The Tractors are characters in Cars.
Tractors are hard workers. They enjoy what they do, plowing through the fields on a nice warm day, and then falling asleep under the moonlight. But every so often they wake up to the sound of snorting and giggling trailing off into the distance, and they find themselves lying on their backs staring up at the stars. But they don't mind. It's actually kind of nice to get to sleep lying down for a change.
Tractors can be tipped when they hear horns honking of cars. They are located in Fillmore's Fields driving around and sleeping lazily only to be tipped by cars. In one part, tractors roam around. While in the other side, the herd is protected by Frank who knocks away cars who try to trip the tractors.
Along with Lightning McQueen, Mater, Sally, Sheriff, and Chick Hicks, Tractors can be operated by CPU's and be used like player Cars by the Pit Crew. This has happened with tractors many times on World of Cars, however, all they will say is "Moo" a few times, or say "Moo" many times, even in capital letters.
- They are car versions of cows.
