Transaxle Oil



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

John Deere HY-GARD™ transmission and hydraulic oil is recommended for most normal operating temperatures.

NOTE: For temperatures below -13? C (0? F) John Deere low viscosity HY-GARD™ may be used. If used at temperatures above -13? C (0? F) some brake squeal may be heard due to lower viscosity of the oil at higher temperatures.

Other oils may be used if they meet John Deere standards JDM J20C and JDM J20D.

Checking Transaxle Oil Level

IMPORTANT: Avoid damage! Hot hydraulic oil will expand and show incorrect oil level. Check oil level:

• When oil is cold.

• With engine not running.


1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)

2. Raise and secure cargo box.

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

3. Remove dipstick (A) located on the top of the transaxle housing. Wipe dipstick clean.

4. Check oil level by setting dipstick on threads in transaxle case, then removing and checking oil level.

5. Add oil as needed through the dipstick fill hole.

6. Install and tighten dipstick.

7. Lower the cargo box.

Changing Transaxle Oil

1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)

2. Raise and secure cargo box.

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

Be sure dipstick is installed before removing drain plug. Slowly remove dipstick after plug is removed to control rate of oil flow draining into drain pan.

Picture Note: TS shown.

3. Position drain pan under transaxle drain plug (A).

4. Remove plug and drain oil.

5. Check washer on drain plug. Replace if missing or in poor condition.

6. Install and tighten drain plug to 30 - 35 N•m (22 - 26 lb-ft).

7. Remove dipstick located on top of transaxle housing. Wipe dipstick clean.

8. Add oil: Start by adding approximately 4.7 L (5.0 qt).

9. Check oil level by setting dipstick on threads in transaxle case, then removing and checking oil level.

10. Wait for two minutes then check oil level. Add oil if necessary.

11. Install dipstick and tighten.

12. Lower the cargo box.

Checking Drive Belt

c CAUTION: Avoid injury! Rotating parts can catch fingers, loose clothing, or long hair. Wait for engine and all moving parts to stop before leaving operator’s station to adjust or service machine.

1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)

2. Raise and secure cargo box.

3. Rotate and inspect belt for wear or damage.


MX32942

Picture Note: TS shown.

4. Measure the top surface of the belt width at (A). Dimension should be a minimum of 27 mm (1.1 in.).

5. Replace belt if worn beyond limit.

6. Lower the cargo box.

Replacing Drive Belt

c CAUTION: Avoid injury! Rotating parts can catch fingers, loose clothing, or long hair. Wait for engine and all moving parts to stop before leaving operator’s station to adjust or service machine.

1. Park the vehicle safely. (See Parking Safely in the SAFETY section.)

2. Raise and secure cargo box.

3. Route the belt over pulley (A) of the driven clutch. Rotating the driven pulley will aid in removing the belt.

4. Route belt over drive pulley (B) to remove.

5. Install new belt by routing over drive pulley and then over the driven clutch pulley.

6. Lower the cargo box.

Checking Drive Chain Tension (TH 6x4)

NOTE: Drive chain is set taught at the factory and will not reach normal stretch limits until vehicle has experienced reasonable hours of operation.

1. Stop vehicle on level surface. Stop engine, but do not lock park brake.

2. Put transmission in neutral and traction assist in off position.

c CAUTION: Avoid injury! The machine can fall or slip from an unsafe lifting device or supports.

• Use a safe lifting device rated for the load to be lifted.

• Lower machine onto jack stands or other stable supports and block wheels before servicing.

3. Use a safe lifting device to raise all four rear wheels off ground. Place jack stands or wooden blocks under vehicle.

4. Raise and secure cargo box.

5. Rotate rear wheels toward each other so that chain sag is at top of chain.

6. Place straight edge across top of sprockets (A) and measure distance (sag) (B) from bottom of straight edge to top of chain. Slack should be 13 to 25 mm (0.5 to 1.0 in.).

7. Adjust chain tension if necessary.

Adjusting Drive Chain Tension (TH 6x4)

c CAUTION: Avoid injury! Rotating parts can catch fingers, loose clothing, or long hair. Wait for engine and all moving parts to stop before leaving operator’s station to adjust or service machine.

1. Park vehicle on a level surface. Stop engine, but do not lock park brake.

2. Put transmission in neutral and traction assist in off position.

c CAUTION: Avoid injury! The machine can fall or slip from an unsafe lifting device or supports.

• Use a safe lifting device rated for the load to be lifted.

• Lower machine onto jack stands or other stable supports and block wheels before servicing.

3. Use a safe lifting device to raise all four rear wheels off ground. Place jack stands or wooden blocks under vehicle.

4. Raise and secure cargo box.

IMPORTANT: Avoid damage! Avoid stripping threads from adjustment bolt (C). Loosen housing nuts (A) before turning adjustment bolts.

5. Loosen four nuts (A) for both axles so axle housings (B) can slide easily forward and rearward.

IMPORTANT: Avoid damage! Do not adjust chain too tightly or it could be damaged.


6. Turn adjustment bolts (C) at both sides to remove chain sag. Make sure chain tension is the same at both sides of vehicle.

7. Tighten axle housing nuts (A) to 90 N•m (70 lb-ft), then back off adjustment bolts (C) one half turn to relieve force on bolt.

8. Check for proper and equal chain tension at both sides of vehicle.

9. Rotate drive wheels approximately 120?. Check again at both sides of vehicle for equal chain tension, making sure no tight spots exist. Repeat two more times.

10. Remove jack stands and lower vehicle to ground.
