New Komatsu D39PX-24 Bulldozer for Sale

Excellent blade visibility meets operator comfort in the D39PX-24. The PX crawler dozer is ideal for grading or earth moving projects with reduced ground pressure for better balance and an additional fast-blade mode for improved high-speed grading.

  • Nimble size with quick response
  • High blade visibility
  • Quick steering and balance

Parallel Link Undercarriage System (PLUS): Designed to wear evenly so the machine provides close to 100% usage of undercarriage components, Komatsu PLUS undercarriage lowers undercarriage maintenance costs by up to 40% over a conventional undercarriage. Strengthened rollers and links increase wear life up to two times.

PAT dozer with adjustable pitch: Expand your productivity and gain more versatility in a variety of applications with a power angle tilt (PAT) dozer blade with adjustable blade pitch system.

Exceptional blade visibility: An innovative super-slant nose design provides excellent blade visibility for improved machine control and increased efficiency and productivity.

HST with electronic control: Fully electronic control provides complete automatic shifting and enables smooth control. Equipped with Komatsu-designed HST, this machine allows for Quick-Shift or variable speed selection.

Easy-access maintenance features: A swing-up fan with a gas strut-assisted lift system provides easy access to the radiator, oil cooler and charge air cooler. The hydraulic fan has a reversing fan for cleaning any objects that are restricting air flow.

Palm command control system lever: Designed for your operator’s comfort and ease of use, the ergonomic, low-effort palm command control system (PCCS) joystick controls all directional movements, including machine travel speed, as well as counter-rotation.
