New rotary cutter blade sharpen or not?

[LoneCowboy]

No

rotary cutter blades wear out, they don't get dull.

don't touch it.

Thanks guys, didn't touch them, just replaced them. Wow what a difference with the new blades and bolts, the cutter runs as smooth as new again. It had been vibrating for a while now and I noticed the last couple of times it was getting worse. I placed the old blades back to back and found that one had about 3/8" less width about the last 8" of length no wonder it was shaking.

They will need to be "touched" over time as they wear, but not very often.
