I need a thatcher / power rake. I have looked around at stores.. don't feel like spending over a grand right now because I can't. I can rent one and line up my clients which I will most likely do... $65.00 for 24 hrs. Are attachments for the rear (rock guard) a good way to go? Do they work okay? I would put it on a Honda commercial walk behind, I have two mowers. I heard to check out golf courses, see if they are selling off equipment and they probably take good care of their equipment. Any recommendations?
