"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. Angle: A type of blade, typically only 4' in height, that attaches to the dozers C-frame.Straight ("S-Blade") which is short and has no lateral curve, no side wings, and can be used for fine grading.The dozer blade on front of the tractor usually comes in 4 varieties: The Egyptian Army operates an unknown number of armored D7R II. 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. This 235 hp (175 kW) D7E comes with a diesel-electric drive system powered by a 537cid C9.3 diesel engine. In March 2008, at Conexpo 2008 held every 3 years in Las Vegas, Caterpillar introduced the D7E.
