I run two Hustler Super Zs, one with a mulch kit and one with side discharge. The mulch kit unit blows a fine powder out the front anytime the grass and soil aren’t wet(which is a lot lately). That pressure has to escape somewhere. I’ve seen Dixie Choppers running the expanded metal chute blocker and they seem to work well enough. Those leaves are going to keep moving until they either drop out the back or are fine enough to blow through the mesh.
