Yes, there is some question Hy-Gard vs. 80-90 Gear oil. I have three manuals for the 6620...each with a different OM number. Two of them say to use 80-90 Gear oil, and one says use Hy-Gard. No dates in the manuals. Talking to JD folks the consensus seemed to be use gear oil...but I gotta hunch either is okay:)
Hi mates I have an old John Deere harvester, model 1068H. The transmission is manual type, and I want to change the fluid, but I don't know what kind of viscosity and specification to use. Can you give me your opinion? Regards!
My owners manual says to use Hi-guard fuild.
