The tractors are cattle that reside in Radiator Springs, under custody of Frank. They act similarly to cows, and roam the fields in Ornament Valley day after day, consuming grass and plowing fields. While most tractors in the series remain nameless, some have been given unique names, such as Rusty in Cars and Betsy in Planes: The Video Game.

They are voiced by Steve Purcell (although they do not speak).
