  • Swift and responsive in a compact size
  • Exceptional blade visibility
  • Rapid steering and reliable balance

Parallel Link Undercarriage System (PLUS): The Komatsu PLUS undercarriage system is meticulously designed to wear evenly, ensuring close to 100% usage of undercarriage components. This innovation significantly lowers undercarriage maintenance costs by up to 40% compared to conventional undercarriage systems. The inclusion of strengthened rollers and links further extends wear life, providing durability that surpasses standard systems by up to two times.

PAT Dozer with Adjustable Pitch: Elevate your productivity and enhance versatility across various applications with a Power Angle Tilt (PAT) dozer blade featuring an adjustable blade pitch system.

Exceptional Blade Visibility: The innovative super-slant nose design of the machine ensures exceptional blade visibility. This feature not only improves machine control but also enhances overall efficiency and productivity.

HST with Electronic Control: Fully embracing electronic control, the Komatsu machine offers complete automatic shifting and enables smooth control. The specially designed Hydrostatic Transmission (HST) allows for Quick-Shift or variable speed selection.

Easy-Access Maintenance Features: Facilitating convenient maintenance, the machine incorporates a swing-up fan with a gas strut-assisted lift system. This design provides easy access to essential components such as the radiator, oil cooler, and charge air cooler. Additionally, the hydraulic fan includes a reversing feature for efficient cleaning of any objects obstructing air flow.

Palm Command Control System Lever: Prioritizing operator comfort and ease of use, the machine features an ergonomic, low-effort Palm Command Control System (PCCS) joystick. This control system efficiently manages all directional movements, including machine travel speed and counter-rotation.
