Kraig -
A small tidbit I found is that the Pto lever end where the fiber button goes is forked. I looked in the first TC-103 and the drawing indeed shows that the end of the lever has a slot, and not just the hole for the button. I don't have a pic of the tractor right now, but if you've a TC-103 it would probably show the lever that way. I've never seen any other lever like this. I don't think many levers got out with the slot as opposed to a hole.
