Then somebody's got something wrong. Full Cat 2 pin spacing is 32". What I think you're lookin' at is a Cat 1/2. Previous advice is germane, measure the distance between your implement lift pins. Otherwise the Cat 1/2 connects to Cat 1 lower lift arms, but has hooks big enough to pick up 2 lift pins.
I personally got so frustrated with my HF QH, that I replaced it with Pat's Easy Change hitch system. Never looked back.
