Folks Due to ill health my "garden" (it is 1 acre) has become very overgrown with grass, nettles & brambles. Over the last two weekends I have managed to cut the grass down to a nice looking level again (phew) Yesterday I bought a nice new straight pole petrol strimmer/brush cutter. What could go wrong here you ask? Well the cutter disc does not really like long grass or nettles. It pushes them rather than cuts them so it binds up. The strimmer line is nylon with a metal cord in it. This breaks every few seconds, so is not sustainable. Can anybody recommend a really strong line that will withstand industrial nettles? PS. Previously I was using a square orange nylon line, but I can't find this anymore. I want a professional gardeners line. This is more agricultural rather than garden. Unfortunately my back is more jelly than iron.
