Gear Case Oil

IMPORTANT: Avoid damage! ONLY use a quality oil in this gear case. DO NOT mix any other oils in this gear case. DO NOT use BIO-HY-GARD® in this gear case.


The following John Deere gear case oil is preferred:

· GL-5 GEAR LUBRICANT®-SAE 80W-90

Other gear case oils may be used if recommended John Deere gear case oil is not available, provided they meet the following specification:

· API Service Classification GL-5.

Checking Front Axle Oil Level

IMPORTANT: Avoid damage! Allow oil one hour to settle before checking level to ensure accurate dipstick reading. Repeat oil level check after several hours of operation.


1. Park machine safely. (See Parking Safely in the SAFETY section.) Allow machine to cool down for at least one hour.

IMPORTANT: Avoid damage! Dirt and debris in oil may cause damage to the transaxle. Clean area around opening before removing dipstick.

2. Loosen and remove dipstick (A) located on right side of front axle.

3. Wipe dipstick clean with a rag. Install and tighten dipstick.

4. Remove dipstick. Oil level should be at fill mark on dipstick. If oil level is low:

a. Add GL-5 Gear Lubricant®-SAE 80W-90 or equivalent through dipstick fill opening until oil level is correct.

b. Install and tighten dipstick.

5. Check front axle oil level again after the first several hours of operation.

Changing Front Axle Oil

10. Install and tighten dipstick.

IMPORTANT: Avoid damage! Allow oil one hour to settle before checking level to ensure accurate dipstick reading. Repeat oil level check after several hours of operation.


11. Check front axle oil level.

Transmission Oil

These tractors are equipped with a internal wet disc brake transmission. Use only Low Viscosity HY-GARD® (J20D) transmission oil. DO NOT use type "F" automatic transmission fluid.

IMPORTANT: Avoid damage! Use John Deere Low Viscosity HY-GARD® (J20D) transmission oil to reduce transmission noise and to increase response time for the hydraulics and power steering.


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

Checking Transmission Oil Level (Gear Models)

NOTE: To obtain an accurate dipstick reading allow oil to settle for one hour before checking level. Check oil level after several hours of operation.

1. Park machine safely. (See Parking Safely in the SAFETY section.) Allow machine to cool down for at least one hour.

IMPORTANT: Avoid damage! Help prevent dirt and other contaminants from entering the transmission. Clean area around dipstick before removing.

Do not overfill transmission. Oil expands during operation and could overflow.



MX9067

2. Remove dipstick (A).

3. Check oil level on dipstick; oil level should be at fill mark on dipstick. If oil level is low:

· Add John Deere Low Viscosity HY-GARD® (JDM J20D) or equivalent through dipstick fill opening until oil level is correct.

4. Install and tighten dipstick.

Checking Transmission Oil Level (Hydrostatic Models)

NOTE: To obtain an accurate dipstick reading allow oil to settle for one hour before checking level. Check oil level after several hours of operation.

1. Park machine safely. (See Parking Safely in the SAFETY section.) Allow machine to cool down for at least one hour.

2. Raise operator seat.

IMPORTANT: Avoid damage! Help prevent dirt and other contaminants from entering the transmission. Clean area around dipstick before removing.

Do not overfill transmission. Oil expands during operation and could overflow.



MX9091

3. Remove dipstick (A).

4. Check oil level on dipstick; oil level should be between high and low levels on dipstick.

5. If oil level is low:


MX9092

· Remove fill cap (B).

· Add John Deere Low Viscosity HY-GARD® (JDM J20D) or equivalent through fill opening until oil level is correct.

6. Install fill cap.

7. Install dipstick.

8. Lower seat.

Changing Transmission Oil, Oil Filter and Suction Screen (Gear Models)

c CAUTION: Avoid injury!

Use caution when filling and draining hydraulic oil. During periods of machine operation the hydraulic oil can get hot. Allow engine and oil to cool before servicing.

IMPORTANT: Avoid damage! Contamination of hydraulic fluid could cause transmission damage or failure. Do not remove dipstick from fill opening unless absolutely necessary.

Severe or unusual conditions may require a more frequent service interval.


1. Run engine a few minutes to warm the transmission oil.

2. Park machine safely. (See Parking Safely in the SAFETY section.)

NOTE: For draining purposes, the gear transmission contains approximately 10.5 L (2.5 gal) of oil.
