Don't forget you can't just add a PTO pump. You will need a Reservoir to hold the fluid, And it will need to hold enough for the system to work.

The standard PTO pump supplied by <font color="orange"> Kubota </font> and Woods has a Output of 6 GPM.
Your tractors hydraulics has a output of 6.4 GPM. Unless you get a larger pump than standard you will not see a increase in speed. To install a PTO pump you will also need a reservoir for pump to suck oil from.
One item that I have not seen mentioned here, is 3PH fully lowered or bypassed on your tractor?

How are the backhoe outlets plumbed? It should be plumbed so that the backhoe inlet comes off the loader's power beyond and the backhoe outlet goes back into the circuit.
Do you have to jumper the backhoe connectors on the tractor together when the backhoe is not connected? If plumbed as above then you must have to jumper.
Is the 3pt lowered (as it should be) or raised?
You only have so much flow. The bh valve design will go a long way in determining which function has flow priority.

I gonna have to get my memory checked /forums/images/graemlins/frown.gif
I was wrong about not doing three things at once, I can curl the bucket, bring in the boom and dipper arm in all at the same time just not real quick.
The Madref is right about the plumbing, it should go through your loader valve.

I have a B7800 and Woods 7500 BH with PTO pump. My dealer advised getting the PTO pump rather than connecting to the tractor hydraulics and I think he was right.
I have no problem controling 3 functions simultaneously and have not found that I have to run the engine at high RPM in order to get reasonable responsiveness. If I ever get expert enough with the BH to think it is too slow, I guess I can run at higher RPM, which will increase the PTO pump output.

Hmmm...good point, I must have blew right past the 3pt hookup. Mine is connected to a remote. Does the 3pt restrict flow?

My BH is PTO pump powered. I've often operated it at idle engine speed when working close to the house or near something that can easily be damaged. Usually has enough power to get the job done but it's just slow going.
Having the BH w/PTO pump setup has been good thing for me. /forums/images/graemlins/laugh.gif

Not technically true about <font color="blue"> plumbed off the 3pt hitch </font> . For your configuration, the hydraulic circuit was broken after the loader but before the 3pt. The inlet of your backhoe is actually plumbed off the loader's power beyond outlet and your backhoe's outlet is plumbed back into the circuit before the 3pt.
That is why you have to jumper the connections when you remove the backhoe, otherwise the 3pt will never work and the pump will stall out and probably fail because you no longer have a closed loop for the fluid to travel from the pump back to the reservoir tank.
