End of problem!!! /forums/images/graemlins/laugh.gif
I visited my JD dealer and talked to one of the tech guys and explained my problem. Remember that I mentioned a malfunctioning quick disconnect. He said that the malfuntioning quick connect was probably the root of the problem. So, I picked up two of them (always like to have a spare) and replaced the bad one a short time ago.
Fired up the tractor and voila!!! The blade goes up and down and back and forth just like it's supposed to. And, since the bad quick disconnect is brandy-new, it is under warrenty and I get a credit for it. Bonus /forums/images/graemlins/cool.gif
Thank you's to everyone that provided a suggestion.
