Demolition Bulldozer At Urban Renewal Construction Site Royalty-Free Stock Photo

A bulldozer is a large and heavy tractor equipped with a substantial metal plate, known as a blade, used to push large quantities of soil, sand, rubble, or other such material during construction or conversion work and typically equipped at the rear with a claw-like device, known as a ripper, to loosen densely compacted materials. It is usually a crawler tractor. Bulldozers can be found on a wide range of sites, mines and quarries, military bases, heavy industry factories, engineering projects and farms. The term `bulldozer` correctly refers only to a tractor usually tracked fitted with a dozer blade.
