Use unleaded gasoline with a minimum octane rating of 87. Avoid ethanol-blended fuels above E10 to prevent engine damage.
Check the battery charge and connections, ensure fuel is reaching the engine, and inspect the spark plugs. If the problem persists, consult the manual or a professional technician.
The recommended tire pressure is typically around 10-14 PSI for the rear tires and 12-15 PSI for the front tires. Refer to the manual for exact specifications.

Remove the air filter cover, take out the filter, and clean it using compressed air or soap and water if it's a washable type. Ensure it's dry before reinstalling.
Excessive vibration can be caused by unbalanced blades, loose components, or worn-out belts. Inspect these parts and replace or tighten as needed.
To winterize, clean the tractor, change the oil, stabilize the fuel, remove the battery, and store the tractor in a dry place. Cover it to protect from dust and moisture.
