Up here in western Michigan we just broke a 119 year old record for the amount of snowfall in the month of November.

Dean I figure just the opposite.  Since the average yearly temperature has 
only varied by a degree or so over all of the years of recording weather 
records, 
I figure if it's unusually cold early that it has to be warmer at some point 
to keep the 
average in line.  I guess Al Gore would equate that to mean a blazing hot 
summer 
but I figure the winter will be moderate to make up for the cold fall. 
Wishful thinking I guess. 
Time will tell.

Dean, 
Being prepared is good!  If it's this cold now then the winter might be one 
of those unusual cold 
ones.

The real art of conversation is not only to say the right thing at the right 
time, but also to leave 
unsaid  the wrong thing at the tempting moment.

Thanks for all the good replies, gentlemen.  Consensus certainly seems to be 
that I can just charge the two batteries together as a single 12-volt 
battery. 

My purpose in all of this is to keep the batteries charged and the tractor 
ready to start on cold mornings this winter, when I need it to clear snow 
from the driveway.  I have both 6-volt and 12-volt battery tenders, and 
enough of the quick-disconnect harnesses to put two on the 620, one for each 
battery, so I could use the 6-volt tender there and leave the 12-volt tender 
on the Super M (which has been converted to a 12-volt system).  Or I could 
put a single harness on the 620 by treating the two batteries as a single 
12-volt, and then just move the 12-volt tender back and forth between 
tractors now and then.  From the discussion here I believe either approach 
would work. 

I haven't had any trouble with the 620 batteries, but it's unlikely to get 
many long-duration periods of use over the winter, mostly short-duration 
work, so lots of cold cranking to start and not much run time to recharge 
via the generator.   I have to say I was pleased that it fired right up last 
night when I went to move the brushhog to a better winter-storage location; 
the weather's been way cold for this time of year, single-digit temps or 
nearly so every night for the past few days, and I hadn't run the tractor in 
a couple of weeks.
