What you need is the quick tach for your loader. According to my wholegoods price book there isn't a specific quicktach from Kubota for your loader. However, I have run into this before and I have taken measurements and used a Kubota QT from a different model ex QT for LA504 will work on the LA364 loader.
If you get along well with your local Kubota dealer, maybe he can do a little research for you and cross fit something that will work. A word of advise, make sure it is a "Skid Steer Style" QT you purchase. That way you wont limit your options for attachments.
If you have no luck with your Dealer, let me know. I will research it for you.
