I also have a 100 with the 42" 3-spindle deck and have the same issue. Haven't been able to find out if the deck was supposed to have baffles in the first place, and if it did, what they would look like & how they'd mount to the deck. Curious what others have to say about it.

So far I've waited until the grass gets a little long, 6" probably, kept the standard issue (not Gator blades) Cub Cadet/MTD blades sharp, overlapped by roughly a 1/3 of the cutting width to recut the clippings and have had good luck with getting the clippings down to a reasonable size. I usually cut the grass to 3.5" in length. The lawn looks better after I run over it with the tractor alone than when I use my walk behind Toro mulching the grass alone. I'm happy with the results so far so I haven't gotten too bent out of shape about the deck missing the baffles.
