Owner’s Responsibilities
If your product requires warranty service it must be returned to an
authorized Exmark service dealer within the warranty period. This
warranty extends only to turf equipment operated under normal
conditions. You must read the operator’s manual. You must also properly
service and maintain your Exmark product as described in the operator’s
manual. Such routine maintenance, whether performed by a dealer or by
you, is at your expense.
General Conditions
The sole liability of Exmark and Exmark Warranty Company with respect
to this warranty shall be repair or replacement of defective components as
set forth herein. Neither Exmark nor Exmark Warranty Company
shall be liable for any incidental or consequential loss or damage.
Such damages include but are not limited to:
• Expenses related to gasoline, oil or lubricants.
• Travel time, overtime, after hours time or other extraordinary repair
charges or charges relating to repairs or replacements outside of
normal business hours at the place of business of the authorized
Exmark Service Dealer.
• Rental of like or similar replacement equipment during the period of
any warranty, repair or replacement work.
• Any telephone or telegram charges or travel charges.
• Loss or damage to person or property other than that covered by the
terms of this warranty.
• Any claims for lost revenue, lost profit or additional cost as
a result of a claim of breach of warranty.
• Attorney's fees.
No Claim of breach of warranty shall be cause for cancellation or
rescission of the contract of sale of any Exmark mower.
All implied warranties of merchantability (that the product is fit for
ordinary use) and fitness for use (that the product is fit for a
particular purpose) are limited to the duration of the express
warranty.
Some states do not allow exclusions of incidental or consequential
damages, or limitations on how long an implied warranty lasts, so the
above exclusions and limitations 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.
