Service Lubrication
Grease
IMPORTANT: 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 Multi-Purpose HD Lithium Complex 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.
