Air filter, as the name suggests, filters the air that enters the lawn mower engine. Replacing air filter is one of the easiest albeit very important practice in maintaining normal operation of your lawn mower and lawn mower parts. During operation, the different engine parts move at rapid pace causing high friction. Dirts, when they get into the engine and get mixed up with fuel or oil cause considerable wear to all the engine moving parts. Air filter prevents abrasive particulate matter from entering the engine’s cylinders, where it would cause mechanical wear and oil contamination.
