It looked factory enough to me that I just assumed... Hopefully, Brian Gonyea or LW or Schrocky or someone more knowledgeable than I can give more info.
Brian K, I'll probably hang onto this for a while, but keep looking - they are out there. I'm kicking myself for not seeing one laying on a pallet at an auction a few months ago until after the sale was over.
I was looking at the specs on John Deere's big 4 wheel drive the other day and saw that its 3 pt capacity is 20,000 pounds now!!
That makes this early attempt at a 3 pt seem pretty primitive. Pretty amazing how far things have come.
