Toro 12 HP 57430 Operator's Manual

Ensure the tractor is in neutral, then turn the ignition key to the start position while pressing the brake pedal. Release the key once the engine starts.
Check the battery connections for corrosion, ensure the fuel tank is not empty, and verify the spark plug is functioning. If issues persist, consult the manual or a professional technician.
Change the oil every 50 hours of operation or at least once per season to maintain optimal performance.
Use SAE 30 oil for general use. If operating in colder climates, consider using SAE 5W-30 for easier starting.
Locate the cutting height lever on the side of the tractor and adjust it to the desired height setting. Ensure the lever locks into place.
Check if the blades are dull or damaged and sharpen or replace them as necessary. Also, ensure the blade belt is tight and not worn out.
Clean the battery terminals regularly to prevent corrosion, check the water level if applicable, and keep the battery fully charged, especially during off-season storage.
Ensure the engine cooling fins are clean and free from debris. Check the engine oil level and replace it if it's old or low. Also, ensure the air filter is clean.
Check the tire pressure and ensure it is consistent with the manufacturer's recommendations. Inspect for any misalignment or damage to the tires and adjust or replace them as needed.
Regularly check the engine oil and air filter, sharpen the mower blades, lubricate all moving parts, inspect belts and hoses, and clean the tractor after each use to prolong its lifespan.
