Komatsu D61PX-23 crawler dozer is a mid-size tracked bulldozer designed for grading, dozing, and site preparation in construction, roadbuilding, and land clearing applications. The PX undercarriage provides a wider track gauge and lower ground pressure than standard models, improving flotation and stability on soft or uneven terrain. The D61PX-23 is typically equipped with a hydrostatic transmission, responsive blade control, and a fuel-efficient Komatsu diesel engine. Common uses include earthmoving, finish grading, and material spreading. Its operator cab is designed for visibility, comfort, and control during extended work cycles in demanding jobsite conditions.
