Do you have a relay that operates the starter solenoid primary current?
What do you mean by "solenoid ground terminal"?
I have never seen an isolated ground solenoid on a tractor.
The faint humming sound could have been the brushes on the comm or the starter windings.
Yes there is a relay that is functional and brings a live current to the solenoid. the solenoid has a large wire connection which is clearly hot with a large red wire coming in and one going out to the alternatorthe solenoid also has a small stud that(I think is neutral) which has two wires. one coming in from the relay and one going out to a stud mounted directly on the motor housing. the stud that leads to the motor housing was hot to the touch but was not hot on the motor housing stud.
