The tractor seems to be a very famous one... Fordson
Sorry to disagree, but that's not a Fordson tractor. I don't think you'll find a Fordson with the engine enclosed by a louvred cowl like that.
It's a McCormick-Deering 10-20, a model made from 1923 to 1939 by the International Harvester Company. The one shown below has different wheels, but you can see it's the same machine.
