Sooooo.....maybe the OP needs to try some OEM hi-lift blades, right?
P.S.
I'm gonna try to attach some pics of my Gravely deck "before installing the mulch kit" and "after installing the mulch kit" so the OP can compare to what the "mulch kit" installed on his ZTR looks like in comparison(design-wise). If I can just get the attachments to cooperate:0) BTW, you can see in the pictures that this kit completely encloses each blade with a baffle that extends down as for as the outside edge of the deck and is constructed of the same 7gauge steel. It does a FANTASTIC job mulching!!!

I apparently cannot remember user lawn mower fanatic's instructions on inserting pictures as it is a MESS and I can't even get the final pics of "After" to attach(and editing my post doesn't seem to help). Don't know how the "B4" pics also got attached as "Thumbnails". I guess me using Windows 7 as a virtual machine inside my iMac may contribute to my difficulties. Maybe since user lmf has administrative rights if he happens upon my post in this thread he can get my attached photos(B4=3597-3600) and (After=3601-3608) straightened out in this post(I'll keep trying but I really need to get outside and "mow my lawn:0)
I give up:0(
I ended up "losing" the first "B4" pic by trying to delete the attachment(#attachment#17409, photo#DSC03597). The "insert image" screen just seems to show the "top 8 pics" and has a "scroll up"....but no "scroll down" so I cannot get to pics DSC3606-3608(final Afters)...OR to the "re-inserted" pic#3597(first B4).........HELP admins!!!!!:0)
