Thanks to EVERYONE for your input. So for simplicity sake if I'm absorbing all this info correctly, the easiest would be the quick couplers attached to the curl line. Which would disable the curl while the splitter was attached but I should still be able to raise and lower the bucket to move the tractor. As far as the return to tank line, I guess I need to determine what loader spool I have. If the port on top of my spool that I pointed out that is not in use is in fact a tank return I could plumb the return line with a quick coupler back in there? Correct . No extra valves or anything before the splitter? Thanks again everyone. If PTSG is correct on my output of 16GPM at 2500 rpms, is this going to be worth it, I like to run the tractor around 1000 rpms, or does the front pump rotate at a different rpm than the engine tach?
