The John Deere tractors put their main brake and parking brake synchronized to each other. When the parking brake is Off, the primary brake pedals work freely. It means you can manually stop and run the tractor by pressing and releasing the brake pedals.
When it comes to the parking brakes, there is the main pivot shaft directly attached to the brake pedal. It is a long rod that holds the brake pads or calipers connecting to the wheels. There is a metallic block attached to the main pivot shaft.
Just on top of that is the location of the parking brake engagement shaft. Therefore, when the parking brake is on, the shaft falls down and locks the brake pivot to a stand-still position.
