Trimmer Nozzles

Lawn mowing has always been an integral tool in the care of the lawn, both for ordinary people and for public services. over, with its help, you can even harvest hay for pets, cut grass on farm plots or use for weeding potatoes.

Due to the presence of many diverse nozzles, the user has the opportunity to unleash the functional potential of the unit and turn it into a "universal soldier", which will save money, effort and time.

Getting to know the types of lawn mowing nozzles

The basic types include:

• Height cutter;
• Handler of the edges of the lawn;
• Cultivator, etc.

Each of these tools should be introduced a little closer and understand the design features and the specifics of the tasks performed.

Height Cutter: Features

With it, a person can get rid of twigs and branches that grow at a height of three meters. Structural features allow the object to perform such operations, because the nozzle for the lawn mowing cutter consists of a 1.5 meter rod, supplemented by a chain or a tire.

In most cases, the chain width does not exceed 1-3 mm, and a weight of 2.5 kg, comfortable for continuous operation, allows a person to actively operate the unit and not feel pain in the back or shoulders.

It is worth noting that thanks to the nozzle for the lawn mowers, you can get to small branches located at a height of up to 4.5 m.The only difference between the cutter and the delimbers is that the first option works on the principle of a chainsaw, and the second on the principle of a hacksaw.

Lawn Trimmer

In principle, this device is very similar to a standard nozzle lawn mowers, but the main difference lies in a more curved bar. With its help, the operator can reach the most remote and inaccessible places for cutting grass.

In most cases, the specified tool is equipped with a special line feed system. Thanks to this system, the width of the cultivated area can be determined as accurately as possible. The weight of the supplement of such a plan is 2.7 kg.

Cultivator tips

With the help of this nozzle on a lawn mow for cultivation, a person can easily cultivate small areas of land. Additions of a toothed or drum plan are used for loosening soil near trees, the process of digging flower beds and a garden, hilling potatoes, carrots, etc.

Often objects are equipped with several reliable cutting parts. A rod with a diameter of about 25 mm is used with them, contributing to a high level of endurance.
Nozzles also have a setting for the width of the cutters (130-250mm).

Types of cultivator nozzles for trimmer

Today on the market there are 2 types of cultivating nozzles for lawn mowers:

It is worth noting that the milling cutter nozzle on the lawn mowing will not allow the blades to be pressed close to the soil, because the rod springs a lot, and excessive pressure can cause the rod to bend and break. over, experts do not recommend using a cultivator for lawn mowing on clay soil, because it will not be able to penetrate deeper, but will only scratch the surface.

DIY weeding nozzle

It is also encouraging that in modern conditions it is not so difficult to create a nozzle for weeding a lawn mowing machine with your own hands. The main thing is to carefully watch the videos below and follow the advice of people who really managed to design a home-made assistant based on an electric or gasoline unit.

The benefits of weeding with a trimmer head

There are many ways of weeding, both traditional and mechanical. Everyone has positive and negative sides. Experienced gardeners believe that their complex application is required, so the processing efficiency will be of fairly high quality.

Weeding can also be done with lawn mowing. a trimmer driven by burning liquid fuel. This tool is most often used by adherents of organic farming, who tend to believe that it is harmful to cultivate and loosen the soil.

In addition, hollow weeds cannot be removed from the beds, because nutrients taken by the weeds from the soil are also removed from them. According to the principles of organic farming, it is believed that cut weeds should be left in the garden.

They help retain moisture and inhibit the growth of new weeds. In addition, they contribute to the reproduction of microorganisms and worms, which process the remains of weeds into nutrients and contribute to soil fertilization.

Weeding rules

It is necessary to apply a trimmer for weeding when the weeds are not yet too grown and it is easy enough to cut them.

It is important to follow the rules:

Attachment Methods

Attaching nozzles can be done in three ways:

• instead of the gearbox at the bottom of the bar;
• near the engine instead of the rod;
• the way in which the bar is disconnected in the middle.

The braid motor is able to work in different positions and has a high power density, small dimensions and reliable. This allows you to use it using any attachments.

Nozzle options, nozzles for Chinese lawn mowers

Manufacturers offer a wide variety of nozzles for trimmers, just to choose the right one, you need to know the number of teeth on the slots. There may be 7 or 9. Be careful, because nozzles for Chinese lawn mowers may not fit the tools of European manufacturers and vice versa.

Let’s look at a few options.

Drill

A great addition to a gas mowing lawn. A similar gasoline-powered drill has high power, reliability, and durability.

Running wheels

Used with other nozzles if necessary, such as a blower, sweeping brush or roller. Thanks to the wheels, the working body can be raised slightly, this will help reduce its friction against the surface, which will facilitate work, reduce wear, improve quality, and bring pleasure from the work.

Delimbers

Useful when pruning trees at a height of about 4.5 meters. In his work, the principle of a hacksaw is used.

Gardening scissors

They will help to beautifully trim the hedge or curly bushes. There are two models in which different rod lengths are provided. The choice must be made depending on the situation.

Lawn aerator

Designed to saturate the upper layers of the soil with air, by piercing it. This procedure is very necessary for lawns that are more than 5 years old and the root system is quite thickened.

In addition, with its help it is possible to destroy the crust on the beds and lawns after watering, rain, trampling, which helps to increase the breathability of the soil.

Water pump

It will help to supply water for irrigation and domestic needs from a well, any tank, lake or river. It will also help pump out water from the cellar or pool.

Outboard motor

For all types of boats with a transom height of up to 36 centimeters. He is able to provide the boat with a speed of movement of up to 20 kilometers per hour, although with a fair wind and the absence of a headwind.

It can be used to loosen the soil in the beds, in greenhouses, flower beds, flower beds, around shrubs and garden trees.

The use of nozzles for lawn mowers will greatly facilitate and speed up the implementation of various works. Simple enough to maintain, and at a price much cheaper compared to the pendant equipment for the tiller.

This tool is necessary for those who have small plots or are engaged in greenhouse farming. The cultivation procedure allows you to loosen the soil and saturate it with oxygen, which beneficially affects both the development of plants and the quality of the crop.

Particular convenience when using the cultivator is provided by high-quality fastening of the device on the trimmer, quickly rotating mills provide high work efficiency.

The thought-over and qualitatively executed design allows to operate the cultivator for many years. The presence of a protective shield eliminates the possibility of debris entering the operator during operation.

1 Types of nozzles for lawn mowing

When choosing nozzles, it is important to look if this model is suitable for the model of the existing braid or not. Since different companies can produce models with different types of fastening.

All nozzles for lawn mowing are classified depending on the tasks that they perform.

The main types include:

• height cutter;
• blower;
• brush cutter;
• edge trimmer;
• lawn mow with fishing line;
• cultivator.

1.1 Cutter

The nozzle is used for cutting high-growing branches and branches at a height of up to 3 meters. To accomplish this task allows the design of the device. It consists of a straight bar, 1.5 meters high. A small tire and chain are mounted on the bar. Typically, the chain width ranges from 1-3 mm. The weight of the vertical cutter usually does not exceed 2.5 kg. It allows you to comfortably work oblique for a long time.

For some high-cutters, you can choose more efficient tires and extension bars. If components are broken, they can be replaced individually. To make such a nozzle last longer, it is additionally lubricated with oil before work.

1.2 Blower for lawn mowers

This type of additional equipment is used to knock leaves from trees in the autumn, as well as to clean the area from debris and leaves. It works due to a powerful compressor that is able to accelerate air to a speed of 60 m / s. A powerful stream of air can blow away even sand. In an hour, such a nozzle is capable of distilling over 600 cubic meters of air.

Most of the models of this type are made of durable plastic. The only exceptions are a compressor and a shortened bar for fastening. This design allows you to minimize weight. Usually it is from 1.5 to 2.5 kg. The blower can be used either with a swinging bar or using only the lawn mowing motor, depending on the model.

1.3 Brush cutter

This nozzle is designed to work with young and low hedges, or for pruning branches on young fruit trees. The chassis for her is the lawn mowing engine.

As a cutting element, it uses two knives 50 cm long (depending on the models, this indicator may vary). The width of the knives is 2-2.5 cm. During operation, they act like scissors, while the stroke width is from 2 to 4 cm.

The brush cutter can be used in two ways:

• for crowning trees (in this case a direct bar is used);
• for cutting hedges and bushes (used directly).

The weight of the nozzle is 2-2.5 kg. Such scissors can be used not only to cut branches and bushes, but also to cut flower beds. The high speed of the knives greatly simplifies the cutting process. At the transition from the bar to the knives, a protective guard is installed. It prevents the spread of chips when working on the rod and eliminates slipping of the hand on the cutting edge when working without the rod.

1.4 Edge Handler

The edge processor is nearly identical in design to the standard mowing tip. But a more curved bar is used here. This allows you to effectively align the edges of lawns and work with more inaccessible areas. This tool uses a head with a semi-automatic line feed system, which allows you to more accurately adjust the width of the mowed field. In most processors, the width can be set up to 25 cm.

Many models are equipped with special customizable handles that allow you to increase or decrease the width of the grip of the braid. The weight of such a nozzle is on average 2.7 kg.

1.5 We select a successful knife for lawn mowing (video)

2 lawn mowers

This nozzle is standard. It is used for the classical processing of horizontal surfaces: lawns, lawns, meadows. The nozzle uses a block with semi-automatic, automatic or manual feed of fishing line. Coverage varies from 15 to 25 cm. The weight of the nozzle is 2.3 kg. For convenient operation, such a nozzle uses a direct bar and a handle. This design does not allow working in hard-to-reach areas and corners, but it provides high stability and accuracy of horizontal mowing.

A special shield made of durable plastic is installed above the working head. It prevents the spread of mowed vegetation, knots and trash. As the cutting element in most tools of this type, a fishing line and a knife are used. The diameter of the fishing line is 2-2.5 mm. It can be rectangular, triangular or circular. Knives are round toothed and in the shape of a starlet.

The “CLICKER” Docking Node is a split rod, in the middle of which there is a Central Lock. Up to 11 functionally different nozzles manufactured by various companies can be placed on the upper tiller as a lower working nozzle: nozzle. cultivator, edge cutter, air broom, crown cutter, snow blower, pump (pump), turf cutter, reaper, delimbers, etc.

The removable lawn mowers give an important advantage of compactness. it is easy to transport it in the trunk of a car to the cottage and back, even in an electric train or on the trunk of a bicycle, “GORBA”, after all. The “CLICKER” docking unit, where two halves of the braid are connected, gives additional reliability to the drive system, suppressing destructive resonance waves on the drive shaft during operation.

What it is?

The trimmer consists of a cutting element, a rod, an engine and a handle with a control mechanism. It is designed to mow grass in garden areas, as well as to create the perfect lawn. Due to its compactness, the device performs the necessary work in those places where the lawn mower cannot reach. In addition to grass, the trimmer is designed for mowing tree branches and shrubs, as well as creating flower beds. Such equipment is not always used for lawns, as the length of the grass will have different heights.

Specifications

The main technical characteristics of the trimmer are:

• power;
• equipment weight;
• type of power (from the network or using the battery);
• engine location (top or bottom);
• type of cutting element;
• type of rod.

All this must be taken into account, buy a particular device.

How to choose the right one?

Before buying this equipment, you need to understand for what purpose it will be used. For a large plot with a flat lawn, it is better to purchase a light model with a small capacity. If you want to improve the suburban area, then you need to choose a more powerful model.

Cutting tool

To make the cutting process easy, you need to choose the right cutting element. His role is often played by an ordinary trimmer fishing line or knife. When choosing one of the species, it is worth evaluating the type of vegetation. In accordance with these data, a cord is selected, a knife of a certain shape. An important element is the trimmer head. We will consider its varieties below.

Mowing head for trimmer

It is a special assembled coil, inside of which there is a cord. Its dimensions can be varied. A cord 15 meters long should be wound on the inside of the spool. Its ends are pulled out to a certain distance to do the job. When meeting a solid object, it is destroyed. The mowing head for the trimmer can have a different design. It all depends on the type of device. They differ not only in design, but also in the way they are connected. There is also a universal trimmer head, which is suitable for various equipment. This has become possible due to special adapters.

The trimmer head is classified by the method of feeding the fishing line:

1. Tame. In this case, the name speaks for itself, that is, the supply of fishing line occurs mechanically. To make the cord even longer, you must stop the trimmer and manually pull out the ends.
2. Semi-automatic. If you want to replace the cord, you need the trimmer head to touch the ground. At the same time, a special button is pressed and the anchor mechanism opens. Further, the cord lengthens due to centrifugal force. The main feature is that the procedure occurs when the trimmer is on.
3. Automatic. To lengthen the cord, reduce engine speed. Further, when increasing them, the fishing line is fed automatically.

From the foregoing, it follows that the manual mowing head for the trimmer is inconvenient. That is why you should choose an automatic type. However, such a head for the trimmer is not popular among users, since a large amount of fishing line is consumed during operation. Consequently, the optimal view is semi-automatic.

Classification by refueling method

The trimmer head can have several ways of refueling fishing line:

1. Quick charge. The new cord is wound indiscriminately on the coil, that is, it does not need to be removed from the device. The end of the new element is hit into the coil and then wound a certain number of times. When a specific value is reached, the cord is cut off. The head with fishing line for this type of trimmer is manufactured by Shindaiwa and Speed-Freed.
2. Collapsible. Here the name itself speaks for itself. To replace a new cord, it is necessary to remove the coil from the equipment, then unwind the old fishing line and wind a new one.

Design features

It should be noted that the cutting head for the trimmer contains special arrows. They allow you to perform rotational motion of the coil in different directions. If there is a need to wind the line in the direction of rotation of the shaft, it rotates to a specific position. A large amount of coiled cord threatens equipment breakdown. Two arrows are only on imported models. Now on the market are heads with one arrow.

If, after hitting a semi-automatic head, the cord is not wound, then its previous winding is incorrect. That is, after the head for the trimmer was installed, the user did not pull the ends of the fishing line out of the grooves. Another unpleasant moment when the grass is mowed may be the sintering of coil turns. What is this happening for? This happens when the cord meets a solid object. At the same time, it brakes sharply and with the subsequent movement of the fishing line begins to go inside the device. Thus, it gets on the spool and sticks together. Because of this, the employee has to take a break and correct the situation. However, this can be avoided. Before installing the reel, it is necessary to treat the fishing line with a special silicone substance.

For various models of trimmers, a semi-automatic head is used, consisting of two parts. the case and the spool. Both elements contain springs. The second part can be performed in several ways:

• single-section. both parts of the fishing line are wound together;
• two-section. each end is wound on a certain part; this type is the most effective, since the fishing line is not confused and does not sinter.

There is a simple and cheap way to turn a single-section spool into a two-section one. To do this, you need a strong plate. From it you need to cut a circle whose diameter should be equal to the thickness of the spool. In this case, the thickness is taken near the place where the fishing line is wound. This circle moves freely. Further, an incision is made on the ring, put on a spool and connected with glue or tape. As a result, you can wind the line on the desired section. The head for a universal trimmer can have from two to four holes that are located opposite each other. The mowing ends come out of them. In addition to the presented reels, there are heads where a certain size of fishing line is inserted. In this case, the number of whiskers increases to twelve. Many users believe that such a device is quite convenient. However, not all people hold this view. They believe that in this situation, the fishing line will have to spend more. In addition, to replace it, you must stop the workflow. The trimmer head, the caliber of which can be varied, is suitable for cutting grass, shrubs and trees. Before you purchase a trimmer, you must study the area, as well as the features of the equipment. So, we found out what the universal head for the trimmer is for and how to properly fill it.

Weeding potatoes with a trimmer in organic farming

While chemists are developing more and more toxic herbicides, and weeds are adapting to them safely, proponents of organic farming argue that the soil needs to be loosened as little as possible, and traditional weeding is generally a futile task.

Weeds assimilates the beneficial substances with which gardeners fertilize the beds. If weed weeds are removed from the site, the earth will lose a certain amount of trace elements. And if you cut the stems of weed grass under the root (but only until the seeds are formed) and leave to dry on the beds and in the aisles, they will play the role of mulch, attract useful worms and insects, and retain moisture. Of course, after some time new shoots will hatch from the roots. But only one weed will grow in the place of the cut, and if the weed is cut down (it is difficult to completely remove the roots from the ground), then a new plant will emerge from each piece.

With periodic mowing of shoots of weeds, their roots will be exhausted and will die, and there will be nowhere to come from for a new weed, unless the wind will bring seeds. The only exception is the old wheatgrass, whose roots must be carefully weathered, as they are able to pierce potato tubers through.

Another method of organic farming is the sowing of green manure. Rye, barley, oats, phacelia significantly improve the soil structure (and weeds are suppressed at the same time), but they need to be mowed when the potato seedlings reach 15–20 cm in height.

Beds mulch with cut stems of green manure, and the roots die and rot during the season. It is more convenient and quicker to mow weeds or green manure with a trimmer: this is less likely to damage cultivated plants.

Nozzles on the trimmer for weeding potatoes

For cutting weeds and green manure, it is better to use a lawn mowing machine or trimmer, in which the electric motor is located in the upper part: then the device can work in wet grass. In the aisles, they are usually mowed with a trimmer head with fishing line (Fig. 1). It is noted that weeds mowed by fishing line with a circular cross section grow slower than after cutting with a cord with a cross section in the form of an asterisk.

Fig. 1

Sometimes a three-blade knife is used to cut weeds (Fig. 2). But metal knives are worn only on straight-bar trimmers, if it is curved, plastic nozzles are used. The problem is that if the knife in motion stumbles upon a solid object, the trimmer will bounce back or even crack. Models with a curved bar are equipped with plastic knives.

Fig. 2

Fig. 3

The nozzle width, diameter and number of cutters directly depend on the power of the trimmer motor. If you use too large a cultivator, the engine may overheat. Typically, the instructions for the nozzle indicate for which trimmers or lawn mowers it is intended. If the power of the lawn mowers is less than 2.5 liters. s., and there is no cultivator in the kit, it’s dangerous to use the separately purchased nozzle: this will significantly reduce the service life of the equipment.

Manually making a nozzle is not recommended, as it is difficult to choose its width and diameter of the cutters so that the trimmer motor is not damaged. The same rule applies to milling machines as for a mowing knife: a collision with a solid object will break the lawn mowers. Potatoes should not be trimmed with lawn mowing or trimmer on heavy clay soils.

It happens that the Chinese nozzle on the trimmer for weeding potatoes wedges after 10-15 minutes of work. To prevent an accident, experienced gardeners recommend thoroughly treating all rubbing parts of the cultivator with silicone grease before the first use.

Rules for weeding potatoes with a trimmer

1. Before starting work, it is necessary to wear glasses and a respirator: the mills rotate very quickly, creating a cloud of dust and small pieces of grass;
2. Watering should be done when the weeds are still very small and have not had time to take root. Since weeding with a trimmer takes several times less time than manual labor, it is better to process the beds every 7-14 days. When the tops of potato bushes close in rows, weeding is no longer needed;
3. For weeding, it is recommended to choose a sunny morning. Then the weeds uprooted during the heat of the day will fade and turn into mulch;
4. According to the principles of organic farming, it is impossible to deepen cutters more than 0.5-1.5 cm. With this method of processing, the dried crust breaks, and the top layer of soil on the beds is saturated with oxygen and nitrogen, which is very useful for the growth of tubers;
5. Milling cutters cannot be deepened because if you press too hard on the trimmer, the motor will overheat and break;
6. When weeding with a trimmer with a low-power engine, it is recommended to take a break every 10 to 15 minutes to allow the motor to cool;
7. At the end of the season, the nozzle is thoroughly wiped with a disinfectant (a solution of bleach, potassium permanganate or copper sulphate), as potato pathogens can remain on it. If there were cases of diseases on the site, then this operation is performed after each use of the cultivator.

Nozzle repair and milling replacement

A broken mill can be replaced by a self-made one, turning a circle from a sheet of metal, cutting and bending the blades. But the diameter of the new part should not be larger than the diameter of the old. In no case should additional mills be put on the axis of the nozzle.

Design and mounting options

The cultivator nozzle comes in two versions:

• A disc, the cutting organs 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 cultivating unit. Disk nozzles are harder and therefore suitable for processing heavier soils, while toothed ones have a lower dead weight, but are designed for work on lighter soils.

The transmission of torque from the trimmer motor to the cultivator nozzle is carried out using a special shaft, which is arranged in a special rod (it will have to be purchased separately). This node is not interchangeable, and differs in the number of slots on the end of the rod: there may be seven or nine. Therefore, when planning to purchase a cultivator attachment, you need to understand that the Oleo-Mac attachment will not work with the Husqvarna trimmer, as well as vice versa.

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

Features of the nozzle

Any cultivator nozzle for the trimmer significantly increases the weight of the entire device assembly (by at least 5. 6 kg). Therefore, long-term work with such an instrument is not for everyone. It is also necessary to introduce mechanical constraints on the power of the trimmer drive into the calculation. If the engine is designed for a power of no more than 1500 W, then the cultivator can only be cultivated with regularly loosened soil, or limited to hilling of breasts, potato bushes, etc.

Since the drive of gasoline trimmers is located behind the working one, and the drive rod is quite long, vibrations constantly occur during cultivation. Their value is determined by both the length of the rod and the changing load on the disks or mills. These vibrations are transmitted through the shoulder strap to the user’s hands, so it’s not always convenient to control the trimmer’s power button and hold the canopy. Therefore, prolonged soil cultivation using a cultivator nozzle is unsafe for health.

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

The cultivator nozzle “does not like” compacted soil, and when it is first introduced into such soil, the rod drops sharply. Therefore, disk cultivators are equipped with a safety casing (toothed milling cutters are more likely to bend than break, although in this case a low protective shield from the legs would not hurt). The presence of a safety screen affects the visibility of the cultivator.

Is it worth it to do the cultivator nozzle yourself?

The price factor has a significant impact on the choice: whether to purchase such a nozzle, or to make it yourself. High-quality cultivator nozzles for the trimmer can be purchased at a price of 11,000. 20,000 rubles, which justifies itself only with large volumes of work. It is also inappropriate to purchase such a node in cases where the cultivated soil is heavy (for example, chernozem or loam): the cultivator does not raise the soil, but only moves the clods of earth from one place to another, moreover, together with the roots of the weeds or grass pulled out.

The technology for caring for vegetation will change: first, with a nozzle-knife, it is worth walking through the beds, cutting grass, and only then use the cultivator nozzle.

Having decided on the independent manufacture of the cultivator attachment to the trimmer, you should first evaluate the following:

1. The design of the outlet section of the boom: if it is a flexible shaft, then you will have to forget about the cultivator: it will not be able to withstand constantly changing torques in amplitude. The cardan transmission is more functional, and the most successful design is the multi-spline rod, moreover, direct, and not curved.
2. Drive power: if it is less than 1000 watts, the engine will overheat, and cultivation performance will drop sharply.
3. Fuel tank volume: energy consumption will increase significantly, since the cultivator nozzle will have to be made from improvised materials. Therefore, the tank must contain at least 1 liter of fuel.
4. Handle design. Ergonomic experts believe that the most convenient is the T-shaped handle, which provides the most accurate and reliable direction. It is difficult to hold a gas trimmer with a cultivator attachment, which is common in some models with a J-shaped handle.

If the existing trimmer meets the above requirements, and its owner has sufficient experience in performing such work, then it is quite possible to make a disk nozzle with your own hands. As for the gear type nozzles, their independent production is very time-consuming, and will not provide the desired quality.
