My TC 29DA has the same ring.
I don't tie it such that the chain will be pulling straight down and jerking on that ring over bumps.
My first chain goes through that ring and through a D ring on the floor near the rear of the trailer then grab hooks onto itself with no binder. I then drive the tractor forward to tension it and set the brake. Then another chain goes around the drawbar and forward with a binder. Finally, a chain goes over the bucket arms, near the bucket, and across the trailer, with another binder.
The heaviest chain load would be in a panic stop or if I hit something. So, The forward load is shared by the ring an the bucket chain. The ring chain runs at a gradual angle to the rear to prevent jerking over bumps.
If you really want to get carried away, you can add another chain and binder across the box scraper or backhoe to keep the tractor from working it's way sideways over big bumps. Not needed unless something really extreme happens.
