I have been using the zrators going into my third season. I have one mounted on a toro grandstand. Yes it does well as far as depth of the cores. I have had no issues myself. You are right it is easy to get around the gap. We X our properties and find it still takes less time than other types of aerators. I know some guys who run it on their wrights and they say they are very happy with theirs. Hope this helps!!
