The high pressure line off of the main pump goes to a priority valve. There should be two lines off of the priority valve, one going up to the steering valve and brake valve, and the other going back to the rockshaft/SCV's. Disconnect the line that goes up to the steering valve and connect a hose to it, connect other end of hose to tow tractor's SCV, tie tow tractor's SCV lever back. This SHOULD work and give you steering and brakes, provided tow tractor is a Deere, wouldn't work too well with older IH or similar open-center system, as tow tractor's system would stay on high pressure. Sorry I can't be more detailed, but I don't work on too many 4-wheelers newer than the 40 series, and I know that the 50 series 4- wheelers had a few hyd. system differences. Make sure to take the appropriate precautions for towing, such as making sure the 8650's shift lever is in the tow position, make sure it has plenty of trans fluid, have the flashers on, take it as slow as possible, take a break every mile, and make darn sure this works before hitting the road. Plan on this being an all day job. I really don't recommend towing something like this that far, but I know what trucking costs and I know what it's like to be in a bind.
