A grader is a construction machine used to level and shape the terrain by moving, removing or adding material. It is a tool used in earthworks, especially when preparing the terrain for the construction of roads, squares or other structures. It is equipped with blades or knives that move through the surface, allowing for the removal of excess soil from higher areas and adding it to lower areas. Usually the depth of cutting or laying can be adjusted, allowing them to adapt to the specific requirements of the project. They are mechanically or hydro-mechanically driven and equipped with wheels or tracks, which affects their mobility and ability to move on various surfaces.
