Control valve ?

[rambler]

You've got an interesting one there..... Generally these open center hyds do not work well with just T'ing into a line like that. The oil will flow to least resistance. Open center hyd need to be put together in series, which is what Power Beyond does. A T line makes a parrallel connection. Generally something doesn't work when you do that, like the 3pt or the loader - as oil can flow freely between, in your case, the loader & whatever you hook to these ports.

Now, does the tractor have a valve somewhere that will close off the loader valving? Then these ports might have been used for a backhoe, & you could either run the loader, or run the backhoe, but not both. If the loader is shut off, the bachoe would _have_ to be connected, and if the loader was 'on', you would _have_ to disconnnect these hoses. You would always need one item and only one with a valve block running off those set of ports.... While changing, the tractor would need to be off....

Now, that is just one posibility. This was cobbled together by someone who does not do hyds for a living, so it would take an expert to follow through & figure it out exactly. Also, the expert would have to (for liabilty reasons) replace those water pipe connections with real hyd connections. Water pipe isn't strong enough to handle 2500lb hyd spikes. I know, I know, people do it all the time - but it is dangerous.
