Ok, I didn't realize you were at home. Dry leaves shatter really well! I personally prefer a dull blade on a mower when it's cleanup season and I'm mulching them in. I don't want to cut them into nice clean strips, I want to obliterate them into tiny fragments! I've jumped in the dump bed with a trimmer for a few properties where we loaded a lot of leaves that weren't processed. Not as efficient as a loader .. but when all you have is a trimmer, everything starts to look like grass?
