Characteristics of fishing line for trimmer

At the moment, there are a huge number of manufacturers of fishing line for trimmer, each of which produces this consumable of different types. In order to choose the material of the desired type, you need to know about the features of each and those characteristics that distinguish them.

Typically, fishing line is classified according to the following criteria:

For almost all lawn mowers, cords with a thickness of 1.4. 4 mm are suitable, but still, before you rewind the fishing line on the trimmer coil, you need to find out what thickness is needed for this or that device. This information is written in the instructions for the device or on the universal bobbin.

If you select a very thin thread for the device, you can significantly increase engine wear. If an overly thick cord of about 4 mm is used, friction increases, as a result, the engine, working hard, will gradually fail. Damage will not happen immediately, but, as often happens, the engine will fail at the most inopportune moment.

The thickness of the cord can be recognized by the type of lawn mowing engine and its power source. If the device is powered by mains or battery, and its power does not exceed 1 kW, then you do not need to purchase a thread thicker than 2 mm and much thinner. The effective operation of a trimmer with a power of 500 W will be ensured using a thin thread of 1.6 mm.

Petrol trimmers are distinguished by the fact that in them, thanks to engine power, it is possible to thread a thick thread of 2, 4. 3 mm. She can easily overcome the most persistent herbs with thick stems and even some types of shrubs. The operation of such a cord is much more profitable than thin, since it is not necessary to change the fishing line very often.

Composition of fishing line for trimmer

The correct composition of the cord determines the time and effectiveness of the lawn mowers. Typically, fishing lines are made of nylon. This material is resistant to wear, and can also be used under active loads and works well with temperature differences. Nylon retains its positive qualities for a long time and does not wear out much during prolonged use.

Cross sectional shape

Usually, a fishing line with a round cross section is chosen for the trimmer, it is most practical, according to the owners of the electric scythe. In addition, such a cord is characterized by a relatively low price, compared with other species, and positive results in mowing. But this form of cross-section of the fishing line contributes to the appearance of a loud sound, similar to the hum of a motor, when working with a trimmer. If there is a need to reduce the noise coming from the trimmer, then you can replace the trimmer fishing line with a spiral one.

In addition to these, there are also threads with square, rectangular and star sections.

There are also cords with dents and notches along the entire length. The use of such a cord with a thickness of 4 mm is necessary only in addition to powerful trimmers, which work on neglected and overgrown weeds. With the help of such a thread, the trimmer acquires great power, and the sound made by it is not so strong.

For this thread, special heads are installed on the trimmer, on which the fishing line is wound. Such material is able to cope even with some types of shrubs. But this cord is consumed very quickly, and its price is quite high. It is best to pre-install special disks on the trimmer, on which to mount this line.

There is also a twisted fishing line for the trimmer, which is designed to mow dead wood. It has a circular cross section and an inner core made of another material. This cord is known for its tear resistance and high structural strength, even with a thickness of 1.4 mm. But, such a thread can be used only on trimmers that run on gasoline. Its cost is high, so you can purchase it if you have a job that can be dealt with in a couple of days. Continuous use of this consumable material greatly undermines the budget.

The choice of fishing line and the nuances of working with it

What kind of thread to purchase is chosen only by the owner of the trimmer, but he must observe certain conditions so that the wrong choice does not entail the failure of the device itself:

The thickness of the thread must be selected in accordance with the parameters specified in the instructions or according to the type of engine. For example, a cord 4 mm thick is not suitable for a weak trimmer.

The cross section of the fishing line is suitable for mowing different types of vegetation. For young grass on the lawn, you can safely get a thin line with a round cross section, but mowing perennials with a thick stem requires fishing lines with sharp corners in cross section. She will cope faster and more efficiently, without overloading the trimmer.

When mowing, you need to try so that the fishing line does not come into contact with solid objects, since it grinds faster and the consumption will be higher.

You do not need to buy the most expensive cord, since often the price is not an indicator of quality, and for a simple mowing of slightly grown grass, too expensive fishing line is not needed. A more budgetary one can cope with such a task, which in thickness can be less, from about 1.2. 1.4 mm.

How to Fill a Fishing Line into a Trimmer Coil


The fishing line for the trimmer is not just a consumable, but one of the main elements that can both increase work efficiency and reduce it if the choice is not in favor of the desired model. If you choose the right cord, then there will be no problems with mowing not only fresh grass, but also dead wood.
