Well, I dug out the tractor last night and checked the "bar hitch, sure enough, won't come off too easy. From under the tractor using imprecise measurement tool (tape measure in poor light) , I can offer: total length is 38", width is 2 1/4" and thick is 3/4". Hole for fwd anchor point is about 3/4" dia and is roughly centered at 4" from fwd end of bar. There is a hex head bolt and washer that partially covers the pin head (pin retaining, I am guessing). Rear hole is distorted on mine, probably was round, once but am guessing it is 1 1/4" dia, was probably centered about 1 1/2" from end of bar. best guess is about 16" from end of pto stub to rear hole though this is hard to establish with certainty. I have three other holes in my bar, 1/2' dia with centers from rear of bar at 5", 7 1/2" and 11". Hope this helps, if not, let me know if any more info required.
