If mulching grass I've found the clippings usually just plug up any hole small enough to restrict their flow, but when mulching leaves the air will blow out from under the front of the deck blowing the leaves away before you can mulch them unless you have holes in the plug to let the air flow through. Dead leaves are dry and brittle so they usually won't plug the holes.
Like minds man. I dig your homemade mulch plug. :thumbsup:
