for a period of two (2) years commencing on the date of original purchase

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.  
Normal wear parts are warranted to be free from defects in material and
