Why no "Power Beyond" for Kubota tractor?

I know you went with the pto pump, but this is how the lxx01 series hooks the lines in for the backhoe. If you hydraulics block is similar all you would need is the line to put it in a loop.

And something like this for the hydraulics.

Ah, sorry to hear that you have had such bad luck. Putting a tee in won't work as it's an open center hydraulic system, fluid can flow in a loop from one valve to the next as long as you aren't moving the valves.
In your picture, one line is probably the output from pump to the loader valve, the other is probably the output from the loader valve going back to the 3 point hitch and/or your rear remote(s).
If you disconnect the line that has the fluid leaving the loader valve and going to the 3 point, you can put your backhoe lines there (loader valve out to backhoe valve in. Backhoe valve out to 3 point in).
That way the fluid flows from the pump to the loader valve, to the backhoe valve, to the rear remote (if equipped), to the 3 point valve, to the transmission sump.
If you put a tee in there, it will take the easier of the two paths every time and you will not accomplish any work.

" it will take the easier of the two paths every time" EXACTLY it was so bad I thought I tapped into two return hoses.
Aaron thanks for the explnation as I didn't know what I did wrong. I got ZERO pressure from the T it was worse than from the rear remote with it engaged.
After that I got frustrated and it was taking too much time for parts to come in and not knowing AGAIN which ports to tap into I cried UNCLE.

I was also afraid my block was maxed out. Front end loader, Grapple, 2 rear remotes.

Sorry to hear you gave up on your L system. There is a simple solution w/o buying a bunch of new stuff. K puts BHs on the Ls all the time. Any reputable K shop knows how to do that chore as the BHs are dealer installed usually unless special ordered. Wish I was closer; pay my way down there and we can figure it out. Do you now have the right manual or decided the one you have is the right one. In hind sight I wish I had thought to tell you to get the K regional rep in the act. I am sure they have a tech bulletin for dealers to show how to do it right. The bungee cord is not the factory solution.

I did look at the diagram again, alas non of the three valves have a detent position. On most valves a detent can be retrofitted into a valve. You would probably have to go to the valve manufacturer for that info and parts. K is probably no help because they want to sell their BH. To adapt the AM BH it would need to have a valve assembly that is or can be made a power beyond valve. Then the connection would entail 3 hoses.

All too late now. But others contemplating this procedure may be interested. Bottom line: have a remote valve that has a detentm or get the BH w/a PB valve system.

I only have 2 dealers with in 100 miles. The closest one I won't use because years ago he did the old quote and switch on me. Quoted me one price and I signed and confirmed that price then when it ws sone he said" Oh by the way we needed to do this and that and now the price is double" I said nope I agreed to this and if it was more you should have called me. I said I'm not paying he said then you're not getting your tractor, I said see you in court. He lost in court.

Next dealer first said $1,200 for a "valve" I said it has a valve and doesn't work on the valve, then he said nope can't be done.
