Ensure the parking brake is engaged, the PTO is disengaged, and the throttle is set to choke. Turn the ignition key to the start position until the engine starts, then release it.
Check the fuel level, battery charge, and ensure the spark plug is functioning. Additionally, inspect for any blown fuses or loose connections.
Change the engine oil after the first 5 hours of use, and then every 50 hours or annually, whichever comes first.
Use SAE 30 oil for temperatures above 40°F (4°C) and 10W-30 for temperatures below 40°F (4°C).
Check the tire pressure, ensure the mower deck is level, and inspect the blades for dullness or damage. Adjust as necessary.
Remove the air filter cover, take out the filter, and clean it with mild detergent and water. Allow it to dry completely before reinstalling.
Use the height adjustment lever located on the side of the tractor to set the desired mowing height. Ensure both sides are set equally.
Clean the tractor thoroughly, change the oil, add fuel stabilizer, and disconnect the battery. Store in a dry, covered location.
Disconnect the spark plug wire, use a spark plug socket to remove the old plug, and install a new one by hand before tightening with the socket.
Check the oil level, air filter, fuel filter, tire pressure, and blades. Inspect belts for wear and ensure all nuts and bolts are tight.
