My understanding of the M59 hydro, is backhoe removed, no flow to the backhoe ports.
The kubota 3-valve remote kit, are all spring to center levers, so you can't use them as-is to drive a power beyond type need.
You might have to rig something up so the lever is held into position for full flow.
All of this PITA in getting a continuous flow out the rear of the 59 lead me to getting a chipper with self-contained hydraulic system.
Can't seem to get a straight answer from any of the Kubota dealers. 
My dealer is telling me that all three connections have to be made in order to prevent back pressure from damaging the hydraulics. He suggested they tee off of the power beyond from the front loader to the back for the chipper.
Another Kubota dealer is telling me that the Return Hose (white) is just a sump line and no pressure (not sure what that means) and that connecting to the Swing inlet hose (red) and Inlet hose (blue) is all you need for the chipper feeder to work.
I wish I knew the correct answer here. Is either the Red inlet hose or the Blue inlet hose a power beyond?
Just me rambling.
Cheers,
Chris.

None of the back hoe connections are power beyond.
Is there just a single lever on the M59 that you switch for the hydraulics when you take the backhoe on/off rather than two like my L39? If so, then here is my suggestion. Use the swing pump (red) connection to power the chipper. Connect the return line from the chipper to the tractor return port (white) and also tee in the main pump connection (blue) to the return port (white). Leave the lever for the ports in the backhoe off position until you get the chipper setup and lowered. When you are ready to chip, change the lever to the backhoe on position. Your three point will not work with the lever in that position as the main pump is being dumped to tank, but you won't need it while chipping. The swing pump will be powering the hydraulic chipper feed. Move the lever to the backhoe off position when you want to lift the three point.
The main pump of the M59 has quite a bit of flow. Probably too much for the chipper feeder it would run too fast. This may be why the dealer does not recommend rear remotes as they use flow from the main pump. The chipper feeder probably has some sort of flow control for controlling the speed of the feeder. If it is just a needle valve, then if you slow down the feeder, it will be forcing the tractor to dump oil over the relief valve which will heat up the oil too much. If it has a priority flow divider, then it would dump excess flow to tank and you would be ok using rear remotes.

All it takes is a bungee cord.

Absolutely.
I also didn't know if it was using a standard valve stack and one of the 3 might be replaceable with a detent valve that could be easily placed into a full open position and remain there.

I have a BX62 without the hydraulic feed. The manual also covers the hydraulic feed and it sure looks like the flow control is a priority flow divider so there should be no problem running the feed off a hydraulic remote or the backhoe connections. If you use the backhoe connections, remember to connect one of the backhoe pressure sources to the chipper and tee the other to the return line if there are not independent vales switching the swing and main pumps for backhoe on/off.
