I checked out the ULTRA BLADE sponsor and liked what I saw, the cut and discharge effect on what looked like dry turf. I'm thinking about using these for cool season turf w/ a leaf coating for the mulching side of it. Anyone have any experience with using these blades on damp turf and leaves? I would tend to believe that, being damp conditions, may lend itself to clumping and clogging a TRAC-VAC tube. ?
