Komatsu D51PX-22 crawler dozer is a mid-size tracked bulldozer designed for grading, dozing, and site preparation in construction, roadbuilding, and utility work. The PX undercarriage provides a wider track footprint for improved flotation and stability on soft or uneven ground. The D51PX-22 is typically equipped with a Komatsu diesel engine, hydrostatic transmission, and a power-angle-tilt blade for efficient material control. Its low ground pressure design supports work in muddy, sandy, or sensitive terrain. Common applications include earthmoving, land clearing, finish grading, and general contractor use.
