Why won't the lawn mower start?

If your lawn mower won't start, it could be for a few reasons:

1. Lack of fuel, you should add gasoline at this time.

2. The spark plug wire may have become detached and you should reconnect the spark plug wire.

3. The throttle is not in the starting position. At this time, you need to adjust the throttle to the maximum position.

4. The oil line may be clogged, and you should clean the oil line.

5. The ignition time may be misaligned. In this case, the ignition time should be adjusted to ensure correctness.

6. The spark plug may be damaged and should be replaced with a new one.

7. If poor quality or deteriorated gasoline is used, it should be replaced with gasoline of a suitable brand.

The air filter may be clogged. It is recommended to clean or replace it regularly, make sure to use gasoline of qualified quality, and adjust the spark plug gap and engine status.

9. Lawn mower blades may become dull due to long-term use. It is usually recommended to sharpen the blades every ten days of use, while hob blades can be sharpened every three months.
10. If the lawn mower shakes or vibrates violently during operation, grind the blade to the level of the left and right sides, and be careful to avoid hard objects when using it.

11. When the brush cutter feels weak while working and cannot effectively cut the grass, it may be a problem with the clutch disc, which should be replaced.

12. If smoke comes from your lawn mower's muffler, first try cleaning or replacing the air filter. If the problem persists, the carburetor needs to be adjusted, usually just draining the excess oil and running it for ten minutes. If the problem is not resolved, seek help from professional maintenance personnel.

13. If the pull cord rebounds when starting the lawn mower, it may be that the ignition time was too early, or the blade hit a hard object during the mowing process, damaging the flywheel key.

14. Regarding oil supply, two-stroke lawn mowers use mixed oil (95% gasoline and 5% engine oil), while four-stroke lawn mowers use pure gasoline, and the oil needs to be checked and replenished regularly.

15. To extend the life of the lawn mower, it is recommended to take a 10-minute break every two hours of operation.

Finally, to reduce breakdowns and extend the life of your lawn mower, it is crucial to choose a high-quality lawn mower and follow operating and maintenance guidelines.
