Hopefully I've attached an image of a tube of John Deere Corn Head grease. A few years ago the only way to get it was to purchase a case of 12 from the local John Deere dealer by special order. I split case of 12 tubes and cost with others in my local car club.
I was told that this grease was developed for use on the corn combines for lubricating the cutter heads which see long,dry and dusty conditions on the hot farm fields cutting corn stocks near the ground were standard grease would just not hold up. Not sure if this is truth or fiction, you can decide, but no matter as it's the lubricant I'm going to use for the universal joints.
