Common Reasons Your Lawn Mower Won’t Start
When your lawn mower won’t start, several common reasons might be the culprit. Understanding these issues helps you troubleshoot and get your mower running smoothly again.
Fuel Issues
Fuel problems often prevent your lawn mower from starting. Check the fuel tank first to ensure it’s filled with fresh gasoline. Old fuel can degrade and lead to clogs in the fuel system. If the mower hasn’t been used for months, consider draining the old fuel and replacing it with new. Look for visible debris in the fuel filter or carburetor as well; clogs here can also stop fuel from reaching the engine.
Battery Problems
Battery issues result in a mower that won’t crank. Ensure the battery connections are tight and free of corrosion. If you notice corrosion, clean the terminals with a wire brush. Testing the battery voltage can help identify issues. If the voltage is low, charge the battery fully or replace it if it’s unable to hold a charge.
Starter Motor Malfunctions
Starter motor malfunctions can prevent the engine from turning over. Listen for clicking sounds when you turn the ignition; this typically indicates a weak electrical connection. Check the wiring connected to the starter for any signs of damage. If everything looks intact, the starter motor itself might be faulty and require replacement.
Step-by-Step Troubleshooting Guide
Follow these steps to identify and solve common issues with your lawn mower.
Check the Fuel Supply
Check the fuel level in your tank. Look for fresh gasoline, as old fuel can cause starting problems. If your fuel’s been sitting for over 30 days, replace it. Make sure the fuel line is not clogged or damaged. Check for leaks as well. Empty any remaining fuel and refill with a ethanol-free gasoline for optimal performance.
Inspect the Battery and Cables
Inspect your battery first. Look for a secure connection; loose cables prevent the mower from starting. Remove any corrosion with a battery cleaner or a mixture of baking soda and water. Ensure your battery is charged. A dead battery can cause the starter motor to malfunction. Replace the battery if it’s over three years old or shows signs of damage.
Examine the Spark Plug
Examine the spark plug. Remove it carefully and check for dirt or wear. Clean or replace it as needed. A dirty or faulty spark plug won’t ignite the fuel, leading to starting issues. Ensure the gap in the spark plug is set correctly, typically around 0.030 inches. Reinstall it, making sure it’s snug but not overly tight.
Maintenance Tips for Smooth Operation
Keeping your lawn mower in top condition ensures it starts easily and runs efficiently. Implement these maintenance tips to enhance its performance.
Regular Cleaning and Servicing
Clean the mower after each use. Remove grass clippings and debris from the deck, blades, and other parts. Use a brush or compressed air to dislodge stuck material. Check the oil level regularly, and change it if it appears dark or gritty. Replace the air filter as needed to maintain airflow. Regular servicing keeps the engine running smoothly.
Seasonal Checkups
Perform a thorough inspection at the beginning of each season. Examine the spark plugs for wear and replace them if necessary. Check the fuel system for leaks and ensure fresh gasoline is available. Inspect belts and cables for fraying or damage. Seasonal checkups help prevent issues before they arise, keeping your mower ready for action.
Proper Storage Techniques
Store your lawn mower in a dry, sheltered location. Protect it from moisture and extreme temperatures to prevent rust and corrosion. Before storing, drain the fuel or add a fuel stabilizer. This action prevents fuel degradation. Cover the mower with a tarp or specialized cover to shield it from dust and debris. Proper storage extends the life of your mower and ensures it starts easily when you need it.
