Hi all, My dad just dug this old Planet Jr. seeder out of the attic in the Ell of my grandpas farmhouse. As I understand it my great-grandpa bought it new or almost new and used it in his garden for years and then my grandpa used it for a while before it was put away. My dad wants to use it so he and my niece can plant corn this upcoming week. The problem is my great-grandpa has been gone about 36 years and my grandpa doesn't remember how to set it up. I've looked around and can't find an operators manual for it anywhere. Does anyone happen to know where I could find one or know how to set it up properly for corn? Here's a few pics of it since they made so many different ones. Thanks in advance, Stewart
