Aeravators work best on very dry soil. Not so good on wet soil. When the soil is dry, it will shatter the soil to allow greater root growth. Greater meaning deeper. The down side of this, it really allows the soil to dry out at a much quicker rate than a coring aerator. So irrigation, rain is a plus. When using on wet soil, it basically wallers out a hole, compressing the soil around it, creating what you are trying to alleviate. For over seeding, some aeravators have seed boxes attached. If no seed box, spreading seed with a cyclone spreader or any spreader for that much, then running the Aeravator over it. Works great. On bare dirt, same procedure. For best results, the slower the better. I run an 80” on a John Deere 3046. Front weights are definitely suggested as these are very heavy. The rear roller can be adjusted to control depth. Also a hydraulic top link is useful to control depth as well. Hope this helps. I use mine on athletic fields as well as homeowner lawns. You can really feel a difference between an areas that you have been over and the ones you have not.Typically, I core aerate in the spring because it is wet, use the Aeravator during other times when it is dry. Hope this helps. Yes, I love mine.
