Product Description

This is a Genuine OEM sourced replacement part used on Black and Decker Lawn Mowers. This part is made out of Metal and it is Sold Individually. Mulching lawn mower 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.

I'm trying to find a replacement blade for my B&D mulcher, model #MM575. B&D part number is 243550-00. It is discontinued so I'm looking for an off brand blade. The center hole diameter is 7/8.
For model number MM575 logo
Hello Mason, thank you for your question. Unfortunately, we do not have this information listed. This would certainly be an issue for the manufacturer to address. For more specialized assistance or to speak with someone about this, we would suggest calling the manufacturer. We hope this helps!

Does this blade need to be sharpened before use?
For model number FIX12004284 logo
Hello Jennifer, thank you for contacting us. The new blade from the factory is already sharpened; you do not need to sharpen the blade. When its cutting edge gets dull or gives ragged (uneven) cuts, then you will need to sharpen it. We hope this helps.
