What is one sign that a lawn mower requires maintenance?

Uneven cutting or difficulty starting is a clear indicator that a lawn mower requires maintenance. When a mower isn’t cutting evenly, it could be a sign that the blades are dull, damaged, or need adjusting. Additionally, if the mower has trouble starting, it might indicate that there's an issue with the engine, fuel system, or spark plugs. Regular maintenance, such as sharpening blades, changing spark plugs, and ensuring proper fuel levels, can prevent these issues and ensure that the mower operates efficiently. Identifying these signs early can help extend the lifespan of the equipment and improve overall performance.
