Service Transmission

These tractors are equipped with a hydraulic wet disc clutch transmission. To avoid chatter, use only Low Viscosity HY-GARD® (J20D) transmission oil. DO NOT use type "F" automatic transmission fluid.


IMPORTANT: Avoid damage! When operating in temperatures below -7°C (20°F), you must use Low Viscosity HY-GARD® or transmission damage will occur.

John Deere Low Viscosity HY-GARD® (J20D) transmission oil is specially formulated to minimize clutch chatter, and to provide maximum protection against mechanical wear, corrosion, and foaming.
