Komatsu D51PX-24 crawler dozer is a mid-size tracked bulldozer designed for grading, earthmoving, site preparation, and general construction work. It features a wide PX undercarriage for improved flotation and stability on soft or uneven ground. The D51PX-24 is commonly used in road building, land clearing, utility work, and material spreading. Komatsu equips this model with hydrostatic transmission, responsive blade control, and operator-focused cab design for efficient dozing and finish grading. As a crawler dozer, the D51PX-24 combines traction, maneuverability, and low ground pressure for work in demanding terrain and confined job sites.
