How does a mulching blade differ from a regular mower blade on a lawn mower?
I use a Craftsman 17HP 42″ blade and I recently bought mulching blades for it. My lawn cuts unevenly now.Mulch blades may cut differently as they are designed to shred the grass repeatedly into small pieces as opposed to cutting it cleanly. Depending on what type of grass you have or how long it is kept, the lawn may need to be cut at a different speed. And you may need to cut more frequently and when you are certain the grass is dry. Otherwise you may get clumping of the cut grass which could cover and pack down your lawn is spots and lead to an uneven cut. Some models are not designed to work with mulching blades at all and others may require additions along with the mulch blades such as a mulch plate or block or baffle or skirt. Decks not designed for mulching or without the recommended additions might not be creating the correct lift and flow of air to properly shred and disperse the cut grass. Again, that can lead to clumping and pack down your lawn. Your Owner’s Manual or the Sea
