Ensure the parking brake is engaged, the PTO is disengaged, and the throttle is set to choke. Turn the ignition key to start the engine.
Check the battery connections, ensure there is fuel, and verify that the spark plug is in good condition. Also, make sure the safety switches are properly engaged.
Perform regular maintenance every 50 hours of operation or annually, whichever comes first. This includes checking the oil, air filter, and blades.
Use SAE 30 oil for temperatures above 32°F (0°C) and SAE 5W-30 for temperatures below 32°F (0°C).
First, disconnect the spark plug wire to prevent accidental starting. Raise the deck to its highest position, then use a wrench to remove the blade bolts and replace the blades.
Check for debris lodged in the blades, inspect the blades for damage, and ensure that all nuts and bolts are tightened securely.
Sharpen the blades regularly, mow when the grass is dry, and adjust the cutting height to an appropriate level for the grass type.
Inspect the alternator belt for wear or damage, check the battery connections, and test the alternator output with a multimeter.
Clean the tractor thoroughly, change the oil, remove the battery and store it in a cool, dry place, and add a fuel stabilizer to the fuel tank.
Locate the deck height adjustment lever on the tractor. Move the lever to the desired height position, ensuring it locks in place.
