If your seeding is going to be a Turf or Lawn type grass,I normally spread starter fertilizer and work it in about 1"-2" deep.This gives your new seeding something to "root down" to.I then take that old set of metal bed springs and drag in 2 or 3 directions to get the "fine" seedbed.Then I broadcast the seed and drag it in with the bed springs enough to cover most of the seed.Your seed does not want to be too deep.
After the grass germinates and starts growing,I will come back and spread a top dressing of fertilizer,to give it a "kick".I always try to fertilize in the Fall,as the roots will continue to grow even though the Winter months.
Good luck,hopfully Mother Nature will give you a hand,seems like sometimes it takes FOREVER to get an established lawn.
