This is a vintage John Deer Sulky Rake Operator's Manual (OM-H6-446).  It has information regarding lubrication, operation, maintenance, setting up and repair parts for this sulky rake. It has pictures, diagrams, exploded views and part numbers. The book is very old, I am guessing 30’s or 40’s. The book has some tears and other signs of age and use but still very readable and usable. Perfect for the John Deere collector.
