Bx22D rear port lines for back hoe

[Lumberjack1012]

On my bx22d the rear lines that go to the backhoe there two ports but the bt601 attchment Im putting has three lines what I am getting at is I guess I have to install a return to tank/trans. line on the tractor valve body but not sure if there is a port plug or something available so i may have to tee into already dedicated return to tank line not sure what port/line/plug to use to acomplish this anyone done this I guess the bt600 that is supposed to be used only uses 2 lines no tank drain line I wonder why they went from 2 to 3

The two backhoe ports on the tractor are pressure out (P) and pressure return (PB) .

The third tank return on the BT601 backhoe can go to any tank access point. The oil filler jumps to mind but there may be other more convenient places.

Kubota has always cheated by using a cheaper two port BH valve with pressure IN and tank return (OUT) ports. That works as long as you never back pressure the tank port but its been a frequent cause of problems. They decided to do it "by the book" with the BT601 which has a 3 port valve with pressure IN (P), pressure OUT (PB), and tank return (T) ports.

Just for reference, my BH77 only has 2 hyd. connections.

Is this a “new to you” BH that you are installing?

If so, I think you would benefit greatly from a manual, or some sort of installation guide.

A tee in the loader tank return would be my preference.
