  Bulldozer is a powerful, motorized machine equipped with a front metal blade for pushing materials such as soil, sand, snow, rubble, or rock in construction and earthmoving projects. Most bulldozers run on continuous tracks, while some models use large off-road tires. A common rear attachment is the ripper, used to break up hard ground. Bulldozers are widely used in construction, road building, mining, agriculture, heavy industry, and military operations.
