Thanks for the reply, Riggle.
First, I meant to say Tenacity instead of dimension. Sorry about that!
2nd, My initial thought was just a major overseed with a slit seeder then I started thinking about doing some site work to deal with drainage issues. My question regarding the power rake was regarding if it loosens enough dirt to fill depressions cut drainage lanes. I assumed that the power rake was similar to a Harley rake?
As far as the seed goes, I know that it is about 60% falcon IV. I cannot remember the other 2 cultivars, but they were names that I recognized.
