Pintle Coupling

John I've got one on my cruiser and can't find anything wrong with em'. They are a lot more heavily constructed than a normal towball setup. Also gives a good place to snatch from.

I bought an ex army trailer once with the ring and pintle. Very strong construction but I found the clunking noise it made when travelling quite annoying.
Cheers,

Never a dull moment

I've towed a Cub supamatic all over Oz using a pintle and ring coupling for over 20 years with absolutely no problems. Towed all sorts of stuff as well as snatching stuck vehicles off the back of the trailer.
You can get rid of the clunk by twisting a rubber plumbers ring (used to seal the joins on old earthenware pipes) into a figure 8 and placing it over the opening bit.
I have always had a swivelling ring on the trailer and a fixed pintle hook.
I have recently fitted the pintle with a ball built into it on the Humvee (needed a ball as well with no towbar) and it tends to wear the ring a bit due to the hardened ball I suspect but will probably stop when they match better.
I can send a pic of the ring if you want.
