When to replace mower blade

Never understood people who took a chunk out of the wing for balance. If my blade is off balance I take a couple more passes on the heavy side with the sharpener. The wing is the part of the blade that creates lift and circulation and you shouldn't mess with that
 
You know I have the advantage of only mowing my yard which has no surprises. The picture looks like the blade hit a thousand mole hills to be ground down on the end!! The little imbalance I see when sharpening is fixed by grinding off the end of the offending side of the blade-usually no more than .020"-.060."

I don't think he took a chunk out of the wing.

I run my blades till the wings wear like that.

Now the curve. Never mind I will be nice.
 
Ouch, as I can see sharpening is not my skill.

I did nothing to the blade. The cruve is just because I sharpened it so much (for a while I was sharpening every day). Is there a better way to sharpen without having that curve?

Now about the wings. Each wing has a hole in it for a certain reason. When the wings started to wear off, the hole was dissapearing, so I just grinded the hole slightly to not have an extremely sharp edge on the wings.

I do go over a few ant hills and such. I guess that doesnt help.

I still am not sure how you got the curve.
How do you sharping blades? What do you use?
 
I just use a normal grinder with the wheel it came with. I just do many passes until the blade is sharp and I make sure that I have the right pitch (45).

LB18 first off ignore this user, he does not have a clue what he says and only follows around a mod kissing his butt.

Okay wow you like to sharpen which is good, however I think you went a little hog wild there with the grinder. LOL
Now you are using the wrong type of wheel to sharpen your blade you need a flapper type wheel with 40 or 60 grit, then be careful to try and maintain your pitch on your blade while sharpening of 30 degrees.
Grass, dirt, sand, leaves, sticks, it is all hard on blades and metal is just metal so don't feel too bad or worry about how it is wearing or deteriorating, it would take 2.5 or 3 of your blades to make one of mine and my blades are not as wide as they were when I started mowing this season because I constantly check them and hit them with the flapper wheel every week maintaining their edge, but when you mow 12 plus acres per week your are into a some grass.
But to answer the main question; I personally would not have allowed my blades to wear that much before replacement, but each is their own.
