I've always trimmed with the trigger in my right hand and walking left to right. The trimmer then throws all of the grass away from me, but towards not only beds, but windows, cars, etc. If I walk backwards the grass flings towards me, which is a safety concern, plus I'm walking backwards. Has anyone forced themselves to learn to trim in the other hand? If I would put trigger in left hand and walk right to left I would have the best of all of the options. Clippings would fling away from "danger" areas but also slightly in front of me.
Worked at a lawn company around here and we had a guy fall into a fire escape that was uncovered while he was trimming backwards.
Also wonder what difficulties would arise by requiring all future employees to trim same way.
