Types of bulldozer:A bulldozer is a powerful and heavy vehicle that is used to push dirt, sand, and other materials. There are many different types of bulldozers, each designed for a specific purpose. The most common type of bulldozer is the track dozer, which is equipped with large tracks that provide excellent traction and stability. This type of dozer is often used in construction projects where there is a lot of excavating to be done. Wheeled dozers are also quite popular, as they are more maneuverable than track dozers and can be used on a variety of terrain types. Bulldozers are also equipped with a variety of attachments, such as blades and rippers, that can be used to perform different tasks.
