How to Fit Front AND rear hydraulics to a Kubota l2501 tractor simultaneously

This is a narrow, practical fix for a specific plumbing question: how to run both front hydraulics (grapple) and a rear backhoe simultaneously on an L2501/L2520 by looping the open-center circuit and adding a cheap three-eighths to one-quarter inch adapter. It's a short, informal explanation with no footage of the implements running, aimed squarely at owners who already have both attachments and are confused about the hose routing.
