Owner’s Responsibilities

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

Such damages include but are not limited to:

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.
