Gotta go buy a new battery for the JD tractor I guess.

Went to start it up yesterday to do some clean up work from plowing and
I think the battery was frozen. When it's as cold as it's been lately I
can usually get it to fire up by putting a small battery charger on it
for five or ten minutes to warm it up a little. This time however the
charger displays "Full" after about 1 second of trying to charge and
automatically stops trying to charge. Battery voltage is low though,
about 11.8 volts, so I know it isn't charged.

Hate this cold. I can deal with the occasional snowstorm but the cold
is getting to be too much.
