I am a newbie so please bear with me. I would like to get rid of the discharge chute and replace with mulching blades and the cover to close the discharge opening. It seems like their is a slight consensus to go to the Gator blades but I have not been able to find the cover to close the opening. I have seen where people have fabricated this but that is NOT ME. I would rather have a factory type cover to close this. Anyone have any ideas for me? Thanks, Steve.
