexibility.
- Easy-Access Maintenance Features: The PLUS system incorporates easy-access maintenance features for efficient serviceability. A swing-up fan with a gas strut-assisted lift system provides convenient access to the radiator, oil cooler, and charge air cooler. The hydraulic fan includes a reversing function for cleaning any objects that may restrict airflow.
- Palm Command Control System (PCCS) Joystick: The PCCS joystick is designed for operator comfort and ease of use. Its ergonomic, low-effort design allows control over all directional movements, including machine travel speed and counter-rotation. This enhances operator control and reduces fatigue during extended work periods.
