Garden trimmer today is a fairly common tool. But without a trimmer line, working with it is impossible. There are quite a few fishing lines. Experts believe the most reliable of them nylon.
Types of trimmer lines.
The twisted thread with notches at work makes the least noise. This property can be considered a big plus. Due to its structure, such a thread also increases the power of the tool itself. You can also purchase a two-piece trimmer line. It consists of an outer and an inner layer. The outer layer is always nylon. This material wears out slowly, is not afraid of loads and temperature changes. Inside there is a metal filling. Due to its rigidity, such material can cut the shrubs well.
The line with protrusions and spikes on the surface has good wear resistance. It is recommended for use with high power trimmers. It can cut thick grass, dry stems, small trees and bushes. For the house, you need to have 1-2 types of consumables to replace consumed constantly. It can be a thread of circular cross-section and fishing line with metal filler.
Selection of consumables.
How to choose a line for lawn mowers? A scaffold is an effective tool of a country lawn-mower. With its help, they mow grass near fences, paths and trees. It must necessarily have the flexibility, rigidity and durability. You can read about the required thickness of the thread in the mower (trimmer) characteristic. Usually used thread with a diameter of 1.2 to 4 mm. But for each device requires a different diameter. A thinner thread (compared to the parameters required by the trimmer manufacturer) significantly increases engine wear and gradually disables it. Thicker. leads to overheating of the engine and to its breakage.
If the battery or electric unit has a motor power of 1 kW, it requires a working thread with a diameter of 2 mm. When the engine power is less than 0.5 kW, the line is taken with a diameter of not more than 1.6 mm. For a trimmer with a gasoline engine, a cutting line with a diameter of 2.4 to 3 mm is needed. Such a cutting tool easily bevels perennial deadwood and thick grass.
For trimmer most often uses a fishing line of circular cross-section. It costs a bit and is quite popular, as fresh grass mows very well. Its disadvantage is a high level of noise emitted during operation.
Manufacturers of mowers recommend using spiral-shaped cutting tools. Also common are:
- square section;
- section in the form of an asterisk;
- rectangular shape.
Greater productivity has fishing lines that have sharp edges and several notches. They cut grass on the lawn more smoothly. Large weeds lend itself well to a cutting tool with notches. The noise level is not very high, and the engine is given extra power if the line is mounted on a powerful trimmer. The working head on the trimmer, on which the fishing line is wound, is installed special.
For mowing dead wood and shrubs, use twisted two-component fishing line for lawn mowers. It has high strength, resistant to tearing. Only suitable for mowers with gasoline engines. But such a cutting tool is quite expensive. For daily work, its application is costly.
The trimmer cutting tool is wound on a special spool. The fishing line is sold in pieces of 10-15 m. It is not recommended to use thin steel wires and stranded cables instead of fishing line. Such nozzles will quickly cause a lawnmower to malfunction, including gasoline or electric motor. For a mower with a gasoline engine, a cutting cord diameter of 3 mm is usually used. You can reduce it, but it is recommended to use a diameter of not more than 2.5 mm.
A thin thread from 1.2 to 1.6 mm is used to trim the lawn. The thread with a thickness of 2 to 2.4 mm cuts young grass well, and a thickness of 3 mm and 3.2 mm is capable of mowing thicker and older grass, dead wood and weeds. Cord 4 mm thick is rarely used.
To extend the life of the cord, you should try to avoid contact of the fishing line with stones, trees, foundations, paving tiles. How to wind the fishing line on the trimmer reel correctly?
Wrong winding will disable the unit. About the rules of winding are written in the instructions to the device. The parameters of the desired cord are also indicated there.
Conclusion on the topic.
Do not put steel wire instead of nylon thread!
It will break, and its pieces will punch leather shoes at high speed. Only reel up to 15 m in length and 2.4 mm to 4 mm in diameter should be wound onto the reel. Ends are brought out.
As they wear, they are set independently. For this, you only need to hit the ground lightly. In other cases, you need to reset the mowing revolutions and then add them again. The line is fed automatically. There are coils and manual feed. To feed the working tool, you need to turn off the engine and pull out the ends of the thread manually.
Winding should be done in the direction indicated by the arrow on the coil body.
