Answer: What you propose is one way to renovate a lawn, but you might be able to get it into shape without that much work. If it's weedy, use a weed and feed fertilizer. Then rake out the dead patches and overseed the entire lawn with fresh seeds. Keep the lawn well watered and mowed at the right height and plan on feeding it 4 times a year. If, in the fall, it still doesn't look terrific, you can rent an aerator which takes plugs out of the soil. Leave the plugs on the ground (they will dissolve with the rain and water from the sprinkler). Then spread a thin layer of sand over the entire lawn. The sand will work its way into the holes where the plugs of soil came out and the sand will help loosen the soil and make it easier for the grass roots to take hold.
Best wishes with your lawn!
