Decoding the Color Codes: Understanding the Urgency
John Deere utilizes a color-coded system to communicate the severity of issues:
- Red (Critical): Immediate action is required. Continuing operation could cause serious damage or injury. Stop immediately.
- Amber/Yellow (Caution): Addresses a potential problem requiring prompt attention. Operate cautiously and address the issue soon.
- Green/Blue (Informational): Provides status updates and generally doesn't require immediate action.
Common John Deere Tractor Warning Lights and Their Meanings
This section provides a general overview; always consult your owner's manual for model-specific interpretations.
