I guess you could wire up the #1 terminal to the starter-solenoid as long as you put a diode in the line. If you don't have one laying around, you can buy a 3 amp diode for around 75 cents at Radio Shack. But . . . you will only be sending current to the field when the engine is cranking - so I suspect the alternator won't be turning fast enough to start charging until the engine starts - and at that point - you won't be sending field current anymore. It's a 15 minute job to install one of those self-exciting regulators into your alternator - but they probably cost $20-$30 - I haven't checked lately.
In regard to the diodes, I use them with most of my alternator hookups even with a key-switch, to prevent backfeed into the ignition circuit. I just recently put a Delco 10SI on my Case 580CK diesel - and it woudn't shut off until I put the diode in. But, if I had left it with the manual shut-off on the injection pump, I wounldn't of had the problem. I had installed an electric shut-off solenoid - and that's why it suffered from backfeed.
Hey - come to think of it - does the tractor have a headlight switch? Hook the d*mn field to that.
