My Mclane lawn edger is down. I can't seem to find them at Home Depot anymore, and Mclane website wants twice as much. I read in some old posts that this had already started as a problem last year. I've had mine since 2005. It's a 101 3.5, Briggs and Stratton. Any advice to maybe fixing it or where I can purchase a new one? I paid $300 for mine two years ago.
