Ford swinging draw bar, uses, pic

I finally got all of the pieces together to mount my original Ford swinging draw bar. This is a picture of it. I dont know what I am going to do with it, but it is on! In the past I normally used my 'V' type solid mount braw bar for pulling things, but now I have this as a second option. What was some of the original uses for this set up? What do some people use it for now? Are there any advantages to using this type of draw bar? Someone once told me that it was used with a PTO driven corn picker, but I think that was incorrect. It appears the PTO shaft would hit the draw bar. Thank you for your input. Philip.

BTW, the swinging drawbar is also good for pulling something with an offset tongue, or where you want to offset the implement to one side (imaging both of the pins on the same side of the PTO shaft-keeps the drawbar to the right or left).
