I recently got mulch kits for my 36 Stander/48 ZMaster. I am cutting St. Augustine and Bahia and the results have been very good. We are slowing down, but our St. Aug yards are still going pretty good and my Stander cut clean on the first pass. There was a little blowout from the deck, but overall better that side discharge with Gator Blades. The real test will be next summer when we are in full swing with Bahia. Overall though the kits are doing what I wanted, less mess.
