I will start by first describing how a nylon line cuts, for those who have not thought about. I have a Stihl 250 weed wacker and keep having problems with the nylon line, the 4mm line which is the heaviest gets destroyed quickly on heavy weeds. Why does the nylon line on my line trimmer keep breaking at the head?Ĭan you tell me why my Stihl weed whacker line keeps breaking? SO TO ANSWER THE QUESTION, which I have now been asked very similar questions on three occasions now. Over the years using a nylon line, I tried many different brands of line and different thickness, but eventually ended up settling with a medium thickness Husqvarna dimple line. I wasn’t till we purchased our current rainforest property that I again had a need for a metal blade. I t used to be very satisfying to sit back and watch the shadows of the trees move as the sun set at the end of a hard days work. You would actually be amazed what you can cut with a nylon line, with the right technique.Īfter several years we had 50 odd acres of hillside and all around the dam manicured like a golf course, so I can assure you I have spent countless hours on the end of a brush cutter. I used to trim around every tree and rock, to give a crisp sharp line between it and the grass. The photo below is the early days of starting to tame the hill side and around the dam. The blade that came with the Honda was a four star knife blade which turned out to be totally useless against the grass and bracken, so I tried a saw type blade which was OK until I hit my first stone and then it was totally useless.įor the next eleven years I used my brush cutter a lot cutting everything that shouldn’t have been possible with a nylon line, first on the 10 acre block and then a 100 acre block. I bought my first petrol powered Honda brush cutter in 1999, with the initial intention of using a metal blade on long grass, bracken and blackberries on our first 10 acre block. Like everyone else, I was breaking the lines on my very first electric Weed Eater in the mid 1980’s and quickly worked out what was needed to prevent this from happening. Having an inquisitive engineering mind, I quickly became aware of this problem and figured out the reasons why.
