How to Troubleshoot John Deere 6120E Tractor Problems

Troubleshooting Tips

The John Deere 6120E is a powerful and reliable tractor, but even the best machines can experience problems from time to time. If you’re having trouble with your 6120E, here are a few troubleshooting tips to help you get back up and running.

1. Check the fuel level

The most common cause of a tractor not starting is a lack of fuel. Make sure the fuel tank is full and that the fuel line is clear of obstructions.

2. Check the oil level

Low oil can also cause a tractor to not start. Check the oil level and add oil if necessary.

3. Check the spark plugs

If the spark plugs are fouled or damaged, they can cause the tractor to misfire or not start at all. Remove the spark plugs and inspect them for damage. If they are fouled, clean them or replace them.

4. Check the air filter

A dirty air filter can restrict airflow to the engine, causing it to run poorly or not start at all. Remove the air filter and inspect it for dirt and debris. If the air filter is dirty, clean it or replace it.

5. Check the fuel filter

A clogged fuel filter can prevent fuel from reaching the engine, causing it to not start. Remove the fuel filter and inspect it for dirt and debris. If the fuel filter is clogged, clean it or replace it.

6. Check the injection pump

The injection pump supplies fuel to the injectors. If the injection pump is not working properly, it can cause the tractor to not start or run poorly. A qualified technician should inspect the injection pump and make repairs as needed.

7. Check the governor

The governor controls the speed of the engine. If the governor is not working properly, it can cause the tractor to run too fast or too slow. A qualified technician should inspect the governor and make repairs as needed.

8. Check the electrical system

The electrical system powers the ignition system, fuel injection system, and other components. If there is a problem with the electrical system, it can cause the tractor to not start or run properly. A qualified technician should inspect the electrical system and make repairs as needed.

9. Check the engine

If you have checked all of the other possible causes and the tractor still won’t start, it is possible that there is a problem with the engine itself. A qualified technician should inspect the engine and make repairs as needed.

10. Take your tractor to a qualified technician

If you are unable to troubleshoot the problem yourself, take your tractor to a qualified technician for diagnosis and repairs.
