The Toro General Commercial Products Warranty

A Two-Year Limited Warranty

Conditions and Products Covered

The Toro Company and its affiliate, Toro Warranty Company,
pursuant to an agreement between them, jointly warrant your Toro
Commercial Product (“Product”) to be free from defects in
materials or workmanship for two years or 1500 operational
hours*, whichever occurs first. Where a warrantable condition
exists, we will repair the Product at no cost to you including
diagnosis, labor, parts, and transportation. This warranty begins
on the date the Product is delivered to the original retail purchaser.

* Product equipped with hour meter

Instructions for Obtaining Warranty Service

You are responsible for notifying the Commercial Products
Distributor or Authorized Commercial Products Dealer from whom
you purchased the Product as soon as you believe a warrantable
condition exists.

If you need help locating a Commercial Products Distributor or
Authorized Dealer, or if you have questions regarding your
warranty rights or responsibilities, you may contact us at:

Toro Commercial Products Service Department
Toro Warranty Company
8111 Lyndale Avenue South
Bloomington, MN 55420-1196
952-888-8801 or 800-982-2740
E-mail: [e-mail]

Owner Responsibilities

As the Product owner, you are responsible for required mainte­nance and adjustments stated in your operator’s manual. Failure
to perform required maintenance and adjustments can be grounds
for disallowing a warranty claim.

Items and Conditions Not Covered

Not all product failures or malfunctions that occur during the
warranty period are defects in materials or workmanship. This
express warranty does not cover the following:

• Product failures which result from the use of non-Toro
replacement parts, or from installation and use of add-on,
modified, or unapproved accessories

• Product failures which result from failure to perform required
maintenance and/or adjustments

• Product failures which result from operating the Product in an
abusive, negligent or reckless manner

• Parts subject to consumption through use unless found to be
defective. Examples of parts which are consumed, or used up,
during normal Product operation include, but are not limited to,
blades, reels, bedknives, tines, spark plugs, castor wheels,
tires, filters, belts, and certain sprayer components such as
diaphragms, nozzles, and check valves, etc.

• Failures caused by outside influence. Items considered to be
outside influence include, but are not limited to, weather,
storage practices, contamination, use of unapproved coolants,
lubricants, additives, or chemicals, etc.

• Normal “wear and tear” items. Normal “wear and tear” includes,
but is not limited to, damage to seats due to wear or abrasion,
worn painted surfaces, scratched decals or windows, etc.

Parts

Parts scheduled for replacement as required maintenance are
warranted for the period of time up to the scheduled replacement
time for that part.

Parts replaced under this warranty become the property of Toro.
Toro will make the final decision whether to repair any existing part
or assembly or replace it. Toro may use factory remanufactured
parts rather than new parts for some warranty repairs.

General Conditions

Repair by an Authorized Toro Distributor or Dealer is your sole
remedy under this warranty.

Neither The Toro Company nor Toro Warranty Company is
liable for indirect, incidental or consequential damages in
connection with the use of the Toro Products covered by this
warranty, including any cost or expense of providing substi­tute equipment or service during reasonable periods of
malfunction or non-use pending completion of repairs under
this warranty. Except for the Emissions warranty referenced
below, if applicable, there is no other express warranty. All
implied warranties of merchantability and fitness for use are
limited to the duration of this 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.

Note regarding engine warranty: The Emissions Control System
on your Product may be covered by a separate warranty meeting
requirements established by the U.S. Environmental Protection
Agency (EPA) and/or the California Air Resources Board (CARB).
The hour limitations set forth above do not apply to the Emissions
Control System Warranty. Refer to the Engine Emission Control
Warranty Statement printed in your operator’s manual or con­tained in the engine manufacturer’s documentation for details.

Countries Other than the United States or Canada

Customers who have purchased Toro products exported from the United States or Canada should contact their Toro Distributor (Dealer)
to obtain guarantee policies for your country, province, or state. If for any reason you are dissatisfied with your Distributor’s service or
have difficulty obtaining guarantee information, contact the Toro importer. If all other remedies fail, you may contact us at Toro Warranty
Company.
