The tractor was a "Hoyt-Clagwell" .

The Hoyt-Clagwell (Fordson model "F" built from 1917-1926 ) tractor is probably located in the Hooterville Museum . ~ see below .
It was some form of old-time Ford. The Ford motor Company was the initial sponsor of Green Acres and naturally wanted to get their own products on air. Ford was originally a farmer, and the Ford company has long made Tractors and other agrarian implements unlike GM. Ford vehicles were used exclusively on Green Acres for that reason. Oddly Oliver is a brand of(now defunct) Tractor and I often thought that was the source name for the lead male character, who was seen driving a tractor while singing the theme song. No, Tractor used was a Ford or Fordson(agrarian division of Ford Motor Co)
