Well I finally found out why I have so much blow out from my Lazer Z. Its missing the front baffle under the deck. I bought it that way so I never knew it was suppose to be there. Now my question is this. Its the factory installed baffle at the front of the deck. Where can I get one. My local dealer says he can't. Its an LHP4818KC. looking at the specs diagram there is no number for it. No its not the mulching baffle. The diag says MK483 44"-48" side discharge deck assembly. Exmark man, can I get this from the factory. Its an old unit but still runs great, so I don't want to replace it, I don't have that much $$ to spend right now.
