I am using a Pat's on my Mahindra 1626. I like it okay. Much better than not having it, but I still have to wrestle with it a bit. Seems like that Harbor Freight one would be easier.
The quick hitches like the one HF sells work great as long as the implements you are using adhere to the Cat 1 Geometry. the problem most have is that the implement manufacturer didn't adhere to the geometry for the hitch. in the picture below they left out the height for cat 0 which is 12".
