to Bob M I have a 53 farmall Super C I leave the tractor sit for 2 weeks at a time and when I come back to use it the battery has drained. I had been disconnecting the battery ground cable to keep that from happening. however in my searching I found out the generator needed polarizing. Then I was told if Ikept removing the battery cable I would have to repolarize the generator. What is your advice. I do have a trickle charger but during the 2 weeks I gone I have no electric. Once I return I turn on the electricity and plug in the trickle charger It charges up the battery. what do you advise?

1) How old is the battery?
2) Have you considered a solar trickle charger?
3) Have you checked the fluid level inside battery?

No need to polarize. A working system has no current to the generator when not running, same as disconnecting the battery. I would be looking at what is draining it.
Just a thought, but it could be one of the contact points in the voltage regulator sticking. I've had that happen before. So once you shut it off, you may be able to see a spark as you lift the battery cable off the terminal, caused by the load on whatever is drawing the juice. Take the cover off the VR and see if one of the contacts is stuck, maybe push them apart with your fingers and see of it stops the arc at the battery terminal, if you saw it when you pulled it off.
Just an idea

You only need to polarize a generator once. Unless the generator is removed and disassembled - or suffers a direct hit by lightning - a generator will not need to be repolarized again. Removing a cable from the battery when shut down will NOT affect polarization!
Does the battery go down when the ground cable is disconnected? If yes then the battery is failing and should be replaced.
However if the battery stays up, it's a parasitic load in the tractor electrics that's drawing it down. Assuming your Super C is wired correctly about all that can cause this is a failed voltage regulator (specifically the cutout relay has stuck closed).
Best fix is a new regulator. You can fuss with the old one by cleaning the points, etc. But if the relay has stuck once it WILL stick again!

Get a 20-0-20 ammeter & when you take the battery cable off of the
battery post, put the meter between the post & the cable to read
the current draw.
Something like 5 amps or less is probably a bare wire in the
ammeter/ switch department under the steering wheel. I wish you
luck if the trouble is in there---cramped quarters.
If it is on the order of 15 to 20 amps, it is probably in the
gen./ regulator area, as others have noted.
Could be in one of the lights/ wiring. Not too likely, though.
Best is to start disconnecting wires---start by removing the
batt. wire from the regulator to see what the draw is at that
point.
