I notice that the main difference with push mowers (mulching vs regular) is that the mulching mowers lack an exit chute for the clippings, thus confining them for further slicing and mauling. My riding mower has a chute out the back, which leaves big clumps of clippings all over the lawn. I don't want to use a bag or sweeper, not only since there's no means to attach one, but also because the lawn then would lose the nutrients from the decaying clippings, and require fertilizer. So I'm pondering converting the mower. What I envision: Welding a sheet of metal to the gap in the mowing deck, where the clippings would normally exit. This should contain the clippings and allow them to be more finely chopped. Is this a horribly bad idea that will surely result in the destruction of the neighborhood? Or might it actually work?
