Drain the Gas or Add Stabilizer<\/strong><\/h3>    <p>Unruh emphasizes that &#8220;draining fuel in wintertime is important&#8221; for gas mowers. Run the mower until the tank empties, or add fuel stabilizer if you prefer leaving gas in the tank.<\/p>    <p>&#8220;Allowing ethanol or untreated fuel to remain in the tank for months can cause issues when starting the lawn mower,&#8221; warns Garner.<\/p>    <p>For a detailed guide, see: <a href=\"https:\/\/www.lawnstarter.com\/blog\/lawn-care-2\/how-to-drain-gas-from-lawn-mower\/\">How to Drain Gas From a Lawn Mower<\/a><\/p>    <p><strong>Pro Tip<\/strong>: If using a fuel stabilizer, check the label to see how long it keeps fuel fresh.

Low or dirty fluid causes sluggish operation and transmission damage.<\/li>    <li><strong>Level the mower deck:<\/strong> An unlevel deck creates uneven cuts and scalping. Check deck level at the start of each season by measuring blade height at multiple points. Adjust deck hangers or chains per your manual&#8217;s instructions.<\/li>    <li><strong>Grease spindle bearings:<\/strong> Apply grease to deck spindle bearings every 25 hours or monthly during heavy use. Dry bearings cause excessive wear and eventually lead to spindle failure.<\/li>    <li><strong>Inspect deck belt:<\/strong> Check the deck engagement belt for cracks, fraying, or glazing.
