What is one of the recommended tasks for mower maintenance?

Checking the air filter is an essential task in mower maintenance because a clean air filter ensures that the engine receives sufficient airflow, which is critical for optimal performance. A clogged or dirty air filter can inhibit engine performance, leading to reduced power and increased fuel consumption. Regularly inspecting and replacing the air filter helps maintain the mower’s efficiency and extends its lifespan. This task is a straightforward way to prevent potential engine issues and contribute to overall mower reliability.

The other options do not align with standard mower maintenance practices. Building new equipment involves fabrication and design, which is unrelated to routine maintenance. Changing the oil only during winter is not advisable; oil should be changed based on usage and manufacturer recommendations, typically more frequently in warmer months when mowers are most active. Relying solely on electric power depends on the type of mower and does not address necessary maintenance tasks essential for all types of equipment.
