Apply 1/4″-1/2″ of soil mixture on top of the low areas. Only 1/2” of material can be applied at a time so that you don’t smother the grass; With a push-broom (or leveling rake), work the soil mixture into the grass as thoroughly as possible.It’s best to use a lawn levelling mix of sand, topsoil and organic material to level a lawn.
