Nita--Your tractor battery will run the inverter fine.
Be careful to check and look for the + (positive) on the battery and wire it to the + on the inverter, it is normally the tip.....the connection on the side of the inverter (if this is a cigarette lighter plug-in type) is normally negative.
Also, be sure the battery is full of distilled water, if it is a non-sealed type. In an emergency (like you are in!) you can use whatever water you have at hand. Just be careful, that's strong acid in the battery.....
Keep us posted.
Prayers UP!
(Thank God you're BOTH safe)
