Engine Warranty Maintenance Statement

Maintenance, repair, or replacement of the emission control devices and systems on this engine, which are being done at the customers expense, may be performed by any non-road engine repair establishment or individual. Warranty repairs must be performed by an authorized John Deere dealer.

Avoid Fumes

c CAUTION: Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause serious illness or death.

Move the vehicle to an outside area before running the engine.

Do not run an engine in an enclosed area without adequate ventilation.

· Connect a pipe extension to the engine exhaust pipe to direct the exhaust fumes out of the area.

· Allow fresh outside air into the work area to clear the exhaust fumes out.

Engine Oil

Use oil viscosity based on the expected air temperature range during the period between oil changes.

The following John Deere oils are preferred:


· PLUS-50®

· TORQ-GARD SUPREME®

Other oils may be used if above John Deere oils are not available, provided they meet the following specification:

· API Service Classification SG or higher

Checking Engine Speeds

Check engine speeds when engine is warmed up and not under load.

Observe tachometer.

· Slow idle (no load) - 950 rpm

· Fast idle (no load) - 2810 rpm

If above engine speeds are not to specifications, see your John Deere dealer.

Recommended Engine Coolant

The following John Deere coolants are preferred:

Check container label before using to be sure it has the appropriate specifications for your machine. Use coolant with conditioner or add conditioner to coolant before using.

If using concentrate, mix approximately 50 percent antifreeze with 50 percent distilled or deionized water before adding to cooling system. This mixture will provide freeze protection to -37 degrees C (-34 degrees F).

Certain geographical areas may require lower temperature protection. See the label on your antifreeze container or consult your John Deere dealer to obtain the latest information and recommendations.
