Leaf/debris Blowby W/uvac

[Strawbridge Lawn]

Recently got the Ultravac for my ZHP-52 and in using regular lift blades I note that there is still allot of leaf/debris blowout in front of the deck especially in thin grass areas. The only thing I can do to prevent this is lower the deck and take off more grass or at least let the grass be slightly above the deck height to keep it from blowing out the front. Can't do this everywhere though..
Did not expect this with the UVAC.. Anyone have remedies?
Thank You in advance

Many people have said that if you go to a blade that has less lift - perhaps a lowlift mulching blade or Gator, it helps signicantly. Also, the anti-blowout baffle that is available for the Lazers is somewhat helpful, but so is mounting your own flap on the front of the deck.
