very interesting idea. I always aerate, seed then fert in that order. I seem to think that using my ride on to fert will help with soil contact. Interested in the seeding then aerating method. I always thought the tines may destroy or break some seeds, but guess it isn't enought to tell. But also wanted some of the seed to fall in the aeration holes. If your test holds and we only need aeration holes of 1-2 inches or less that could speed things up. I have a lawn solutions ride on and could do more passes at 1 inch deep than 3 inches deep due to equipment wear and tear. Keep us updated.
