The Caterpillar D9 is a large track-type tractor designed and manufactured by Caterpillar Inc. It is usually sold as a bulldozer equipped with a detachable large blade and a rear ripper attachment. The D9, with 354 kW (474 hp) of gross power and an operating weight of 49 short tons (44 t), is in the upper end of Caterpillar's track-type tractors, which range in size from the D2 69 kW (92 hp), 9 short tons (8.2 t), to the D11 698 kW (935 hp), 104 short tons (94 t). Its size, durability, reliability, and low operating costs have made the D9 one of the most popular large track-type tractors in the world. As 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 construction, demolition, forestry, mining, waste, and quarry operations.
