Check your owners manual. On my TN 65 New Holland there is a screw on the side of the valve you turn in or out to switch between single and double acting cylinders. You might have something like that on your JD valve.

Thanks for all the suggestions. After reading them I went back and found that I had the linkage from the control adjusted wrong. After readjusting it, it now works correctly. John Deere provided a nice thick set of instructions with lots of drawings and pictures but the actual instructions were poor if not down right wrong. They said to do a lot of disassembly that was not necessary and the instructions for adjusting the linkage were wrong.
Spence, I bought my mixer from Tractor Supply. It is made in Italy. It too has a cheap single acting cylinder and I sometimes have to push on the mixer to make it dump but then the mixer barrel is not very heavy. I am sure that when it has any cement in it there will be no problem getting it to dump. There are five sets of holes on mine for the 3PT lift pins. I used the holes that are on the level of the drive shaft so that the change in length of the PTO shaft is minimized when the mixer rotates to dump. Otherwise there is too much change in length of the shaft. I set the lift arms to have the PTO shaft horizontal to thus the shortest to find the maximum lenght to cut it. I then raised and lowered the arms and raised and dumped the mixer to find the operating limits for the mixer. You will find that you have to limit the operating range of the lift arms. I found that I need to raise the lift arms for mixing and lower them to just below horizontal when dumping so that I do exceed the maximum angle of 35 degrees on the u-joints. If I lower the arms too much I will extend the PTO shaft too much. I think this is a very difficult application for a 3PT implement. A hydraulic drive motor on the mixer would be a much better solution but of course more expensive.
