Mowing Brushhog blade change??

[RxRatedZ71]

So I was brushhogging this AM and found my way onto a near flush-cut eastern red cedar stump (hard as he$#) and then my BH started making an odd noise. Looked underneath only to see one blade hung up on the pan. Couldnt free it in the field so had to flip it over and remove the pan. Turns out that the dealer/factory put a blade on upside down. Its been cutting with the backside of that blade all the time.Probably explains why the clippings arent cut up that well. Got it righted and back up and running and it cuts alot better. However but it seems to want to wobble. Should I be concerned? Should I try to sharpen the other dulled blade or buy a new set and keep these for spares?

I think I would buy a new set of blades and install them, just to see if there is still some "wobble" going on. That could possibly be a bent pan, or worse, a bent output shaft on the gearbox. I think you need to try and narrow it down and blades would be the easiest starting point. Hopefully that will solve the vibration problem.

If one blade was taking all the abuse on the sharpened side could cause a wobble. My dad and his mechanic experimented one time with a push mower. They taped a quarter on one side of the blade to see what would happen. It took out the engine!

Wow, talk about getting their moneys worth.

I thought about sharpening the dull one but thought might really exagerate the difference and compound the effects.

I'd try a new set of blades, and take the old ones somewhere to get sharpened. I'd ask them to trying making them similar to one another...even if that means taking a little extra off the better blade.
