Emissions Service Information
A qualied repair shop or person of the owner’s choosing may
maintain, replace, or repair emission control devices and systems with
original or equivalent replacement parts. However, warranty, recall and
all other services paid for by John Deere must be performed at an
authorized John Deere service center.
Within the warranty period, John Deere will reimburse reasonable
service costs incurred at service providers outside the John Deere
authorized network only in an unsafe, emergency condition if an
authorized John Deere dealer is not available and the failure does not
arise from the owner’s misuse or failure to perform required
maintenance. An emergency situation exists under this section if, after
30 days, the authorized John Deere network is unable to perform the
repairs or source replacement parts.
Emission Control System Certication Label
NOTE: Tampering with emission controls and components by
unauthorized personnel may result in severe nes or penalties.
Emission controls and components can only be adjusted by EPA
and/or CARB authorized service centers. Contact your John
Deere Retailer concerning emission controls and component
questions.
The presence of an emissions label signies that the engine has been
certied with the United States Environmental Protection Agency
(EPA) and/or California Air Resources Board (CARB).
The emissions warranty applies only to those engines marketed by
John Deere that have been certied by the EPA and/or CARB; and
used in the United States and Canada in o-road mobile equipment.
Altitude Adjustment (Gasoline or Propane Converted Engines
Only)
If your engine features a carburetor it is calibrated by the engine
manufacturer and is not adjustable.
If your engine is operated at altitudes below 610 m (2,000 ft.), a high
altitude carburetor jet kit is not required. If your engine is operated at
altitudes above 610 m (2,000 ft.), a high altitude carburetor jet kit may
be required for proper engine performance and emissions control.
Operating the engine with the wrong carburetor conguration at a
given altitude may increase the engine’s emissions and decrease fuel
eciency and performance.
See a qualied service provider for details on jet kit requirements for
your specic product.
