A bulldozer is a heavy vehicle used for earthwork and construction. The machine is adapted to moving large amounts of soil, sand, gravel or other construction materials. The main task of the bulldozer is to move and form the terrain, as well as to perform various earthworks such as excavations, embankments, levelling or preparing the ground. Bulldozers are equipped with a special head called a “loader” or a “bucket” placed at the front of the machine.
