Checking Front Axle Oil Level

IMPORTANT: Avoid damage! Allow oil one hour cool down and 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.)

2. Allow machine to cool down and oil to settle 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.

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

4. Wipe dipstick clean with a rag. Insert dipstick into axle hole but do not screw it into the axle case.

5. Remove dipstick. Oil level should be at top 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.

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

Changing the Front Axle Oil

1. Operate machine to warm front axle oil.

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

NOTE: For draining purposes there are approximately 2.13 L (2.25 qt) of oil in the front axle. It may be necessary to remove front wheels for access to vent plugs (A).

3. Remove vent plug (A) from both sides of front axle.

4. Remove drain plug (B) from both sides of front axle. Drain oil into suitable container.

5. Remove differential drain plug (C) from front axle. Drain oil into suitable container.

6. Install and tighten three drain plugs (B and C) after all oil is drained.

7. Remove dipstick located on right side of front axle.

8. Add approximately 2.13 L (2.25 qt) of John Deere API GL-5 Gear Oil or its equivalent through dipstick opening.

IMPORTANT: Avoid damage! Allow oil one hour to settle before checking level. Recheck oil level after several hours of operation.


9. Insert dipstick.Do not screw dipstick into case to check oil level. Pull it out.

10. Oil level should be to the top of mark on the dipstick.

11. If oil level is low, add oil through the dipstick opening.

12. Install and tighten the dipstick.

13. Install both vent plugs.

14. Install front wheels if they were removed.

15. Tighten front wheel bolts to 133 N·m (98 lb-ft).

Transmission and Hydraulic Oil

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

The following John Deere transmission and hydraulic oil is preferred:

· Low Viscosity HY-GARD® (JDM J20D)

The following John Deere oil is also recommended if preferred oil is not available:

· HY-GARD® (JDM J20C)

Other oils may be used if recommended John Deere oils are not available, provided they meet one of the following specifications:

· John Deere Standard JDM J20D

· John Deere Standard JDM J20C

IMPORTANT: Avoid damage! You can mix Low Viscosity HY-GARD® and HY-GARD®.

Do not mix any other oils in this transmission. Do not use engine oil or "Type F" (Red) Automatic Transmission Fluid.

Changing Transmission Oil and Filter

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 cap 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 there is approximately 15 L (4 gal) of oil in this transmission.
