John Deere 970 Power Beyond Kit Problems

[Deck III]

Good afternoon everyone,
I have been searching this forum for answers on the Power Beyond kit I installed. I do not have a FEL on the tractor and plan on installing a dual valve in the rear of the tractor off of the PB. My problem is with the PB installed I do not seem to have control of my 3pt hitch. Any help would be greatly appreciated.

How do you have the system plumbed. What is the logical order of the flow? The 3pt valve should be the last valve in the path.

What kind of PB did you install in the FEL valve. Some PB adapters have a hex screw that screws in the PB port and blocks off the flow to the tank port. Other PB adapters, you screw the adapter in the PB port and it blocks off the flow to the tank port. If you did not install the PB adapter, the flow is just flowing to tank via the FEL valve tank port.

If the PB adapter is installed correctly, the flow will flow to the 3pt and than tank. If you want to install more valves, you interrupt the flow to the back and feed the new valves and then route the fluid to the 3pt.

Most tank port out flows go to tank, and can be teed in for convenience.

If it is like the 950's there is a pipe plug (that should of came with kit) that has to be put in. Check your manual. I can't explain just where it goes, just to long ago to remember.

Should be a 1/4 in pipe thread screw, or an adapter sleeve with a seal on the base. Prince uses both kinds of adapters. Should also use loctite on the pipe thread.

Thanks for the info., Hopefully the plug is the problem, will put it in and see what happens.

It was the plug, thanks for the info. really appreciate the help.

Thanks for answering back with the fix.

If it vibrates out, you will lose everything past that point. The FEL will still work.

Hello I'm new here...just read article having same problem. So were exactly does this little 1/4" plug go???

If you have the hex screw for the PB, then is screws inside the PB port. Use some Loctite red or blue to secure it..

Looking at all the valves, some of the valves use a PB adapter sleeve and others use the hex screw.

What this does is to separate the galleries so the main fluid will pass through the valve to another valve, and the cyl used fluid will go to tank. .

As an example, look at page 5, and 9
