Vibration

[Steve11973]

I hit a brick the other day and now I have a vibration. I replaced the blades and now the vibration seem to stop when I engage the blade. But when it's just idling it vibrates. What did I do?
The mower is a Honda HRR2163VXA

Thanks Steve

Bent crankshaft. Either replace shaft, replace engine, or most likely replace mower. Sorry
