Thanks for the help guys! I'll call around and get some corn head grease. I feel a lot better about the purchase now. Again, thanks for your input!

What's so unique about corn head grease ?

It heats up and gets fluid around the gears, but keeps a heavier consistency elsewhere. Check out this video. JESCO/John Deere Corn Head Grease - YouTube
That's basically how I understand it as well...it is sort of multi-viscosity. Looks like regular grease when you pump it in, but behaves like more of a fluid when the gears are hot.
Maybe regular ole grease would work just as well. I certainly thought about it. But I've been using the corn head for a while now and my experience says it does the trick. I'm not generally one to stick with the "but that's the way we've always done it" line....but **** if it doesn't do the trick. Sure beats actually fixing the gear box!

Good tip on the corn head grease.
The seals on my bush hog went years ago, filled it up with gear oil and a tube of grease, been fine for 15 years now.

Late comments: Yes, the typical "fix" for leaking mainshaft seal is to put in grease instead of gear oil. Yes, many dealers recommend cornhead grease. The reason is that cornhead grease is formulated to cling to the gears. But BY FAR the most common practice is to use "00 Grease." Your friendly Tractor Supply sells "double zero grease" in a squeeze bottle the same shape and size as 90 wt gear oil. I hear it is used all over the south for bush hogs and has been for years. It is a heavy lube somewhere between gear oil and much closer to grease gun grease. Not quite the same as "cornhead grease" but easier to put in using the squeeze bottle. In my view the "00 grease" is fine and unless the seal is so bad that it won't stay in the gearbox you'll be fine with it.
