Have an overgrown arborvitae at my parents home that needs work and a new hedge at home, so I see the future need for a hedge trimmer. The hedge at my parents place has been severely neglected, so I did some rough cutting with a chainsaw, but I need a better tool. Not an area of personal expertise, so I thought I'd ask. I'm thinking that I'll need a robust tool to deal with finger diameter growth of my parents hedge that needs to be cut.
