What to do if John Deer Tractor engine will not start?
If your John Deer Tractor engine won't start, make sure the brake pedal is depressed and the mower is disengaged. Check that the spark plug wire is securely connected and that you're using the correct fuel type. Also, inspect the fuel filter and clean or replace it if it's plugged. Finally, check the safety switch and replace it if it's defective. If these steps don't resolve the issue, refer to the Electrical Troubleshooting Section.
Why does my john deer LA125 engine lose power?
Your John Deer Tractor engine may be losing power due to several reasons: the engine might be overheating, there could be too much oil in the engine, the air cleaner might be dirty, or the spark plug could be faulty. Also, the travel speed might be too fast for the conditions, or you might be using the improper fuel. In order to solve this problem you should check the engine cooling system, check and adjust oil level, clean or replace air cleaner, replace the faulty spark plug, reduce travel speed, and use proper fuel type.
What to do if john deer LA125 engine overheats?
If your John Deer Tractor engine is overheating, check the engine air intake screen and clean it if it's plugged. Also, clean the cooling fins. Ensure the engine oil level is correct, adjusting if it's too low or too high. Avoid operating the engine for extended periods at a slow idle speed.
Why john deer LA125 Tractor starter does not work?
If the starter on your John Deer Tractor isn't working or turning the engine, the brake pedal may not be depressed, or the mower might be engaged. Ensure the brake pedal is depressed and the mower is disengaged. Corroded battery terminals or a discharged battery could also be the cause, so clean the battery terminals and charge the battery. A blown fuse can also prevent the starter from working, so replace the blown fuse. If the fusible link in the starting circuit is blown, consult your authorized dealer.
Why does my John Deer Tractor engine backfires?
Your John Deer Tractor engine might backfire due to a faulty spark plug, so replace it. Also, ensure the operator is seated, as raising off the seat can cause backfiring.
Why john deer LA125 Tractor engine stops on hillsides?
If your John Deer Tractor engine stops or misses when operating on hillsides, it could be because the fuel tank is less than half full, so keep it at least half full. It can also happen if the operator is raising off of the seat, so ensure the operator is seated.
What to do if john deer LA125 Tractor engine vapor locks?
If your John Deer Tractor engine vapor locks, the fuel tank vent may be plugged, so clear it. Dirt in the fuel filter, plugged cooling fins, or a loose hose connection at the fuel filter or fuel pump can also cause this issue. Clean or replace the fuel filter, clean the cooling fins, and tighten loose hose connections.
Why does john deer LA125 Tractor engine knock?
A knocking sound in your John Deer Tractor engine can be due to stale or low octane fuel, in which case you should use fresh, high-octane fuel. It could also be caused by an overloaded engine, so reduce the engine load. Low engine speed or a low oil level can also cause knocking, so increase the engine speed and check and adjust the oil level.
Why john deer LA125 battery will not charge?
If your John Deer Tractor battery won't charge, it could be due to a dead cell in the battery, in which case you should replace the battery. Dirty battery cables and terminals can also prevent charging, so clean them. Low engine speed or excessive idling can also affect battery charging, so increase the engine speed.
