Can anyone tell me if the pintle hitch on an M931A2 is the same as the one on an M915A1? I have a drawbar style hitch to fit in place of the pintle hook on the 915 and I would like to take it along so I can pick up an implement on the way home with a 931 I recently bought. I need to know if it will fit. Round shaft I would say 1 3/4 or 2" in diameter. The pictures look like it's the same thing but I am not positive. thx
