I'm with way95 on this... mow if you can, if not you only have a few options...
If the rocks are not too big or to many you might try removing them. Or
you can top dress the area with a sandy loam, apply a thin layer every couple wks until they are covered and smoothed out for mowing... Unfortunately some places just seem to 'grow' rocks, and you will have to keep doing this periodically.
If all else fails Heavy Equipment ...:biggrin:... excavate the top and replace with some rich dirt an' replant... :smile:KennyV
