Alright, I'll give it a try.

Ok, put an extra shot of Marvel in each cylinder just to make sure things are nice and free. Ran an extra ground to the starter mount. Jumpered right to ground bolt and + on solenoid. Still getting the voltage drop.

v drop across solenoid? or where? at battery? or?
on a 12v system, you should really not drop below 9v cranking that type of tractor, 4.5v on a 6v machine. Ideally those numbers would be 10/5 .

I tried what we discussed, jumped straight to solenoid and ground bolt to eliminate the batt wires.

No, where are you seeing a voltage drop. Ie, where are you measuring across with your meter.

I'm clamping the leads under the jumper cables. Batt side of solenoid and ground bolt.

ok, so you are measuring battery hot to ground.
what are your measurements?

Yes, exactly. Before cranking ~13.8VDC, during cranking ~4.3VDC. If the starter was "bad" (We know it's not dead, it spins), do you think it could drop the voltage like that? Maybe it's working so hard to try and turn the engine that it's drawing all that amperage?

I didn't mention this before... With the plugs out, I still see the voltage drop, not quite as much, but significant, and the motor turns until I let off the starter push button. With the plugs in it makes maybe half a revolution (I'm viewing the back of the fan sitting on the tractor) and then bogs down. I don't have a compression gauge, I was going to see if maybe AutoZone rents them out to check it.

um... I'm seeing either an error in method doing the measurements, a damaged meter, or a very bad battery.
A standard car battery, you should be able to clamp a meter to the posts then short it with a piece of rebar and NOT go past maybee 7.5v, but would have arcing, sparking and melting going on.
so to see 4.5v dc at the battery hot cable either means bad battery, or bad cables / terminal ends, bad meter, or wrong measuring technique.
Also.. curious.. bat static voltage should be only 12.6.. it will be a little higher right after charging, but should drain off the high charge in minutes to 12.6.. a battery setting at 13.8 is kinda odd.
