Hey i was just wondering what is a better service to offer? Aerating or power raking/dethaching? What is better for the lawn? I am looking into buying either a aerator or power rake for this fall and next fall. I seem to be finding good deals on both new and used machines at this time of year. So what do you guys recommend? What brands? Has anyone ever tried putting a "dethaching blade" on their regular lawn mowers? thanks!
