I'd like to thank all the folks who responded to my request for info regarding male couplers for the NH TD95D.
Here's what I found. Our local repair shop told me their parker/Pioneer manual specified poppet type tips for the TD95D and I ordered them ($8.30 each). The thumbnail below shows a comparison between the ball fitting and the poppet tip fitting. Besides be slightly shorter, the poppet fitting has a slightly larger groove nearest the threaded end of the fitting.(This goes along with what Jbrink64 indicated in his response). The retention ring appears to located at the same distance from the tip in both cases and the poppet tip sticks out a little further (0.02" per the spec dwg). Notice that the net shape of the poppet tip coupler is different from the ball tip.
I installed them on the bale spinner and it works.
So my conclusion is that the poppet tips are required on the TD95D with the factory couplers.
This closes out this issue as far as I am concerned. i will inform my local NH dealer.
