Yoder, that looks like a very well-designed system. And I do like the weight it adds to the rear end. But unless I'm missing something, it would mean spending $362 (Cat 1) and $562 (Cat 2) plus shipping per implement just for the adapter plates. Probably why it hasn't caught on more than it has. Do you use it for all six of the implements you've listed?
Also, is it really as easy to align each time as the video shows? I know with my HF "Speedco style" quick hitches, the implements need to be set down fairly level and angled correctly (forward/backward) in order to back right up, hook up and go. Now that I have hydraulic top 'n tilt, that's less of an issue. But still, the marketing videos usually show things in the rosiest light.
