I would also call the backhoe manufacture's customer sevice they should have a circut layout for your unit .Or tell you there idea on how to plumb it in .It would be a good thing to do if the unit is under waranty.I will check out our unit and get a better idea of the exact way our's is ran.

So, in series means that I would follow the inlet hose into the loader valve and then run an outlet from the loader valve to the backhoe as the inlet. Then the outlet from the backhoe would run back up to the inlet of the pump.
What about hooking up rear remotes through the tranny top cover? How is this done? Do I need to get an unloader valve?

As far as the rear remote there are some listed at Newholland website under part's they have the whole tractor listed in microfish form you can acess at no cost .Just type in 345c there and your tractor loader is shown in detail with most of the part's you can buy.Hope this help's .It depend's on what year tractor you have 1988 to 1992 as to the part's shown.If you buy a remote kit new it has simple instruction's

Circuit goes: tank to pump inlet. Pump outlet to loader valve inlet. Loader valve outlet to backhoe inlet. Backhoe outlet to tank (or 3pt then tank).

Interesting, my 1963 ford loader hoe has a power beyond circuit on the loader valve from the factory. Maybe they went "cheap" by '67?
With all the options, listed there is still one not mentioned. Why not replace the loader valve with one that has a PB functionality built in? Then you can use the loader or hoe with out worry. Surplus center may have one that is just what you need. It would be in the $150 to $300 range.
Just a thought.

John_bud: I checked the manual again and you are right, there is a power beyond line shown on the diagram. Sometimes I can't see for looking. Thanks for pointing that out.
I checked our ford 19-388 backhoe today it has no power beyond unless it is in the backhoe under the valve's .We have three line's to the backhoe 1 from the hydraulic pump on the front of the tractor to the backhoe.2 one from the backhoe to the ford 730 front loader resivoir the loader frame is the hydraulic resivior.3from the backhoe to run the front loader. It has to have three line's so it wont build up presure on our unit.I still think if you talk to your Ford NH dealer the mechanic should be able to look up your unit's set up and then there would be no question's and may even save you some money if your's has power beyond.I also would check with the backhoe manufacture to see what presure and flow rate is needed.

That valve is configured for power beyond, no doubt about it.FULLPULL said:
You have a pressure inlet from the pump, a return to tank/reservoir outlet and a power beyond outlet that goes to the loader valve. You have the backhoe valve plumbed as the first valve in the circuit.
What?? This makes no sense at all.FULLPULL said:
Hey Mad. I'm thinking of this set up you are referring to with my L2800. Tell me if I am correct in my thinking. My hydraulic block has one line going to the loader valve, and two returning to the block from the loader. One of the two lines returning from the loader goes to the tank, and one goes to the 3pt lift. To do what you are saying, I just run a line to the rear with a QD and another line back to the block where it will dump into the 3pt or tank depending on which line I use from the loader. I then have to put a small loop to connect the lines in the rear when not useing a backhoe or woodsplitter etc. Is this correct? I seen this done on my brother in law's JD 4110 and wondering how I could do the same set up on my Kubota. This seems it might be a little risky if I should ever get my loop between the 2 QD in the rear caught up on something and it comes unhooked.MadReferee said:
I guess what i mean is that i was suprised to see three line's to or from the backhoe.I was expecting two just the presure and return from the loader valve.Goes to show how much i pay attention i had this tractor in six piece's to repaint and replace the clutch.Since the loader is being supplyed though the backhoe then to the loader you need that extra line from the backhoe for a return line.The loader has a return also.Man we got line's running every where on this set up.
