A "mulch plug" is necessary to mulch the grass clippings during mowing. The plug is used to close the discharge opening in the mowing deck and recycle the lawn clippings back into the blade area for repeated cutting and eventually deposited into the lawn as fine mulch.
The mulching function on a lawn mower is activated by simply inserting a mulch plug into the discharge chute which prevents the cut grass from leaving the mower deck and entering the grass collector. This results in the cuttings being circulated within the deck and cut up into very fine pieces.
Similarly one may ask, how do you install a mulch plug? To install the mulch plug, lift the discharge chute up. Insert the mulch plug into the deck discharge chute opening by fitting the bolt on the rear side of the mulch plug into the hole in the deck. Pivot the mulch plug into place.
Note: Grass clippings are good for your lawn as they will offer healthy nutrients to your lawn's soil, and it is still fine to leave them behind after mowing. Longer grass can invite lawn pests, which often hide in shady areas of your yard.
While mulching mowers worked fine for contractors in dry, slow-growing grass conditions, others complained of clumping grass and an unattractive appearance, wasted time spent cleaning out sticky grass from mulching mower decks and how using a mulching mower once each week couldn't keep up with spring's rapidly growing ...
Can you install mulching blades on any lawn mower? There are mulching blades available for most mowers, but not all mowers should have mulching blades installed. Underpowered models may not have the horsepower to spin a heavy mulching blade at an effective speed, providing mixed results when cutting and mulching.
Any blades should work when bagging, but if you want finer pieces, you should use a mulching blade. Most of the time, mulching your clippings is the best option. You should bag your clippings if the grass is tall, leaves are covering the lawn, or you need to prevent disease and weeds from spreading.
No. Both side-discharge and mulching mowers leave grass blades behind. However, a mulching blade chops up clippings into finer pieces so they decompose faster and don't clump as quickly. Using a side-discharge mower you may need to do your own mulching by running over your grass piles multiple times.
