email requests for this modification have been overwhelming, so I'll post it here:You block the path of the normal oil flow and divert the pressurized oil through one or more open center valve, then put the oil back into the 3-point circuit. Remove the cover plate (hand size) under the seat. Look at the two ports in the casting of the tractor and note that one is smaller with oil at the surface. If any doubt, touch the starter button and oil will come out of the pressure port. Identify which of the two ports into the cover plate this corresponds with. Tap threads into this and screw in a plug. I use 1/2" NF, but whatever works for you. Take the plug out and identify the corresponding port in the center of the cover. Just blow into it. Trace this path on the outside surface of the valve. On earlier models this is raised. You need to drill into the center of this and tap it with 1/4" NPT. Drill just into the passage, not through. This has to be done just right to be in the center of the passage and get good threads. Put a 1/4" elbow in this. Clean and blow out metal filings. Re-assemble with new O-rings. Remove the plug from the test port at the bottom of the casting. Run a hose from this port to the 'in' side of the open-center remote valve. Run a hose from the 'out' of the valve to the new 1/4" elbow. That's all. The 3 point and the remote valve(s) will work without moving levers, chaining lift arms, or changing connections. One caveat; you must have the valve in the circuit or alternatively run a hose between the test port and the new port. Otherwise you'll have the pump running against a plug...not good. If you ever want to return this to normal function just remove the inside plug and replace the new 1/4" elbow with a plug. I have a similar modification for 8N/9N that provides for remote hydraulics. Unfortunately, Mrs OTG dumped it when loading this new computer and I only have it on paper. About a year ago I emailed the how-to out to dozens of you on this bullboard. If anyone still has it, please send me a copy so that I don't have to re-enter it. I'm better with a wrench than a keypad. Thanks John, tOTG
