I've been out of this game for a little over a year now. Mostly did dethatching but I did have an old drum aerator I used once in awhile but it ended up with too many problems to use. I'm thinking of firing things back up this spring as my job is a total joke with seriously low pay and no benifits. I wouldn't mind getting an aerator but I don't want to kill myself using one. I'd like one thats somewhat fast and easy to use. I can't seem to find the website on Lawn solutions but that duel hydro seems like a great concept. I'm also not looking to spend many many thousands of dollars either so that one might not work.
