The manual says 90w oil should be used. This is no longer available, but 85w140 seems like a good compromise. Unfortunately, most 85w140 seems to be GL-5, which is not compatible with yellow metals (copper bearing). I do not know if a JD40 has any yellow metal in its trans, differential, or final drives, but if somebody knows, that would be appreciated. GL-4 oil appears to be quite hard to find.
Any comments on the quality of the Tractor Supply brand (traveler) vs. other brands? What about Walmart's SuperTech?
Any problems doing the kerosene flush recommended in the manual?
Thanks!
