I have a Kubota STV36 tractor.  It has two double acting hydraulic valves and one single acting.  (One of the double acting can be switched to single acting).

I have quite happily connected a flail mower which needs two double acting valves to it.  I can understand how this works, two hydraulic cylinders with connections at both ends, push the lever one way and it goes one way, push the lever the other way and it goes the other way.

However I'm now looking at using a hydraulic log splitter with the tractor and that says "The log splitter has been designed to have a constant flow supply and a free-flowing return".  How do I provide this?

I have to day that there's very little practical information about tractor hydraulics that I can find.  My STV36 manaul tells me very little that's useful and the log splitter manual is just as bad.

I *think* what I need to do is connect a pair of pipes from one of the double acting valves and hold the operating lever in one direction so the oil will flow out of one pipe and back down the other.  I assume that the log splitter itself will have a way to use  this flow with its own spool/control valve.

Have I got this anywhere near right?  ... and is there anywhere with good explanations of this sort of thing?

SO log splitter pipes go on same double valves one in top one in bottom then the lever in the tractor is kept open  ( we used a  piece of inner tube to hold back ) and the lever on the splitter controls up and down
