Tractors

The Tractors are characters in the Cars franchise.

Cars
"The earliest domestication of the North American tractors can be traced back to the 1800s during the construction of the first continental railroad. Railroaders quickly discovered the tractors' ability to create level grades across even the most demanding geography. Today the native plains tractor is regarded as one of the true pioneers of the West."

"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."

They appear in Cars when Mater decides to take Lightning McQueen tractor tipping. They later appear in McQueen's dream of Frank winning the Piston Cup, when a stampede comes into Radiator Springs, and at the Radiator Springs Drive-In Theatre.

Mater and the Ghostlight
In Mater and the Ghostlight, Mater zoomed past some tractors in Frank's field when he thought he was being chased by the Ghostlight. Mater's screaming causes them to tip.

Unidentified Flying Mater
The tractors appear in Unidentified Flying Mater, where Mater takes Mator tractor tipping. Mater tips a tractor with his horn, then Mator tips all of the other tractors in the field with a louder honk that created a crop circle design.

Planes
In DisneyToon Studios' Planes, some tractors appear on the fields during Dusty's training montage. When Ishani is later talking to Dusty in India, a tractor passes them. During their journey to the Taj Mahal, they fly over a few fields full of tractors.

Trivia

 * Tractors can be tipped when they hear horns honking or engines revving loudly. In Cars 2: The Video Game, they are, however, easily tipped when you hit them. In Disney Infinity, they can be tipped by both ways. In Planes, some get tipped when Dusty flies past them during his training montage.
