I set up the funeral tent for funerals at the cemetery's. The guy that digs a lot of the holes for us has a loader tractor backhoe. When ever he dumps a load of dirt to fill the grave up, as he is tipping the bucket, it squeals like crazy. His helper was along one day and I commented about that that it needs greasing, probably need to pull the pins out and drill the dirt out of the holes so the grease can get thru, his helper commented " to much grease, in the tube. I had never heard it explained that way before, but he was right. catskinner
