My HF quick-hitch is cat 1 type for (7/8" dia. pins) but the lower slots accept cat 2 pins(1-1/8" dia pins). So to remove slack I changed my impl.'s from 7/8 to 1-1/8 pins.
All Cat I quick hitches are sized to accept larger implement pins. That is how the standard is set up. It's actually sized to accept Cat 3 pins (1-7/16") which is how the quick hitch adapter bushings are made (Cat 1 to Cat 3). That said, a lot of people do just use the Cat 1 to Cat 2 bushings and say it's close enough.
