Pulled muscles in my back trimming a large row of forsythias yesterday. Every time I take breath feels like I'm getting stuck with a knife. Standing on my ladder over extending both arms straight out with heavy trimmers. I should have known better. Hurts so much I have a hell of a time just climbing in and out of the truck. What is a good alternative to hand held trimmers? Is there an attachment for a trimmer that would be easier to use? I thought I saw a guy using something like that for hedges on a hill.. Let me know what you guys use for shrubs that are out of reach. I can't keep doing them the way I was.
