I've got a little down time today and decided to take advantage of it by sharpening the blades on my new Simplicity ZTR. They've got half a season on them and I figured it was worth a look.
The blades didn't have any nicks in them but the edges weren't what I'd consider sharp. The cutting edges seemed rounded and not as sharp as your typical butter knife.
I ground the blades so the angle goes all the way to the cutting edge.
I started looking on line for blades because I'd like to go ahead and have another set on hand. I noticed in one of the pictures the new blade seemed to be no sharper than mine were when I removed them.
My previous mower had a mulching deck and the curvature of the blades made them difficult to sharpen. Since I had access to aftermarket replacements at wholesale cost (under $6 each) I always just replaced rather than sharpening. Those blades were always as sharp as I just made my Simplicity blades.
So I searched the internet for articles on lawnmower blade sharpening. Most of the articles say the blade should only be butter knife sharp. I understand why they shouldn't be ground to have a razor edge, but "butter knife" sure seems too dull to me.
Did I over-sharpen my blades?
What do you folks do?
