Why Won't My Mower Crank?

When your mower refuses to crank, it can be frustrating, especially when you have a task at hand. However, there can be several reasons behind this issue. By identifying the cause, you can take appropriate steps to rectify the problem and have your mower up and running smoothly again.

Check the Fuel Level and Quality

One of the primary reasons why a mower fails to crank is inadequate fuel supply or poor fuel quality. Ensure that there is enough fuel in the tank and it is not stale or contaminated. If the fuel seems old, it is recommended to drain it and replace it with fresh fuel.

Inspect the Spark Plug

A faulty or dirty spark plug can also prevent your mower from cranking. Remove the spark plug and inspect it for signs of damage or fouling. If necessary, clean it using a wire brush or replace it with a new one. It is advisable to consult your mower's manual for specific instructions regarding spark plug maintenance.

Check the Battery (For Electric Mowers)

If you have an electric mower and it fails to crank, the battery might be the culprit. Check if the battery is charged sufficiently. If not, connect the mower to a power source using the appropriate charger. If the battery is old or damaged, consider replacing it with a new one.

Inspect the Air Filter

A clogged or dirty air filter can restrict the airflow and prevent the engine from starting. Remove the air filter and clean it thoroughly. If it is excessively dirty or damaged, consider replacing it with a new one.

Ensure the Safety Features Are Engaged Properly

Modern mowers come with safety features such as seat sensors, blade engagement switches, or parking brakes. If these features are not engaged correctly, your mower may not crank. Double-check and ensure all safety features are correctly activated as per the manufacturer's instructions.

Seek Professional Assistance

If you have checked the above factors and your mower still refuses to crank, it might be time to seek professional help. A qualified technician can diagnose the problem accurately and provide appropriate solutions to get your mower working again.

In conclusion, troubleshooting a mower that won't crank requires a systematic approach. Start with simple checks like fuel levels, spark plug, battery (for electric mowers), air filter, and safety features. If the issue persists, it is advisable to consult a professional to avoid further damage. With proper maintenance and timely repairs, you can ensure your mower performs efficiently for years to come.
