It is to the point  with arthritis in my hands that I can't put the 10 inch swing away  on the tractor's PTO.   If I'm hauling in corn and they forgot to connect it he has to get off the combine and come do it for me.   Pushing in while pulling back is like rubbing your tummy while patting your head.    And don't get mad and  raise your head too fast.  You'll hit your head on something still on the tractor.
