Newer owner of a L35 TLB with 1350 hours. The forum helped me repair one of my stabilizers now I have another issue. Part # 75595-2151-0 boom pin on the swing frame (1.50X10.20) seems to be broken in 1/2. The opposite end that does not have the hex bolt is working it's way out. I tried to get a picture to download but can't get it. Anyone else ever have this problem? What would cause this? I purchased the unit from an estate so I do not know the history of the tractor. Thanks
