I believe corn head grease is close to 00 but may be slightly thicker, not sure. The 00 I use which is the same grease/oil that every Snapper dealer should have is also known as cotton picker spindle shaft grease. Ask for it at a TSC store. I was a Snapper dealer for years, and used it for all gears and chains on all snapper equipment including worm gear boxes on tillers and snowblowers.
