Komatsu America Corp. announces the new D51EX/PX-24 crawler dozer
15 percent more productive and 13 percent more fuel efficient, this dozer is a versatile, earthwork and fine-grading all-around performer
LAS VEGAS, March 8, 2017 - Komatsu America Corp., a leading global heavy equipment manufacturer, introduced the new D51EX/PX-24 crawler dozer at CONEXPO-CONAGG 2017 today. Among the most versatile of all the Komatsu dozers, it features an updated, Tier 4 Final engine, and an electronically-controlled hydrostatic transmission. These two features provide up to 13 percent less fuel consumption than the prior model, and exceptional maneuverability, respectively.
Also, the new PX model, high-capacity blade with wear-resistant moldboard, can increase production by 15 percent, compared to the previous model. Additionally, the Standard Parallel Link Undercarriage System (PLUS) offers up to double the wear life, and up to 40 percent less maintenance expense, compared to standard undercarriage designs.
“The D51EX/PX-24 is a versatile machine, at home on jobsites from landscaping to site prep, as well as highway projects where you’re sculpting on and off ramps, for example,” said Jonathan Tolomeo, product manager, Komatsu America. “It can do the nimble jobs required of a small dozer, but also move serious dirt,” Tolomeo said.
