OK, so I hot one of my stepping stones with the right blade the other while mowing. Stupid I know, but it was a mistake. It immediately started making a very loud clanking noise. I disengaged the blades and noise went away. I got underneath and could tell the blade was bent and was rubbing and hitting the deck. I replaced the blades and the new blades spin freely without hitting the deck. Started it up and the clanking noise was still there when I engaged the blades. So I replaced the spindles, thinking maybe the shaft was bent or the bearing was blown. Started it up and the clanking noise is still there. any ideas? Could the belt be loose or some other bracket be broken I am not seeing? Both blades spin freely and without obstruction by hand, I appreciate any ideas.
