My Grand L has CAT 1 upper, and CAT 2 lowers ... I purposely Bought a CAT 1QH as have lots of CAT 1 attachments ... I wanted an adjustable hydraulic top link, in order to get the length I needed, I had to order a CAT 2 on both ends, so I used bushings to size it down ... Since the lower part of the QH needed CAT 1 pins to hook it to the tractor, I just used bushings to fit ...
Why in the world somebody decided to make the hooks on the CAT 1 QH CAT 3 size is beyond me! But use the "mushroom " style adapter bushings on all my attachments on the bottom , and a couple of sleeve style bushings up top ...
