Komatsu recently introduced the D71EX-24/PX-24, a crawler dozer that the company says is the most powerful hydrostatic transmission (HST) model in the midsize class. Featuring a slant-nose front design, the dozer is adept at grading, pushing, side-cutting, and working on softer ground, Komatsu says, allowing operators to transition from production to finishing work with the same machine. The dozer joins 15 other models in Komatsu’s midsize range, which includes dozers that specialize in intelligent operation and waste handling.

Power & To Spare

The D71EX-24/PX-24 is Komatsu’s biggest HST dozer, with an operating weight that ranges from about 50,000 to 53,000 pounds (22,680 to 24,040 kilograms) depending on the configuration. The dozer’s high-capacity, wear-resistant blade has 6.1-cubic-yard (4.7-cubic-meter) capacity. The dozer’s four-cycle, water-cooled, direct-injection Komatsu SAA6D114E-6 engine generates 237 horsepower (177 kilowatts) at 2,000 rpm. Komatsu notes that the machine can maintain ground speed while taking on heavy loads in H mode. Travel speed tops out at 6.8 mph (11 km/h).

All This & Brains, Too

The D71i-24 variant comes equipped with Komatsu’s intelligent Machine Control (iMC) 2.0 technology that provides such blade and bucket abilities as automatic bucket angle, tilt bucket, lift layer, and tilt steering control. iMC 2.0 also enables quick temporary surface design and proactive dozing control, the latter of which helps less experienced operators cut and strip from existing terrain automatically. Komatsu makes iMC available in numerous dozer and excavator models.
