Ensure the parking brake is engaged and the transmission is in neutral. Turn the key to the 'Start' position and release it once the engine starts.
Use SAE 30W oil above 40°F (4°C) and SAE 10W-30 below 40°F (4°C) for optimal engine performance.
Change the oil every 50 hours of use or annually, whichever comes first.
Check the fuel level, ensure the battery is charged, inspect the spark plug, and verify that the air filter is clean.
Ensure the engine cooling fins are clean, check the oil level, and make sure the air intake is not blocked.
Keep the battery terminals clean and tight. Store the battery in a cool, dry place during the off-season and charge it regularly.
Disconnect the spark plug wire for safety. Use a wrench to remove the blade bolts, replace with new blades, and tighten securely.
Check the operator's manual, but generally, maintain front tires at 14 psi and rear tires at 10 psi.
Regular maintenance such as air filter replacement, spark plug inspection, and proper tire inflation can improve fuel efficiency.
Drain the fuel tank, change the oil, clean the tractor, and store it in a dry place. Disconnect the battery and charge it periodically.
