I just bought a new set of Gator Mulching Blades for my John Deere 42" deck and when I took them out of the box to install, the cutting edges appeared to be dull. They looked like they were coated and the edge was very smooth. From my experience with lawn mower blades, I have always kept a fairly sharp edge on them. I suppose if I tried, I could probably cut my finger handling the blades if I wasn't careful. These brand new Gator Blades wouldn't cut a good F**T. Any thoughts??????????? After using them, they did a fairly decent job mowing....but nothing to write home about. As for mulching the leaves....not too terribly impressive.
