I have a yard that is maybe 4-5 acres of field land that was recently turned into a homesite. Before the driveway was put in, we were driving across the ground for some time. Now we have some ruts that make mowing a pain in the back, literally. There are also a few ruts from the power and septic companies, some low spots that I'd like to level and smooth before I start working on seeding. I'm thinking a box blade and just riding around letting the dirt find the low spots. Is there a better way? Speaking of seeding, what would be a good grass for a large area such as this? I would like it to be thick, but slow growing. Right now, its covered in Bahia and I'm mowing twice a week at the peak months. I'd like to rid the yard of the Bahia completely, or at least stifle it. All help is appreciated.
