Ensure the tractor is on a flat surface. Insert the key into the ignition and turn it to the 'start' position while ensuring the brake is engaged and the PTO is off.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using E85 fuel.
The oil should be changed every 50 hours of operation or at least once every season.
The recommended tire pressure is 10 psi for the front tires and 12 psi for the rear tires.
Check if the battery is charged, inspect the spark plug for wear, ensure the fuel is fresh, and verify that all safety switches are engaged.
Ensure the PTO switch is in the 'on' position, check the belt for wear or damage, and inspect the PTO clutch for proper operation.
Regular maintenance includes checking and replacing the oil, inspecting the air filter, sharpening the blades, and lubricating moving parts.
Ensure blades are sharp and balanced, mow when grass is dry, and adjust the cutting height to avoid scalping.
Clean the tractor, change the oil, fill the fuel tank, add a fuel stabilizer, remove the battery, and store in a dry place.
Check for unbalanced or damaged blades, inspect the drive belt for wear, and ensure all bolts are tightened properly.
