Recently I developed a phenomenon with one of my Toro 44" sfs decks. The grass gets lifted and cut fine with no straglers, but I am getting a strip of clippings dropping out on the lawn between the 2nd and 3rd chambers. The deck is clean underneath, and I tried changing blades but it still does it. There is nothing apparently bent or warped that I can tell. I have 2 other decks set up identical and no problems. Anybody else ever get this, and figured out what caused it or how to fix it?
