Hydraulics and Hydraulic Oil

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


KV0733

A sufficient quality and quantity of hydraulic oil is essential for full lift cylinder action, drive/steering action, and protection against severe damage to hydrostatic pumps, charge pump, control valve, and hydraulic pump motors.

The following hydrostatic oils are preferred:

John Deere HY-GARD.

John Deere low viscosity HY-GARD (cold weather operation only).

Checking Hydraulic Reservoir Oil Level

IMPORTANT: Avoid damage! To ensure an accurate reading, check level only when the hydraulic oil is cold and the boom is down with the boom and bucket cylinders fully retracted

When checking or filling the reservoir, be careful not to get dirt into reservoir or oil.

Do not overfill the hydraulic oil reservoir. If overfilled, oil can be blown out of the dipstick tube into the engine area.


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

2. Open engine cover and remove left side panel.


CWP105a

3. Remove dipstick (A).

NOTE: Add less than one quart if oil level measures to mark at (C).


KV14284

4. Oil should be at maximum mark (B).

5. Add oil if necessary:

Clean any dirt and debris from area around dipstick tube.

Remove dipstick and, using a clean funnel, fill reservoir with John Deere HY-GARD or low viscosity HY-GARD oil.

Install dipstick.

6. Install side panel and close engine cover and rear service door.

Changing Hydraulic Oil Filter

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

2. Raise ROPS and assure ROPS is safely in the locked position.


KV15241

3. Turn filter (A) counterclockwise with a filter wrench to remove it.

4. Put a film of clean hydraulic oil on seal of new filter.

5. Install the filter until it contacts the mounting surface. Tighten filter by hand 2/3 to 1 turn more.

6. Lower ROPS.

Changing Hydraulic Oil

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

2. Open engine cover and remove left side panel.

3. Remove hydraulic oil dipstick.

4. Remove skid plate.


KV13964

Picture Note: Bottom view

5. Install a suitable container under hydraulic reservoir drain plugs (A).

NOTE: Rear plug only shown in photo. Remove both forward and rear drain plugs.

6. Remove both hydraulic reservoir drain plugs (A), located under the skid steer, and drain fluid.

7. Dispose of oil properly.

8. Install drain plugs (A).

9. Fill reservoir, through hydraulic oil dipstick tube, with John Deere HY-GARD or low viscosity HY-GARD (cold weather operation only) oil. Reservoir capacity is 15.6 L (4.1 gal).

10. Check reservoir oil level.

11. Inspect drain plugs for leakage.

12. Install skid plate.

13. Close engine cover and rear service door.

Inspecting and Changing Hydrostatic Motor Return Filters (one on each side)

NOTE: Inspect hydrostatic motor return filters every 1000 hours. Change filters every 3000 hours.

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

2. Raise ROPS and assure ROPS is safely in the locked position.


KV0581

3. Remove two hoses (A) from each filter.

4. Remove each filter (B) from bracket (C).


KV0584

5. Remove end cap (D) from each filter by rotating counterclockwise.

6. Inspect each screen (E) for contamination.

If screen is clean:

Assemble filter and install.

If screen is contaminated with metal filings:

See your Authorized John Deere Skid Steer Dealer.

7. Install each filter in mounting bracket with small end up.

8. Connect the two hoses to each filter ensuring hose from hydrostatic motor is connected to the small end of filter.

9. Lower ROPS.
