I have the Pats Quick couplers which are not as good but still a big improvement over the old push pull attachment process. I remember keeping a digging bar handy to move the attachments into position when needed. Although I gotta say the new extendable swayable links on the MX make the job way easier it is still the easiest with some type of quick attach and the Euro links look to be the best solution... maybe later, for now I'm happy with Pats. I like that I can drop the spreader bar in the connect to class 1 or 2 attachments without fiddling around - just set the spreader to the marks I made on it for this or that width.
The spreader bar is unique to the Pats set up but it would be real easy to make one for any set up.
Enjoy the new setup... what are you going to do with all your free time
