How to replace line in any trimmer

How to replace line in any trimmerSo, first unscrew the nozzle. This should be done by rotating the drum to the right. Here we have in our hands a drum with the remains of an old fishing line. We open it. Most often, the lid is closed with latches that can be opened with a screwdriver, threading it through the holes and slightly pressing. Or you need to squeeze the lock and turn the cover in the direction of the arrow. In this case, the lid itself must be held, since reels with automatic line feed have a spring that, when straightened, can throw out all the inner parts of the drum. Gently pulling out the reel, remove the scraps of fishing line from it.

Now you need to take 5 meters of new line and fold it in half (to find the middle). In the middle part of the reel there is a notch (in some designs. A hole), for which we need to hook our fishing line. There is also an arrow on the spool showing the direction of winding. An important detail. If the reel has two compartments, then one half of the line should be wound in one direction, and the other in the other. When finishing winding, you need to leave 15-20 cm of line free. There are also two notches on the top ring of the coil through which these free ends need to be passed. We dealt with the winding itself.

The last step in the line replacement process is to assemble the drum. First you need to install the spring and washers in their place. Then, holding the reel with one hand, with the other you need to thread the ends of the line into the corresponding holes on the sides of the nozzle. After that, install the coil in its place, tightening the line and being careful not to displace the spring. When all the internal elements of the nozzle take their places, you can close the drum with a lid. You just need to make some effort to ensure that the latches fall into place. Voila! The mowing head is ready for use!When choosing a fishing line for your motor scythe (gasoline or electric), you should dwell on some points, which we will talk about in detail.

Line diameter.The engine power determines which maximum line diameter can be used for a given braid. For example, the manufacturer of an electric trimmer with a power of up to 1 kW recommends using a line of ø2 mm, and at values ​​of about 500 W. Only ø1.5 mm. Also, the manufacturer of any heavy duty curved trimmer recommends using ø2mm line.The gasoline engine is more durable than the electric one, so you can use thicker line there, which means stronger line, which allows you to cut more grass and work longer.On grass cutters with an even bar, you can select the line according to the following simple algorithm: the diameter in millimeters corresponds to the engine volume in tens of cubic centimeters. For example, for a Husqvarna 128R lawn mower with an engine capacity of about 25 cm3, use a line of ø2.5 ± 0.2 mm. For more powerful hedge trimmers with volumes of more than 40 cm3, the diameter of the line is limited only by the geometric dimensions of the outlet openings of the mowing head. No more than 4 mm.So, a thin line (about 1.5 mm) cuts well cultivated lawn grass, and a thick one (for example, 3.0-3.5 mm) successfully destroys weeds and even young shrubs.

Line shape.The simplest and cheapest to manufacture is a round line. However, the requirements of ergonomics and environmental protection limit its use. Due to its physical properties, it creates an unacceptably high noise level (which is comparable to the noise of the engine itself). This is the classic Husqvarna or Oregon RoundLine or Chipmaster.To reduce the noise level produced by the line, it is given a special shape. Made it spiral like Oregon DuoLine Plus (noise reduction by 15 dB) or with special transverse grooves like Husqvarna Whisper (-8 dB).Following the school laws of physics “working” part of the line during the mowing process is only the end surface, not the side surface. However, to increase “sharpness” fishing line, i.E. To increase efficiency, the cross section is changed from round to faceted: star, square or square with teeth. Oregon StarLine, Nylsaw or Flexiblade.For example, according to experts, Oregon Nylsaw line, due to its square profile, by 27% “sharper” its analogue of a circular cross-section, which clearly affects the increase in mowing speed.

Features of the nozzle

Any cultivator attachment for the trimmer significantly increases the weight of the entire device assembly (at least 5. 6 kg). Therefore, not everyone can work with such a tool for a long time. In the calculation, it is also necessary to introduce mechanical limitations on the power of the trimmer drive. If the engine is designed for a power of no more than 1500 W, then the cultivator can only process regularly loosened soil, or limit it to hilling breasts, potato bushes, etc.

Since the drive of the petrol trimmers is located behind the worker, and the drive rod is quite long, vibrations constantly occur during the cultivation process. Their size is determined by both the length of the rod and the changing load on the discs or cutters. These vibrations are transmitted through the shoulder strap to the user’s hands, so it is not always convenient to operate the trimmer button and hold the canopy over a rather capacious unit. Therefore, long-term cultivation of the soil using a cultivator attachment is unsafe for health.

But not everything is so bad: the mobility of the petrol trimmer makes it easy to cultivate the soil between rows, and the absence of wheels on the mounted cultivator does not damage the plants in the beds.

The cultivator attachment “does not like” packed soil, and when it is first introduced into such soil, the bar is thrown back sharply. Therefore, disc cultivators are equipped with a safety guard (tine cutters are more likely to bend than break, although in this case a low protective guard on the side of the legs would not be a problem). The presence of the safety screen impairs the visibility of the cultivator.

Design and mounting options

The cultivator attachment comes in two versions:

• Disc, the cutting bodies of which are a pair of cutting discs;
• Toothed, which is a series of cutters sequentially located on the shaft.

The fundamental difference lies only in the design of the loosening unit. Disc nozzles are stiffer and therefore suitable for working on heavier soils, while toothed nozzles have a lower dead weight, but are designed for work on lighter soil.

The transmission of torque from the trimmer motor to the cultivator attachment is carried out using a special shaft, which is assembled in a special bar (it will have to be purchased separately). This unit is not interchangeable, and differs in the number of splines on the end of the rod: there can be seven or nine of them. Therefore, when considering purchasing a cultivator attachment, you need to understand that an Oleo-Mac attachment will not work with a Husqvarna trimmer, as well as vice versa.

The spline method of attaching discs or cutters to the shaft allows free movement of the cutting bodies, which is ideal for cultivation, since it allows the soil to be loosened with a sufficiently wide grip (up to 200. 250 mm per pass), without requiring a large amplitude of the rod movement. The restrictions on the density of the beds located on the site are also removed. With the lengthening of the beds, the convenience of working with the nozzle in question increases, since the turns will have to be done much less often.

Trimmer cultivator attachment. Should you buy?

By purchasing a gasoline trimmer, the owners of country houses and summer cottages get a powerful enough and autonomous tool for various agricultural work. Over, manufacturers often offer a variety of attachments for them. Brush cutters, deadwood choppers, blowers. Today we will talk in detail about the cultivator attachment for the trimmer.

The cord lengthens spontaneously

There are situations when the trimmer user notices very fast line consumption. At the same time, he never hit the button on the ground to lengthen the line. The reason that the line spontaneously lengthens, being cut on a special knife on the casing of the apparatus, may be no spring in the mowing head. Often novice users of mowers, trying to load the line into the reel, forget to install the pressure spring in the head, or even lose it when opening the lid, and in the future, do not even know about its existence.

Line does not lengthen automatically

If the line does not lengthen when you lightly hit the trimmer button on the ground, then the reasons for this may be the following.

Option 1. A bite has occurred, i.E. Clamping the cord between turns. This problem usually appears if the user has been winding the line on the reel unevenly, with intersecting turns, or winding it with insufficient tension. In the latter case, when the mowing head rotates at high speeds under the influence of centrifugal force, the cord begins to tighten, as a result of which inter-turn clamping of the fishing line is possible. To fix the problem, you will have to disassemble the coil on the trimmer and rewind the cord correctly, that is, in even turns with good tension.

Option 2. Too short ends protrude from the head. The line may not come out when hitting the ground if the ends sticking out of the head are not long enough (short). In this case, the centrifugal force is not enough to stretch the line. Therefore, it is required to stop the unit (turn off the engine or disconnect the trimmer from the mains) and pull the line manually, after pressing the button.

Option 3. The line is soldered inside the mowing head. This causes the coil to lock and not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the coil during prolonged operation of the unit, line hitting hard objects.

1. In the first case, third-party cord can be made of low-quality and low-melting materials that cannot withstand mechanical and temperature stress. Therefore, you should give preference to “branded” lines.
2. But, if you nevertheless purchased a fishing line of unknown quality, and it is often soldered during operation, then you can follow the example of some users who, after threading the cord into a reel, wet it either silicone grease (from a spray can), or mineral oil. This procedure greatly reduces the likelihood of the coils of the fishing line being soldered together.
3. Also, the line can be soldered if it hits a hard object (stone, fence, dry branch, etc.) during mowing. As a result, it stretches slightly and is pulled back into the head at high speed. From friction, the cord heats up, and its turns stick together. The only thing that can be done to eliminate this malfunction is to open the trimmer coil and rewind the line.

Trimmer coil device

Trimmer mowing heads come in a variety of designs, both simple and complex. The picture below shows semi-automatic trimmer head from Husqvarna (Husqvarna) lawn mowers disassembled.

This type of head is present on most lawn mowers and trimmers, such as Stihl (Stihl), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The device of the mowing head is quite simple. It includes the following details:

• Mowing head base;
• Button for semi-automatic cord feeding;
• Bobbin (spool) into which the line is tucked;
• Spring;
• Eyes. Through them the line comes out;
• Trimmer head cover;
• Fishing line (cord).

There are also simpler trim heads shown in the following photo.

All these attachments do not allow you to change the length of the line in a semi-automatic mode (after pressing a button). If the cord breaks, you have to stop the mower and change it manually.

How to remove the spool and replace the line

Trimmer owners, mostly beginners, find themselves in confusion, bordering on panic, when they need to change the cutting tool or line in the reel. Very often, when trying to unscrew the mowing head, users simply render it unusable, not suspecting that it is unscrewing in the opposite direction. To prevent this from happening, if you need to replace the tool, we recommend that you read the step-by-step instructions below.

1. Stop the mowers engine or power off the trimmer before threading the spool to avoid injury from accidental starting rotation of the cutter.
2. Unscrew the nozzle attached to gear shaft. To do this, the shaft must be fixed by aligning the holes on the washer and on the axle, and inserting a metal rod or screwdriver into them.
3. Unscrew the nozzle. Be aware that the thread on the shaft is left-handed. Therefore, turn the trimmer coil to the right, that is, clockwise.
4. Disassemble the mowing head. Most often, the head cover is attached on latches. To remove it, you will need to sink these latches into the case, pressing the edges of the cover. If your trimmer has a semi-automatic mowing head with a button on the bottom, then the disassembly of the attachment should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
5. Cut off the required amount of line. Usually its length is 5 meters. Use a cord of the same diameter as indicated in the instructions for the tool. It is not recommended to exceed the maximum line diameter as this will result in increased engine stress and higher gas mileage.
6. Find the midpoint of the line by folding it in half. You will have a loop.
7. Coils are cut inside special grooves (there may be holes). Insert a loop of line into this slot.
8. Wind the line around the spool by turning it counterclockwise. It is necessary to fill in the cord as evenly as possible, the turns should lie down without overlapping and with good tension. When the winding is complete, leave the free ends of the line about 20 cm long and fix them in the grooves on the sides of the reel.
9. Assemble the mowing head. Before you finally assemble the attachment, be sure to insert spring and washer (if available). Place the spool in the body and thread the ends of the cord through the holes or eyelets.
10. Put on the cover and secure it with the latches.
11. Screw the adapter back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (counter-clockwise).

The cord lengthens spontaneously

There are situations when the trimmer user notices very fast line consumption. At the same time, he never hit the button on the ground to lengthen the line. The reason that the line spontaneously lengthens, being cut on a special knife on the casing of the apparatus, may be no spring in the mowing head. Often novice users of mowers, trying to load the line into the reel, forget to install the pressure spring in the head, or even lose it when opening the lid, and in the future, do not even know about its existence.

Major coil faults

Trimmer users and lawn mowers often face a problem with the semi-automatic mowing head. Coil malfunctions can be as follows:

• The line does not lengthen automatically;
• The cord spontaneously comes out of the reel.
