I have included a pic from the Operators Manual. I hope this will clear up my question. I am missing everything between the yoke and plunger. There is no spring, no spacer, nothing there. Just a few remnants of what used to be. As a result the Ferguson System is not functional. Is it safe to use our recently purchased single bottom plow and a disc. Not at the same time, I know that much, J/K. Thoughts?
