 FEDERAL and/or CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT 

YOUR WARRANTY RIGHTS AND OBLIGATIONS 

MTD Consumer Group Inc, the United States Environmental Protection Agency (EPA), and for those products certified for sale in the state 
of California, the California Air Resources Board (CARB) are pleased to explain the emission control system (ECS) warranty on your 2017-
2018 small off-road spark-ignited engine and equipment (outdoor equipment). In California, new outdoor equipment must be designed, 
built and equipped to meet the State’s stringent anti-smog standards (in other states, outdoor equipment must be designed, built, and 
equipped to meet the U.S. EPA small off-road spark ignition engine regulations). MTD Consumer Group Inc must warrant the ECS on your 
outdoor equipment for the period of time listed below, provided there has been no abuse, neglect, or improper maintenance of the 
outdoor equipment. 
Your ECS may include parts such as the carburetor, fuel-injection system, ignition system, catalytic converter, fuel tanks, fuel lines, fuel 
caps, valves, canisters, filters, vapor hoses, clamps, connectors, and other associated emission-related components. 
Where a warrantable condition exists, MTD Consumer Group Inc will repair your outdoor equipment at no cost to you including 
diagnosis, parts, and labor. 

MANUFACTURER’S WARRANTY COVERAGE: 

This emission control system is warranted for two years. If any emission-related part on your outdoor equipment is defective, the part 
will be repaired or replaced by MTD Consumer Group Inc. 

OWNER’S WARRANTY RESPONSIBILITIES: 

As the outdoor equipment owner, you are responsible for performance of the required maintenance listed in your owner’s manual. MTD 
Consumer Group Inc recommends that you retain all receipts covering maintenance on your outdoor equipment, but MTD Consumer 
Group Inc cannot deny warranty solely for the lack of receipts. 
As the outdoor equipment owner, you should however be aware that MTD Consumer Group Inc may deny you warranty coverage if your 
outdoor equipment or a part has failed due to abuse, neglect, improper maintenance, or unapproved modifications. 
You are responsible for presenting your outdoor equipment to MTD Consumer Group Inc’s distribution center or service center as soon 
as the problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have a 
question regarding your warranty coverage, you should contact the MTD Consumer Group Inc Service Department at 1-800-800-7310 or 
at  
http://support.mtdproducts.com. 

GENERAL EMISSIONS WARRANTY COVERAGE: 

MTD Consumer Group Inc warrants to the ultimate purchaser and each subsequent purchaser that the outdoor equipment is: (1) 
designed, built, and equipped so as to conform with all applicable regulations; and (2) free from defects in materials and workmanship 
that cause the failure of a warranted part for a period of two years. 
The warranty period begins on the date the outdoor equipment is delivered to an ultimate purchaser or first placed into service. 
Subject to certain conditions and exclusions as stated below, the warranty on emission-related parts is as follows: 
1. 

Any warranted part that is not scheduled for replacement as required maintenance in the written instructions supplied is 
warranted for the warranty period stated above. If the part fails during the period of warranty coverage, the part will be repaired 
or replaced by MTD Consumer Group Inc according to subsection (4) below. Any such part repaired or replaced under warranty 
will be warranted for the remainder of the period. 

2. 

Any warranted part that is scheduled only for regular inspection in the written instructions supplied is warranted for the warranty 
period stated above. Any such part repaired or replaced under warranty will be warranted for the remaining warranty period. 

3. 

Any warranted part that is scheduled for replacement as required maintenance in the written instructions supplied is warranted 
for the period of time before the first scheduled replacement date for that part. If the part fails before the first scheduled 
replacement, the part will be repaired or replaced by MTD Consumer Group Inc according to subsection (4) below. Any such part 
repaired or replaced under warranty will be warranted for the remainder of the period prior to the first scheduled replacement 
point for the part. 

4. 

Repair or replacement of any warranted part under the warranty provisions herein must be performed at a warranty station at no 
charge to the owner. 

5. 

Notwithstanding the provisions herein, warranty services or repairs will be provided at all of our distribution centers that are 
franchised to service the subject engines or equipment. 

6. 

The outdoor equipment owner will not be charged for diagnostic labor that is directly associated with diagnosis of a defective, 
emission-related warranted part, provided that such diagnostic work is performed at a warranty station. 

7. 

MTD Consumer Group Inc is liable for damages to other engine or equipment components proximately caused by a failure under 
warranty of any warranted part.
