Toro General Commercial Products Warranty

A Two-Year Limited Warranty

Conditions and Products Covered

The Toro Company and its affi liate, 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
fi rst. This warranty is applicable to all products with the exception of
Aerators (refer to separate warranty statements for these products).
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 800-952-2740
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 warranty does
not cover the following:

Product failures which result from the use of non-Toro replace-

•

ment parts, or from installation and use of add-on, or modifi ed
non-Toro branded accessories and products. A separate waranty
may be provided by the manufacturer of these items.
Product failures which result from failure to perform recomended

•

maintenance and/or adjustments. Failure to properly maintain
your Toro product per the Recommended Maintenance listed in
the Operator’s Manual can result in claims for warranty being
denied.
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,
brake pads and linings, clutch linings, blades, reels, rollers and
bearings (sealed or greasable), bed knives, aerator crankshaft
and stomper arm bearings, tines, spark plugs, castor wheels and
bearings, tires, fi lters, belts, and certain sprayer components
such as diaphragms, nozzles, and check valves, etc.

Failures caused by outside infl uence. Conditions considered to be

•

outside infl uence include, but are not limited to, weather, storage
practices, contamination, use of unapproved coolants, lubricants,
additives, fertilizers, water, or chemicals, etc.

•

Normal noise, vibration, wear and tear, and deterioration.

•

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 are covered for the
duration of the original product warranty and become the property of
Toro. Toro will make the fi nal decision whether to repair any existing
part or assembly or replace it. Toro may use remanufactured parts for
warranty repairs.

Note Regarding Deep Cycle Battery Warranty:

Deep cycle batteries have a specifi ed total number of kilowatt-hours
they can deliver during their lifetime. Operating, recharging, and ainte­nance techniques can extend or reduce total battery life. As the batter­ies in this product are consumed, the amount of useful work between
charging intervals will slowly decrease until the battery is completely
worn out. Replacement of worn out batteries, due to normal consump­tion, is the responsibility of the product owner. Battery replacement
may be required during the normal product warranty period at owner’s
expense.

Maintenance is at Owner’s Expense

Engine tune-up, lubrication cleaning and polishing, replacement of
fi lters, coolant, and completing recommended maintenance are some
of the normal services Toro products require that are at the owner’s
expense.

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 connetion
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 fi tness for use are limited to the duration of this express war-
ranty.

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 specifi c 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 supplied with your product 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 dissatisfi ed with your Distributor’s service or have diffi culty ob-
taining guarantee information, contact the Toro importer.
