The series began in with a prototype tractor called the D9X. Ten D9X prototype models were built in The D9 came equipped with a 1, cid D which powered the D9 right up until the introduction of the D9L.
Over its year life the D9G became the main crawler on many job sites, testifying to its sturdiness and design. In , West Coast businessman Buster Peterson hooked up a pair of D9Gs to pushload the largest wheel tractor scrapers built. The D9H is still the most powerful conventional track-type tractor in company history. The unit featured the same new type of elevated drive sprocket undercarriage as had been introduced on the larger D10 in The elevated-drive-sprocket undercarriage is a modular design.
To repair the machines one breaks down the tracks and pulls the drive sprockets out. As a result, one can pull the powershift transmission out the rear. In , Caterpillar produced their 25,th elevated-drive-sprocket track-type tractor, a D9N.
The L, N, R and T models of the D9 are visually very similar, differing primarily in the design of their internal systems. The D9R has clutch and brake steering, while the D9T has differential steering.
The blade is mainly intended for earthmoving and bulk material handling: pushing up sand, dirt, and rubble. It also can be used to push other heavy equipment such as earthmoving scraper pans, and in military applications, main battle tanks. The dozer blade usually comes in three variants: A Straight Blade "S-Blade" which is short and has no lateral curve, no side wings, and can be used for fine grading. A Universal Blade "U-Blade" which is tall and very curved, and has large side wings to carry more material.
A "S-U" combination blade which is shorter, has less curvature, and smaller side wings. This blade is typically used for pushing piles of large rocks, such as at a quarry.
Like many other bulldozers, the D9 can be fitted with other devices such as mine plows. The rear ripper is intended for use in loosening rocky ground and ripping out larger stones. It can also break frozen ground and excavate small ditches. The ripper can be replaced with a multi-shank ripper, allowing the bulldozer to comb the ground. 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. Its armor allows it to work under heavy fire. D7G bulldozers are still very common in US combat engineering battalions, but there is a series of oft-recurrent suggestions to replace the lighter D7Gs with the newer and more heavily armored D9s. Many of the D9 operators are reservists and veterans, which operated heavy equipment also as civilians. The IDF Caterpillar D9 gain notoriety during the Second Intifada — when it was used to clear improvised explosive devices and booby traps , and also to demolish Palestinian structures.
The Israeli armor makes the D9 impervious to machine gun and sniper fire and to explosive charges and heavy roadside bombs. A incident involving an IDF Caterpillar D9 in which a year-old American activist was killed resulted in a federal lawsuit against Catepillar, Inc. Today the D9 is one of the main combat engineering tools of the IDF and is considered a valuable asset.
