This is a genuine replacement part that is OEM sourced to be used with riding lawnmowers from Yard Man, Ryobi, Yard Machines, MTD, and Bolens. The plastic wing nut is commonly used to fasten the bolt that secures the mulching plug to the mowers deck assembly. This item is available as an individual replacement part.
This is an authentic OEM supplied replacement item that is specially produced for use on lawn mowers. Mulch plug is secured to the side of the mower deck to keep the grass under the deck for mulching. This makes the grass clippings smaller to be better as mulch since the smaller clippings will decompose quicker releasing their nutrients into the soil. Please note this durable plastic much plug is sold individually.
