Ensure the tractor is in neutral. Engage the parking brake, set the throttle to 'fast', and turn the ignition key to start the engine.
Use SAE 30 oil for temperatures above 40°F and SAE 5W-30 for temperatures below. Ensure the oil is API classified SJ or higher.
Sharpen the blades at least once a season or after every 25 hours of use to maintain optimal performance.
Check the battery charge, fuel quality, and spark plug condition. Replace or charge the battery and clean or replace the spark plug if 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.
Stop the engine and allow it to cool. Check the coolant levels and ensure the radiator fins are clean and unobstructed.
Disconnect the spark plug, remove the mower deck, and loosen the belt guides. Replace the old belt with a new one, following the belt routing diagram.
Regularly sharpen blades, maintain proper tire pressure, and adjust the mower deck to the correct height for your grass type.
Clean the tractor thoroughly, change the oil, stabilize the fuel, charge the battery, and store in a dry place.
Use the height adjustment lever located near the driver's seat to raise or lower the mower deck to the desired height.
