"It does show the two coils in opposite polarity, presumably if the motor starts and over-revs the starter, or even if the keyswitch is released, the second coil should disengage the starter as the power feeds back into the first coil."
Kevin, Kevin, Kevin! As a "fixer" this shouldn't have been the first time you've seen a starter solenoid with two coils, a "pull-in coil" and a "hold coil"! Typical starter solenoids are made like that.
You are reading WAY too much drama into this... the "pull-in coil" is in series with the starter and draws a lot of current /provides a lot of magnetism to initially pull the solenoid closed, then is switched out of the circuit once the solenoid contacts close. The "hold" solenoid winding remains energized as long as you are cranking the engine, and is able to hold the contacts close with a lower current draw than was needed to close them in the first place.

If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
