Graders are multipurpose
machines used primarily for general construction and maintenance of roads and runways,
machines used primarily for general construction and maintenance of roads and runways,
moving large amounts of materials like soil ,snow laterally by side casting.
Moldboard: it is also referred as blade. Used for side cast the material it encounters .its ends can be raised or lowered. it can be placed in may position.
l Frame : the frame connected to the front axle extends the full length of grader and enhances the mechanism.
l Scarifier : material too hard to cut with the moldboard are broken with the scarifier.
l Circle : the circular shape beneath the frame allows the moldboard to position at any angle.

Different Tasks of a grader:
1) Planning surface: Mold board can be set at any angle to plane off irregular surfaces and using the resultant material to fill low spots.
2) Ditch cuts: Ditches can be cut by moldboard and scarifier combined normally at 2nd gear at full throttle.
3) Creating a bank slope: Grader can be used for Sloping the bank of road prevents slope failure.
4)Cleaning Ditches: Grader can be used to remove unwanted material from ditch during the bank slope operation.
5)Spreading material: Graders are often used to spread and mix loads.
l Capacities
Different capacities of grader ranges from
about 60 to 600hp.
Blade size ranges from 2.5 to 7.3 meter.
