So, a friend of the family asked me and two other buddies to "renovate" their lawn. The task consists of replanting new grass and leveling a few small areas that have some unevenness, nothing too bad. The entire area of lawn is 2-3 acres. We thought the best way to do this job, since they wanted ALL NEW GRASS, since it was alot of weeds, would be to kill the grass with some kind of round-up,using a sprayer pulled by a tractor/atv/etc, then rent a 5 ft comerical tiller for a 30-40hp tractor and till the entire lot, then compact the soil with a roller, then spread grass with a seeder pulled by a tractor/atc/etc then finally cover with a light coating of straw. Please tell me if this is a good plan for this kind of job or not. If you don't think this is a good idea, please tell me what you would do...but i don't have access to expensive hydro seeders and other equipment like that, just the general equipment mentioned. Thank you any advice will be appreciated.
