After nearly putting my shoulder out pulling on our weed whacker to get it started I am looking for a key start machine. Does such a thing exist? I tried a battery operated one (Craftsman 18V. 12" model) but it was not nearly powerful enough. It just sort of licked at the grass and after 5 min. wore down. Another thought was an electric. But I would have to have so much cord to cover 1.4 acres. Just can't continue to wreck my shoulder with a gas engine one, though.

Help!
