I understand what everyone is saying about bad connections, bad wiring, worn brushes and so forth, but, if any of this was the cause, wouldn't it still occur even if the battery charger is hooked up?
Correct. If your tractor reliably starts with a jump start or with a top up from a charger but looses its charge if left to stand its almost certain its a duff battery. Last thing to check is fully charge the battery then disconnect one of the battery terminals and leave it stood for a day. If it holds its charge then you may have an electrical problem draing the battery. If it doesnt hold its charge, its a duff battery.
If you think youve got a drain from the light switch then do the above check.

I would still be looking at replacing the battery. A battery charger does not and is not meant to be a booster battery to start from as it only puts out a low amperage not enough to start off.
Try as suggested, fully charge the battery disconnect one of the main leads like the earth or positive cable let it stand for a day or two connect it back up and try a start up. If it does not start toss the battery and get a new one. If it does start you have a short somewhere that is draining the battery. It can be anything from the alternator to a switch or regulator and so on. That's when you need a meter and start testing for the leak.

Just for peace-of-mind, I haven't had the battery charger on it for 3 weeks. It's also stood idle for 2-3 days @ a time and started right up. Even on sub-20 degree mornings. A new battery is on the agenda for next week.

Thanks again for the help!!

Why a new battery? Battery sounds fine. Sounds like you may have had an issue a drain via the light switch??
