workmanship for a period of two (2) 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

apply if this product has been operated and maintained in  
accordance with the Operators Manual furnished with the

of other peril or natural disaster. Damage resulting from the  
installation or use of any accessory or attachment not  
approved by MTD Products Inc. for use with the product(s)  
covered by this manual will void your warranty as to any  
resulting damages.  
No implied warranty, including any implied warranty of

nent failures will be covered on the product for a period of
