Sorta embarrassed to ask ... I should really know.

Easiest way. Forget the rope. Run a light chain from drawbar to pin in top link connector on tractor. Drive a round punch into the last link of chain to expand it to be more circular to fit the pin in the top link. Attach chain to middle of drawbar with a shackle or a quick link.
