Frequently Asked Questions
What should I do if the master warning light comes on while mowing?
Stop the tractor immediately, shift to neutral, and turn off the engine. Refer to your John Deere Compact operator's manual for the specific fault code and contact your dealer.
Why does the glow plug light stay on longer in cold weather?
The glow plug system preheats the engine for easier starting. On your John Deere Compact, the light may stay on for up to 10 seconds in very cold temperatures. Wait for it to go out before starting.
How often should I check the water-in-fuel indicator?
Check the water separator daily during operation, especially after refueling. If the light stays on, drain the separator immediately to prevent fuel system damage on your John Deere Compact.
Can I operate the tractor with the PTO light on?
The amber PTO light indicates the PTO is engaged. You can operate with it on, but ensure the attachment is properly connected and always disengage before leaving the seat.
What does the hour meter light mean?
The hour meter light reminds you that scheduled maintenance (e.g., oil change at 100 hours) is due. Perform the service as outlined in your John Deere Compact maintenance schedule.
Why is the air filter light on after cleaning the filter?
If the light remains on after cleaning, the filter may still be clogged or the sensor is faulty. Replace the filter with a genuine John Deere part and reset the indicator if applicable.
