This is a genuine OEM sourced replacement part which is specially designed for use with MTD and Troy-Bilt walk-behind 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 of high-quality metal and is sold individually. Please make sure to refer to the owners manual for the correct installation of this mulcher blade.

Very easy repair. Remove cog belt from pulley, remove nut from top of shaft and using a hammer tap shaft thru spindle housing. I left the blade on the shaft during removal. I installed the new grass blade on the new shaft prior to installing the shaft. I needed to be sure that the grass blade fit perfectly on the new shaft. Only other new part was the clogged belt pulley which fits over the spindle shaft and is held in place with the nut and washer. Be sure to have cogged pulley marks 90 degrees opposite from each other or blades will hit each other.
