For years I switched my LX176 38" deck back and forth from non-mulching to mulching kit. I finally took off the mulching baffle and left it as a plain jane 38" deck with high lift blades about ten years ago. As I recall, taking the outlet baffle assembly off was all that was required to return to normal deck mode. I later took the mulching blades off for high lift blades as I pull a Jrco bagger cart during leaf season. Last year I put Meg-Mo blades on the deck and it provided equivalent mulching effect to the original Tri-Cycler kit without clumping. It also chopped-up the tree leaves during leaf season to where the Jrco was holding about 40% more leaf matter. This was a big help.
