That helps!
Here is as link to the parts manual for your tractor.
Put in the model and serial numbers as you have shown.

Scroll down to 5 lines up from bottom (769-01652E)
Page 39 has your wire diagram.
The relay mod that Oak suggested will not help you because your solenoid is not incorporated into the starter motor, it is external.
So two possibilities are your problem:
1. You tested the solenoid and probably assumed it is good because you heard it clicking. But if the contacts inside are burnt/corroded, it can operate but not deliver full current flow to the starter (i.e. low voltage).
2. Your starter has a problem as you suspect (i.e. shorts, burnt brushes, etc.) You can't read correct voltage across a short.
So unless you have spare parts laying around to swap, you gotta make a decision on where to start spending money. Solenoid $10-$15, starter $50-$80.
Or you can open the solenoid up and have a look at the contacts and decide from there.
