I have to use an open end crow foot wrench on one of my New-Holland 781 lines under the body of the loader ---nuttin else would go in there. Crow foots are nice when you have little space to work in.
I had heard that some of the machines from Japan and other countries over there have some tight bolts in them -----good thing in one way but a pita for us guys when repairs are needed.
