<P class=MsoNormal><SPAN style="FONT-SIZE: 12pt; COLOR: black">Somewhat of a
SWAG, but there were about 4.8 million tractors in the US in 1960, exclusive of
garden tractors. Certainly many of the then 30 or more year old tractors
were already gone. So numbers originally produced by 1960 would be higher,
call the total 6 million. The annual production peaked in 1951, just over
600 thousand. It dropped off sharply after that. I doubt that as
many have been built in the 60 years since 1960 as in the 60 years prior.
Call it another 4 million. That puts total US production in the range of
10 million.<o:p></o:p></SPAN></P></DIV>

<P class=MsoNormal><SPAN style="FONT-SIZE: 12pt; COLOR: black">What about the
rest of the world? Maybe as many more as the US built? If so, that
would put total world production around 20 million. That has to be about
the right order of magnitude. Adding in garden tractors, and even deciding
what a garden tractor is will make a big difference.<o:p></o:p></SPAN></P></DIV>
