I may be wrong, but I didn't think there is an industry standard or spec for quick hitch dimensions but more of an acceptable range...I am using Cat 2 top link (1") pins on implements and the HF quick hitch won't work with our JD Cat. 2 implements and the JD quick hitch works fine with these implements.
The standard specification is an ASAE (American Society of Agricultural Engineers) standard. It's not an exact number, it is minimums and maximums. We're talking about farm implements here, not machine tools. If an implement is not quite built to the quick hitch standard, it still may work with one quick hitch and not another because of the tolerances built into the quick hitch. I wouldn't put it past JD to build their implements slightly off the standard to conform better to the iMatch and not so well to other quick hitches. I know my Frontier box blade is almost but not quite built to ASAE standards and I had to make a slight modification to make it work with my HF quick hitch.
