I never had very good luck broadcastin fescue even when we'ld grazed it to the dirt. Any kind of drill that will handle grass seed will work. A no-till may be ideal but I've had excellent success with my old VanBrunt. It will atleast get the seed to the surface or slightly below.
With that out of the way, if you can lightly disk it preferably with the blades set straight you may be able to roughen the soil enough that seed can make contact. My standard rate for fescue through the drill is 10 pounds an acre into existing pasture. I would probably triple that for broadcasting.
If you bring it up to soil test and hammer the existing stuff, unless it's really totally TU, with nitrogen you'ld be surprised at how well it comes back.
