covered by this warranty.  
Shoes, runners, scraper blades, shear bolts, mower blades,  
mower vanes, trimmer line, headlights, light bulbs are not  
covered by this warranty.  
Any defect which is the result of misuse, alteration, improper  
assembly, improper adjustment, neglect, or accident is not  
covered by this warranty.  
Products which were not purchased in the United States,  
Puerto Rico, or Canada are not covered by this warranty.  
In all other countries, contact place of purchase.  
Returning the product registration card to Gravely will

This warranty is subject to the following limitations:  
The purchaser must transport the product to and from the  
place of warranty repair.  
Warranty service must be performed by an authorized  
Gravely service representative. (To find an authorized

LIMITATION OF REMEDY AND DAMAGES  
DISCLAIMER OF FURTHER WARRANTY  
Gravelys liability under this express warranty, and under any  
implied warranty that may exist, is limited to repair or  
replacement of any defective part. Gravely shall not be liable  
for incidental, special, or consequential damages (including  
lost profits). Some states do not allow the exclusion of  
incidental or consequential damages, so the above limitation  
or exclusion may not apply to you.  
Gravely makes no warranty, express or implied,  
other than what is expressly made in this  
warranty. If the law of your state provides that  
an implied warranty of merchantability, or an  
implied warranty of fitness for particular  
purpose, or any other implied warranty, applies  
to Gravely, then any such implied warranty is  
limited to the duration of this warranty. Some  
states do not allow limitations on how long an  
implied warranty lasts, so the above limitation  
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.
