Hydraulic System Oil
Use oil viscosity based on the expected air temperature range during the period between oil changes.
The following oils are preferred:
-
John Deere HY-GARD
®
-
John Deere Low Viscosity HY-GARD
®
Other oils may be used if they meet one of the following:
-
John Deere Standard JDM J20C
-
John Deere Standard JDM J20D
Use John Deere BIO-HY-GARD
oil when a biodegradable fluid is required.
NOTE:
BIO-HY-GARD meets or exceeds the minimum biodegradability of 80% within 21 days according to CED-L-33-T-82 test method. BIO-HY-GARD should not be mixed with mineral oils, because this reduces the biodegradability and makes proper oil recycling impossible.
