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 commercial attachments

and accessories 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 or other operational instructions provided

by Exmark. 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 attachment

or accessory.

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.
