This Euro style hitch has been available for a looong time.
And yes, it does exist in the USA. Brian at Fit Rite sells them,
Not need to lift the arms by hand to align and slide on the pins, or to keep kicking the arms till slides on the pin like the fixed ends or to move the implement around by hand to get it square to the tractor.
I basically have a similar hitch on my 4105 JD,, Pat's Quick Hitch.
yes, it is nice.
You still have the multi step need of adjusting the width somehow,,
as well as the time of correctly positioning the tractor,,
I like my extendable arms better than the Pats.
but,, wear,, Hmmmmmmm,, a couple thousand hours pulling a dusty plow will destroy any end.
That type duty will even destroy the top link.
Search for a JD CAT2 top link on eBay,, most of the used ones available need the ball end near the attachment replaced.
The ball is falling out due to wear of dust in the top link end.
But, I agree, 10,000 hours of "Gentleman Operation" of a tractor (mowing, moving hay) will show zero wear on any three point hitch end.
