Why is my Toro 74947 Lawn Mower engine losing power?
If your Toro Lawn Mower engine is losing power, it could be due to several reasons. The engine load might be excessive, so try reducing the ground speed. A dirty air cleaner can also cause this, so clean the air-cleaner element. Check the oil level in the crankcase and add oil if it's low. Make sure the cooling fins and air passages above the engine are clear of obstructions. The vent hole in the fuel cap could be plugged, so clean or replace the fuel cap. A dirty fuel filter can also cause power loss, so replace it. For issues like dirt, water, or stale fuel in the fuel system, contact an Authorized Service Dealer.
Why is the malfunction indicator light (MIL) on my Toro 74947 on?
If the malfunction indicator light (MIL) on your Toro Lawn Mower comes on, there could be several reasons. The engine might be too hot, in which case you should turn it off and let it cool. Old gas in the tank can also trigger the light, so try using new gas. Ensure the fuel-shutoff valve is completely open. A dirty air cleaner can cause this issue, so clean or replace it as needed. Also, check the battery charge and replace the battery if necessary. If the problem persists, it could be due to incorrect or dirty fuel filters, loose connections to the sensors, low battery voltage, or a blown fuse. For fuel filters or sensor issues, contact an Authorized Service Dealer. Ensure you are using a good 12-volt battery and replace any blown fuses.
What to do if the oil-temperature light is on and the engine rpm is low on my Toro 74947?
