If you can buy the plate, then you can make your own. Or have a welder do it.
I did it with my Kubota. What is great about making your own, is that you can make it be dual purpose. I use my plate for attachments and forks.
I have a FEL QA adapter for 3PT attachments. Not sure what the brand is but I got it from Rick Wallace Tractor in Lake Ariel PA. Rick is on TBN in the Kioti forum most of the time. The adapter works very well and includes a Class III and Class II receiver hitch as well as the 3PT.
