Service Lubrication

Grease


IMPORTANT: Avoid damage! Use recommended John Deere greases to avoid component failure and premature wear. The recommended John Deere greases are effective within an average air temperature range of -29 to 135 degrees C (-20 to 275 degrees F). If operating outside that temperature range, contact your Servicing dealer for a special-use grease.

The following greases are preferred:

• John Deere Multi-Purpose SD Polyurea Grease

• John Deere Golf & Turf Cutting Unit Grease

If not using any of the preferred greases, be sure to use a general all-purpose grease with an NLGI grade No.2 rating.

Wet or high speed conditions may require use of a special-use grease. Contact your Servicing dealer for information.

Transmission and Hydraulic Oil


IMPORTANT: Avoid damage! Machine is filled with John Deere HY-GARD™ (J20C) Transmission/Hydraulic Oil at the factory. DO NOT mix oils. DO NOT use type “F” automatic transmission fluid.

MIF

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

John Deere J20C HY-GARD Transmission/Hydraulic Oil is recommended.

Use John Deere BIO HY-GARD™ oil when a biodegradable fluid is required.

Biodegradable Oil

Application


IMPORTANT: Avoid damage! Biodegradable oils, other than BIO HY-GARD™, are not recommended.

When use of a biodegradable lubricant is desired or required, BIO HY-GARD is recommended. BIO HY-GARD may be used under normal mowing conditions.

DO NOT USE biodegradable lubricants in machines for the following operations:

• Any machine used for scalping procedure.

• Any verticut operation in temperatures exceeding 32?C (90?F).

• Mixing of biodegradable oil and mineral oil will reduce the biodegradability of the lubricant in the machine. Mixing of HY-GARD and BIO HY-GARD will not result in performance deterioration.

Cold Weather Operation

Precautions should be taken if BIO HY-GARD containers or equipment are stored for long periods of time in extremely cold temperatures. Freezing should be expected if BIO HY-GARD is subjected to the following temperatures:

• Stored for six months at -18? to -23?C (-1? to -10?F)

• Stored for seven days at -23? to -26?C (-10? to -15?F)

• Stored for three days at -26? to -29?C (-15? to -20?F)

• Stored for two days at -29? to -34?C (-20? to -30?F)

• Stored for one day at -34?C (-30?F) and below.


IMPORTANT: Avoid damage! Equipment should not be started or any operation attempted until BIO HY-GARD™ has reached a safe operating viscosity.

If freezing of BIO HY-GARD is suspected, the container or equipment MUST be warmed to at least 0?C (32?F) and maintained for 24-48 hours to ensure the fluid has reached a safe operating viscosity.

Converting From HY-GARD to BIO HY-GARD

Systems being converted from HY-GARD to BIO HY-GARD should follow the procedure listed below to obtain maximum lubricant biodegradability.

1. Park machine on a level surface.

2. Stop engine and set park brake.

3. Drain gearcase.

4. Fill gearcase with BIO HY-GARD to appropriate level.

5. Start engine and bring to medium idle.

6. Cycle cutting reel several times.

7. Stop engine and check hydraulic oil level. Add BIO HY-GARD to appropriate level.

8. Operate machine under normal operating conditions for a minimum of two hours.

9. Repeat steps 1-7.

10. Follow recommended service intervals.
