I've started this process just recently. I'm converting about two acres surrounding the house from former pasture, most recently weeds and sticker burrs. First of all, I plowed everything under, turning it with a Ferguson 14 AO 28 two bottom moldboard that I just found and purchased recently. It did a great job. I'm going to let everything sit there and dry up/rot for a couple of weeks, then I'm going to borrow my friends disk harrow and disk it several times over several weeks, going in different directions each time. By the time I'm done I hope to have a very clean, level seed bed. Then I'm going to add nutrients as prescribed by a soil sample test by the lab at Texas A&M University. Probably will need a couple of tons of lime and balanced fertilizer. Then I will spread my grass seed. Not sure yet what kind of seed. Our county agent suggested straight bermuda. Other folks have said they got a very good lawn from a "golf course mix, mostly bermuda I think, mixed with winter rye." I kinda like that idea.
We're off to a great start after a very wet spring. (Bellville, Austin County Texas, about 70 miles west of Houston.) I hope it keeps up, though I am several weeks away from being ready to plant.
