The King Kutter XB Tiller is not compatible with my Harbor Freight Quick Hitch (nor an I-Match or any other quick hitch).
This video shows the necessary modifications to the tiller to make it fit.

My John Deere 1025R handles the tiller very well. It is now much easier to hook and unhook from the tractor.
