How to choose the thickness of the trimmer line

How to choose a line for brushcutters, trimmers

Choosing the right thickness and shape for the correct line can sometimes be a real challenge for trimmer or brushcutter owners. Below we will try to explain how to choose the right fishing line.

There are two most common line shapes: round and rectangular. Each is suitable for a different purpose. The round shape of the fishing line is intended for mowing grass near curbs, trees and where it is likely that, in addition to grass, it will come into contact with hard objects (small tree branches, for example), thereby the wear resistance indicator will be negative. Angled line and its profile are more suitable for mowing. Its sharp corners cut the grass better. But as a rule, such a line is a little more expensive, and when it comes into contact with hard objects, it will also wear out like a round one, based on this, the cost of cutting will increase.


Vendors usually offer fishing line from different materials, it is color-coded and for a comfortable mowing you will be quite satisfied with the average quality of the line. Basically, people buy the cheapest option, but the cheap line tends to break and wear off quickly.


Naturally, everyone would like to use thick line, but the ideal diameter should be specified in accordance with the characteristics of the particular brushcutter (trimmer) on which the line will be used.


For small trimmers with a power of about 450 W and the location of the electric motor in the lower part of the trimmer. the cutting head, it is better to use a line with a diameter of 1.3 mm. If the trimmer has a torque limiter, 1.6mm line can be used, but there is a significant possibility of trimmer overheating. With such a line, the trimmer should mow no more than 10-15 minutes. After that, the trimmer should run idle, and then you need to turn it off for 15 minutes.


For more powerful electric trimmers from 600 W, which have an electric motor in the upper part of the trimmer. the handle, a line diameter of 1.6 mm is used. For power over 1000 W, a 2 mm line can be used. You can mow for a longer time with these trimmers. Also powerful models can be used for mowing larger areas.


For brushcutters, a fishing line with a diameter of 2 mm or more is used. In the characteristics of the brushcutter, as a rule, the maximum line diameter is indicated. Brush cutters are more powerful than electric trimmers and are designed for large areas.


Mowing heads (spools) are divided into three classes: hobby, semi-professional and professional. For cheaper mowing heads, fishing line with a diameter of up to 2.5 mm is used, and for semi-professional middle class. up to 2.7 mm, and 3 mm for professional expensive mowing heads (spools). The thicker the line, the faster the mowing head wears out and breaks, and the line jams in the mowing head.

How to choose a trimmer line

Mowing string, cord, trimmer line. as soon as this consumable for trimmer heads is not called. We will use Husqvarna terminology below. cord cord.

On the Belarusian market, cord cords are presented in a wide range from different manufacturers, different colors, different diameters, different sections. What are the differences, how to choose the most suitable one? Let’s try to figure it out and answer this question.

First of all, cords differ in material composition. It is only at first glance that the differences are invisible. But you probably had to face a problem when the cord cord, just tucked into the trimmer head, breaks off when it comes into contact with a stone or a thicker stem. I had to turn off the engine, disassemble the trimmer head in order to release the ends of the cord again. But literally, after 5 minutes everything was repeated again. Only the torment of such work. I can say with full confidence that you purchased a low-quality cord cord and the manufacturer saved on plasticizers.

choose, thickness, trimmer, line

Cord cords are divided into 4 types according to the section type:

  • round
  • square
  • star
  • twisted or silent.

What is the difference between branded fishing line and low-quality consumer goods

Large manufacturers of garden equipment (for example, “Stihl”, “Husqvarna”, “Oleo-Mac”), producing cord cords under their own brand, use the latest technologies for manufacturing cord cords from polyamide monofilament with high nylon and special additives that provide high wear resistance and great internal tensile strength. Special plasticizers give the material softness and considerable flexibility. In addition, the surface of the cord is treated with a soluble oil, which prevents sticking and sintering of the cord in the trimmer head.

    Line composition

    It is the composition that determines the service life of the line. It is often made from nylon. It wears out slowly and improves performance efficiency at high temperatures and heavy loads. The material retains its working properties for a long time, low temperatures do not affect it, as well as prolonged work.

    Coaxial trimmer line is considered one of the strongest. It has a dense core, and therefore wears out gradually. Such a line is difficult to cut with a knife and creates little noise during operation. Also now there is a fishing line, which includes inclusions of aluminum.

    Thread thickness

    You can find out about it by reading the performance of the trimmer or by referring to the dimensions and inscriptions on the universal bobbin. Typically, for trimmers, threads with a diameter of 1.2-4 mm are used. True, for each device you will have to select a line of a certain diameter.

    A trimmer thread, thinner than the required one, will not immediately damage the engine, although it will significantly increase its wear. If you use a thread that is thicker than necessary, the resistance to rotation will increase, the motor will work harder, overheat and, as a result, break. True, a lot depends on the engine itself.

    You can also find out the approximate diameter of the fishing line for the device by the type of engine. If the trimmer is powered by electricity or a battery and its power is 1 kW, you will need a cutting thread with a diameter of 2 mm, and if its power is less than 500 W, use a line of no more than 1.6 mm.

    For a gasoline trimmer, the line is chosen with a certain diameter. 2.4. 3 mm. The choice of such a thick fishing line is associated with the peculiarities of gasoline units. they are more powerful and more efficient than their electric counterparts. Thick line can be used for a long time, in addition, it can easily overcome long-term dead wood.

    The main parameters of the trimmer line

    Fishing lines can be classified according to the following parameters:

    • Thread thickness;
    • Sectional shape;
    • Line composition.

    How and which line to choose for a trimmer

    People who work in the country may need a trimmer, however, not everyone knows what it is, how to choose a line for a trimmer, and what it is for. A trimmer is a device that allows you to carefully cut grass near trees, fences, paths. The operation of the device depends on the type of equipment, which is often used as a cutting line. It affects not only the external condition of the lawn, but also the performance of the trimmer. The main requirements are that it must bend, have strength and rigidity.

    Line selection for the brushcutter

    What line to choose for a trimmer is thought by each of its owners. It should be chosen based on the following parameters:

    • The diameter of the trimmer line must be suitable for the engine power. In terms of parameters, it should be combined with the trimmer option.
    • The type of line should be chosen based on the type of vegetation to be cut. If you plan to mow the lawn, a thin line is suitable, for the destruction of perennial weeds. a thicker one.

    to the content

    Sectional shape

    The most often chosen line for electric scythes with a round cross-section. It is inexpensive and the most popular, it mows fresh grass well. Its main drawback is the noise level that is heard when the trimmer is in operation. Line noise is similar in intensity to engine hum. For the best noise reduction, manufacturers suggest using a spiral-shaped line.

    Today they also produce square trimmer line. Of other forms, rectangular and star-shaped are quite often found. Lines with jagged edges and sharp edges are especially productive. These edges cut the grass more evenly.

    There are also lines with notches and dents. They can mow large weeds. The noise level emitted by such a line is low, and due to the increased properties of aerodynamics, the trimmer is given additional power. Such a cutting element is installed on powerful trimmers, with which it is planned to carry out work on overgrown, neglected areas.

    To work with this type of fishing line, special heads are installed on the brushcutter. The fishing line is wound on them. It handles all kinds of grasses (especially weeds) and shrubs. But its cost is quite high. Also, the consumption of such a line is high, since when it is fed from the reel, it can be difficult to remove it. It is usually used with discs, into which it is inserted in small sections.

    There is also a two-piece twisted trimmer line. Its purpose is high-quality mowing of dead wood. It is distinguished by its round cross-section, tear resistance and increased strength. It comes with a core made from a different material. The twisted line is only suitable for petrol trimmers. She is able to cope even with small shrubs. Its main drawback is its high cost. For daily work, it is quite expensive to acquire a twisted line.

    What nuances should be observed when working

    When treating the lawn with a trimmer, it is necessary to avoid contact of the fishing line with rigid elements such as stones, trees, foundations. Contact with them will lead to grinding of the fishing line, and you will have to constantly increase it in length.

    The main cutting element of the brushcutter is a reel equipped with a line for cutting grass. Its price is low, and if you follow the basic rules of use, it will last long enough. Today there are fishing lines that differ in their quality, section, properties. The line, as a rule, is sold in regular rolls in spools, or divided into sections of the desired length, for certain brushcutter models. Therefore, take full responsibility for its choice in order to make it easier for yourself and extend the life of the trimmer.

    What are the differences between trimmers?

    The main difference between trimmers is the cutting width, which depends on the diameter of the circle that the line goes through. Also, the number of lines used by the device and their thickness may differ. The body of the device itself can be made of steel or plastic, which affects not only its efficiency, but also the price, ease of use and durability.

    Trim tabs differ from each other and the type of engines, which may have different power and country of manufacture. If we talk about the type of engine, then devices that run on gasoline are more preferable than electric ones. They are more functional and easy to use. Unlike electric models, petrol trimmers can be used immediately after rain. Barbells are usually presented in two shapes, each with its own characteristics. In straight trimmers, the cutting head is driven by a metal rod, while in curved trimmers it is driven by a steel cable.

    Modern trimmers have various attachments, thanks to which the device can be used for clearing snow, cultivating the soil, pruning trees, forming hedges, etc. Such functionality and ease of use have led to the fact that trimmers are in greater demand than lawn mowers, which have a lot restrictions on the use.

    How to choose a line for a trimmer in terms of composition, thickness and shape?

    When working with a trimmer, the correct choice of fishing line plays a paramount role and determines not only the effectiveness of the technique itself, but also the overall result of the work done. Despite the fact that there is a fairly large selection of various technical features, the main emphasis should be placed on exactly which line to choose for the trimmer. To do this, you need to understand what is the difference between different options for lines and which one is more preferable for a particular type of work.

    If you highlight the main parameters of the fishing line, then usually they are classified according to the following characteristics:

    • Composition
    • Thickness
    • Sectional shape

    Trimmer line composition

    The composition directly affects the life of the line. In most cases, it is made of nylon, since this material has high wear resistance with maximum preservation of working functionality. Also, a clear plus of nylon is that the material is independent of low temperatures.

    Recently, types of woods began to appear, which include aluminum blotches. They further increase the efficiency and service life of such a line.

    Trimmer line thickness

    Also, the thickness of the line must be selected based on the type of motor and power supply. For example, for electrical devices with a power of 1 kW, the best option would be to choose a 2 mm cord, and for motors with a power of 500 W, the thickness of the line should not exceed 1.6 mm.

    Sectional shape of the trimmer line

    The main criteria for selecting the correct cross-sectional shape are the noise level and the type of work. There are quite a number of shapes, including square, star, rectangular, notched shapes, etc. There are also two-component twisted lines that are ideal for cutting dry grass. Such lines are much stronger and more resistant to tears, therefore they have a long service life. Twisted lines are even suitable for cutting shrubs. Their only drawback is the price, which is much higher than for conventional types of cord.

    What is a lawn trimmer?

    It is the fishing line that cuts off excess vegetation due to very fast rotation, therefore its choice directly affects the functionality of the trimmer and how effective it will be in the fight against weeds and grass.

    What and how to choose a line for a trimmer?

    If you are going to tidy up the lawn or remove excess vegetation on the site that has appeared over the season, then you are unlikely to be able to do without a trimmer. Before considering how the choice of line for a trimmer affects its function and efficiency, you need to understand what this device is.

    Tips on how to choose trimmer line for proper use

    The choice of fishing line is the most common question that worries the owners of this device. If the choice of technical characteristics, features and shape is relevant only when buying a trimmer, then the choice of a cord is always important. It is its quality that determines the efficiency and the ability to perform various types of work.

    It should be understood that if even the cheapest fishing line is used for mowing the grass or mowing the lawn, then in the case of cutting and removing bushes and dead wood, you will have to select a special cord.

    To find out how to choose a trimmer line, you need to correctly determine the type of work and the purpose of using the device. By adhering to simple rules, you will not only extend the life of the line itself, but also increase the performance of the device:

    • Select the cord diameter that is appropriate for the specific engine type. Its parameters must fully correspond to the capabilities of the device.
    • Also, when choosing a fishing line, you must take into account the type of vegetation. The thickness of the cord should depend on the complexity of the job. For example, any thin line is suitable for seasonal lawn mowing, while thicker options are better for shrubs and perennial weeds.
    • When working, try to avoid contact of the cord with hard surfaces such as stones, foundations and trees.
    • With proper operation, the line and the reel will last a fairly long period, which will allow you not only to perform the required amount of work, but also significantly save finances.
    • Don’t try to buy the most expensive line options. Sometimes it is completely useless. It is much more important to pay attention to the manufacturer and quality, and not to the special conditions of the cord.

    It is also important to understand how to tuck the line into the trimmer. An improper winding procedure can cause it to malfunction and you will have to purchase another skein. If you do not have such skills and do not know all the features of using the device, then it is better to ask a consultant for all the details when buying a fishing line.

    Some trimmer models only require a certain type of line, so when buying equipment, make sure that it is suitable for the intended tasks. All information can be found in the instructions. Also, always pay attention to the line thickness indicated in the basic trimmer specifications. Using a thicker or thinner cord can cause rapid wear and even damage to the mechanism itself.

    Trimmer line. which one to choose?

    A neat lawn requires a lot of effort and, sadly, time. Fortunately, commercially available tools help solve this problem. One of the most effective is a trimmer that can quickly cut grass on a lawn, near a fence or under a tree. And, like any device, it needs a systematic replacement of components. One of the most important for the trimmer is the line, which rotates and cuts greens like the sharpest knife. But which line is better to use for a trimmer. this is what often worries owners of a useful device.

    How to choose a line for a trimmer. thickness

    Performing the main work, the line, or cord, must meet certain requirements, namely, be strong enough, rigid, but, at the same time, flexible.

    First of all, when making a choice, pay attention to the thickness of the trimmer line. This parameter is usually indicated in the user manual for the device or on the bushing. Usually, a line with a thickness of 1.2 mm to a maximum of 4 mm is used for the trimmer. By the way, with the wrong size of the trimmer line, engine wear is significantly accelerated. If there are no instructions in the instructions for your trimmer, please note that for powerful gasoline devices, woods with a diameter of 2 to 4 mm are chosen. Low power cordless models require up to 2mm line.

    Choosing a trimmer line. material

    The most common material for fishing line is nylon, which is not afraid of engine heat and frequent stress. But if you intend to get rid of coarse weeds, we recommend purchasing a reinforced trimmer line with a reinforced core.

    Types of trimmer line

    Today the market offers various forms of sectioning of the lines, each is selected for specific purposes. Most often, users prefer round fishing line, which is excellent at getting rid of fresh grass. In this case, a line of this shape makes a very strong sound. To remove thick weed stems, it is better to purchase a polygonal type of fishing line. a triangle, square, pentagon, etc. A cruciform line is ideal if your area is covered in dense grass and small shrubs. Tough grass is cut well by a spiral cord.

    As you can see, choosing a line is not difficult. For example, to clean the area from young growth of raspberries for a gasoline trimmer, you will need a 4 mm square-shaped fishing line.

    Manufacturing material

    Various materials can be used:

    • Nylon.
    • Coaxial thread.
    • Nylon with added aluminum, graphite or steel bar.

    The addition of a steel rod or line reinforcement makes it possible to cut not only grass, but also bushes. This line is durable and has a long service life.
