I considered teeth as well but was advised against it on a small tractor. I was told that it encouraged doing a bit too much for the tractor to handle. I'm not sure whether that is correct or not, but I figured I could add the teeth later if I found that I really needed them. I haven't had my tractor long enough yet to see if I really need teeth, but it's done all I've asked it to do.
