Could it have been a defect maybe? Or are you certain that your reletivly new mower had a cracked deck because of something probably 1/2 the people that own one never do?

Crack a deck because of an unbalanced blade? I don't think so (unless you only sharpened one side of the blade and it was that far out of whack).

I don't believe for a minute that not balancing blades would cause a deck to crack. Do you really think that blades stay balanced while in use? Depending on the lawn they could be out of balance within minutes of use. Now if you ran the machine with it shaking violently, then maybe so but more than likely it was metal fatigue.

Over 15 yrs not a once have I balanced a blade, I have a toro 52" wb that was one of my original mowers, still use it here at the house. The spindles pulleys have a groove worn in them from the deck belt, but never replaced a spindle in all that time. Greasable spindles. Ran toro for 15 yrs. Switched to Exmark 60" mowers this year, so we will see how these ungreasable spindles hold up.

It should stand to reason that you need to clean the blades a little before you sharpen them in this case. However; the caked on stuff should also be somewhat evenly distributed on the blade since it is spinning at a very high speed.
I don't think I would want to trust the plastic cone balancers too much. They are made of pretty cheap plastic. They do make metal ones that seem to be a little smoother operating and likely more accurate.
Any time you spin that piece of metal the size of commercial mower blades, with that kind of weight, I can't see how anyone would think that it wouldn't hurt the bearings that support it. Maybe not over night, but they will wear out much sooner than they normally would. The vibration that they would cause would be somewhat isolated by the chains, or other linkage that support the deck. You wouldn't likely feel that much of it, even if was fairly bad. You may not notice it at all with all of the other vibrations that the machine is making.

I balance my blades before they go back on the mower. It only takes about 30 seconds of my time and it cant hurt. Walker 48" and 52"
"There's someone in my head, but its not me."
"Is there anybody out there?"
"Hey you, don't help them to bury the light!"
"The ones who really love you, walk up and down, outside the wall."
If quizzes are quizzical, what does that make tests?

I take a wire brush to my blades, then I sharpen them, then I balance them. My X father in law taught me that. Been doing it that way ever since.

Once again it has been proven that LCO's can run their businesses differently from one another and still find success. Balancing or not balancing...seems like something you'll never get everyone to agree on, just like Chevy vs. Ford. It's another question that finds an answer that's neither right nor wrong, just a personal preference.

IMO balancing a blade probably a good thing for a very short period of time, but I don't do it for various reasons. I used to balance each blade but quit doing last year because of the very reason someone else mentioned...have you ever taken off a dull blade and checked to see how out of balance it is?? Don't scrape it down, don't do anything to it, just throw it on whatever you use for a balancer and 99% of the time that blade will not be in balance. At what point did it become unbalanced? How long has that blade been used while being out of balance? You don't know for sure, it could have hit something right away and been out of whack the whole time.

But again, we all run our businesses differently and whatever you feel works best in your it. Now does anyone know how to manufacture rain???

balancig blades

One thing that putting a blade on a balancer will do is tell you if it's bent or not/ the blades you buy are seldom balanced perfectly. But it can't hurt to balance a blade, better safe than sorry
