Briggs & Stratton 405007x18B Parts Manual

Ensure that the tractor is on a flat surface. Engage the parking brake, set the throttle to the 'fast' position, and turn the ignition key to start the engine.
Check the fuel level, ensure the spark plug is connected, and verify that the battery is charged. If the problem persists, consult the user manual for further troubleshooting steps.
It is recommended to change the oil after the first 5 hours of use and then every 50 hours of operation or at least once per season.
Use SAE 30 oil for temperatures above 40°F (4°C) and SAE 10W-30 for temperatures below 40°F (4°C).
First, ensure the transmission is engaged and the drive belt is not loose or damaged. Check for any obstructions and make sure the parking brake is fully released.
The recommended tire pressure is typically 10 PSI for the rear tires and 14 PSI for the front tires. Always refer to the user manual for exact specifications.
Regularly check the blades for sharpness, damage, or wear. Sharpen or replace blades as needed, and ensure they are properly balanced to avoid vibrations.
Check for loose bolts and nuts, inspect the blades for damage or imbalance, and ensure that the engine mounts are secure.
Remove the air filter cover, take out the filter, and gently tap it to remove loose dirt. If it's extremely dirty, wash it with mild detergent and water, let it dry completely, and then reinstall it.
Check the battery terminals for corrosion and clean them if necessary. Ensure that the battery is fully charged and the fluid levels are adequate.
