However, if a component fails due to a manufacturing defect within the warranty period, it is likely covered. Regular maintenance, as outlined in this manual, is essential to keep your warranty valid. Neglecting scheduled maintenance, such as oil changes or air filter replacements, can void your warranty if the resulting damage is determined to be a direct consequence of this neglect. Always keep detailed records of all maintenance performed on your tractor. These records serve as proof that you have adhered to the recommended maintenance schedule, which can be invaluable when making a warranty claim.
