context_page_description: A bulldozer is a large and heavy tractor equipped with a substantial metal plate used to push large quantities of soil, sand, rubble, or similar material during construction or conversion work and typically equipped at the rear with a claw-like device to loosen densely compacted materials. Most bulldozer tractors are continuous tracked, also termed a crawler.
  Bulldozers can be found on a wide range of sites, mines and quarries, military bases, heavy industry factories, engineering projects, and farms.
  The word "bulldozer" correctly refers to only a tractor fitted with a dozer blade. The word is sometimes used inaccurately for other similar construction vehicles such as a front loader.
context_section_description: Bulldozers have been further modified over time to evolve into new machines that can work in ways that the original bulldozer cannot.
  For example, a loader tractor was created by removing its blade and substituting a large-volume bucket and hydraulic arms, which can raise and lower the bucket, thus making it useful for scooping up earth and loading it into trucks; these are often known as a Drott, trackscavator, or track loader.
  Other modifications to the original bulldozer include making it smaller to let it operate in small work areas where movement is limited, such as in mining. Some lightweight forms of bulldozers are commonly used in snow removal and as tools for preparing winter sports areas for ski and snowboard sports.
  
  In an angle dozer, the blade can be pushed forward at one end to make it easier to push material to the side. Nevertheless, the original earthmoving bulldozers are still irreplaceable, as their tasks are concentrated in deforestation, earthmoving, ground levelling, and road carving. Heavy bulldozers are mainly employed to level the terrain to prepare it for construction. The construction, however, is mainly done by small bulldozers and loaders.
