Thanks for the reply, I want to report back so that it may help someone else.  I forgot that I had changed the belts a coupla weeks ago.  In doing so, I must have re-positioned the blades OR maybe they were too close all along.  I unbolted nearly all the bolts on the deck underside and was able to reposition it far away from the other one at any point during the spin,,.  The fix held.

They are keyed as to not interfere with each other.  The broken key is the only explanation that makes sense.  I’ve gone through this before with my 502 deck... not a terrible job.  That deck sure did cut good!
