corn head grease apparently liquifies when ..working then gels up again after it stops working under load.
in any event don’t worry about it and use quality 90 grade marine products and recheck for leaks during mid season .I doubt a quality marine oil is cause for concern .

First if we are talking about early gear cases that aren’t
sealed there is more to consider than just the gears.
What you choose must be fluid enough to move through
the bearings or bushings as well but not so fluid that it
just runs out. The original lubricants are no longer
produced except for Lubraplate 105 although it is not
packaged as a gear case lub. any longer. John Deere
corn head grease is also an excellent substitute for the
lubricants. In gear cases that are sealed gear oil is the
best choice because it can easily get to the bearings or
bushings as well as protect the gears without leaking out.
If you have a sealed gear case and the seals have failed
that must be addressed.
If for some reason it can’t be repaired 105 or corn head
grease may be an option but if you can keep the water
out gear oil is always the best choice.
