Previous Qhitch discussions have mentioned its easy to widen one using a Hi-Lift jack.
I just looked and HF no longer shows their clone that they called 'Farm Jack'. Maybe too many injuries.
...
Added - I wonder if the hydraulic cylinder from my HF 'Shop Crane' could be removed, special brackets made, and then used to widen a Qhitch.
Or possibly the Shop Crane would have enough force to do the job unmodified. It has a ton lift out at the end of the arm so the force close in next to the cylinder would be a lot more.
