Think You Can Drive a Bulldozer?
Fearing Shortage of Skilled Operators, Machinery Makers Add Auto-Pilot Technologies
JAMES R. HAGERTY

As experienced bulldozer drivers retire, heavy equipment manufacturers are including technology in new models to make precise earth-moving easier. This Komatsu bulldozer has a ‘machine control’ system that uses GPS to program movements around a work site.

Typing I can do—blindfolded, if necessary. But mechanical flair has always eluded me. I recently had to ask a neighbor to help me start a lawn mower. Even so, Komatsu assured me that technological advances would allow me to learn the basics of dozing in a couple of hours. Dozers are used to smooth ground for roads and runways or shape the contours of building sites and golf courses. They are among the trickier types of heavy machinery to operate because drivers must shave huge mounds of earth to precise contours, often while perched on hillsides or mired in mud. Unlike excavators, dozers typically are in motion as they move earth. Read more of this post
