MANUFACTURER'S LIMITED WARRANTY FOR:
The limited warranty set forth below is given by MTD LLC with
respect to new merchandise purchased and used in the
United States, its possessions and territories.
"MTD"warrants this product against defects in material and
workmanship for a period of two (2) years commencing on the
date of original purchase and will, at its option, repair or
replace, free of charge, any part found to be defective in
materials or workmanship. This limited warranty shall only
apply if this product has been operated and maintained in
accordance with the Operator's Manual furnished with the
product, and has not been subject to misuse, abuse,
commercial use, neglect, accident, improper maintenance,
alteration, vandalism, theft, fire, water, or damage because of
other peril or natural disaster. Damage resulting from the
installation or use of any part, accessory or attachment not
approved by MTD for use with the product(s) covered by this
manual will void your warranty as to any resulting damage.
Normal wear parts or components thereof are subject to
separate terms as follows: All normal wear parts or
component failures will be covered on the product for a period
of 90 days regardless of cause. After 90 days, but within the
two year period, normal wear part failures will be covered
ONLY IF caused by defects in materials or workmanship of
OTHER component parts. Normal wear parts and
components include, but are not limited to: batteries, belts,
blades, blade adapters, grass bags, rider deck wheels, seats,
snow thrower skid shoes, shave plates, auger spiral rubber,
and tires.
HOW TO OBTAIN SERVICE: Warranty service is available,
WITH PROOF OF PURCHASE, through your local authorized
service dealer. To locate the dealer in your area, check your
Yellow Pages, or contact MTD LLC at P.O. Box 361131,
Cleveland, Ohio 44136-0019, or call 1-800-800-7310 or 1-
330-220-4683 or log on to our Web site at
www.mtdproducts.com.
This limited warranty does not provide coverage in the
following cases:
a. The engine or component parts thereof. These items
may carry a separate manufacturer's warranty. Refer
to applicable manufacturer's warranty for terms and
conditions.
b. Log splitter pumps, valves, and cylinders have a
separate one year warranty.
c. Routine maintenance items such as lubricants, filters,
blade sharpening, tune-ups, brake adjustments, clutch
adjustments, deck adjustments, and normal
deterioration of the exterior finish due to use or
exposure.
IMPORTANT: Owner must present Original Proof of Purchase to obtain warranty coverage.
d. MTD does not extend any warranty for products sold or
exported outside of the United States, its possessions
and territories, except those sold through MTD's
authorized channels of export distribution.
e. Replacement parts that are not genuine MTD parts.
f. Service completed by someone other than an
authorized service dealer.
g. Transportation charges and service calls.
No implied warranty, including any implied warranty of
merchantability of fitness for a particular purpose,
applies after the applicable period of express written
warranty above as to the parts as identified. No other
express warranty, whether written or oral, except as
mentioned above, given by any person or entity,
including a dealer or retailer, with respect to any product,
shall bind MTD. During the period of the warranty, the
exclusive remedy is repair or replacement of the product
as set forth above.
The provisions as set forth in this warranty provide the
sole and exclusive remedy arising from the sale. MTD
shall not be liable for incidental or consequential loss or
damage including, without limitation, expenses incurred
for substitute or replacement lawn care services or for
rental expenses to temporarily replace a warranted
product.
Some states do not allow the exclusion or limitation of
incidental or consequential damages, or limitations on how
long an implied warranty lasts, so the above exclusions or
limitations may not apply to you.
In no event shall recovery of any kind be greater than the
amount of the purchase price of the product sold. Alteration
of safety features of the product shall void this warranty.
You assume the risk and liability for loss, damage, or injury to
you and your property and/or to others and their property
arising out of the misuse or inability to use the product.
This limited warranty shall not extend to anyone other than the
original purchaser or to the person for whom it was purchased
as a gift.

limited warranty gives you specific legal rights, and you may
also have other rights which vary from state to state.
