I agree with most everyone else. The battery is the last on the list of possible problems if it is fully charged and the specific gravity is good, but since the cables are warm, the battery obviously has the juice to produce the power to heat the cables.. As everyone has said...

1. Check for proper wire size and make sure the connections are tight and clean as possible and the ground is on a solid piece of framing, or casting. No sheet metal connections for the ground please =)

2. Check the starter, as was stated if the bushing are worn, internal parts, armature and field, can rub each other and cause the starter to dragg something fierce and pull abnormally high current and eventually burn out the starter windings, not a good thing. Bushings can be redily had and replacing them isnt too difficult if you observe how you take the starter apart.

3. Theoreticllay the solenoid contacts could be going bad and basically causing a bad connection. About the only way to tell is to either replace the solenoid with a known good one, or use a GOOD ohmeter and check the contact resistance. If your tractor has the push button switch with the main cable going to that ( I think some did, I dont know much about the letter series), then the switch might be bad. You could use jumper cables to bypass the solenoid/switch.

4. Chances are the battery is ok, but not necessarily. Make sure it is charged good, the specific gravity is good, and the voltage is good (might have a dead cell). Also do a load test on it after it is fully charged.

Hope this help to combine all the other posts for a easier time troubleshooting.
