JOHN DEERe recomends using JD Low viscosity Hy-Gard Transmission/Hydraulic fluid in it's equipment. Please check your owner's manual for any specific requirements, if one is available. There is no equivalent on the market that I could find. The fluid keeps solvent in low temperatures and can be used in Transmissions and Hydraulics, separate or common resevoirs. I am not a John Deere expert..just a owner/user. From a web site... Hy-GARD® JDM J20C Transmission and Hydraulic Oil
