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.
