Inspect the air filter and clean or replace it as needed. A clogged air filter can restrict airflow to the engine, reducing performance and potentially causing damage. Check all belts and hoses for cracks, fraying, or other signs of wear. Replace any worn or damaged belts and hoses before starting the engine. Reconnect the battery cables, ensuring they are securely fastened. Double-check that all connections are clean and corrosion-free.
Before cranking the engine, turn the ignition key to the "on" position (without starting the engine) for a few seconds to allow the fuel pump to prime the fuel system. This is especially important if the tractor has been stored for an extended period. Once the fuel system is primed, attempt to start the engine. If the engine doesn't start immediately, don't crank it for more than 15-20 seconds at a time. Allow the starter motor to cool down for a few minutes between attempts to prevent overheating. After the engine starts, let it idle for a few minutes to allow the oil to circulate and warm up before putting it under load. Monitor the engine for any unusual noises, leaks, or vibrations. If you notice any problems, shut down the engine and investigate the cause before operating the tractor.
