Anybody ever made a device up on a tractor 3 point for moving a semi trailer around with ? I think it would need to have some flex or pivot in it for slightly uneven terrain and also I would also like to see it lockable onto the  trailer kingpin. Would only be for moving a short empty trailer around off road only instead of needing a truck to move.

Something similar in type to moving gooseneck hay trailers with a 3 point on a tractor.

Short piece of pipe would work but would like to see the load evenly distributed around the kingpin on the trailer too.

Any thoughts or pictures would be appreciated.
