[AT] Of the 10 worst tractors, two were made by Fiat. 4 were from brands eventually acquired by Fiat.

I was unfamiliar with the Oliver 1250.  Tractor Data says 35 Hp for the Fiat made gasoline engine.

Fiat was selling in the US auto market in the mid sixties. I remember a little 4 on the column model. 

[Cecil Bearden] My experience of the worst was with a 1010 John Deere, and that Fiat made Oliver.    Both were just too small to compete with the 25 hp Massey Ferguson tractors we had before.
