In the 1974 TV movie Killdozer! a D9 was used instead.First introduced in 1935 as the RD8, this tractor was immediately popular for its balance of size and power. Various other blade types are used including landfill U-Blades, woodchip U-blades, and two-way blades for work inside the holds of ships.Ĭat D7 with crane option, 1943 In popular culture Ī WW-II era Caterpillar D7 is the main antagonist in the novella Killdozer! by Theodore Sturgeon. "S-U" combination blade which is shorter, has less curvature, and smaller side wings.Universal ("U-Blade") which is tall and very curved, and has large side wings to carry more material.Most commonly found in pipeline construction, due to the fact that an experienced operator can move and grade large quantities of material in a relatively short amount of time. The C-frame has 3 holes on each side where the blade will be manually pinned into, thus the angle blade has 3 set positions: right angle, left angle, and centered.

The United States Marine Corps replaced its fleet of D7Gs with John Deere's 850J MCT in 2009. Later, the US Army developed a remote controlled version of the D7G for mine-clearing applications. The armor was developed by the Israel Military Industries (IMI). The US Army used armored D7G to clear mine fields and unarmored D7G and D7H for earthworks. Specially modified D7E's fitted with Rome plows were used to clear forest in the Vietnam war. This makes it ideal for working on very steep slopes, in forests, and for backfilling pipelines safely without risking damage to the pipe.Īn agricultural version without the blade and rippers is commonly used by farmers. The vehicle is powerful, yet small and light (16 to 20 short tons ) depending on configuration). It is primarily used to move material short distances or through challenging terrain.

The C9.3 powers a generator that turns out electricity that supplies power to a pair of AC drive motors.

In March 2008, at Conexpo 2008 held every 3 years in Las Vegas, Caterpillar introduced the D7E. The high-drive design returned in 2020 with the introduction of the D7 (forgoing a generational letter under Caterpillar’s new naming system). The electric drive D7E entered service in early 2009, returning to a traditional ‘flat-track’ configuration for this iteration only. The D7R replaced the D7H in 1996, followed by the D7R Series 2. In 1986 the 215 hp (160 kW) D7H was the first D7 equipped with Caterpillar’s elevated drive sprocket undercarriage.
