Yes. Cat
Yes. Cat 1 pins are 3/4ā and cat 2 pins are 1ā. Cat 1/2 hitches require the 1ā pins, but will adjust the arms narrow enough to accommodate cat 1 implements with a cat 2 conversion bushing.Cat 1 is a smaller pin and is definitely what your tractor has. As you get at 50+ HP (or so) many brands start offering Cat 1/2 that can handle the thicker pin for heavier duty work. The really big ones will go Cat 3.
My internet cables are Cat-6, but that's another topic.
