New seeding questions

I have about 10 acres in 3 small patches I need to be seeded into hay. Two are old bean fields and one was a hay field that got tore up for a sewer route. I've never planted hay before so I'm looking for the basics on how to get it done. I know it has to be really smooth. How would you go about doing that? I have a disc and an old Vibra Shank. I use a telephone pole for a drag.

The eight acres are old Bean field that weren't planted this year and the two are just bare dirt right now. When and how would you recommend doing it?
