The fishing line is called the consumable material, which consists of nylon, and serves as a cutting device. This accessory is used to cut the grass, which is made possible by the high frequency rotation of the tool head. This material has different thickness, which depends on its application on the respective tools electric low-power (1 to 1.6 mm), electric from 500 watts (2-2.4 mm) and gasoline grass trimmers with brushcuts (2.4 to 3.2 mm).

The more powerful the tool, the thicker the cutting equipment must be, respectively. This affects not only the quality of grass mowing, but also the service life of the material. If you’re wondering how to wind the grass trimmer reel, then it’s time to change the reloading tool. With the onset of spring, this issue is becoming more and more in demand, so it’s time to figure out the step-by-step instructions for replacing the line in the grass trimmer reel.

How to choose a fishing line for a grass trimmer

Before considering the rating of the best manufacturers, let’s touch upon the criteria for selecting the line itself for the grass trimmer:

  • Cord material. When buying a line for your trimmer, you need to know what it’s made of. The more plastic the material, the less likely the string will break. The best choice here are polyamide monofilament and nylon. For particularly rough grass (e.g. burdocks) use reinforced grass cutting equipment with steel wire inside.
  • Section shape. The line for trimmers is available in four configurations. Round is considered universal and is used for mowing all kinds of vegetation. It also winds easily onto the bobbin. A sprocket and square, due to the pronounced edges, easily cut coarse and overripe grass. Twisted line makes up to 50 % less noise than other lines, so it is ideal for continuous work.
  • Diameter. The value ranges from 1.3 to 5.0 mm. It determines the strength and load on the motor. 1.3-2.0 mm are suitable for trimmers with 0.7-1.0 kW. 2.4 mm is the choice for electric trimmers with 1.4 kW as well as semi-professional brushcutters. 2.7-5.0 mm. this is equipment for professional gardening equipment.

Manual or mechanical spools and their purpose and use

The first grass trimmers were produced with manual reel types, which have a primitive design. They consist of a plastic or metal disc that has holes to hold the line. The holes are appropriately sized, allowing you to use a cord (line for trimmer) of a certain diameter. However, this is not the only disadvantage of this equipment, as another disadvantage is the need for frequent refilling of fishing line. Below is a variant of the simplest spool with a fishing line for a grass trimmer.

After the simplest reels appeared mechanical type heads, inside of which is installed a spool with a skein of fishing line. Such devices are excluded by the disadvantage of fast cord consumption, but to feed a new line, it is necessary to interrupt the work of mowing the grass. The head is equipped with a manual regulator for the filament feeding, through which the line is pulled. Today, manual models are rarely used, which is due to their great disadvantage. the need to stop work and turn off the engine in order to lengthen the cord.

What materials are used for the line and how this affects its reliability

Nylon is used for trimmer lines, which are based on polypropylene with polyamide. Distinctive features of nylon are its following advantages:

  • Durability in compliance with storage conditions. Do not leave the material in the sun or at low temperatures for a long time
  • Lightweight, which allows high speeds through the inertia of the head rotation
  • Wear-resistant. the material is resistant to wear and the filament is damaged only when hard obstacles are encountered
  • Low cost. this is convenient, because the material is consumable, and it requires constant use of new fishing line

This is interesting! Nylon trimmer line breaks into pieces when you cut the grass, and the pieces remain in the cuttings. These pieces are harmful to animals, so mowing with a fishing line for hay-making is not recommended.

Sometimes cheaper polyethylene is added to the material, which reduces the reliability of the cutting equipment. Cord from polyethylene wears out faster, so experience proves that it is more advantageous to buy a line for a trimmer made of natural nylon (it costs more) than to save money and buy a polyethylene cord.

The lines from 2,6-3,3 mm thickness consist of graphite or steel rods besides nylon. two-component cord. Rods not only make the grass cutter more efficient, but also reduce the rapid wear and tear on the line. As a result, it turns out that a string with a larger cross section lasts longer than a thin line for the trimmer. There are also cords with added metal particles in their composition. These additives are also designed to increase the efficiency of grass trimming, and increase the strength and wear resistance parameters of the material.

This is interesting! When choosing a fishing line for your grass trimmer, you need to pay attention to the head or spool. On these parts, the parameters of the cross section of the cord allowed to be used are indicated.

How to store trimmer line properly or increase the service life of your trimmer

Many people give advice on how to choose grass trimmer fishing line, but few give information on how to store it. Improper storage causes the line to wear out quickly when cutting the grass. After buying a 15-foot reel, few people ask how to store trimmer line for a trimmer. When buying a 250-500 meter reel it is very important to understand the storage conditions.

Loss of original line performance. is a real nuisance, so let’s learn what you can do to extend the life of your line during storage. Nylon material is the most susceptible to ultraviolet light. The longer a trimmer line is stored in the open sun, the faster it loses its technical properties. The following are instructions for extending the life of your grass trimmer line:

  • At the end of the season, after a long break, wrap the cord in polyethylene and soak it in grease (glycerin) beforehand. Tightly wrapped and oiled fishing lines should be stored in a dark place at 5 to 20 degrees (refrigerator is best).
  • Do not store lines for trimmer on radiators or heaters, because excessive heating leads to deterioration of technical properties.
  • To avoid full exposure to light on the line for the trimmer, it is better to wrap it in black, not in transparent plastic. Special plastic airtight containers can be used instead of a bag

When the season comes, remove the roll, wrap the necessary amount of material, wipe off the grease and load it into the grass trimmer drum.

What’s the best material

Another important indicator by which to judge the durability and quality of the line is the material used in the manufacture of.

In general, in most cases, a good line for the trimmer is made of nylon. polyamide or polypropylene. This material is inexpensive, lightweight, and hardwearing. Unfortunately, many manufacturers cheat here as well by adding polypropylene to nylon. Of course, officially they declare that this is done solely to reduce the cost of consumables. In fact, the price is only slightly reduced, but the service life is quite noticeable. Such a line for a trimmer will wear out much faster, and overheating during prolonged work and can ruin it in the shortest time. Therefore, if available, a nylon line for a trimmer would be the best choice. Its price is quite affordable, and it has a much longer service life than its cheaper counterparts.

Under no circumstances use a wire or metal rope instead of a fishing line. High rotation speed in combination with the hardness of the metal can lead to the fact that they will cut through protective equipment and even shoes, causing the user a serious injury.

But that’s not the end of the range. You can also find two-component lines for trimmers on the market. Most often this applies to materials with a larger cross-section. from three millimeters and larger. A regular nylon trimmer line has a steel or graphite rod inserted into it. Working with such a trimmer requires special care, but the aerodynamic properties of the line are improved dramatically. now the thickest and hardest stems and even thin twigs will be cut quickly.

In addition, you can see on sale special reinforced lines for trimmers, in which grains of steel are distributed throughout the volume of nylon. The main advantage of this material is very high wear resistance and durability. It is much more expensive to buy than the ordinary nylon or, even more so, the polyethylene analogue. But the service life will also be significantly higher. So you won’t regret wasted money: one skein will be enough for several years of work on a country site.
