Komatsu introduces D71-24 mid-size dozer

Komatsu’s D71EX/PX-24 dozer has a slant-nose design and pushes with 237 horsepower

With a distinctive slant-nose design and 237 horsepower, Komatsu’s new D71EX/PX-24 dozer is among the most powerful hydrostatic transmission (HST) dozers in the mid-size class.

The manufacturer said the earthmover – Komatsu’s largest HST dozer, ranging from 49,824 to 50,927 lbs – is effective at grading, pushing, side-cutting and working on soft ground.

The D71-24 joins Komatsu’s family of mid-size dozers ranging from 40,830 to 56,337 lbs operating weight. There are now 16 models in the class. 

The size and power combination helps operators maintain ground speed while operation under heavy loads in H mode, Komatsu said, and the slant-nose design improves visibility to the cutting edges.

According to the company, the D71-24 is “an all-around dozer” and can handle job sites including golf course construction and highway projects.

The new model is available with Komatsu’s Machine Control 2.0 capabilities such as lift layer control, tilt steering quick surface creation and proactive dozing control, which help optimize productivity, the manufacturer said.

The D71PXi-24 made its global premier at CONEXPO-CON/AGG last March. According to Derek Morris with Komatsu America Corp., the model offers increased versatility and ease of operation.

“Customers say they want this size class dozer to be a ‘Swiss army knife.’ And with our patent-pending features that let you go from grass to grade, it delivers both high production and finesse,” he says.

This latest dozer release comes months after Caterpillar introduced its highly customizable, large-size Cat D9 Dozer in September 2020.
