This replacement 20 inch blade is a high quality item that is supplied from original equipment manufacturer for use with Lawn Boy and Toro lawn mowers. Mulching blades are designed to circulate the grass longer so it can be cut into smaller pieces. This makes the grass clippings better as mulch since the smaller clippings will decompose quicker, releasing their nutrients into the soil. This part is made from strong durable metal and it is sold individually.
