How do you level a lawn?

Topdressing is a great way to level a lawn.  Applying a thin layer of sand or soil can help level the lawn.  Be sure not to apply too much depth at one time if applying on top of an established turf grass.  Use the back of a rake or a broom to smooth out the material in small areas.  For large topdressed areas, use a drag or a type of smoothing device (old fence, heavy board, etc.) to smooth out the topdressing sand.
