Sask | What you want is an anchor shackle.

A good shackle will have it's load rating in tons forged onto the hoop. Don't buy one without it. The listed size is the diameter of the hoop, not the pin which is larger. They come in carbon steel, stronger alloy steel and weaker stainless steel. The screw pin type is handy and safe for farm towing, and you can wire the pin if it's for long term use. Breaking strength is 6 times working load limit, and I've seen a 1" carbon steel shackle make a Steiger Panther spin on dry ground while it was pulling a 4" gas line under a road. | |

Be careful using a twist clevis.
