A bulldozer is a crawler (tracked tractor), equipped with a substantial metal plate (known as a blade), used to push large quantities of soil, sand, rubble, etc., during construction work. The term "bulldozer" is often used to mean any heavy equipment (sometimes a loader and sometimes an excavator), but precisely, the term refers only to a tractor (usually tracked) fitted with a dozer blade.
Most often, bulldozers are large and powerful tracked heavy equipment. The tracks give them excellent ground hold and mobility through very rough terrain. Wide tracks help distribute the bulldozer's weight over large area (decreasing pressure), thus preventing it from sinking in sandy or muddy ground. Extra wide tracks are known as 'swamp tracks'. Bulldozers have excellent ground hold and a torque divider designed to convert the engine's power into improved dragging ability. The Caterpillar D9, for example, can easily tow tanks that weigh more than 70 tons. Because of these attributes, bulldozers are used to clear areas of obstacles, shrubbery, burnt vehicles, and remains of structures.

KomatsuMachines belonging to this category are otherwise called a bulldozer, which pushes earth and rocks with a blade installed at the machine’s front end. Large- sized crawler dozers normally have a set of claws called a ripper that is installed at the machine’s rear end and can crush a hard rock. Swamp bulldozers are equipped with an undercarriage that is configured to enable them to freely move around on a marshy land. As a fellow machine, there is a pipe- laying machine that lays down a large steel pipe in the construction of a pipeline and a dozer shovel (crawler loader) for loading.
