Yes, they think it is a shim problem, I will measure blade deflection when I get home today. See previous post from a form member's manual on this thread.Have you discussed this with your dealer? I expect some shuttering and a little noise on all our tractors, but I never get the big bang you are describing and would be concerned. Is there anyway you can upload a video of this, some TBN members have done so which gives us all a better understanding of he issue.
TripleR Post: This information is not in my manual.
In the section on assembly: Start by assembling blades without shim (#2). Insert blade bolt (#1) through blade (#3), dish pan (#4) and
flat washer (#5). Temporary secure blade with a used 1 1/8"-12 nut. Draw nut up snug. Do not tighten.
Check blade deflection. If deflection is greater than3/4", remove blade bolt and reassemble as before except include shim (#2) in the assembly. Select shim thickness based on deflection. The greater the deflection, the thicker the shim.
Once blade deflection is correct, replace used nut with new locknut (#6) and torque to 450 ft-lbs.
I cant post pictures,but it seems "possible" this was not assembled djusted properly, just a thought.
