Looks strong enough to pull a trainI built this today for my tractor and skid steer. It has a ball for moving trailers and a chain hook and eye for carrying suspended loads or pulling out fence posts.

They don’t but I never latch the hitches anyway. I used a 2” ball so it will work on 2 & 2 5/16. It is flat as a pancake here and all I ever use the trailer mover for is moving them around my barns and stuff. I had a similar setup that just slipped over a pallet fork that I used for ten years and never latched the trailers or had any issues.Hope all your trailers use same size ball... Otherwise nice build...
