Types of trimmer heads

Mowing head for grass is a cylindrical body, in which is inserted a spool (bobbin) with a thread (cord) tucked into it. This design can be installed on both gasoline and electric trimmers. Heads differ in the way of filling and filing and come in 3 types.

• Automatic. The cord is fed after the user has reduced the engine speed. Although automatic cord feeding is convenient if you do a large amount of work, but such bobbins have one drawback. high consumption of thread.
• Semi-automatic. Using this type of heads does not require the user to perform complex manipulations. The principle is that the cord is extended automatically while the machine is running at full speed. It is enough to slightly knock the grass trimmer head on the ground (this removes the cord lock), and the line for the trimmer thanks to the centrifugal force is pulled out of the bobbin, after which it is cut to the required length by the knife, located on the protective cover.
• Manual. To extend the cord, you need to stop the machine, after which the line for the trimmer is pulled manually.

On the basis of the above, semi-automatic bobbins are the best option. It should also be borne in mind that grass trimmer reels are single string (used only for grass trimming) and double string, which are used for mowing tall grass and small, with thin stems of bushes.

Handle shape

Manufacturers offer 2 handle options:

T-handle is used on models with auto-winding line. Work is done with 2 hands on either side of the boom. This position is convenient for mowing large areas of vegetation. Cutting is carried out as with a grass chopper, from one side to the other. This is not very maneuverable, and works poorly in difficult terrain. Bicycle handlebar can be equipped with control buttons. In domestic types of grass trimmer start buttons are installed on the boom.

Gasoline trimmer with a D-shaped handle is more maneuverable, it is convenient to mow grass in areas with difficult terrain. With this tool, the arms are positioned one above the other. Disadvantage of the handle. it is difficult to hold it, the operation of such a device is more complicated.

Handle in the form of an English letter “J” is the most uncomfortable, so it is rarely found.

How to Wind the line for trimmer on the reel grass trimmer semi-automatic

Lawn trimmers (also known as lawn mowers) are actively used by modern society for the care of lawns and other similar garden objects. The tool is noted for its high efficiency, despite the questionable quality of grass cutting (compared to an ordinary peasant’s scythe. earth and heaven). The main advantage of trimmers (lawnmowers). high productivity with little physical effort of the operator. However, over time, the grass trimmer’s cutting element (the caprone fishing line) wears out or gets damaged, making the grass trimmer a useless tool as a result. Hence, the challenge becomes how to replace the trimmer head and how to replace the trimmer line for the grass trimmer head? Let’s consider this process on the example of lawn mowers manufactured by “Black and Decker” and others.

Grass trimmer line replacement with step-by-step instructions will allow even an inexperienced in such matters lawnmower owner to perform quite complex work.

However, before starting work on replacing the line on the trimmer, it is necessary to ensure the safety of the work. In particular, measures should be taken to protect against careless or spontaneous activation of the lawnmower:

• to exclude spontaneous starting,
• Remove the battery pack (if applicable),
• Place the tool in a comfortable place to work.

Grass trimmer line replacement work is convenient when the lawnmower is lying on the table and the person who does the grass trimmer line replacement has an opportunity to step up to the tool from any side.

Grass trimmer head cover removal

The first stage of disassembly involves removing the grass trimmer head cover. By the example of models trimmer “Black and Decker” and others, to remove the cover is usually enough to apply some force to push out a latch-fixator, which are located on the side of the head.

On some models of lawnmowers, the grass trimmer head is initially disassembled by using the hexagonal key included in the tool kit. The head is usually held by two or three screws, which can be accessed through the side holes of the back decorative cover.

The head cover, where the filament spool is installed, is usually held in place by a latch tab. It is enough to press the latch-lip with some effort and twist the cover, after which the cover is easily removed At the moment of squeezing the latch-lip, you need to slightly rotate and lift the cover of the grass trimmer head to remove the winding drum.

Step two: Extracting the spool (spool) of fishing line

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

The line for the trimmer should be released from the holes by turning the reel. Then carefully remove the spool from the head area. The winding drum of some models is mounted on a spring. This step must be taken into account during the extraction.

Procedure for removing the grass trimmer spool with fishing line from the inner area of the head: 1. head assembly with spool; 2. extraction carefully with a small axial turn; 3. extracted parts The old grass trimmer line is completely removed from the spool. To perform the removal of the old line of the grass trimmer, you need to remove the fishing line from the loops-fixators and pull the free end. This method removes all old winding. The same process is repeated on the second section of the reel. It is recommended to wear gloves when working.

Winding the line

It is not difficult to insert the trimmer line into the grass trimmer. To perform this operation, it is necessary to adhere to a simple algorithm of actions. The first step is to find out how much consumable material is needed. To make its calculations, you need to wind the line for the trimmer on the spool so that the resulting coil would be less than or equal to the diameter of the sides of the structure.

When you have decided on the size of the cord, you need to fold it so that one part is longer than the other by 15 cm. Winding the cord begins from the side that divides the bobbin into 2 parts. Here will be located the attachment, in which you need to insert a thread bent in half.

Now you need to understand in which direction to tuck the line for the trimmer in the grass trimmer. To do this, you need to inspect the bobbin. often a special arrow is indicated on it. If there is no explanatory information, you should find the pointer on the trimmer head, and begin winding in the opposite direction. The further steps can be divided into 4 steps:

• Completing the filament winding. To do this, it is inserted into the side groove on the reel. Its other end is attached to the opposite groove.
• The ends of the fixed line are cut. 7-10 cm of allowance is left over.
• The tucked part is placed in the head of the grass trimmer. This is done by alternately inserting and pulling the thread into the inlets of the design.
• The thread is pulled out of the grooves. At the end of the action is the fixation of the cover of the product with the help of locks.

After completing the last step, the garden tool is ready to work. If after inserting the fishing line into the grass trimmer the device does not work properly, it is recommended to repeat the procedure by changing the thickness or type of cord. Otherwise the product may fail.

After you have chosen a fishing line for the grass trimmer, you need to cut the necessary amount of hair, because all the hair in the broom is not wound in a roll.

Remove the spool and the protective cover from the spool.

They are removed. We secure one end of the mowing line in the gap and gently and evenly wind the trimmer line.

Grass trimmer spool device

Mowing heads for trimmers come in different designs. both simple and complex. The illustration below shows the semi-automatic trimmer head from a Husqvarna brushcutter (Husqvarna) disassembled.

This type of head is found on most STIHL, Patriot, Champion, Bosch, Huter and other electric trimmers. The design of the mowing head is quite simple. It includes the following parts:

• The base of the mowing head;
• button for semi-automatic cord feed;
• bobbin (spool) into which the line for the trimmer is threaded;
• spring;
• eyelets. through them the line for the trimmer comes out;
• trimmer head cover;
• line for the trimmer (cord).

There are also simpler trimmer heads, shown in the following photo.

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

Preparing to change

To make it clear, the mowing head (bobbin) was removed from the brushcutter. To change the line it is not necessary to remove it, everything is done in place. This does not take long.

Disassemble the grass trimmer bobbin. it is held in place by latches. Remove the cover by pushing on the latches. If you can’t do it with your hands, you need a screwdriver.

The bobbin is made up of the following:

The principle of operation is as follows. Pressing the button, the bobbin presses against the spring and comes out of the retaining grooves in the bobbin lid. held in this condition, the spool can be spooled back and forth, thus adjusting the length of the line. When the button is released, the body spring returns the reel to its original locked position.

Reeling the line

Slowly complete disassembly of the bobbin spool without losing any of its parts allows you to move on to the main task. winding the line into the bobbin. Technological features of the bobbin design and number of working eyes determine the sequence of operations.

Reel with one working strand

The simplest variant and uncomplicated sequence of actions:

• The size of the bobbin and the length of the original factory winding determine the recommended line length for winding. 25 m.
• One end of line is inserted through a catching technological hole inside the bobbin.
• The line is wound on the reel in the opposite direction of the bobbin’s rotation of the trimmer’s product. normally an arrow on the inside of the reel shows in which direction the line is wound.
• A small section of line is left free for his output outside. it is fixed in a specialized groove on the inside of the bobbin, designed to hold the winding when assembling the bobbin in working order.
• Let the leftover end of the fishing line pass through the hole on the outside of the spool.
• Bobbin halves are assembled and attached to the trimmer bar.

Reel with two operating tendrils

In this type of bobbin you should determine the number of grooves for winding the line lying on the inner side of the bobbin:

For both cases, take a line for the trimmer with a length of 2-3 m. With single-strand reels the line for the trimmer is pulled through the through hole, its ends (tendrils) are put together and aligned, then reeled in the opposite direction of rotation of the reel on the boom. inside there is usually an arrow indicating the correct winding direction. If there are locking grooves, the ends of the fishing line are threaded into them or held by fingers of free hand, threaded through the through hole of the outer half of the bobbin, the bobbin is closed and attached to the rod of the trimmer product.

The difference in spooling the line in dual reels is that initially a 2-5 meter length of line is folded in half (to define the middle fold), and the loop of the fold is inserted in a special groove between the grooves. Both line tendrils are wound each on their own groove, fixing the tendrils and reel assembly is similar to the above version with one groove.

The first performance of this procedure may seem long and quite time-consuming, but with time and experience, this task will be solved much faster and easier.

The video below will clearly show you how to tuck the line for the trimmer into the grass trimmer reel and properly wind it. this operation is not anything complicated and with some patience is sure to succeed:

Once the cutting thread has worn out as a result of the work, turn off the mower and remove the cover on the mowing head. Remove the fishing line from the groove by pulling it out to the desired length, and reinsert it into the grooves. The amount of material wound on the reel is sufficient for 5-10 cycles depending on the model. When you put the cover back in place, look carefully to see if the grooves where the retainers are inserted are clogged, if they are, clean them thoroughly.

When the line for the trimmer wears out, you need to disassemble the mowing head again, pull out the spool and rewind the working line for the trimmer.

Grass trimmer is the most common unit used for mowing grass and cutting small bushes. This device is distinguished by its simplicity in service, uncomplicated operation during work, and thanks to its low weight even women can cope with it. It is no secret that the quality of grass mowing requires proper selection of cutting tools. As the latter, trimmers use special cutting attachments (discs, knives) or trimmer heads with a fishing line inside. Nozzles and line for the trimmer are an expendable tool, but if the knives can be sharpened, then when the line is worn out, it is necessary to replace it. In this article, we will tell you in maximum detail how to properly replace the fishing line for trimmer.

How to remove the spool and replace the line for the trimmer

Trimmer owners, mainly beginners, get confused, bordering on panic, when it becomes necessary to change the cutting tool or the trimmer line in the reel. Very often when trying to unscrew the mowing head users simply cause it to fail, not realizing that it unscrews in the opposite direction. To prevent this from happening if a tool change is required, it is recommended that you read the step-by-step instructions below.

• Before you tuck the trimmer line into the spool, turn off the brushcutter engine or de-energize the electric grass trimmer to avoid injuries that can occur if the cutting attachment accidentally starts rotating.
• Unscrew the head attached to the gearbox shaft. To do this, the shaft must be secured by aligning the holes on the washer and on the axle, and inserting a metal bar or screwdriver into them.
