Learning how to properly wind the line for the trimmer on the reel of the grass trimmer and lawn mower installation instructions

Owners of private homes know how necessary such a type of tool as a grass trimmer is. It can be petrol and electric, and they differ in the design of power units. To cut the grass in areas where there are rocks, trees and other obstructing objects, a line for the trimmer is used as a cutting device. This consumable wears out during use, so how to wind the grass trimmer spool, we will consider in detail in the material.

A blade is a consumable item made of nylon that serves as a cutting device. It is used to cut the grass, which is achieved by rotating the head of the tool at high speed. 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 brushcutter (2.4 to 3.2 mm).

the more powerful the tool, the thicker the cutting attachment must be. This not only affects the quality of grass mowing, but also the service life of the material. If you wonder how to wind the grass trimmer reel, then it’s time to change the tool. With the advent of spring, this issue is becoming more and more in demand, so it’s time to understand the step-by-step instructions for replacing the fishing line in the grass trimmer reel.

How to replace the trimmer line on the trimmer?

Replacing the grass trimmer fishing line with step-by-step instructions will allow even an inexperienced lawnmower owner in such matters to perform quite a complex job.

However, before you begin work on replacing the fishing line on the trimmer, you need to ensure the safety of the work. In particular, take precautions to prevent the lawnmower from being switched on carelessly or unintentionally:

• do not start the machine unintentionally,
• Remove the battery pack (if used),
• place the machine on a firm, accessible spot.

Grass trimmer line replacement is convenient when the mower is lying on the table and the mower operator has an opportunity to get close to the tool from any side.

Removing the grass trimmer head cover

At the first stage of disassembly the cover of the grass trimmer head is removed. Using the Black and Decker trimmer models and others as an example, to remove the cap it is usually sufficient to apply some pressure to unlatch the locking tab, which is on the side of the head body.

On some models of lawnmowers initially provides for the removal of the grass trimmer head, for which the hexagon wrench included with the tool is used. The head is usually held by two or three screws, which can be accessed through the side holes of the back decorative cover.

The cover of the head, where the filament spool is installed, is usually held in place by a latch tab. All you need to do is to squeeze the locking tab with some effort and twist the cover slightly, after that the cover can be easily taken off

At the moment of squeezing the latch-long tongue, you need to slightly rotate and lift the cover of the grass trimmer head to remove the winding drum.

Step two: Removing the spool (spool) with the line

The next step in the process is to remove the filament reel from the inside of the head. You need to turn the open side of the head to see the trimmer line and spool. On the side of the head to find two recesses (eyelets), through which the line for the trimmer is led out.

Release the trimmer line from the holes by rotating the drum. Then carefully remove the spool from the head area. The filament drum of some models is mounted on a spring. This point must be taken into account during the extraction operation.

Procedure for removing the grass trimmer reel with fishing line from inside the head area: 1. head complete with reel; 2. extracting carefully with a slight axial twist; 3. parts removed

The old trimmer line is completely removed from the spool. To perform the removal of the old grass trimmer line, you need to remove the line from the loops-fixators and pull the free end. Use this method to remove all old spooling. The same process is repeated on the second section of the reel. It is recommended that the technician wear gloves when carrying out the work.

How to replace the trimmer head with the Husqvarna blade?

If you mow hard grass, use a blade instead of a fishing line. The nozzle can look like a solid metal plate with cutting blades or like a disc with plastic blades loosely attached.

• Metal cutting blade: the full-metal blade is better for advanced users, because it is somewhat insecure. We recommend using this attachment only on grass trimmers with a straight boom and on grass trimmers with a twin U-shaped handle.

Plastic blades: grass trimmers with D-bar and curved boom are most often fitted with a disc with plastic blades, which will ensure safety in use (but there are exceptions).

The metal blade is firmly fixed to the carrier washer of the required diameter. It is necessary to cover a disk from above by one or two fixing washers, after that they are screwed on a shaft of a reducer by a nut of the left-hand thread. Pull out the nut carefully to prevent accidental loss.

All about changing lines on a trimmer head

There are many types of heads for different types of lines. The latter is also available in several diameters ranging from 1.0 mm to 3.2 mm. It comes in round (including a special groove for noise reduction), square, twisted and star-shaped shapes.

There is no clear preference, which explains the large variety of shapes and diameters on the market. Round shape is usually stronger, but has a worse cutting ability, in addition, when rotating it makes a characteristic sound. That’s why sometimes an acoustic groove is made on it, however, the use of this line makes sense only on battery trimmers, at machines with a gasoline-powered and mains drive the sound level of the drive itself practically drowns out the sound of the line. A square has a good cutting ability, and even though this trimmer line is less strong than a round line, it is less consumable on average. A square line for a trimmer quite easily cuts the same willow growth up to 1 cm in diameter. A star has the most cutting edges, gives the best cut and is the fastest to use.

The next nuance in the choice is the stiffness. The fact is that in the manufacture of nylon it is added a modifier (often maleic anhydride), which improves its strength and prevents tearing. However, modifiers are not the cheapest component, people try to save on it. Therefore, a seemingly good line for the trimmer, which was left for the winter, suddenly behaves completely differently in the spring. tears, ceases to normally come out of the reel. There is a recommendation to soak the trimmer line in water before working, however, I don’t see much sense in this, maleic anhydride interacts with water, but if it is not enough in nylon, there is nothing to interact with. There is therefore no point in stocking up on fishing line for a long period of time, broken or constantly tearing fishing line for the trimmer, which in addition does not want to come out of the spool itself, can significantly complicate the work.

Putting it to the test

For safety it is necessary to wear a protective helmet with a transparent visor to protect the face, on the hands. gloves. First we try to remove thinner, dry branches, then gradually progress to larger ones, and finish the test by sawing off 7-8 cm dried and semi-dry tree trunks.

Convinced that a diamond disc grass trimmer works quite effectively, safely and reliably. Both cross cuts and bevels are very smooth. No crumpled or torn wood fibers visible. Mowing grass with a diamond disc is also quite comfortable, efficient and productive, regardless of its height, density and degree of dryness. So, a grass trimmer with a circular saw blade not only perfectly performs its direct function (mowing grass), but also expands its range of application (removing knots and branches from trees, and sawing thick trunks). Note! Do not be carried away with the installation of the grass trimmer saw blades of large diameter and thickness, as this will cause an increase in stress on the gearbox and engine, and possible premature failure. It also reduces the working safety of such tools, which should not be allowed under any circumstances.

When to use blades?

When using a brushcutter in the countryside, the most popular attachment is a line for the trimmer. It is economical, economical, compatible with various trimmer heads and operationally safe. The disadvantage of using a fishing line is that it is only useful for cutting undersized brushwood. In other situations, the string is immediately clogged, regardless of whether a gasoline or electric grass trimmer model is used. In addition, vegetation wraps around the spindle, which creates significant resistance to the shaft and leads to its breakage. It can also provoke failure of the piston system in gasoline mowers or burnout of the motor in electric trimmers.

That’s why different attachments are used for mowing tall or tough vegetation. So, for cleaning tall and rough grass, thin shoots of trees and bushes, it is better to install and use a disc. This nozzle is clogged much less often, which contributes to a greater durability of the equipment.

A side note! Due to the fact that the engine of electric trimmers and cordless models is less powerful than on petrol mowers, so the use of discs is more relevant for petrol mowers.

When to use a metal disk on your trimmer instead of a fishing line?

It’s already clear what’s the difference between a metal disc and a fishing line on a grass trimmer. When it is necessary to finish mowing with a fishing line and attach a metal wheel to the trimmer. This question is popular among beginners, because if you keep mowing large and dense grass with a cord, it will wear out quickly. This is due to the fact that the line for the trimmer at high speed begins to break on the thick-stemmed grass, which leads to its damage and, accordingly, rapid wear.

You should use knives on a trimmer when mowing the following vegetation:

• High and coarse grass cover
• Weeds and dead wood
• Young tree shoots up to 7 cm in diameter
• Home to thick-stemmed plants like raspberries, briarberries, currants

The use of knives eliminates the rapid wear and tear of the line, and increases the efficiency and productivity of the grasshopper tool.

Cultivator on a brushcutter. an effective substitute for a shovel and a hoe

For loosening the soil, you can use a shovel or a grass trimmer cultivator attachment. The first tool has only one advantage. the ability to maintain physical shape at all times. Now about the advantages of the lawn trimmer cultivator:

• High site machining speed.
• Efficiency. the cultivator not only loosens the soil, but also shreds it. Immediately after cultivation, the ground is ready for planting different crops.
• Does not reduce the amount of dunnage. Shallow cultivation helps to preserve the fertile layer of soil.
• Lack of physical fatigue. the trimming process is similar to how grass is mowed.

Cultivator from benzotrimmer is used for tillage in the inter-row. fluffing and weed control, so the device is also called mototyapka. When choosing a cultivator attachment under the grass trimmer, it is important to consider the following recommendations:

• quality of the cutting elements. if you choose cheap devices, you are likely to face the fact that during the processing of compacted soil the blades will be deformed;
• Protective cover. a must, the lack of which is unsafe for the operator, as small stones and dust will fly in the operator’s face;
• Sufficient weight of the device. the nozzle must have a mass of at least 5 kg, otherwise it will be thrown upwards from vibrations.

Such a device is used by dacha owners for weeding potatoes, while simultaneously fluffing up the soil and removing weeds. Justifies itself device in the presence of large amounts of work, so it is recommended to evaluate the attachment to the trimmer for grass cultivator on merit. A significant disadvantage of the equipment is a significant load on the shaft and engine, so it is very important to take breaks as often as possible, and use powerful units for work.

How to properly fuel the grass trimmer motor?

Automated garden grass trimmer promises good durability with proper operation, including fueling. It is not allowed to operate the gasoline engine of such a device on pure gasoline. Before refueling, it is necessary to prepare the working mixture of fuel. namely, to mix unleaded gasoline with machine oil.

The working fuel tank included in the set, as a rule, has marks on its body for correct mixture: 1. level of unleaded petrol; 2. levels of machine oil depending on the ratio

Mixing unleaded gasoline with machine oil requires the correct ratio. That’s why many manufacturers of string trimmers and other gasoline trimmers label the working tanks.

The user will only need to fill the mixing tank with fresh unleaded gasoline according to the fuel marker line. Then machine oil is added until the fuel mixture reaches the border of the 40:1 ratio mark (optimal for two-stroke engines).
