430 gear box leaks

When doing routine maintenance, I saw the gear box was real low. Following the specs from the manual, I filled it with 85-140 oil. Now I see it is leaking. What advice can you give me?
 
430 what? JD tractor, 4 row 30 inch cornhead, or? Cornhead grease is a temporary fix for a bad seal.
 

Which gearbox? Steering gear? Cornhead grease is OK. Transmission? No way. Although if you are in the far south, you can get away with straight 140 if you can find it. Final drives? No way. But maybe 140 again. Ya gotta be more specific for the best answer.
