Uneven MMM deck

[organ grinder]

Discovered a problem this afternoon while winterizing my pull-behind sprayer. The 62C MMM deck is not raising fully on the right side. It drops down just fine, but when I raise it, the left side raises to the full height but the right side droops. When I have the deck locked in place, the left side is fine, but the right side is lower if pressure is released to lower the drawbar. Can anyone with more mechanical skills than I have (which will probably include most people who read this thread!) give me some idea as to what is causing this and how to correct it? Many thanks.

Is the pin in the right rear deck lift arm? I had one pop out even though it is spring-loaded and the other arm will raise the deck - unevenly...

Well, the rain finally stopped so I could get the tractor out for a closer look in the bright sunshine. The problem was a broken hanger bracket that had separated where the threaded part enters the hanger. Turned out to be a simple fix and a relatively inexpensive part.

That hanger pin (cast aluminum) failed on my deck about 8 weeks ago. The fix started out to be a $37 part. Then I was notified that that part was no longer available in the cast version and I had to switch to a welded steel hanger pin. Problem was the treads were English, where as the cast pin was metric threads. Good news was the new pin was cheaper!

BTW, my hanger pin broke at the same section as your did.
