I have a set of Gator mulching blades on my 48" deck (LX188). While they could stand to be sharpened, since new they've blasted debris out the front of and under the mower deck. Most of the debris goes out the side as it should, but still there's a fair amount that goes out from under it - particularly leaves - and onto the muffler and atop the deck. I just got an Agri-Fab Mow-n-Vac and it works great, but there is still a lot of debris that shoots out the right, front of the deck. Do I need "regular" blades to work in conjunction with the vac? The Gator blades never really seemed to do much mulching - they left piles of grass along the way. I did not plug the outlet on the deck per the Gator blade instructions.
