I need to correct my previous post. The new steel closing wheel arms do NOT provide sufficient gap between the poly spiked wheels. I've switched over to Mohawks which allow me to get within the 2.0 - 2.5" recommended by Schaffert (will be 2 1/8 -2 1/4" as measured from the point where the plastic hub meets the steel Mohawk ring). Lesson learned should have just upgraded to the new cast arms but I think I'll be happy with the Mohawks. If it ever dries out enough to plant.
