  • Fuel Issues: This is the most frequent culprit.
    • Old Fuel: Gasoline degrades over time. Drain the old fuel and replace it with fresh fuel. Consider adding a fuel stabilizer.

    • Loose Connection: Ensure the spark plug wire is securely connected.
  • Air Filter: A clogged air filter restricts airflow to the engine.

  • Battery Problems: While the engine turns over, the battery may not be providing enough power.
    • Weak Battery: Check the battery voltage with a multimeter. If it's low, charge the battery or replace it.
    • Corroded Terminals: Clean the battery terminals with a wire brush to ensure a good connection.
  • Safety Switch Issues: Most riding mowers have safety switches that prevent starting if the operator isn't in the seat or the blades are engaged.
    • Faulty Switch: Check the safety switches to ensure they're functioning correctly. A faulty switch may need replacement.

Step-by-Step Troubleshooting

  1. Check the Fuel: Start by ensuring you have fresh fuel in the tank.
