|This authentic replacement part is sourced directly from original equipment manufacturer. This blade is designed for use with riding lawn mowers/tractors. 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. To replace it you would need a wrench to remove the nut that secure the blade.|
