</font><font color="blue" class="small">( Do we know yet whether the question is Conglomerate, Manufacturer, Brand, Family, Model Family, or Specific model. (and even at that: Brand/model recognition or actual units produced)?
In the latter of both cases, I'd say the Farmall H (300,000, just under 400,000 or over 400,000 depending how exact exact model is) is hard to beat - probably even worldwide. Else, don't even have a guess. )</font>
The N series of Fords outsold the H by a 100,000 or more. I own an H, they & the M were the mainstays on farms all across the midwest & were part of the modernization of agriculture.
I agree the question is too broad & not defined, so I stayed out of it. But, it's a day after NYE now, so I can break my resolutions.... /forums/images/graemlins/wink.gif
'Most popular' does not really relate to hard sales numbers. However, 'tractor' would imply a single model or series at the most, not a brand or manufaturer of all sales combined.
As such, the Ford N series of tractors was revolutionary, sold by far the most units in it's day, and lasted for many years on the market. It still enjoys some of the most solid support & vast numbers of the machines _in use_ by users around the world - and that is over 60 years after it was introduced! As such, I would have to say that is the _most popular_ tractor in the world.
Most in demand these days is a John Deere 4020 diesel. List that on your farm auction sale, and you will agree it is a _most popular_ item in the USA. /forums/images/graemlins/smile.gif
If you want to talk shear production numbers, and not 'popular' exactly, perhaps some MF/ MH/ Eastern Bloc tractor has the most raw numbers of units sold of a particular model. I couldn't identify which tho.
