This is a genuine OEM sourced replacement part used on Snapper and Murray lawn mowers. Mulching blades are designed to circulate the grass longer so it can be cut into smaller pieces. This makes your grass clippings better as mulch since the smaller clippings will decompose more quickly, releasing their nutrients into the soil. This part is made out of metal and it is sold individually.
