ship for a period of three (3) years commencing on the date of original purchase and will, at its option, repair or replace, free
of charge, any part found to be defective in materials or workmanship. This limited warranty shall only apply if this product
has been operated and maintained in accordance with the Operator’s Manual furnished with the product, and has not been
subject to misuse, abuse, commercial use, neglect, accident, improper maintenance, alteration, vandalism, theft, fire, water,
or damage because of other peril or natural disaster. Damage resulting from the installation or use of any part, accessory
or attachment not approved by MTD for use with the product(s) covered by this manual will void your warranty as to any
resulting damage.
