Corn head grease came out partly because the stalk roll seals in Deere corn head gear boxes were letting 90wt get by and they needed something thicker in them to stop the leakage. The gear boxes are high speed and you know what happened when all of the 90wt leaked out. Your gear box is moderately high speed and a seal leaks a little. Corn head grease is the perfect fit for you.
Getting off the subject a bit, I always wondered why IH corn head gear boxes could hold 90wt OK but Deere's could not. The gear boxes are darned near identical, in fact there was a patent infringement brought on by Deere over it. We used to run a Deere 843 head and a IH 1083 corn head side by side on identical combines. 80-90 went in the IH gear boxes and corn head grease went in the Deere. Both heads were speeded up to the max and run 6 MPH. Both brands needed to have the gear boxes topped off with about the same amount of lube in about the same amount of hours.
