A grader is a type of rubber-tired road construction equipment having one or two blades with knives.
Typically, self-propelled graders have three wheel axles, the blades may be located between the axles and/or outside of the wheelbase. Control of blade increase and their slope angle in vertical and horizontal planes is conducted from the cab and carried out by power of hydraulics. Moreover, some modern modifications are also equipped with automatic leveling system, which provides more accurate correction of the position of the blade.
Graders are widely used in the construction and road-building sectors, where these vehicles are applied, just like bulldozers, for leveling and grading surface, creating levees, layer-by-layer removal and movement of soil, sand, gravel, etc. Moreover, these vehicles are often involved by the road and municipal utilities to clear snowdrifts.
It should be noted that, apart from self-propelled autograders, there are also rear and front tractor-propelled and semi-trailer graders designed for hitching with trucks, tractor units, tractors and other self-propelled vehicles.
