I have taken out that baffle on a couple of my mowers. Removing it does help a bit with clipping dispersal and clumping. Tradeoff is slightly less vacuum so not quite as crisp a cut. Very easy to remove and install. Also, enlarged the opening 2" on the discharge on a 60" ultra cut. Cuts much better in wet conditions, much less clumping - up to a point and less packing of grass under the deck. Again, the tradeoff is loss of vacuum. Does not cut nearly as well in thin, wispy grass. Am thinking of having a baffle fabricated to fit the larger deck opening.
