Does anybody make an OCDC for Gravely 48" walk behind? I have searched high and low for an OCDC (chute blocker) for my Gravely 1548 48" walk behind. I've searched dozens of threads, hundreds of posts, googled like crazy, called Powerchute, Advanced Chute, EZChute etc. and there simply doesn't seem to be an available OCDC for my mower. I would think a Gravely 48" WB would be a fairly common machine and thus there would be a OCDC to fit it? Any suggestions? Thanks in advance.
