Changing Transmission Oil and Hydraulic Suction Oil Filter

CAUTION: Avoid injury! Touching hot surfaces can burn skin. The engine, components, and fluids are hot when engine has been running. Allow the engine to cool before servicing or working near the engine and components.

IMPORTANT: Avoid damage! If there is evidence of severe oil contamination, it may be necessary to change the oil several times.

Contamination of hydraulic fluid could cause transmission damage or failure.

Severe or unusual conditions require a more frequent service interval.

NOTE: Transmission oil can be changed every 1200 hours or 3 years if the following requirements are met:

• Use John Deere Hy-Gard™ or Lo-Vis Hy-Gard oil.
• Suction and transmission filter are both changed every 400 hours.
• Perform oil-scan of transmission oil every 400 hours or once per year.
