Why FS-55? I made my choice based on the need for a more powerful mower. To replace the FS-38. Because in addition to simple grass, there are also tall nettle bushes, burdock and small bushes, trees. When mowing such thickets, the power of the 38 was not enough. And the handle is not comfortable at all, it is for gripping one hand, which affects fatigue when working long hours. The 38 also has no vibration dampening system, so after 30 minutes of working with it, my hands are gone and sore. And the protection against grass discharge is weak, the grass flies in different directions. When I bought the new model, i.e. 55, I wanted a braid with a more powerful motor, more comfortable and handy, so it could be used not only by me but also by my wife. Convenience criteria for mowing in hard to reach places using a blade instead of a mowing line of hair growth were also important. Well, even the minimum of maintenance and upkeep. In fact, I can say that he did not regret his choice. After two months of working with it, I have no complaints. Even my son, who is 8 years old, can operate it. And his wife is comfortable using it.

Cord extends spontaneously

There are situations, when the user of the grass trimmer notices very fast line consumption. At no time did he hit the button on the ground to lengthen the line. The reason why the line is unintentionally lengthened by cutting it on the special blade on the top casing may be due to the lack of a spring in the mowing head. Often first-time mower users, trying to load line into the reel, forget to install the pressure spring in the head, or lose it altogether when opening the cover, and later, do not even suspect about its existence.

Also, the line can be extended without using the button, if the spring is loose. If checking the spring confirms this fact, you need to put some washers under it to strengthen its clamping properties.
