Here’s What John Deere Tractor Warning Lights Mean

  1. When a red “STOP” light flashes, it indicates a serious malfunction and one should turn off the engine immediately. In addition to the flashing red light, lights 7, 8, 9 or 10 will indicate the specific malfunction that has occurred. It is important to follow these guidelines and take appropriate action for safety purposes.
  2. The yellow “CAUTION” light is an important tool for drivers. When indicator lights 7, 8, 12, 13 or 14 come on simultaneously the light flashes to warn the driver of a potential issue. It can also mean that the handbrake is engaged while the engine is running and gears are engaged. Indicator light 6 should also be illuminated in this situation. To turn off both lights all a driver needs to do is disengage their handbrake.
  3. When something is amiss with an electrical part related to the hydraulic system or transmission, this light will flash. It is imperative that the tractor be brought in for servicing without delay. Failure to do so may result in further damage and necessitate costly repairs.
  4. When the key is turned one position to the right on tractors with AutoPowr transmission only, a light will come on. It is important that users wait for this light to go out before starting the engine in order to ensure proper function. Failing to do so may cause unanticipated issues and damage machinery.
  5. When a hazard light indicator is illuminated, it’s an indication that there may be an obstruction in the road ahead or some other type of potential danger. It can also be used to signal to other drivers that one needs to slow down or stop due to an emergency situation. Proper use of hazard lights can help keep everyone safe on the roads and should always be respected when seen by other drivers.
  6. The handbrake of the vehicle is engaged and the engine is running. In some models, there may be a warning sound to alert the driver that the handbrake is on. It is important for drivers to ensure they have safely applied their brakes before taking off in order to avoid any potential accidents or damage to their car.
  7. If the driver notices that their engine’s coolant temperature is too high, they should shut off the car immediately and take it to a mechanic for service. It is critical that they do not continue to drive if the Stop light is on as well, as this could lead to overheating which can cause significant damage or even total engine failure. Taking immediate action to cool down and check the engine will help ensure optimal performance going forward.
  8. It is of utmost importance that your transmission/hydraulic oil temperature is serviced immediately if it is too high. If the Stop light is also on, shut the engine off without any delay as this indicates a critical situation. Professional assistance should be sought for in such an instance to ensure safety and optimal performance of the vehicle.
  9. The transmission/hydraulic oil pressure is too low and needs to be serviced immediately. If the Stop light has also illuminated, it is critical to shut off the engine IMMEDIATELY. Delaying service could result in severe damage or even cause an accident. It is important that this issue be addressed without delay for safety reasons.
  10. If the engine oil pressure warning light illuminates while the engine is running, it should be shut off immediately and the oil level checked with an oil dipstick. Depending on what is found, additional oil may need to be added or a full oil change might be necessary. If accompanied by a Stop light, it’s critical that the engine be quickly shut off.
  11. This tells you when the headlights are on high beam, like a car. For those unfamiliar with the concept, having your headlights on a high beam will increase visibility for the driver at night and in foggy conditions, allowing them to see obstacles earlier than if they were driving with their lights set to low-beam. This can be very beneficial in ensuring safe navigation of the roads.
  12. The alternator indicator light is an important feature in any vehicle. If the light comes on while the engine is running, it can indicate a problem with the alternator. It is best to check the alternator cables and make sure they are properly connected before bringing it into service for further diagnosis and repair if necessary.
  13. It is important to check the air cleaner element periodically and replace or clean it as needed. If not regularly maintained, dust, dirt, and other airborne particles can accumulate in the air cleaner element and reduce its efficiency at removing impurities from circulated air. Regularly replacing or cleaning your air cleaner element will help ensure that you are receiving optimal filtration of pollutants from inside your home or office environment.
  14. It is important to note that if the transmission oil filter light comes on, it could mean that the filter is clogged or the oil temperature is too low. If this occurs, it should be brought in for service immediately as further damage may occur to the vehicle if not properly serviced.
  15. PowrQuad Plus, AutoQuad II and AutoPowr transmissions are equipped with a warning light that indicates when service is required. This light can only be found on these specific models of transmission and it serves to alert the user that maintenance or servicing may be necessary. It is important to pay close attention to this warning light in order to ensure the proper performance of the transmission system.
  16. The turn-signal or hazard warning lights are an important component of any vehicle, as they can be used to alert other drivers when a sudden lane change is required. If these lights remain on for too long, it could lead to unnecessary traffic delays and possible collisions. Drivers should ensure that their turn-signals are turned off after making a lane change and that the hazard warning lights are only activated in emergency situations. It is recommended that drivers check their side mirrors frequently while driving to make sure that the signals have been properly disengaged.
  17. The hazard warning lights on the trailer are activated. This is a necessary safety feature for alerting other drivers of potential danger. It’s important to ensure that these lights remain in working order, as malfunctioning or non-functional turn signals can lead to serious accidents and undesirable outcomes. The responsible driver should always make sure that the turn signal and hazard lights are functioning properly before heading out on their journey.
