Transmission Oil
IMPORTANT: Avoid damage! Do not mix transmission oils. Use John Deere Low Viscosity HY-GARD® (J20D) transmission oil to reduce transmission noise. |
These machines 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.
John Deere Low Viscosity HY-GARD® (J20D) transmission oil is specially formulated to provide maximum protection against mechanical wear, corrosion, and foaming. It may be used in all operating temperatures.
Checking Transmission Oil Level
1. Park machine safely on a level surface. (See Parking Safely in the SAFETY section.)
IMPORTANT: Avoid damage! Hot hydraulic oil will expand and show incorrect oil level. Check level in reservoir when engine is off and oil is cold. |
3. Locate transmission oil reservoir at rear of machine. Reservoir is marked FULL (A) and ADD (B).
IMPORTANT: Avoid damage! Contamination can damage the hydraulic system. Clean thoroughly around reservoir fill cap before opening. |
4. If oil level is low, slide operator's seat ahead and tip it forward to access reservoir (C). Clean area around reservoir cap.
6. Add HY-GARD® (J20D) oil until oil level is at FULL mark on reservoir.
8. Lower and adjust operator's seat.
10. Operate machine forward and in reverse several times.
11. Park machine safely on a level surface. (See Parking Safely in the SAFETY section.)
12. Wait at least 3 minutes for hydraulic oil to cool.
13. Check oil level again. Add oil if necessary.
Changing Transmission Oil
1. Park machine safely on a level surface. (See Parking Safely in the SAFETY section.)
NOTE: Transmission is divided into two internally connected cavities. Rear drain plug (A) will drain differential gear side and front plug (B) will drain hydrostatic side.
3. Place drain pan under drain plugs (A) and (B). Remove plugs.
IMPORTANT: Avoid damage! Contamination can damage the hydraulic system. Clean thoroughly around fill caps before opening. |
4. Clean area around transmission fill cap (C) and cap on transmission oil reservoir (D).
5. Remove fill caps and reservoir filter to improve drainage. Allow to drain completely.
6. Install and tighten transmission drain plugs to 15 N·m (133 lb-in.).
7. Add approximately 2 L (2 qt) John Deere Low Viscosity HY-GARD® (J20D) to transmission fill opening (C) until oil level is at bottom of threads. Install and tighten fill cap.
8. Add approximately 2.4 L (2.5 qt) John Deere Low Viscosity HY-GARD® (J20D) to transmission reservoir (D) until oil level is at FULL mark. Install reservoir filter and cap.
10. Check for leaks around drain plugs and hydraulic filter.
11. Operate machine forward and in reverse several times.
12. Park machine safely on level surface. (See Parking Safely in the SAFETY section.)
13. Wait at least 3 minutes for hydraulic oil to cool.
14. Check oil level in reservoir. Add oil to reservoir if necessary.
Adjusting Cruise Control Lever
NOTE: The cruise control lever is held in position by an adjustable friction mechanism pre-set at the factory. The amount of friction can be adjusted for the operator's preference or to accommodate normal wear.
1. Park machine safely. (See Parking Safely in the SAFETY section.)
Picture Note: Right wheel shown removed for clarity. Removal of wheel is not required.
2. Locate adjusting bolt (A) at right wheel well.
3. Turn adjusting bolt so cruise control lever moves easily forward and rearward while remaining stationary in any desired position:
