What kinds of fishing lines are available?

The most common type of fishing line that fits on almost every type of reel is the round cord. It is a common trimmer line that is suitable for cutting lush grass, but it is much more difficult to mow dead grass, and it certainly cannot cut through bushes.

As a rule, the diameter with which you can mow young grass does not exceed 1.6 mm. The thicker the thread, the rougher the grass it can overcome.

Some lines with sharp objects in star or square shape are better suited to cut dry grass, because of the sharp edges, but they have the disadvantage of higher wear and tear, and are inferior in terms of durability to circular line.

There are lines with improved aerodynamics with characteristic indentations, scales and notches, such a product makes less noise, but it is used only on gasoline mowers, since the output of such a thread from the spool is difficult, it is used most often with discs, in which pieces are inserted. The disadvantage of such a product is its fragility.

Most often in gasoline trimmers with an engine more than 1.5 liters of power.с. cords with a metal cord inside are used. This line is ideal for mowing dry grass and small bushes. The presence of a core, positively affects the durability of this material. The disadvantage of such cord is its price, which is significantly higher than the above listed opponents.

Three-blade plastic blade for electric grass trimmer

In terms of safety, steel cutters are not recommended on electric mowers. they are almost always equipped with plastic blades. The design features of the power tool itself, its technical characteristics make the installation of metal cutting parts dangerous:

According to the rules of safe operation, plastic knives are used only on scythes with a flexible rod. Plastic blades are designed for cutting soft plants (e.g. burdock, nettles), dead wood. Metal blade trimmer is used for mowing thick, tall, rough grass, bushes and shoots of various trees, because its cutting properties and wear resistance are higher than that of its plastic counterparts.

The device, as well as the technical characteristics of benzocoski cause the use of metal heads when working with them:

  • The straight boom increases the distance to the hedge trimmer’s legs;

  • possibility of a smooth set of revolutions.

What is the right way to put a knife on a grass trimmer

The blade on the grass trimmer is not difficult to fit. The manufacturer equips its tools with a special pin to lock the gearbox and a wrench that unscrews the bobbin with fishing line. It is most important to observe safety rules and disassembly sequence when changing cutting elements.

Algorithm of installation of the blade on the grass trimmer is as follows:

  • Remove the blade guard;
  • Lock the drive. To do this two holes must be aligned. in the shaft hub and in the gearbox cup. Once they are aligned insert the pin in the holes;
  • Unscrew clockwise from the hub bobbin with a line or attachment nut that holds the dust cap (if the grass trimmer has not yet been used);
  • Further we establish a cutting knife so that slits on a puck of a hub coincided with notches in aperture of a cutting disk;
  • Install the duster;
  • Tighten the attachment nut (counterclockwise) holding the locking pin;
  • Tighten it with the pipe wrench;
  • Refit the protective shroud.

As you can see, there is nothing difficult. Now you can safely proceed to mowing weeds on the site.

To cut tall, tough grass, or wild growth of fruit trees, a trimmer with a blade is handy. Low-powered electric grass trimmers have plastic blades, while the more powerful gasoline-powered ones have metal blades. If you have previously worked with a fishing line, the mowing head will need to be removed and a knife put in its place. See below for detailed instructions on how to do it.

How to install the saw blade on the grass trimmer

The main working bodies of any grass trimmer are a spool with a fishing line or a special disk (plastic or metal). Both green grass and a fishing line can be mowed with a plastic blade and dry grass, bulrush and even bushes with a metal blade. Is it possible to increase the functionality of the grass trimmer with a circular saw blade??

Mounting a diamond blade

This operation does not differ in appearance from the attachment of a typical disc, except that even more attention, accuracy and careful control is required. Remove the spool with the fishing line, blocking the gear shaft with a special pin or a suitable diameter screwdriver, rotating the fishing line container counterclockwise. Try on the diamond disc to the bottom spline washer and make sure that its seating hole is larger than the diameter of the seating band on the washer. At high revolutions the saw disk could shift, unbalance would occur that would inevitably lead to the tool breakage and even to the injury of the operator or people nearby. We try on the compensating washers one by one and choose the one that fits the width and completely chooses the gap between the saw blade seating place and the centering belt of the lower washer. Install in turn on the gearbox shaft lower washer with an expansion ring, diamond disk, upper washer and protective cup, which is still partially redistributes the clamping force over a larger area. Tighten the complete set on the gearbox shaft using the left-hand threaded nut, first by hand and then with a socket wrench while locking the gearbox shaft from below with a suitable screwdriver. Remove the protective cut plastic tube from the teeth and check once again that the saw blade is firmly mounted on the gearbox shaft. If it turned out to be reliable, the grass trimmer, with the diamond disc installed, is completely ready, both for traditional and not intended for this tool, to work.

Testing in practice

For safety it is necessary to wear a protective helmet with a transparent visor to protect the face, gloves on the hands. Start with small, dry branches, gradually work our way up to larger ones, and finish with 7-8 cm diameter dry and semi-dry tree trunks. You can be sure that the diamond disc grass trimmer works very effectively, reliably and safely. Both cross cuts and bevels are very smooth. They do not show any crumpled or torn wood fibers. Mowing with the diamond disc is also quite comfortable, efficient and productive, no matter how tall, thick or dry the grass is. So, a grass trimmer with a saw blade not only perfectly performs its direct functions (mowing the grass), but also expands the field of application (removing knots and branches from trees, and sawing down non-thick trunks). Attention! You should not be keen on installing large diameter and thickness of the blade on the grass trimmer, as it will cause an increase in stress on the gearbox and engine, and possible premature breakdown. It also reduces the safety of such tools, which should not be allowed in any case.

Blades for brushcutters and their application (blades for brushcutters)

The main material for the production of trimmer blades you like plastic or metal. The use of such expendable parts in almost everything depends on the two characteristics:

For safety reasons, the manufacturer of the domestic is not advised to put on the electronic grass trimmer blades of iron. All brushcutter blades powered by electronic and battery power are made of plastic. Depending on the manufacturer, they will be of solid disc shape, with several blades or in the form of a special mowing head that provides for installation of removable plastic blades.

Flat boom on the gasoline grass trimmer and curved boom on the electronic trimmer

To put an iron blade on the electronic grass trimmer does not allow its design features.

  • Curved boom reduces the distance from the working part of the machine to the hedge trimmer’s legs. For which the design is designed collision blades with a rock or other hard object grass trimmer blades are thrown to their feet.
  • The highest torque, we mentioned above, for which the design of the collision of an iron blade with a rigid object, transmits a huge load on the flexible shaft of the grass trimmer and its engine. Which causes them to break early.
  • The handle of an electric brushcutter in most cases does not have a stop bar. That does not prevent feet injuries.

These features use only plastic blades on trimmers with electronic motors. When colliding with an obstacle, the blades collapse, thus protecting the mower’s legs from possible injuries.

Plastic blades handle overgrown and dry grass perfectly. They can mow nettles and burdock trunks.

The use of iron knives only on gasoline trimmers as justified by design features.

  • The smooth design of the boom extends the distance to the legs, which gives the mower full safety.
  • Comfortable U-shaped and J-shaped handles give you a firm grip. D-handles of the brushcutter are equipped with a limiter that rests against the leg of the mower to prevent the head from coming close to the legs when the cutting blade hits a hard obstacle.
  • Combustion-engine clutch delivers smooth, even speeds to a comfortable level. And when the blade hits a hard surface it can absorb some of the shock.

Thus, gasoline grass trimmers with an iron blade installed is ideal for use on large areas. They successfully cope not only with the highest coarsened grass, weeds, burdocks and nettles, but also bushes and young trees.

The blade shape on the blade of grass trimmer for the grass does not affect the quality of work performed. Their condition does not affect the speed. Triangular, trapezoidal, rectangular forms are our customer is a pre-sale preparation of manufacturers.

If you intend to make hay, it is best to use a brushcutter with more blades. Check carefully the discs with eight teeth or else discs with four big blades and four extra ones. 2 and 3-blade blades will be very chopping grass.

Putting a blade on the grass trimmer is not so difficult. The manufacturer has equipped their tools with a special pin to lock the gearbox and a wrench to unscrew the bobbin with a fishing line. The main thing is to observe safety rules and the sequence of assembly and disassembly when changing cutting parts.

How to choose a disc for grass trimmer

If you mow lawn and garden weeds regularly (at least once a month), the 8-toothed discs are the best choice. For mowing tall grass it is better to choose a tool with 24 or more teeth. the grass is less wound around them. For an electric grass mower of low power, choose plastic blades or light steel paddle tools. It may be worth having two or three different discs for different jobs

For mowing grass it is worth paying attention to tools with holes. these discs are lighter and less stressful for the electric motor of the grass trimmer

It is better to choose discs made of alloyed steel or with a tungsten carbide tipped blade. The best are pobedite discs for trimmers. To mow the lawn and vegetable garden several times a season you can buy even Chinese products. A Chinese disk is inexpensive (400-700) and will last a season or two. Or even more. Branded discs are more durable, but also last longer. И

Sharpening the blade

Regardless of disc quality, over time it gets blunt and begins to cut the grass poorly. If the blades are still relatively new and replacement is not feasible, you can sharpen them with your own hands.

Important! For sharpening, only discs that do not have hardfacing are good. Such parts are discarded and new ones are bought instead.

  • Disassemble the grass trimmer, remove the blades;
  • carefully inspect the disk. if any cracks are found, it is better to replace the part for a new one, as its further use is not safe;
  • bent blades can be carefully bent with a hammer;
  • Given the size of the disk, you need to pick up the file on the metal, this will provide a more convenient work;
  • at an angle of 30 ° equally sharpen all the upper cutting edges of the discs;
  • Assemble the grass trimmer in reverse order.

To sharpen the disc, you can use an emery machine at low speed, setting the wheel for grinding with a medium-sized grain. With such a tool, the process will move much faster. To be on the safe side, you should wear gloves and a face mask or goggles.

So, plastic and metal blades of different shape and number of blades are used for cutting grass on gasoline and electric mowers. They are chosen according to the type of work to be performed and the size of the area to be treated. If blades of a mower get blunt, they can be easily resharpened or reshaped individually. Despite the simple operation, one has to be very careful and beware of safety, because one might injure himself or herself through negligence or damage the machine. For a more detailed description of blade replacement with respect to a particular model of grass trimmer, see the instruction manual or the official website of the manufacturer. For clarity, the general scheme of the process is shown in the video.
