Please help me understand why you consider the drawbar length to be important as the only important specification for a tractor drawbar is that it should be mounted substantially below ( ideally at lowest possible point ) the center line of the rear axle to prevent the tractor from rotating around the rear axle and crushing the operator. The drawbar must be prevented from jackknifing upward and thereby effectively changing the relative point of attachment.
These attached pictures and dimensions are of a JD 4320 compact tractor. I think this 4320 tractor is a cousin to the 110 loader backhoe. The draw bar is 1.25" X 2.50" X 20.50".
The pin connection to the tractor is at the 2.25" dim. The 8.62" dimension is the end of the support shelf on the tractor adapter. The draw bar over hangs/ is not supported/ from the 8.62" dim to the 19.31"/ connection point. Because of the tractor c plate interference, the draw bar cannot shortened and pinned 6.38" dim. It only pins at the 2.25" dim. The 15.25" dim should be for a safety chain connection. Hope this helps. Later.
Thank you much, Oldtimer. That's a short little fellar, LOL, compared to my Case 5250. I do have the welded drawbar hitch bracket but believe the dimensions to be the same. You are a life saver.
