[AT] Generator--doing funny things

Sat Jun 17 07:03:43 PDT 2006

I understand that modern farmers are taking up knitting so they have
something to occupy their minds and their hands while they're operating
the equipment.  :-)

Larry,  our grandfathers and great grandfathers thought the same thing
about 
our  old tractors when they were new and replaced the horses.
Personally I 
like both the old technology and the new.
A friend of mine recently got re-married to a guy that tends 3500 acres
of 
cotton.

She was telling me about bedding up rows.   I quized her because I knew
that 
level of tractor operation was above what she knew how to do.  Then she 
explained that it was the new tractor with the GPS system.  Seems it has
all 
the fields they farm mapped into it.  All she has to do is drive the
tractor 
in the field and line it up with the line on the display.  Then it takes

over and she get's to turn it around at the other end of the field. 
Apparently the  thing never varies more than a inch from one end of the 
field to the other.

I don't know about you but  I never ran a row that straight.  grins.

Charlie
