I'm in the market for a 36 wb. At my local Scag dealer he told me that in his business he always removes them, the flap that is. He says it just gets in the way. I can see how it would when it comes to passing through gates and such. What do most of u guys do, leave the black plastic flap on or remove it permenently? And for that matter, do u replace it with a mulching plate or just leave the discharge side open? Is this dangerous?
