Main parameters

The main determining values ​​are the composition and diameter of the thread. Material greatly affects durability. Production takes place from nylon, because it is considered the most wear-resistant working material. Now aluminum products have begun to appear. They are even more effective.

And to determine the approximate diameter is possible by type of engine. Electric trimmers with a power of 1 kW will require a product 2 mm thick, less than 500 watts. Not thicker than 1.6 mm.

For lawn mowing, 2.4-3 mm cords are taken, for lawn mowing. 3.2 mm. It turns out that the more powerful the scythe, the more equipment. Pay attention to it.


There are options with notches and recesses, which are allowed to mow impassable weeds. The volume level is small, additional power is given.

Similar cutting devices are installed on lawn mowers before working in forgotten overgrown territories. Twisted fishing lines are ideal for dry grass, but their cost is higher than standard.

Steel Center Thread

To combat really problematic areas, sellers recommend a fishing line with a metal core. They serve longer, cope in difficult conditions. Reinforced metal threads are used for professional purposes.

The core increases the resistance to tearing. They can be square or round, approximately 3 mm thick. Naturally, such are higher, but the result of mowing is excellent.

Which fishing line is better?

A definite answer to this question cannot be given. The round species are universal, and in the form of stars, cords are not suitable for everyone. Experienced workers believe: the right choice of thread will increase productivity, a quarter will save time cleaning the yard.

It is necessary to take into account the category of device for which it is planned to purchase a cutting device. It is believed that twisted wires are best suited for beveling all trimmers (except gasoline ones. They should give cords with metal in the center). Spinning fishing lines easily cut grass, which can not always be said about smooth ones.

The thinner the threads, the easier the bevel, but their wear resistance is less, they break quickly or wear off. And thick ones overload the device, ruin the lawn, as they wrinkle greens.

If you do not like twisted, then take a rounded line or that line that you think is better. Many recommend taking a brand invented by the same company as the trimmer.


So, when you decide and buy a scaffold for a scythe, the following problem will arise: how to refuel it? It will take about half an hour, if you haven’t done this before.

The cord is wound on a trimmer coil, which is a plastic case with a cassette inside, on which there is a small hook for winding. The standard type of attachment is a screw button. When you click on it, you can pull the thread of the required length. The method of winding is almost the same.

    The following is a common case with two antennae. Loosen the center screw clockwise. Use a screwdriver to disassemble the head. Take out the coil. Measure the standard length of the fishing line (2-4 m), cut and fold in half, and then just start winding it onto the removed part.

    Its ends will be opposite to each other. Pull them out through the small holes for fixing and reassemble the head in the opposite direction. Make sure that the ends do not slip out.

    Replacing fishing line

    When mowing grass, it may end or break off. Therefore, you need to replace the cord. You will need the cord itself, gloves (you can without them, as comfortable) and a knife. Unwind the required size from the pack and cut it off. You can hold the piece for half an hour in water. It will become more flexible and durable.

    Press the tabs or unwind the lamb to insert the thread into the spool. Remember how the spring and the fixing screw are located so that there are no problems during assembly.

    It is worth putting the elements in a certain order near you. Then start winding the fishing line in the same way as during the first refueling. Do it carefully, without pulling, because the threads need free play. Also bring the ends into the slots.

    After that close the lid, tighten. Place the mowing part on the trimmer and pull the line to the desired length. Now you can continue to work.
