LIMITED WARRANTY- COMMERCIAL ACCESSORY
Any part of the Scag commercial accessory manufactured by Scag and found, in the reasonable judgment of Scag,
to be defective in material or workmanship, will be repaired or replaced by an Authorized Scag Service Dealer without
charge for parts and labor.
The Scag accessory, including any defective part, must be returned to an Authorized Scag Service Dealer within
the warranty period. The expense of delivering the accessory to the dealer for warranty work and the expense of
returning it back to the owner after repair or replacement will be paid for by the owner. Scag’s responsibility in respect
to claims is limited to making the required repairs or replacements, and no claim of breach of warranty shall be cause
for cancellation or rescission of the contract of sale of any Scag machine. Proof of purchase will be required by the
dealer to substantiate any warranty claim. All warranty work must be performed by an Authorized Scag Service
Dealer.
This warranty is limited to 90 days from the date of original retail purchase for any Scag accessory that is used for
commercial purposes, or any other income-producing purpose including rental use.
This warranty does not cover any accessory that has been subject to misuse, neglect, negligence, or accident, or
that has been operated in any way contrary to the operating instructions as specified in the Operator's Manual. The
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.
Scag Power Equipment reserves the right to change or improve the design of any accessory without assuming any
obligation to modify any accessory previously manufactured.
All other implied warranties are limited in duration to the 90 day warranty period. Accordingly, any such implied
warranties including merchantability, fitness for a particular purpose, or otherwise, are disclaimed in their entirety
after the expiration of the appropriate ninety day warranty period. Scag’s obligation under this warranty is strictly
and exclusively limited to the repair or replacement of defective parts and Scag does not assume or authorize anyone
to assume any other obligation for them. Some states do not allow limitations on how long an implied warranty lasts,
so the above limitation may not apply to you.
Scag assumes no responsibility for incidental, consequential or other damages including, but not limited to, expense
for gasoline, oil, expense of delivering the machine to an Authorized Scag Service Dealer and expense of returning
it back to the owner, mechanic’s travel time, telephone or telegram charges, rental of a like product during the time
warranty repairs are being performed, travel, loss or damage to personal property, loss of revenue, loss of use of
the mower, loss of time, or inconvenience. Some states do not allow the exclusion or limitation of incidental or
consequential damages, so the above limitation or exclusion may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
