I did the TNHunter method he calls \"double-rake\". My version is really quadruple raked, tho. and a pounding w/ metal rake to loosen soil around roots...
1] first rake to remove top leaf clutter w/ large fan rake
2] switch rakes, score ground [translate: a pounding w/ metal rake to loosen soil around roots...]
3] sow seed to desired amount/sq ft
4] using metal-tined rake, move seeds into small holes/scores I made in step 2 and rake soil over them
5] switch rakes back to fan rake and recover bed w/ leaf clutter
