installation or use of any part, accessory or attachment not 
approved by Troy-Bilt 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,

adjustments, deck adjustments, and normal deterioration 
of the exterior finish due to use or exposure.

d.

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 Troy-Bilt. 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. Troy-Bilt 
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.

HOW STATE LAW RELATES TO THIS WARRANTY: This 
limited warranty gives you specific legal rights, and you may 
also have other rights which vary from state to state.

IMPORTANT:
