Briggs & Stratton 40560x50B Parts Manual

Ensure the tractor is on a flat surface, engage the parking brake, set the throttle to the choke position, and turn the ignition key to start the engine. Once started, adjust the throttle to the desired speed.
Check the oil level before each use, replace the oil every 50 hours of operation, inspect the air filter every 25 hours, and replace it as needed. Also, check the tire pressure and tighten any loose bolts regularly.
If the engine won't start, check the fuel level, ensure the spark plug is clean and properly gapped, verify the air filter is not clogged, and make sure the battery is fully charged.
Use SAE 30 oil above 40°F (4°C) and 10W-30 below 40°F (4°C) for the engine. Always refer to the user manual for specific recommendations based on your operating conditions.
Ensure the engine is off and the spark plug wire is disconnected. Tilt the tractor safely, remove the blade bolt using a wrench, replace the old blade with a new one, and tighten the bolt securely.
Check for any debris lodged in the blades, inspect the blades for damage or imbalance, and ensure all bolts and fasteners are tightened. If the problem persists, consult a professional technician.
Perform regular maintenance such as changing the oil, replacing the air filter, and keeping the blades sharp. Also, operate the tractor at the recommended speed and avoid unnecessary idling.
Clean the tractor thoroughly, change the oil, add fuel stabilizer to the fuel tank, remove the battery, and store it in a cool, dry place. Cover the tractor to protect it from dust and moisture.
Locate the cutting height adjustment lever on the tractor's deck. Adjust the lever to the desired cutting height position, ensuring it is securely locked in place.
Check the transmission fluid level and top it off if necessary. Inspect for any visible leaks or damage to the transmission system. If the issue persists, consult the user manual or a professional technician.
