A mulch plug is used to block the chute to the grass bag on a lawnmower, converting it into a mulching mower. Please note, not all mowers can be converted to mulching.

A mulching lawnmower doesn't collect or discharge the grass clippings, but instead repeatedly cuts the clippings so small into what's called mulch. The tiny clippings are then deposited back into the lawn, leaving a finished appearance as if the clippings had been collected. The mulched clippings decompose and act as fertiliser for the lawn.
