Efficient fuel consumption mixed with better visibility
Efficient fuel consumption in a mid-size dozer with the updated D61PX-24. This mid-size dozer provides your operator exceptional blade visibility and comes with a parallel link undercarriage system for long undercarriage life.
- Lower ground pressure than D61EX
- Fuel consumption is reduced up to an additional 5% over prior model
Features and benefits
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.
