Fuses are generally organized into "load centers." Key assignments often include: 10-amp, Horn 10-amp, Radio Power Supply F06/07–F06/12: 10-amp each, Work Lights (Front/Rear/Corner) 15-amp, Light Switch 10-amp, Windshield Wiper/Washer John Deere Wiring & Schematic Resources

For models with an operator's cab, the main fuse and relay boxes are located , just below the rear window. You can access them by pressing down the latches and lifting off the trim panel.

| Circuit | Fuse Rating (Amps) | Common Issues | | :--- | :--- | :--- | | | 15A - 20A | Blows if the starter solenoid shorts. | | Headlights | 20A | Check the circuit breaker (often a metal button on the dash or near the fuse box) if lights fail; fuses rarely blow unless a wire is grounded to the frame. | | PTO Solenoid | 10A - 15A | If this blows, the PTO will not engage at all. Check the PTO clutch coil for resistance. | | Cab/HVAC | 20A | High load circuit. Often upgraded by previous owners to 30A, which is dangerous and can melt wiring. | | Fuel Solenoid | 10A | Critical. If this blows, the tractor will crank but will not start (no fuel delivery). |
