I would like to assist, but I don't have any experience with a groomer (I'm assuming that is what you are referring to). As I understand it, a groomer's job is to stand the grass up for cutting, but I believe zoysia that is healthy and thick does that pretty well on it's own. I may be looking at a jump to a GM this year as well, and I already decided that a groomer isn't important to me in that decision.
