hi Gary
The Imatch also requires a bushing, I paid 10 bucks a pair for the Speedco bushings which work with the Imatch too.
All my attactments are Imatch compatible at this point. My dealer was unable to get me the Imatch for the weekend so loaned me a Speedco hitch, so I've had a chance to try both.
I have a JD lx 4 rotery cutter, frontier BB and frontier land scape rake, the Speedco did not work well with any of em, one attacthment worked with the upper hook, the rest did not, so I was constantly removing the hook and installing the adjustable upper link, it seemed to me the hook did not stick out far enough, the bolts that hold the hook on would hit before the hook would engage. It was not a quick hitch, I spent more time working on attaching implements then using them. The Imatch works as advertised as long as your implements are imatch compatable. In my opinion the time required to remove the hook and install the adjustable link defeats the purpose of a quick hitch, it would be better to modify you implements to fit the the solid hook on the hitch.
