When using a 21", does anyone have a preference? Plug or Side Discharge? When I plug, the grass seems to end up on the sidewalk when I turn the mower around for the next pass. On the other hand, if I side discharge the clippings, they can end up in mulch, beds, gardens, etc. (This is obviously for a non-bagging scenario.) Any preference? Is either way better than another? I'm using a Honda HRB215 with double blades and a Toro Commercial Recycler. Thanks!
