I don't have a DK4720se. I have a Kubota L5740 and a Kioti CK3520se.
I do not have a 3-point quick hitch on either of them.
I thought about going that route, but after fighting with getting the implement pto shaft connected to the tractor pto, I decided I didn't need one more thing to be in my way.
I put the Pat's Quick Connect couplers on the Kubota. They attach to the 3-point lower links so therefore do not get in the way of with the pto shaft connection.
I have not put anything on the Kioti, at least not yet. I don't have much for implements that I use with this tractor, so I don't think I need anything. But if I did, I would go again with the Pat's.
