How to Tune Up Your Lawn Mower in 3 Easy Steps

1. Owner's Manual:
   This is your best friend when understanding your specific mower's maintenance requirements.
2. Safety Gear:
   Gloves, safety glasses, and appropriate footwear are essential for protecting yourself.
3. Wrenches and Screwdrivers:
   You'll need these for removing and tightening bolts and screws.
4. Air Filter:
   If your air filter is old and dirty, consider replacing it.
5. Spark Plug:
   A new spark plug can significantly improve your mower's performance.
6. Oil:
   High-quality motor oil suitable for your mower's engine.
7. Fuel Stabilizer:
   To keep your fuel fresh during inactivity.

1. Air Filter:
   Start by removing the air filter cover. Check the condition of the air filter – if it's dirty or clogged, it's time for a replacement. A clean air filter improves air intake and enhances engine performance.
2. Spark Plug:
   Locate the spark plug and use a socket to carefully remove the old plug. Check the electrode for wear and the gap between the electrodes. Consult your owner's manual for the correct gap measurement. If the plug is worn or fouled, replace it with a new one. Installing a new spark plug can lead to easier starts and better fuel efficiency.
3. Oil Change:
   Changing the oil is crucial for maintaining a healthy engine. First, disconnect the spark plug wire for safety. Then locate the oil drain plug and position an oil pan beneath it. Remove the plug and allow the old oil to drain completely. Replace the plug and refill the engine with the appropriate type and amount of oil specified in the manual. Don't forget to check the oil level using the dipstick.

1. Clean the Deck:
   A clean mower deck helps prevent grass clippings from building up and causing rust. Use a wire brush or scraper to remove debris, and consider spraying the deck with a silicone-based lubricant to discourage further buildup.
2. Sharpen the Blade:
   A sharp blade cuts grass cleanly and reduces strain on the engine. Remove the blade by disconnecting the spark plug wire, then use a wrench to loosen the blade bolt. Sharpen the blade with a file or grinder, maintaining the original angle. Reattach the blade securely.
3. Inspect Belts and Cables:
   Check belts and cables for signs of wear or damage. Replace any worn or damaged components to ensure proper operation.
4. Check and Stabilize Fuel:
   If your mower won't be used for an extended period, add a fuel stabilizer to the tank and run the engine for a few minutes to circulate the treated fuel through the system. This prevents fuel from deteriorating and causing starting issues down the line.
