Until the introducing of the D10 in 1977 at a dealer meeting, the D9H was the largest conventional bulldozer built by Caterpillar. The size, power and weight of the larger track-type tractors dictate that they are used primarily for major projects. The D9 is most commonly found in use in construction, forestry, mining, waste, and quarry operations.
