[AT] Better build a bigger shed

[Jim Becker]

A near copy of the other chart on that page (horses vs. tractors) is also in the USDA yearbook.  I started looking at the references, finally noticed the connection.  The EH web page has this reference:

Gray, R. B. The Agricultural Tractor: 1855 – 1950. St. Joseph, Michigan: American Society of Agricultural Engineers, 1954 (revised, 1975).

The relevant chapter in the 1960 yearbook, “The Development of the Tractor”  was written by E. M. Dieffenbach and R. B. Gray.

So it goes back to the same source data but was updated over the years.

Interesting.  Pretty similar to the one I was looking at, but different enough to suggest the data was separately gathered.  Mine came from the USDA yearbook 1960, Power To Produce.  Thus the chart stops at 1958.  Where did yours come from?

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.

 

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.

Speaking of a billion tractors... Does anyone have a handle on how many tractors have been built in the world in the last 120 years? 

I'm not too sure where you would draw a line between "tractors" and "garden tractors". Parts of the world do a lot of farming with larger two wheel tractors.
