Hi guys. I'm trying to help my neighbor out by locating a part for him. He has an early 90s Ingersoll 4016 tractor with the Onan engine. It has the hydra bagger with the triple bags. He has been told that he needs a new hydraulic motor for the system. However, he has also been told that this part is obsolete and can no longer be found anywhere. Does anybody know more about this issue? Chris
