Remove it from the tractor and store it in a non-freezing location on dry wood boards. Do NOT store it on the concrete floor.
Either the battery has a dead cell, which will require you to replace it, or something is on pulling power from the battery. Disconnect the negative cable and leave it off overnight. If the battery is dead the next morning the battery is defective. If not, then find out what is pulling power from the battery. Ignition switch may be defective.
A storm has nothing to do with the battery going dead.
Either a bad battery, a bad stator, (it's like an alternator for small engines) or a short in the wiring somewhere.
The battery keeps going dead.
In most cases a battery drains by itself from not running the tractor. I've had it on a 4020 where the tractor set for a few months and the battery goes almost completely dead. If you think it's more than I'm tellin you here bring it into a John Deere shop to have the wiring checked.
You do not have to reset the fuel pump just because the battery went dead.
eather the battery has a dead cell or if it is farly new and was dead for a period of time in the winter will kill the battery and cause it not to charge.... or it could be the altinator that is bad and not charging
The battery in your key fob is going dead, or is weak.
Yes, that would definitely drain the battery.
The battery is dead, you are going nowhere so why take the handbrake off. But, if you insist, just connect a good battery to the dead battery and jump start the engine.
It's time to buy a new one.
As long as you keep them charged you do not have to remove them. A fully charged battery will not freeze, but a dead battery will.
