Hydraulic top link

[Robert F.]

I have a JD 2305 with a backhoe which means that In also have the power beyond installed. Can I use the power beyond to power a hydraulic top link. If yes, what would I need in terms of an actuator?
Depending on responses, I will have more questions.
Thanks. Bob.

Sure. You would need to plumb a valve in series on the PB line. Plenty have done it (myself and a few other with 2520's). Cost will be about $500 by the time you are done...And you need to decide id you want it permanently mounted or temporarily when the hoe is removed. Either way you will need to fabricate a mount yourself.
If your still up for it, I can link some threads...

Probably would want to remove it when the hoe is on.
Still up for it, links would be appreciated.
Thanks.

OK, here are a few:

Mine
Jim's
Brad's

So in a nutshell:
Buy a valve, then design/fabricate a mounts for it that in a convenient place and can be easily removed. Next measure the length hoses required to "plug in" to the PB loop that you have, you will need the matching QD's to do this since your valve will be removable. Then measure the length needed to get to the HTL cylinder.

Kennyd the pictures of you just 5 years ago shows you are very knowledegable on hydraulics for just a teenager!!!!

Nice!

Thanks for all the replies.
I know that I would need a valve that the power beyond would connect to and would be connected to the cylinder. There are many different kinds of valves. What type of valve would I need?

This should work;

I would recommend a two spool valve so you can add a tilt or something else later on.

There inlays the problem my friend...to use a PB equipped valve, then you need a tank port on your machine-and there is none. That is why myself and the others I linked to did not use a PB valve.

Someone will mention soon that your valve will blow up-but cannot explain why backhoes and 3PH splitters work OK.

Agree...add a two spooler for sure!

Thanks for all the replies.
The cylinder and valve are on order.
There was a post recently by kennyd about which port on the John Deere block is the feed and which is the return. If I remember correctly, it is the rear most port=feed and front most=return. I can't find that thread so I cannot verify if that is in fact what Kenny said. On my 2305, that would make the feed on the power beyond be in the hose with the male end. My experience is with air rather than with hydraulics, in which case the feed is always in a pipe or hose with a female end.
I believe that it will matter to the valve which is feed and which is return so I need to identify which is which.
Do I remember your post correctly or am I mistaken.
How can I identify which is which without the shop manual for the tractor?
Thanks.

Sorry Robert, I don't think it was me. I am not sure on the 2305 which is the OUT and IN ports, and it DOES matter. The bracket that held the PB QD's on my 4110 where marked IN and OUT.

Thanks Kenny, you are right, it wasn't you, it was Jim whose pictorial you sent me. His is a 2520 and has the same loader valve as mine but the block where the PB lines are connected is not the same. On mine the hoses come out from the top rather than from the bottom.
I am bringing the tractor to the dealer for a replacement of that crappy seat that comes with a 2305 with backhoe so I will ask the mechanics which one is the feed. When operating the 3pt hitch, one of the hoses moves a bit while the other does not. Also, with my hand on the hoses while operating the 3pt, I can feel a slight pulse in one of the hoses but not in the other so I am assuming that the active one is probably the feed.
Thanks for the help. Bob.
