The Komatsu D51PX crawler dozer sets the standard for general-purpose construction dozers. Built for precise, high-speed grading, the new Tier 4 Final engine and electronically-controlled hydrostatic transmission together burn up to 13% less fuel and remain easy to maintain. In addition, the new PX model, high capacity, high-wear-resistant, HST dozer blade offers up to 15 percent more production. For jobsite applications ranging from golf course construction to highway projects, the Komatsu D51PX is the obvious choice.
