For those thinking about the optional Gravely discharge cover, I bought one and installed it. You remove the discharge chute and a small baffle held by two screws to install the discharge cover. I tried it and like it for the most part, especially because it reduces the width of the deck since the chute is removed. Where I have lush green grass, the clippings pretty much stay where they are cut. But for drier grass and areas that have sparse grass, it creates a lot of clippings and dust flying about on me and the mower. So I decided to remove the discharge cover and return to the chute. May consider a mulching kit if I read positive feedback about it.
