I've used mulching kits and I've used Gator blades.... but not a mulching kit on a Raptor. Mulching kits can work really nice but you have to realize your grass has to be dry and you must like to cut at a little higher cutting height to hide the clippings and keep air flowing ... and you need to cut a little more often. What is really nice about a mulching kit is that you don't have clippings flying all over the place and these decks with high lift blades and even gator blades can tend to throw them pretty far. And you'll now have a trimming Edge on both sides of your deck.
