Hello all ! My father just passed and he was a Deere mechanic so I’m on my own now... I need to replace the pulley attached to the belt tensioner. The bolt on pulley spins, nothing to hold on bottom. And bolt holding bracket on is also spinning.. is there a way to hold the bracket bolt from bottom side of the deck? Didn’t have time to hoist mower up, baby ( 6 mo. old) needed dinner so I ran outta time... also not sure if that pulley is different than the other idlers, before I order one.
