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

General Conditions

The sole liability of Exmark and Exmark Warranty Company

incidental or consequential loss or damage.

Such damages include but are not limited to:
