warranty does not apply to any damage to the accessory that is the result of improper maintenance, or to any
accessory or parts that have not been assembled or installed as specified in the Operator's Manual.
The warranty does not cover any accessory that has been altered or modified. In addition, the warranty does not
extend to repairs made necessary by normal wear, or by the use of parts or accessories which, in the reasonable
judgment of Scag, are either incompatible with the Scag mower or adversely affect its operation, performance or
durability. This warranty does not cover engines and electric starters, which are warranted separately by their
manufacturer.
