I have a Toro recycler 22" w/ personal pace & blade brake model# 20333 I hit a bigger rock and started a pretty strong vibration when you release the blade. When the blade is going it is mostly smooth. I bought a new Toro blade for it figuring it was bent and hadn't been replaced previous to this incident. Installed new blade and no difference in vibration when blade is released. Engage blade and it is again mostly smooth. Smooth enough it seems ok.

Have I most likely doomed this engines crankshaft or is there something else that is I am unaware of? When I slowly rotate the blade(engine off and plug wire off)visually it does not seem like an issue. I do not see any variation in the blade, but I can only spin it so fast. Again the vibration happens at idle

Any ideas? Thanks in advance.

Could you of bent the crankshaft. Check it with a dial indicator and see how much run out you have.

Disconnect spark plug

Watch blade it should not wobble in the center just spin if it wobbles the crank is bent
