Buck and Doe
These John Deere tractors reside at the Piston Peak National Park in Planes: Fire and Rescue.
These tractors are basically carified deer, with their roof lights resembling antlers. They are also a literal interpretation of John Deere, the tractors' manufacturer. Ironically, even though the deer are carified, the deer on the John Deere logo on their grilles isn't. Even ironically, everywhere else tractors are portrayed as carified cattle. A similar dilemma exists with the fact that both combine harvesters and bulldozers are carified bulls.
