Hitch question, trailer tongue.

[QRTRHRS]

Anyone have any experiance with this type of hitch? I have a Swisher pull behind mower with a tongue that pins to the hole on my hitch. I have to manhandle the mower to get the alignment just right. I was thinking of some kind of pintal or maybe just a standard ball hitch.

This looks like it might be pretty easy to "land" on a ball and give me the flex I need.
