A book could be written on this! Conductive dirt, debris or brush carbon in the starter, generator (or alternator, if converted), voltage regulator, or ignition switch can slowly drain the battery.

Also, if there is wet dirt under the operator's platform, and the battery cables have any damage, that can contribute to draining the batteries.

If it is set up "as-original" the RH battery has it's (-) side grounded to the tractor chassis. It's (+) terminal is connected to a stud in the engine side of the starter "belly", keeping the starter's internals at 12-Volts all the time. Also, the generator's internals are "HOT" all the ime, too. That's where the current drain usually occurs. TYPICALLY, this is the battery that drains while sitting unused.

If you disconnect that battery's (+) cable between uses, you should be able to get through the cold weather without the battery draining, and then throughly check out the starter and charging system in better weather!
