What is a mulching plug on a lawn mower?

With the Mulching Plug in place, the freshly cut grass is held under the lawnmower deck rather than being collected in the grassbag. Here it is cut into very small pieces and blown back into the grass to help fertilise your lawn. The Mulching Plug is normally already installed in the lawnmower at the time of purchase.Click to see full answer. Similarly, it is asked, what does a mulching lawn mower do?Mulching mowers have special blades that cut the grass, then cut the clippings over and over again until they’re very small. Since grass clippings contain between 80 and 90 percent water and the clippings are cut so fine, they dry up very quickly. It’s almost as if the grass clippings disappear.Subsequently, question is, 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. Moreover, do mulching lawn mowers work? The blades of mulching mowers are designed so as to leave behind finely shredded grass clippings. By contrast, because lawn mowers without mulching capabilities produce clippings that are bulkier and readily mat together, their clippings need to be removed from the lawn, so that the grass does not suffocate under them.How do you mulch a lawn mower?First, insert the mulch plug in the mower and close the side-discharge port. Then mow as you would normally and make a second pass at a right angle to the first to thoroughly mulch the clippings back into the grass. Or bag your clippings. This works well when the grass is of normal height and the leaves are dry.
