Wikipedia says that, depending on its type, a single bulldozer can weigh anywhere from 8 to 104 tonnes. HeavyEquipment.com says that bulldozers with wide tracks can spread their weight over a large area, which makes the pressure less.
Bulldozers by design sport an immense blade and versatile track. The blade is used to move things from one place to another, and the tracks help the bulldozer move over rough terrain and steep slopes. A bulldozer’s diesel engine provides between 50 and 700 horsepower. The cabins of bulldozers can have air conditioning, AM/FM radios, and seats that move on their own.
The Caterpillar D9 is one of the most popular track-type bulldozers in the world because of how cheap it is to run, how big it is, how reliable it is, and how long it lasts.
