There are over 2500 John Deere distributors/dealers in the U.S. and Canada and any one of them can get in a few tubes of the Corn Head grease with a couple day's notice. At $2.99 a tube the price is right and my AD box needed about one and a half. The easy way to fill the box is by using a cake decorating bag.
