I’ve just acquired a Teagle 8080 that I want to use on a 2140 John Deere, does anyone know what needs doing to the hydraulics to set them up for closed centre use? Cheers

Should be some info in the operators manual. A valve will need screwed in or out or fitted.

Not got a manual for it, haven’t looked at valve block closely to see if I can see anything, have done the wrappers in the past where a plug needed doing, just thought someone on here might know of the top of there head, cheers

Teagle have all the manuals on their website. Not sure what age your machine is but I found this.
There is a plug in the valve that needs changing.

Plumb the return to the plug on the base of the JD's filter housing, which will stop starvation of the hydraulic pump when using constant flow.

Have already got the spool return into the filter housing, as use this for wrapper and tub feeder. Just not sure what to do with the valve block, not sure what this third line thing is that is mentioned in @tweedale terrier posted manual? Have only ever needed to fit plugs to blocks before, cheers

Then you don't need to do anything to the valve block, just plug in the same as for your wrapper and feeder.

The third line return is what you have already fitted to your tractor.
Have you ever used one?

The return to the filter housing is what I have always called a free flow return (unrestricted) as supposed to going through the spool which could cause back pressure. Is this what they call a third line? As I still only have 2 pipes?? One from spool (pump) and one to filter (return) cheers

Yep. We run a 9090 on a 2130. The return is plumbed in to the filter return and there has been no modifications to the valve block. Never had an issue, works perfectly.

If you don’t set the valve block up for closed centre it means that the tractor pump is on full stroke all the time, which isn’t good for the pump or hydraulics on the tractor though, I know this “will” work as it is but like things to be right , can’t afford to break anything!
