This one came in while I was writing my previous reply.
My manual showes the same 14" requirement. I believe that is the ASAE 540
PTO standard. It doesn't need to be all that exact. At least, mine are
not. A little longer is better than a little shorter to keep the u-joint
angles down. On the old Farmalls with Fast-Hitch you needed an extension
plate that bolted to the drawbar to get to that standardized length.

I just found the problem a few hours ago. It is the height of the hitch. The
clue was the owners manual that I was reading for the fourth time, and it
warned that you should adjust the flotation springs after you switch
tractors since hitches will be different. That set a lightbulb off in my
head. So I flipped the hitch bar so that the tongue of the mower was 4
inches higher. Voilà I now have a floatation weight that approximates
specifications.
The manual says that the hitch should be 13 to 17 inches above the ground,
but I thought the PTO shaft was at too sharp of an angle. So I had set the
hitch for the lowest position which was about 12 1/2 inches. Close enough I
thought.
I thought wrong.
I did not need to tension the springs any more after that.
Problem solved I think! Now all I need is a spring scale that will measure
past 50lbs so I can assuage my curiosity. I think it's 85lbs
Now I wondering about something else. The manual says the end of the pto
shaft to the hitch pin hole should be 14" exactly. I can get 13 or 15.
Seeing as how finicky hitch height was, should I try another bar and get
that 14" exactly? Or is there some wiggle room in that measurement?
