JD400G major hydraulic leak
New here, recently purchased jd 400 g,late "80"s model. starts right up after we put new batteries in it and hydraulic fluid, started test driving and fluid went to poring from under it, Seems like the return hard metal line has a major hole in it, Any ideas what is the best way to repair this, This line is no longer available from Deere, Can we modify it some way and use a flex braided line, Whats the working pressure of this line? Any help would be benefical, Also is this commom?

Welcome to the boards.
Depending on the size of the areas needing repair and skill levels available some have patched those hard lines by brazing or welding. Replacing with a hydraulic hose is a commonly practiced option. If replacing with a hose, you need to keep the hose ID the same or a bit larger than the hard tubing ID. It is best to use the common braided two wire or spiral four wire hydraulic hose to replace the hard lines. The good hose provides more safety factor against wear and possible damage, even if not required for pressure. Route carefully and secure the hose well.
