Ours sure as hell did.  The couplers were completely crap as far as I am concerned.  Usually took about ten tries before you could get all the hoses to stay in when you hooked up, then periodically throughout the day whenever you were nice and comfortable in the cab one would pop again just for spite.  That magnum was the worst I have seen, but the Challengers aren't a terrible lot better and current Deeres aren't perfect either.  The ISO converted Deere's work fine but they leak all the time.  50 series Deere's actually pretty well worked like they should. 

Funny thing about it......the cone type couplers on our 42 year old 4010 work just fine, and for the most part the cone style always did work.  They would couple under pressure just fine as long as you had something to give you enough leverage to pop the flipper lever back to on after you got it in. 

There is no excuse for having to go through all this "make sure the hoses are completely depressurized" crap to hook up a modern tractor but it seems to be a universal feature.
