New Komatsu D61EX-24 Bulldozer for Sale

Versatile to accomplish any task, the D61EX-24 brings excellent visibility to all your projects. The second-generation mid-size dozer comes with a new H mode that helps operators maintain ground speed while operating under heavy loads.

  • Next step up in size
  • Can step in for some heavier dozing
  • Fuel consumption is reduced up to an additional 5% over prior model

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.
