My girlfriends parents want their yard dethatched and over seeded. What is the best way to do this? Their yard is HUGE and i know it will be a big job. They are going to pay accordingly, but i need to know what kind of equipment i need them to rent, and how to go about doing it. I know to dethatch first, then do the seeding second. What is the best way to spread the soil and seed? Or is their another way to do it? I have an exmark 48'' lazer. That's about it as far as equipment. Thanks for the help and advice, I have never done this before.
