Ensure the tractor is on a level surface. Sit on the seat, engage the parking brake, and ensure the transmission is in neutral. Turn the ignition key to the 'Start' position until the engine runs, then release the key.
Check if there is fuel in the tank and the battery is charged. Ensure the safety switches are engaged, and inspect the spark plug for wear or damage.
Change the oil every 50 hours of operation or at least once every season, whichever comes first. Always refer to the manual for the recommended oil type and procedure.
Use unleaded gasoline with an octane rating of at least 87. Avoid using gasoline with more than 10% ethanol content.
Check the mower deck for levelness and ensure the blades are sharp and properly installed. Inspect the tire pressure and adjust if necessary.
First, disconnect the spark plug and elevate the mower deck. Use a wrench to remove the blade bolt, replace the blade, and tighten the bolt securely. Reconnect the spark plug once complete.
Keep the battery terminals clean and free of corrosion. Check the electrolyte level if applicable and charge the battery during long periods of inactivity.
Ensure the cooling fins and air intake screens are clean and free of debris. Check the engine oil level and coolant system if applicable.
Clean the tractor thoroughly and add a fuel stabilizer to the tank. Change the oil, remove the battery, and store it in a dry place. Cover the tractor to protect it from dust and moisture.
Inspect the fuel and oil levels, check tire pressure, and ensure the blades are sharp. Confirm the operation of all safety switches and controls.
