going after my new-to-me  disk this week.  No harrow, so  should be  pretty decent tongue weight.     Decided to just  pull it home behind the  dually.     I got the  receiver hitch  reinforced pretty good  on the  flatbed,  with  bracing back up to the frame.  It's  definitely  triangulated in. 

So,    with these 'lunette ring' style  hitch on the disk,      would  any  pintle hook work,  or   do I need   the  ball style pintle   hitch  for the  truck?     Local  guys sell  the Curt brand  hitches, and have both styles..   But they have no idea  what works on what.  They are just  box store resellers.

This is  probably a one-time  deal,    for  about  75 miles.
