The Golden Boy Lawn Edger is a piece of lawn & garden equipment that was once sold at Kmart. They have been discontinued and finding manuals and replacement parts can be difficult. The manufacturer can no longer be contacted for these things. There are people around who also own this same edger that are willing to help. They have formed an online group in which owners can sell and trade parts. You might be able to find a manual at http://groups.yahoo.com/group/golden_boy_edgers/?v=1&t=directory&ch=web&pub=groups&sec=dir&slk=41.
