Vibration causing gas tanks to break?

If the blade has touched the deck, it is time to take it in and have a professional take a look at. Your blade probably needs to be replaced, at the leasted sharpened and balanced. By the way your posts read, I advise you not try to repair. In my opinion, you may cause more damage and injure yourself or someone else. Even straightening a crankshaft (which I would never attempt) should only be done by someone who has years of experience. My last post on this thread.
 
The rubber under the tank straps are just a cheap try fix. If it has a bent crankshaft which would be a major repair what I would try frist is a big hammer and see if you could bend it back. As far as a mower blade why not a new one, less then 20 dollars a cheap fix.


Good suggestion, Reynolds. Might do just that.

Rivets...

To close the thread...

This spring, I turned my mower over to inspect the crankshaft and discovered my "universal" blade was perpendicular to the angle it was supposed to be -- hence the excessive vibration. I replaced it with an OEM model and so far so good. Thanks for pointing me in the right direction.
