Donnie, like Rockyridgefarm said, you can't move the thread to another forum, but any of the moderators can. Maybe some of the other moderators might see things differently, but I don't see anything wrong with it being where it is.

To me, Ron & JR are saying the same thing.
Power Byond valves are special, that they each take pressure from the pressure supply hose, but don't take it all away so other valves lose pressure - if any valve loses pressure, that implement would drop.
Each PB valve dumps it's low pressure back to the resovoir so as not to have back pressure. You can share this hose, but not in a way to apply pressure between valves - only all to drain.
Kind of like hooking up batteries in parrallel or serial - you get very different results if you do it wrong! /forums/images/graemlins/smile.gif The high-pressure side needs to be in serial, while the low-pressure return line needs to be in parrallel.
I think.

Just what I thought. That does make a difference. /forums/images/graemlins/wink.gif
If I understand all this correctly, you take the PB hose from the original valve loose at the tractor; not from the valve, then run that hose from the PB port on the original valve to the inlet port on the new valve, then run a hose from the PB port on the new valve to the tractor, where the original PB hose was connected. Then of course you need to run a hose from the outlet port on the new valve to wherever the outlet hose from the original valve is attached, probably by putting a tee in the line from the outlet port on the old valve, so the outlet port on both valves is now going to the sump or reservoir.
I think that's the way to fix what we're talking about if I'm not confused, too, by now. /forums/images/graemlins/laugh.gif

I believe you and I are saying the same thing. /forums/images/graemlins/wink.gif I was explaining how to hook up valves if they are mounted next to each other. Donnie may be mounting the valve on the fender or ROPs like others have done for their Top and Tilt. There was a link to a backhoe manual that explained how to hook an additional PB valve. I could not find it when I looked for it. The Link was to Bush Hog, I looked under backhoe manuals but could not find the same page that was linked in the Tip and Tilt Thread. Maybe someone else can find it.

Yep, I'm just not sure whether either of us explained it so that everyone else knows what we're talking about. /forums/images/graemlins/wink.gif Their fault; not ours, right? /forums/images/graemlins/laugh.gif

A progress update: After going through many dealers and sales people, I think I have finally found the kit I need to get hydraulic pressure to the rear of my tractor. Here is where it gets interesting. I was searching for a power beyond kit for my tractor and was told numerous times that one did not exist. Well a "power beyond kit" for the JD 970 does not exist. However, an "alternate rear hydraulic kit" does. And guess what, it is listed under the same number as the power beyond kit for the JD 990. So for the JD 990 power beyond kit you order complete goods kit bm18010 for $190.00. For the JD 970 alternate rear hydraulic kit you order complete goods kit bm18010 for $190.00. /forums/images/graemlins/confused.gif
I found this information out by not telling people that I wanted to add the basic equivalent to a top and tilt kit - this just seemed to confuse the situation. I told them I had purchased a JD backhoe and need the hydraulic hook up for it. The same JD salesman who told me a "power beyond kit" did not exist, called me back later and told me the "alternate rear hydraulic kit" was what I needed to hook up the backhoe. I went to the JD web sit (specifically the JD configurator) and found out that the complete goods part number was the same as the power beyond kit number on different tractor models.
So, is anyone confused yet? Good, because it seems you have to be confused and frustrated to figure all this out. I do not know if there is a lesson to be learned here but I do hope this information will help someone else avoid the time and frustration I have been through to accomplish what would seem such a simple task. Now I just have to hope that all this works.

drichards, for closure and edification we need a picture of this gizmo and exactly where and how it hooks up /forums/images/graemlins/confused.gif

drichards, I farm for a living, mostly older equipment, do my own work, and have 7 different colors - er, brands - of machinery.
Welcome to my world. /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif Most of the time I need the parts, as rain is coming & $10,000 of crop can be in the balance. And I get to do the same tap dance. /forums/images/graemlins/smile.gif
The lesson is - persistance.
Valuable lesson when dealing with a mix of lawn & farm dealerships that don't always overlap in knowledge. Many a time I ask for things and am told it doesn't exsist. Usually it's sitting on a back shelf. You learn which of the parts guys to talk to (the busy one - who knows what's going on!) and how to ask the question to get the right reply.
I wanted a disk spool (part that holds the disk blades apart) one day, the parts kid said they didn't have any that old. I pointed to the dried flowers arrangement on the counter. The 'vase' they were using was the cone I needed.

When it comes in and if it appears that it is going to work, I will document the process with plenty of pictures to share the new knowledge. If it doesn't work I guess I will share that too because I will be at the 10 point of the frustration scale.

Thanks for the smile. I am glad to see that my trials are not unique to this world. I just wait for the day that I can recognize the "vase" for what it really is. /forums/images/graemlins/tongue.gif

Rch: The kit has finally arrived and I hope to have it in with in the next couple of days. From reading the instructions all this kit appears to do is to tap into the pressure side, for pressure, and into the return side, for a return flow. When the rear hydraulics are not being used, there is a hose that connects the two. So, I assume that this will create a continuos flow of hydraulic pressure or flow - or simply it will be diverted out of the hydraulic system through a new line and then returned back to the tank with a new line.
Now, here is where I am still confused. Lets say that kit is installed, and I take the pressure line and run it into the new valve. I put this line into the "in" portion of the new valve and plumb the out portion of the new valve back to the return of the new kit. In my theory this should work. However, there is still the other opening labeled "PB" that I do not know what to do with. I am thinking that this could be plugged off and not used. I thinks that I would use this if I wanted to power another spool/valve in which case I would just T into the return.
Am I close, am I on the right tract or am I just sleep and hydraulically deprived?

Please read over my post that explains what the 3 ports are for.

The PB port can be plugged. But it requires that original PB fitting be removed and a special plug be put in its place.
