Whether or not you believe a clogged air filter is your lawn mower’s problem, take a few minutes to check and perform proper maintenance on your air filter.  If your lawn mower has a multi-stage air filter, be sure to clean or replace both stages.  The benefits of fuel economy and better performance can be amazing.

Dried out grass, dirt, and leaf dust all put tremendous particulate matter into the air. As your lawn mower operates, it sucks that same dust laden air through the airfilter and into the carburetor. After weeks of mowing in dusty conditions, your air filter is probably clogged with the dust and dirt of a thousand lawns.
