Why the Trimmer Doesn’t Gain Speed When Mowing

6th July 2020

The unstable operation of the engine causes a desire to identify the reasons why the engine is not gaining momentum, or does not develop sufficient traction, and what causes breakdowns. Imagine, you press the gas pedal, and the engine simply “refuses” to obey the command, and there is no increase in speed.

Or the engine is gaining momentum until a certain point, and then as if something is holding it, but the power does not develop. The task of diagnosing this phenomenon is quite complex, which can be caused by many factors.

One of the common reasons that the engine cannot gain speed and develop enough power is a fuel system malfunction. For all types of engines, regardless of the type of fuel, the fuel system should be checked for operability in the first place, and especially the technical condition of the fuel pump.

It is a faulty fuel pump that makes the engine “starve”, hence its very sluggish work. As for diesel engines, here first of all you need to check the nozzles and plunger pairs of the fuel pump, the malfunction of which leads to the fact that the engine loses its power, and often refuses to start.

Problems with the electrical part

The reasons why the engine is not gaining momentum can also lie in various defects in the fuel system, which lead to the fact that air leaks through the depressurized areas (hose breakdowns, leaking washers), which is extremely detrimental to the operation of the fuel system. It is also worth checking the filters of the fuel system, since dirty and clogged filter elements lead to the fact that the motor power does not develop.

On injection engines, it is necessary to determine how the marks of the gas distribution mechanism are set, since the moment of ignition and injection of the fuel mixture depends on this. You also need to check the timing belt tension, as well as the correctness of its installation, since its improper landing and installation of teeth can also affect the development of the power of the car engine itself.

After checking the fuel system, the engine ignition system follows. The first step is to check the condition of the spark plugs, especially their tips. Pay attention to the candle insulators: if they have brown longitudinal deposits, they must be replaced immediately. If the tips are in tan, then it must be removed and cleaned.

For this purpose You can use coarse sandpaper. Now you need to carefully examine the condition of the distributor and high-voltage wires. Then it will be necessary to make measurements of the wires so that one of them does not possess too much resistance, or so that there is no break in it.

A ballast block may malfunction and may also cause the problem in question. To find it, raise the hood and under the windshield it is easy to see the ribbed block. This is ballast resistance.

Other reasons

Another reason why the engine does not develop power is the suction of air into the cylinders, on the way after the DMRV. Air flow sensor. The fact is that the DMRV provides information to the computer of the machine about how much air has entered the cylinders, and he, in turn, calculates the composition of the fuel mixture. And since the information is unreliable due to excess air, the mixture is also depleted, which leads to reduced engine thrust.

Replacing this clogged air filter, which must be changed once every six months, will also help solve this problem. The fact is that because of the dirt in the filter, it is difficult to supply air masses, as a result of which the engine is barely gaining momentum and develops very little power.

It will not be superfluous to see on the color of the exhaust: if they are black, the check valve may be disrupted.

One of the possible reasons for the failure of the engine and the impossibility of its development of the necessary power can be a banal breakdown of the car computer. If so, then try to unscrew the nozzles, and you will see how large amounts of gas are pouring from the injector. At the same time, such a breakdown can only be eliminated by replacing the on-board computer.

Considering the reasons why the engine is not gaining momentum, let us pay attention to another important aspect. The operation of the catalyst, which is often clogged. To check it, we unscrew the spark plug, then we start the engine and make several sharp presses on the gas pedal.

If there is a sharp increase in power and the engine picks up speed very quickly, then the hitch lies in it. In this case, it will need to be replaced.

Mower Stihl: operating tips

It is inherent in man to ennoble the place in which he spends the lion’s share of his own time. Why the Chinese lawn mower does not develop revolutions? The Stihl FS 55 trimmer of the lawn mower Does not develop revolutions, stalls, goes over the carburetor Thank you for watching. Inhabitants of the cities resort to the services of designers, or try to change something in their own house, acquire the latest furniture, wallpaper, so that when you come home after a difficult day, you can have a moral rest and relax in a suitable environment.

The inhabitants of their own houses, located outside the city, have completely different concerns and requirements. It is necessary to mow bushes, grass, various dead wood in time, to closely monitor the condition of the personal plot and garden.

It is clear that this requires several other means of achieving comfort. And here the new brainchild of engineering comes to the forefront – the lawn mowers of the Stihl office.

Build your house!

About the manufacturer

The history of this German brand begins in 1926. At the initial steps of its own development, the company was engaged in the production and sale of various devices for washing and steam engines. It all began, like many companies, with small production and a narrow focus, which made it possible to focus on the quality of the products.

In the early 30s, the first STIHL chainsaw was released, which was distinguished by its convenience and functionality in those days. The company is developing at a rapid pace, constantly introducing new tools, which gives it the opportunity to enter the international market. Lawn mowers Stihl And already in 1931 the first permanent supply of products to Russia was organized.

Device Stihl

At the moment, the company has launched its activities in more than 160 countries, opening new centers and production offices in Switzerland, China and many other countries. This is fully explainable, because the company’s assortment is impressive: motor drills, gas sprayers, mowers, gas trimmers, chainsaws and almost everything else. I would like to note that Shtil chainsaws are very popular due to their own functionality and applicable cost.

Lawn mowing stalls

When purchasing a lawn mower, you must be prepared for the fact that, like in all other similar tools, breakdowns may also appear in it, which will require repair.

But you should not immediately run to the service center and pay large sums to the craftsmen, convincing you of a severe malfunction in the device.

Lawn mowing stalls at high revs on gas

Perhaps the more common complaint related to gas trimmers is: “lawn mowing stalls. "

Naturally, a rather severe malfunction can also be a prerequisite for this. The two-stroke trimmer engine does not develop revolutions stalls. Lawn mowing fs 130 give the gas stalls. But in most cases the situation is even simpler than it seems at first glance.

To cope with such a problem, first, try to understand its causes without the help of others, because after finding out the reason, it is even easier to fight the problem, and from time to time it will even self-destruct.

In fact, the circumstances, this is when the lawn mower stalls at high speeds, there are quite a few of these circumstances.

Why is the Chinese lawn mowing not developing momentum?

Trimmer not gaining revolutions, very frequent problem and of course not always has the usual solution. In this.

Lawn mowing is not gaining momentum, cause malfunctions and its elimination

1st launch of the newest lawn mowers.He removed the grid from the silencer, began to work.

Another is the presence of malfunctions in the power system.

In this case lawn mowing will stall at idle. Champion trimmer stalls at rpm. Goodluck 4300 Lawn Mower stalls at revs video. The mower stalls when you press the gas. At high speeds, the lawn mower stalls. Out of alignment or improper carburetor adjustment can lead to problems with the power system.

Vibrations that occur during the operation of lawn mowers can lead to misregistration.

Incorrect adjustment of the lawn mowers can be corrected by simply adjusting it in accordance with the requirements specified in the instruction manual.

In addition, sometimes gasoline trimmers can stall due to the valve located in the gas tank cap simply clogging or sticking.

To find out, try using a scythe by loosening the gas tank cap.

If the device works properly in this mode, clean the valve.

Features and best models

The Stihl mower deserves special mention, which is distinguished by its own multifunctionality, reliability and ease of operation. Specialists of the company created many varieties of braids, with different features and applications.

For instance, The range of lawn mowers is designed for mowing grass in large spaces.. For this, a self-propelled wheel system was developed, with which it became possible to care for a large territory without spending a lot of time and effort on it. For the design of shrubs, giving them a kind of artistic image and texture, the lawn mowing is perfect. Lawn Mower Does Not Develop Turnover Cause And if you need a lawn mower for tall grass and uneven areas, then follow this link and get complete information on the selection of this type of equipment.

If you need a more subtle approach to harvesting grass, for example near beds or between trees, then a gas trimmer designed for accuracy and precision of execution will do just fine. The company’s specialists provided all the nuances and possible difficulties when working with braids, so they provided them with nylon strings that prevent mechanical damage to trees.

A special AutoCut trimmer head is also used to ensure the normal functionality of the petrol trimmer string knives. This article will tell you about the prices of gasoline manual lawn mowers; trimmers will also help you make the right purchase that you won’t regret.

Two types of mower data are distinguished: amateur and professional models designed for solving problems of a certain complexity. The first category includes models FS 38, FS 45, FS 55, etc. The features and differences of these tools are in the motor power (from 0.9 to 1.2 hp depending on the configuration) and tank volume (approximately 0, 34 l).

Professional trimmers include Stihl FS 130 and FS 250. Consider the characteristics and properties of several mowers, in particular the FS 38, FS 70 and FS 130.

See the features of the device in the video.

Some tricks of working with a petrol trimmer

The summer season has come, and lawn mowers have habitually rattled out on personal plots. Great tool, powerful and mobile. With the help of a gas trimmer, you can also cut the grass and get rid of dried weeds. However, there are cases that the lawn mowing does not start, works intermittently or without developing full power. There is certainly no time for work! And as they say, you pull the starter handle more than mow.

Difficulties with launching arise not only in experienced lawn mowers, but also in new ones. How to be in this situation? There is only one way out – to heed the advice of experts and take advantage of their practical experience!

FS 38

The model is primarily distinguished by its simplicity and compactness, which is enough for proper care of the adjacent area. The main control keys are located on the handle of the device, which greatly facilitates and speeds up the work.

The price for the Stihl FS 38 is about $ 130.

Engine power – 0.9 hp;
Engine displacement – 27.2 cm3;
Tank volume – 0.33 l;
Engine type – two stroke;
Barbell – straight;
Handle – D-shaped;
Equipment – 2-tooth trimmer blade for grass, glasses for protection, belt;
Weight – 4.1 kg.

Stihl fs 38

This model is one of the most popular on the market! You will find out about all the units that are included in the rating of the best lawn mowers here.

You bought yourself a new gas trimmer and you immediately got into trouble. Very bad start. If you mow a little and then turn it off, then turning it “on hot” is an even bigger problem than “on cold”. What to do with it, I won’t know how to start it right?

The instructions for the lawn mowing plant are as follows:

1. Turn on the ignition.

2. Pump fuel with a silicone button (primer) located at the bottom of the carburetor. It is necessary to do as many clicks (or a little more) as written in the instructions, usually around 8-10.

3. Close the choke.

4. Secure the throttle lever with the stop button at higher speeds.

5. Pull the starter handle 2-3 times. The engine should "grab."

If the engine "grabbed" and stalled, then you need to turn the choke to position 1/2 and try to start again. If the engine starts, then we dump the gas and put the air damper in the "open" position. Getting started.

Carrying out fuel pumping manipulations, one should not be afraid to overfill it. If this happened, and, as they say, “they filled the candle”, then you do not need to unscrew it, just turn the air damper to the “open” position and, while holding full throttle, simultaneously crank the engine with a 2-4 times starter. After that, you can start the engine and get to work.

FS 70

She is more advanced model, characterized by higher power and multitasking. An anti-vibration system is provided, which can significantly reduce the impact of a running engine on the handle.

The time for continuous operation of the lawn mowers is indicated in the trimmer instructions. On average, we mow for 15-20 minutes, after which we muffle the trimmer and let it cool for 3-5 minutes. Also, the duration of continuous operation is provided by weather conditions. In hot weather, when mowing tall grass, weeds, under heavy load, the trimmer overheats faster.

Many problems with lawn mowing are due to improperly prepared fuel mixture. In two-stroke engines, lubrication is done with special oil (not ordinary motor oil!) Mixed with gasoline. If the oil is not mixed with gasoline, then the lawn mower will quickly fail. Oil / gasoline is mixed in the proportion indicated in the trimmer instructions. This is usually 1:40 or 1:50.

The question often arises: the proportion of 1:50 is how much oil and gasoline?

The numbers mean the following: fifty parts of gasoline are taken per part of the oil. Hence: 1000 ml (1 liter of gasoline) is divided by 50, we get 20 ml, i.E. 1:50.

Thus, the composition of the fuel mixture (gasoline / oil) in any proportions can be calculated. To add oil to gasoline not “by eye”, it is advisable to take a 20 ml medical syringe, draw oil into it and “inject” into the tank to prepare the fuel mixture.

Building and Cottage in plain language

What to do if the petrol trimmer is not gaining momentum?

If you have ever purchased a trimmer that works with gasoline, then you probably had to deal with the problem of turning on the trimmer, as well as with such a problem as a gas trimmer does not gain revolutions.

That is why this article was created.

So what to do if the trimmer that has been working for you for several years now suddenly just stops gaining momentum and the motor simply stalls? In this case, you and I should consider a number of problems associated with stopping the motor.

The motor may stall under various circumstances. Why lawn mowing revs. I can’t get it off the ground. And it’s gaining momentum from the floor. Sometimes the cause of incorrect operation of the trimmer running on gas is the clogging of the air filter.

This filter is one of the main reasons why the gas trimmer may stop working.

Different rubbish very often gets into it, dust particles get there, which also clog the filter, so it needs to be cleaned and washed every month, and maybe more often, it all depends on how much power the gas trimmer has, and also how much Often you use this device.

For the period of engine break-in (this is approximately the work of the trimmer on 2-3 tanks), the amount of oil can be increased. For example, mix it with gasoline in a ratio of 30: 1.

A small amount of oil mixed with gasoline leads to increased wear of the piston-cylinder group. An excess of oil in the mixture is not so fatal, but also harmful. Coking of the piston rings, rapid formation of soot in the combustion chamber, and a drop in engine power can occur. In addition, the coke screen of the muffler is coked. Therefore, some users (after the end of the warranty period for the trimmer) recommend dismantling it.

The gasoline used in the lawn mowing machine is AI 92. The brand of gasoline is precisely prescribed in the operating instructions. Do not try to “force” the engine by pouring 95th gasoline into it. This can lead to overheating, unstable operation of the trimmer and breakage.

It is not recommended to leave fuel in the trimmer tank during a long break in work. It is better to finish the working day, having fully worked out the whole mixture. If this is not done, then, because during the night the gas from the engine evaporates, and a thin film of oil remains, the carburetor jets may become clogged. This will cause difficulties the next time you start the engine.

It is also necessary to observe safety precautions when storing fuel. Many pour gasoline into a plastic water bottle. Is it worth it?

FS 130

The model belongs to professional models, so the goals set before it will be slightly higher. It is designed for mowing rough grass, harvesting hard shrubs and young trees.

It provides the latest engine of high power, not emitting a large amount of harmful emissions.

The price for the Stihl FS 130 is about $ 400.

Engine power – 1.9 hp;
Engine displacement – 36.3 cm3;
Tank volume – 0.53 l;
Barbell – straight;
Handle – T-shaped;
Complete set – shoulder strap, two-blade knife;
Diameter of fishing line – 2.4 mm;
Weight – 5.9 kg.

The spread in prices for these models does not mean any difference in quality, first of all, Each Stihl mower is designed for a specific type of work.

It is clear that there is no point in acquiring a more expensive and powerful model if you have a small plot or lawn in front of the house. Simpler models will perfectly cope with this task, but the word “simplicity” is not used in a derogatory form here. More powerful mowers are designed to handle large areas with overgrown and thick surfaces, hence the difference in price. If you are confused in such a variety of tools, then do not be upset, but feel free to click here and we will tell you how to choose a lawn mower for a summer residence.

Characteristics of the model in the video.

However, no matter which model you choose, you must follow certain operating rules recommended by the manufacturer in order to avoid possible breakdowns.

Lawn mowing not develops momentum.One more cause

Chinese lawn mowing Husqvarna analogue reason does not develop turned out to be very simple (see video)

If you have done the filter operations, but the operation of the gas trimmer has remained the same, the gas trimmer is not gaining momentum, what should I do?

Then you should try to remove the filter from the device in order to provide the so-called “relief” of the trimmer. Why the Chinese lawn mowing does not develop momentum, the reason is Husqvarna. Should help.

The next and quite common problem when working with a gas trimmer is that it simply stalls and does not give any signs of life.

In this case, the problem may be as follows:

The last and most common reason for the breakdown of the gas trimmer is that the cable, which is located in the carburetor section, simply slept.

Therefore, make sure in advance that it is well tensioned, but not to the limit, otherwise if the load on the gas trimmer is too heavy, this small cable may crack and then you will definitely have to contact the service center, and then also throw a lot of money down the drain.

In no case should gasoline be stored in plastic containers from under water. When mixing the fuel mixture, a static charge builds up, you can catch a spark.

Therefore, at gas stations they are not allowed to refuel gasoline in plastic cans, only in metal ones. Before pouring gasoline into a metal canister, it is better to put it on the ground, so the static is removed from the body.

But there are situations when simple manipulations with the lawn mowing do not help. The engine still does not start. In this case, we check the power supply and ignition system, guided by the rule "the engine does not work if there is nothing to burn or nothing to set on fire."

Recommendations for use

It is necessary to take temporary breaks in work. Lawn mowing does not develop speed Diagnostics and trimmer mowing stalls at. This is necessary so that the engine of the device does not overheat and does not fail prematurely. Lawn mowing does not develop Dismantling a chainsaw Stihl 180 Stihl FS 55 is not gaining momentum? Yes. For amateur models, a break is provided every 20 minutes for the same time. For professional mowers, interrupt work every 50 minutes, in which case the downtime should be at least 10 minutes.

It is necessary to monitor the condition of the fuel tank. If you do not plan to use the mower for a certain time, it is better to drain the remaining fuel from the tank compartment. This will help prevent damage to engine parts.

Gas trimmer loves cleanliness. It is necessary to monitor the cleanliness of the air filter and fuel. It is better to stand for gasoline purchased at a gas station for 2 days and pass it through the simplest filter – a piece of bike stuff.

We check the electrical equipment as follows:

1. Unscrew the candle, inspect the gap between the electrodes. We set the correct gap between the electrodes in the "grandfather" way. We take a razor blade, scrap it in half and insert a home-made probe between the electrodes. If the blades fit tightly, then the gap is ideal.

2. We put a cap of a high-voltage wire on the candle and lean the candle against the metal surface of the engine. We pull the starter several times. If the spark strikes well at one point, then the gap is adjusted correctly. If not, the spark is weak or “wandering”, then it is necessary to re-adjust the gap between the electrodes.

Also in electrical equipment, an ignition coil may be punched. In this case, the lawn mowing does not start or starts and works intermittently, and then stalls, or does not start up to the “hot” one at all.

You can check the serviceability of the coil in the same way as when checking the spark: unscrew the candle, lean it against the body of the trimmer. If there is no spark when the starter is jerked, or it appears every other time, the coil must be changed.

If everything is in order with the electrical equipment, then we check the carburetor.

Vacuum carburetors are placed on trimmers. When disassembling, cleaning or rinsing, you must be extremely careful – in no case do not disassemble the lower part of the carburetor, where the primer is located. The air filter (it is visible if the protective cover is removed from the carburetor) must be washed with detergents. Best for washing dishes. After drying, put back. We wash the carburetor with clean gasoline and purge all the holes with a pump. The gas line filter is also washed, then everything is dried and collected. Usually, after all the manipulations, the trimmer starts to work.

Thin cable instead of fishing line, is it worth it to put on a lawn mower?

This idea comes to the mind of almost everyone who had to mow 10 acres overgrown with tall grass. At first glance, the idea seems good. The cable is stronger than the fishing line, it does not wear out so much. However, not all so simple.

If you put the cable in place of the fishing line, without the possibility of its release, reliably fixing the two ends of the cable and cutting them off by welding (a drop of molten metal keeps the cable from opening). Such a tool "knocks" the grass at a time. Cutting off the shoot to about a finger thick. Stones are not as afraid as a disc. There is a truth, a problem: pieces of wire rope break off during wear, and these twisted wires remain in place of mowing. If you step on them, you can get hurt.

But the pieces of cable left on the field are half the trouble. The fishing line, breaking off, weakens dynamic impacts on the transmission and engine, the cable does not give such an opportunity. The result is a quick wear of the lawn mowers.

Any braid has a knife on the protective cover that cuts off excess fishing line after winding, and the cable can no longer be cut. If part of the cable breaks off, then the result is an imbalance, increased vibration. Bottom line: the shaft drive bearings are broken.

You also need to remember that a piece of cable unwound by centrifugal force during rotation of the trimmer head flies like a bullet. Imagine what will happen if he gets in the leg or someone in the eye?

The use of a cable, wire, multi-core cable instead of fishing line leads to a quick breakdown of the trimmer. In addition, this is a direct violation of safety precautions!

Experienced users recommend buying a fishing line with an asterisk profile. Compared with a round one, it mows much better; stems with a finger thickness of a fishing line with a diameter of 3 mm cut into a light, and less is consumed.

Reasons and Repair

I want to share my experience in restoring the required power of a trimmer with a gasoline engine.

One day in early June, I began to notice that my trimmer model GT22GES (manufacturer "ECHO") began to lose its former power.

In the process of work when mowing grass, even with a slight increase in load (grass is taller and denser), the speed fell and the work efficiency was no longer the same as it was before.

Before the trimmer did not notice such obstacles at all. With a sharp click on the "trigger" without load, the speed increased slowly, as if reluctantly.

I took the user manual for the trimmer, found in it the section "Faults and their elimination." I chose a suitable fault in the table, which is described something like this: “The engine is not accelerating well or decays.”

Possible causes include contamination of the air filter, fuel filter, clogged fuel tank drainage hole, spark plug, carburetor, clogged cooling system, clogged exhaust channel or muffler.

As it turned out, the list of possible reasons is extensive – where to start?

At first I looked visually at the air filter, drainage hole, air radiator, all this turned out to be in a normal condition.

Then he decided to look from the end of the list, that is, check the exhaust system – the exhaust channel and the muffler.

To do this, removed the spark plug tip, unscrewed 3 screws and removed the plastic muffler protective cover (in the drawing in the Manual under No. 15). Then, unscrewing the two long screws, carefully removed the muffler, so as not to damage the two gaskets that are present there.

Premonition did not deceive me. The exhaust channel of the engine cylinder (through which exhaust gases exit the cylinder) was 30 to 40 percent clogged with soot.

So that was the cause of my trimmer’s frustration!

It looks like the exhaust channel

Carefully, so as not to damage the piston surface and to prevent foreign products (in other words, the very soot) getting into the cylinder, I completely cleaned the exhaust channel of soot, carefully blew the channel with a pump.

I used a knife as a tool (but only at the edge of the canal), and in the depth of the canal I used a wooden and plastic spatula of suitable sizes.

The silencer turned out to be pretty clean both inside and out.

After the assembly, I started the trimmer, warmed it up a bit and tried to mow – the engine worked like new, the power increased noticeably, it didn’t mow the grass, but cut it (3 mm fishing line).

It’s nice that the device began to work perfectly and doubly pleased that he himself was able to find the malfunction and fix it.

It is likely that such a problem can occur in other models of trimmers, because the design for them is approximately the same for all and all trimmers have an exhaust channel and a silencer.

Why do the revs fall on the trimmer

This common problem has a number of different causes. During operation with the device, one may encounter both obvious malfunctions, the signs of which are clearly traceable, and asymptomatic cases. The first option is the simplest from the point of search for the problem. If the trimmer is not gaining momentum and there are no clear signs of damage, then you will need to consistently check the most typical cases of malfunctions, and if a cause is found, eliminate it.

Possible causes of malfunctions in electric braids

When operating the trimmer, on which the electric motor is installed, problems also arise with a set of revolutions. But they are caused by completely different problems, compared to fuel braids. The electric motor does not develop the required rotation speed in such cases:

If the voltage acting in the supply network is lower than the rated value for the electric motor by more than 10%;
In case of malfunctions in the soft start system (if this unit is installed);
When there are problems with the brush assembly;

Electric brush assembly

In case of burning motor windings;
If jamming of the rotating parts occurs.

To eliminate the voltage problem, you need to use a multimeter or tester to check its value in the outlet from which the power of the electric braid is taken. If it is less than the minimum acceptable value, then to increase it, you will need to turn off all electrical appliances or install a stabilizer.

A prerequisite necessary for the normal operation of the trimmer is the use of an extension cord with a cross-section of conductors corresponding to the power of the engine of the braid.

To repair the soft starter, you will need to have the appropriate knowledge of electronics, so it is better to contact a service center. They will determine its maintainability or the need for replacement. You can independently check the button or find the block diagram and try to figure it out.

Soft starter

The brushes can wear out, as a result, the contact will disappear, which leads to motor stops. Brushes are easy to replace. Features of the process are determined by the applicable lawn mowing model. Along the way, you will also need to clean all contact surfaces.

If the windings burn out, if you continue to mow grass or shrubs, the electric motor will quickly burn out. This will be accompanied by the appearance of a burning smell, up to the melting of individual parts. You will need to replace the electric motor.

The wedging of the rotating parts occurs for various reasons. To identify and eliminate them, you will need to sort out the drive unit. There are models in which the number of revolutions is automatically adjusted depending on the load, increasing as it increases – their idle speed decreases.

The video shows an algorithm of actions to identify the most common causes for which the trimmer does not gain the required speed:

Conclusion

The market has a wide selection of trimmers from various manufacturers. They are characterized by common reasons why the momentum is falling. Also, each unit is equipped with an instruction manual. In it, the corresponding section contains the necessary recommendations on this issue regarding the model used.

If in the process of self-troubleshooting a positive result was not achieved, it is better to seek the help of specialists. Also, professionals should be involved in solving the problem in the absence of minimum experience and skills in such a case, so as not to harm. The most difficult unit is the engine. Only experienced craftsmen are allowed to work with it. When the lawn mower is under warranty service, the best option is to contact a service center where they will carry out diagnostics and repair of the equipment.

Small Grass Trimmer For Mowing

20th June 2020

Lush vegetation between houses in a residential quarter or cottage can clutter paths and areas under fences. Unlike a neat lawn, tall grass looks ugly. At enterprises, uncut areas of greenery create an unfavorable impression. To correct this situation, use lawn mowers. But due to their limited maneuverability and high cost, not everyone can afford to buy it, especially in the country or in the public utilities. Now there are their lightweight counterparts – grass trimmers that can do the same job, but are more compact and inexpensive. To correctly choose this garden tool, you need to know the main types of trimmers and what parameters they must meet in order to cope with grass on a specific landscape.

The best trimmer manufacturers. Which company to choose

Good trimmers are produced by companies that have proven themselves in the high-quality manufacture of other electric and gasoline tools.

Those who do not have time to delve into the features of this product can be recommended to purchase a device from any of the companies in the following list:

Echo;
Bosch;
Makita;
Stihl;
Triton.

For those who want to see the advantages and disadvantages of specific models from these brands, a corresponding article has been written with a detailed review. Well, for those who want to understand everything on their own, the parameters and features of this garden tool are given below.

The principle of operation and the device trimmer for grass

The grass trimmer is a garden tool for cutting green vegetation with a soft stem and not thick dead wood. Unlike lawn mowers, the devices have a small weight and are worn by the operator on belts, and do not roll on wheels on the ground. Light weight makes it easy to transport the devices to the place of work and quickly move from site to site.

Using the cutting part of the trimmer, you can:

Maintain a low grass height on the lawn;
Mow it between houses and along paths;
Remove deadwood thickets near the carriageway;
Cut vegetation directly under the fence;
Cultivate the green shores of ponds.

Trimmers have a low cost, unlike lawn mowers, and increased maneuverability makes them more convenient to use. Both residents of the private sector and utilities, as well as enterprises, buy such an instrument in order to take care of the existing territory.

The operation process of the garden tool consists in putting the case on the operator’s body through special belts. The trimmer head is brought to the grass and the button on the handle starts the engine. Torque is transmitted to the bobbin through a rigid shaft in the apparatus tube. The head contains a cutting element that cuts grass stems at high speed.

To prevent impacts on solid objects and sticks flying out in the face, a protective casing is provided, covering 40% of the circumference of the diameter of the action of the cutting part of the tool.

Most modern trimmers have the following device:

1. Motor (electric or gasoline);

2. Fuel tank (in the case of an internal combustion engine);

4. Handle for direction (1-2 pcs);

5. A rigid shaft for transmitting rotation from the motor;

6. A bobbin with a cutting element (fishing line or knife);

7. Protective cover;

8. Belt fastening.

Types of Grass Trimmers

The cutting unit of the trimmer has a removable or non-removable design. Depending on this, the functionality of the models differs. But all trimmers are divided into three categories.

Electric trimmers

This type of tool works from a household network in 220V. The electric motor rotates the shaft and starts the cutting mechanism. To use the device, a power outlet and carrying device must be nearby. This partially hampers the maneuverability and scope of the tool, but allows you to work silently.

Still, such a device has no harmful emissions into the atmosphere. Such models are well suited for summer cottages and private firms with a small territory, where you can get by with one carrying coil.

Advantages:

Lungs;
Make little noise and do not interfere with neighbors;
Inexpensive;
There are powerful models;
No harmful emissions;
Handle height adjustment;
The possibility of setting different knives.

Disadvantages:

Inconvenience from a wire that can be accidentally cut;
Limited area to carry length.

Petrol trimmers

The principle of operation of this type is similar to electric, but the rotation here is provided by an internal combustion engine. To do this, an additional tank with fuel is attached to the rod, as a result of which the device receives a large mass.

With such a tool, you can freely move around the territory and even work where there are no buildings and electricity. There is no need to constantly remember the cord and be careful not to cut it. It is actively used for mowing grass on the sidelines, maintaining the beautiful condition of yards in high-rise areas and on the territory of large enterprises.

Advantages:

Powerful models;
Replacement of knives;
No area restrictions;
High performance;
Robust construction;
Wide area of commercial use.

Disadvantages:

Heavy;
Additional fuel costs;
More noise;
Air emissions.

Cordless Trimmers

A less common type of garden tool is trimmers working with an electric motor, but on battery power. This allows you to cut the grass all the same silently, but not depend on the length of the carry.

Due to limited time use, such models are bought for caring for country houses where there is no electricity or for landscaping kindergartens and similar institutions.

Advantages:

Silent
Setting up different cutting systems;
No area restrictions;
Lungs;
The energy reserve is enough for 30-45 minutes;
Fast charge;
Powerful models are available.

Disadvantages:

Runtime is limited by battery capacity;
Are more expensive than electrical.

Grass trimmer selection options

Understanding the key features of a garden tool, you can choose a model that is well suited to specific tasks and does not cause unexpected problems. Here are the main options for choosing grass trimmers.

Power

The trimmer power rating is indicated in kW and affects performance. The higher this value, the faster the cutting element will rotate and the larger the area will be processed.

1. Garden tools can have a small indicator of 0.25 kW and reach 1.8 kW.

2. For utility services to care for the adjacent territory in the quarters and along the roads along the roadsides, where you have to work all day and mow large volumes of grass, it is advisable to purchase models 0.9-1.8 kW.

3. For giving and caring for a small lawn, an engine with parameters of 0.25-0.7 kW is enough.

Cutting width

The length of the knife and the possibility of maximum extension of the fishing line affect the width of the cut. The last parameter is limited by the dimensions of the protective casing. There are various models whose range can be from 200 to 420 mm.

1. For continuous lawns over a large area, trimmers with a cutting width of 300-420 mm are suitable.

2. 250-270 mm are enough for a summer cottage and care for the blocks of high-rise buildings.

The mass of the device affects the usability and operator fatigue. The weight of the tool varies from 1.5 to 9 kg. Of course, it’s logical to take models lighter for long-term employment, but often this involves remote work from the mains, which requires the most severe gasoline models.

1. If you can connect to the mains, you should buy electrical devices weighing 3-5 kg.

2. For the cottage, an option of 2.5 kg is suitable.

3. If it is impossible to connect to the mains, you should buy gas trimmers with a weight of 7-9 kg.

Revs

Another performance indicator is the cutting speed of the cutting element in one minute.

1. In low-power versions, this parameter is not prescribed because there they are below 7000 per minute.

2. More professional models have an acceleration of 7,500-12,000 rpm.

3. For a summer house or a small business, 6000 rpm is enough.

4. For large volumes of work, 9000-12000 rpm is required.

Diameter of fishing line

This indicator varies from 1.4 to 3.3 mm and indicates the ability of the cutting element to cut through a certain thickness of the stem and branches of the bush.

1. 1.4-2 mm is enough for a country courtyard, which will allow you to remove grass and maintain a neat appearance of lawns.

2. Workers who monitor the condition of the curb, where dense grass often grows, need to purchase 2.4-2.7 mm.

3. To improve the neglected area, a strong fishing line of 3.0-3.3 mm is required, capable of dissecting the stiffened stems and bushes.

Cutting system

Trimmers work by rotating the cutting elements, which can be solid knives (metal, plastic) or soft fishing line (cord).

1. Thick knives are more suitable for a flat open landscape and dense grass with hard stems. The tool will create an even cut. This type is practical for lawn care along businesses and next to a private home.

2. The fishing line is necessary in case of work on hilly terrain and near fences. Beating against solid obstacles will not cause damage, and contact with the ground will not stop the process. But such trimmers do poorly with dense vegetation and get confused.

Type of fastening

To operate the device, it is hung on the operator’s case. For this, one or two belts are provided.

1. The use of a trimmer with a single belt is used to give or ennoble a small area of the company.

2. In the case of a large area, a satchel mount will be required to evenly distribute the load and reduce vibration.

Hold comfort

The shape and number of handles, as well as the balancing of the device, are responsible for this.

1. The main and auxiliary handles are convenient for short use in a garden or a small company. To work all day, it is better to purchase models with a cross frame and two equivalent handles.

2. The position of the engine below the cutting part increases the load on the back and is suitable for mowing only for several hours. If the engine is installed at the top of the rod, this makes it easier to control the tool and is suitable for professional use.

Tank volume and battery capacity

In the case of autonomous fuel trimmers, tank capacity plays an important role. It happens from 0.3 to 1.5 liters. Manufacturers calculate its volume based on the capabilities of the engine to work continuously for a certain amount of time.

1. With a minimum tank, it will be possible to mow for 20 minutes, after which a stop for a break will be required to cool the motor and refuel.

2. It is possible to work with a maximum rate for more than an hour, which is convenient for commercial use in large areas.

For battery models, the battery is measured in amperes / hours. 1st unit A / h is enough for 15 minutes of work. Charging will require three times as much time.

1. For cosmetic care of a small lawn away from the outlet, 2 A / h is enough.

2. To care for the territory of a kindergarten or a small company, 3-4 A / h are required.

What grass trimmer to choose

1. To work on uneven terrain along the fence, you need a device with a fishing line of 2.7 mm thick. For productivity, a cutting width of 250 mm and a speed of 7500 per minute are sufficient. The device will be more convenient to control with two equivalent handles. If the size of the territory allows you to use an extension cord, then it is better to purchase a model with an electric motor.

2. In utilities, on the balance of which there is a large territory with paths and courtyards, as well as road services, you will need a trimmer working on gasoline with a tank of 1.5 liters, 12000 rpm, with a power of 0.9-1.6 kW, 300 mm wide and 3.0 mm thick fishing line.

3. For a large private area or enterprise with green areas, you must buy a garden tool with a 1 kW internal combustion engine, 10,000 rpm, an iron blade or fishing line 2.4 mm and a cut width of 420 mm.

4. In a small courtyard to the cottage, an electric model with a power of 0.25 kW, 6.500 rpm, a fishing line thickness of 1.4-2.0 mm, and a zone coverage of 250 mm across the cut width is sufficient. The mounting method is suitable for one belt with a lower engine.

5. To care for the territory of kindergartens, boarding schools and recreation centers, it is practical to buy battery versions that silently perform their functions over a vast territory. A model with a power of 0.7 kW, a battery capacity of 3 A / h, 7500 rpm and a fishing line of 2.0 mm is suitable.

How much does a grass trimmer cost

1. To work on the hilly terrain and along the fences, the model will cost 3200 – 7000 rubles.

2. Trimmers for 10,000-14,000 rubles are purchased in utilities.

3. To care for the green territory of companies, the tool will cost 15,000-20000 rubles.

4. To give the model start at 1200 rubles.

5. In kindergartens and recreation centers, a battery-powered device will cost 3,000–25,000 rubles.

Since time immemorial, the lawn has been considered an elite element of the site, a privilege of the highest class. However, he will look like a king only with proper care: regular watering, fertilizing and, of course, a weekly haircut. If you do not comply with the last condition on this list, then a beautiful clearing will quickly turn into dense wild growth. Fortunately, mowing grass has long ceased to be a dull duty, forcing the owner of the lawn to get the scythe out of the back room. It was replaced by another tool – a trimmer that works on the principle of the same braid, but mechanized and equipped with a motor. This compact and maneuverable machine can easily cut a small lawn, remove weeds near the wall of the house, cut grass between trees in the garden.

Grass trimmer gives the lawn a well-groomed appearance

Gas or electric trimmer: which is better?

The design of any trimmer provides for the presence of an engine – gasoline or electric. The gasoline-powered internal combustion engine provides complete freedom of movement for the trimmer. It does not connect to an electrical outlet, so you can mow grass anywhere on the site. Lawn mowers, for the most part, have significant power, so they are able to cut stems of hard weed grass, overgrown vines and shrubs. The best trimmer for harvesting hay for pet food is also a scythe with a gasoline engine.

The disadvantages of a gas trimmer include the high cost, the need for regular refueling with gasoline and oil, considerable noise during operation, and the emission of exhaust gases.

Gas trimmer – a standalone tool for large volumes of work

The electric trimmer is devoid of all the disadvantages of lawn mowing. This is a small, compact tool that practically does not make noise during work and does not need to be refueled. However, in some respects it is still inferior to the gas trimmer. First of all, this is low power, which does not allow to cut thick branches of trees.

[include title = "YAN – in the text"]

This parameter of electric trimmers is in the range of 200-1400 watts. Naturally, a 200-watt tool is only suitable for mowing the delicate grass of the lawn. For weed, you need to choose something more powerful. If you are not faced with the task of trimming thick stems, then the best choice is a trimmer with a power of 1000 watts, which can cope with grass and dense thickets of weeds.

Scope of application of a braid limits a cable

Do not forget that the electric trimmer is equipped with a cable that connects to the mains. If it happens that the grass mowing site will be at a great distance from the outlet, then the cable will have to be extended with various electric carriers, which is not very convenient. So it is rational to use a conventional electric trimmer with cable only in the courtyard of the house.

Thinking over the question of how to choose a trimmer with an electric motor, you should know that there is a tool with a lower and upper arrangement of the motor. Despite the fact that the lower position of the engine reduces the cost of the trimmer and increases its maneuverability, with this design there is a risk of water entering the engine, for example, when working on a wet lawn. More optimal is the choice of a tool with an overhead motor that is not afraid of working under any conditions.

Lightweight top engine trimmer

Mowing grass in the area without access to outlets is also possible with an electric trimmer. However, for this, a tool battery must be provided in the tool design, which will allow the low-power engine to work for 20-30 minutes. These trimmers are not used as a regular means of mowing grass on lawns or lawns. They may be needed in extreme cases, for example, in order to trim the edges of the lawn after the lawn mower.

How to choose a cutting tool?

The main function of the trimmer is to mow the grass, so special attention should be paid to the structural part that performs this function. In most electric trimmers, this duty is assigned to a sharp fishing line wound on a reel. During operation, the plastic fishing line rotates at high speed and easily cuts grass and plant stems. As the line is thinning, it needs to be replaced.

[include title = "YAN – in the text"]

In most modern models, this happens in semi-automatic or automatic mode. In the first case, it is enough to press the trimmer head to the ground and the reel unwinds the required amount of fishing line. In automatic mode, everything is even simpler – a new "portion" of fishing line is added each time the engine is turned on.

Reel with fishing line in electric trimmer design – the optimal cutting tool for grass

In powerful gasoline tools, the cutting part is often installed in the form of circular knives that can work for a long time without replacement. At the same time, plastic knives can cut only grass and dry stems, while metal knives can easily cope even with tree branches and shrubs.

Gasoline trimmer with a metal knife will cut any branches

Ergonomics – Bet on convenience

Work with any tool should not turn into hard work, all the details must be carefully thought out for your convenience. To begin with, you should pay attention to the trimmer handle – it can be made in the form of letters D or T. Holding on to the D-shaped handle, it is convenient to mow grass in small areas where good maneuverability is required.

Electric trimmer with a D-shaped handle – a manoeuvrable tool for a small lawn

For large volumes of work, a T-shaped handle is more suitable, in which the movements of the trimmer will be similar to those that are performed when working with an ordinary scythe.

T-handle trimmer easily mow large areas

Vibration absorption is another design feature that is designed to minimize the degree of vibration of those parts of the trimmer that the user is in contact with.

To increase ergonomics, many manufacturers equip a grass trimmer with a telescopic bar, the length of which can be changed, depending on the height of the operator.

How to Install a Mowing Head on a Trimmer

9th June 2020

The trimmer, whether it is gasoline or electric, is the only right solution for mowing grass in hard-to-reach places that cannot be handled by a wheeled lawnmower. As a cutting tool, trimmers use metal knives or a special fishing line, which is tucked into the trimmer coil. But, unfortunately, the trimmer heads during operation over time become unusable. Some malfunctions can be eliminated with your own hands, and some require a complete replacement of the mowing head.

Trimmer Coil Device

Mowing heads for trimmers come in many designs – both simple and complex. The picture below shows semi-automatic trimmer head from the Husqvarna lawn mowers (Husqvarna) disassembled.

How to Install a Mowing Head on a Trimmer

This type of head is present in the configuration of most lawnmowers and trimmers, such as Stihl (Stihl), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The mower head is quite simple. It consists of the following details:

Mowing head base;
Button for semi-automatic cord feeding;
A bobbin (reel) into which the fishing line is refueled;
Spring;
Eyes – through them the fishing line comes out;
Trimmer head cover;
Fishing line (cord).

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

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

Basic coil faults

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

The fishing line does not automatically extend;
The cord spontaneously exits the coil.

The fishing line does not automatically extend

If the line does not lengthen with a light touch of the trimmer coil button on the ground, the reasons for this may be as follows.

Option 1 – a bite occurred, i.E. Clamping cord between turns. This problem usually occurs if the user wound the fishing line on the reel unevenly, with the intersection of turns, or wound 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 drag out, as a result of which it is possible to twist the fishing line. 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 fishing line may not come out when it hits the ground, if its ends protruding from the head are of insufficient length (short). In this case, centrifugal force is not enough to stretch the line. Therefore, it is necessary to stop the unit (turn off the engine or disconnect the trimmer from the mains) and pull out the fishing line manually by first pressing the button.

Option 3 – fishing line soldered inside the mowing head. This causes the coil to stop and not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the coil during continuous operation of the unit, impact of fishing line on solid objects.

In the first case, the cord of third-party manufacturers can be made of low-quality and low-melting materials that do not withstand mechanical and thermal stress. Therefore, preference should be given to “branded” fishing lines.
But, if you nevertheless acquired a fishing line of unknown quality, and it often gets soldered during operation, then you can follow the example of some users who, after refueling the cord into a coil, moisten it either silicone grease (from spray can), or mineral oil. This procedure greatly reduces the likelihood of soldering between each other turns of fishing line.
Also, the fishing line can be soldered if during mowing it hits a solid object (stone, fence, dry branch, etc.). As a result of this, it stretches a little and is pulled back into the head at high speed. The cord heats up due to friction, and its coils stick together. The only thing that can be done to eliminate this malfunction is to open the trimmer coil and rewind the fishing line.

Cord spontaneously lengthens

There are situations when the trimmer user notices very fast consumption of fishing line. However, he never hit a button on the ground to lengthen the fishing line. The reason that the fishing line spontaneously lengthens, cutting off a special knife on the casing of the device, can serve lack of spring in the mowing head. Often, novice users of mowers, trying to charge the fishing line into a reel, forget to install the hold-down spring in the head, or even lose it when the lid is opened, and in the future, they are not even aware of its existence.

How to remove the reel and replace the fishing line

Owners of trimmers, mostly novices, are confused, bordering on panic when it becomes necessary to change the cutting tool or fishing 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, if you need to replace the tool, it is recommended that you read the step-by-step instructions below.

Before putting the fishing line into the reel, turn off the engine of the lawn mowers or de-energize the trimmer to avoid injuries that might occur if the cutting tool is accidentally started to rotate.
Unscrew the nozzle attached to gear shaft. To do this, the shaft must be locked by aligning the holes on the washer and on the axis, and inserting a metal rod or screwdriver into them.
Unscrew the nozzle. You should know that the thread on the shaft is left. Therefore, twist the trimmer coil to the right, that is, clockwise.
Disassemble the mowing head. Most often, the head cover is attached on clips. To remove it, you will need to drown these clips into the body, squeezing the edges of the lid. If your trimmer has a semi-automatic mowing head with a button on the bottom, disassembling the nozzle should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
Cut the required amount of fishing line. Usually its length is 5 meters. Use a cord of the diameter specified in the tool manual. It is not recommended to exceed the maximum diameter of the fishing line, as this will lead to increased engine load and higher gas mileage.
Find the middle of the cord segment, folding it in half. You will get a loop.
Cut through the coils special grooves (there may be holes). Insert a loop from the fishing line into this groove.
Wind the line onto the reel by turning it counterclockwise. It is necessary to refuel the cord as evenly as possible, the turns should lie down without overlapping and with good tension. When the winding is finished, leave the free ends of the fishing line about 20 cm long and fix them in the grooves located on the sides of the reel.
Assemble the mowing head. Before you finally assemble the nozzle, do not forget insert spring and washer (if available). Install the coil in the housing, and thread the ends of the cord through holes or eyes.
Put on the cover and fix it with the latches.
Screw the nozzle back onto the gearbox shaft, also locking it with a screwdriver. Spin the trimmer coil to the left (against the clockwise arrow).

Is it possible to make a coil on a trimmer with your own hands

Take a piece of plywood or textolite and draw a circle on it with a diameter of about 14 cm.
Cut the disc with a jigsaw or hacksaw for metal.
Drill a hole in the center of the disk that matches the diameter of the gearbox shaft. Before installing the disk on the shaft, do not forget to put the washer on it.
On the edges of the disk, you can screw small corners or make 1-2 holes on opposite sides. They will serve to refuel fishing lines in them.
To fix the fishing line, several screws can be screwed into the plywood.

Such a homemade mowing nozzle is mounted on a shaft with a nut. Tighten or unscrew the nut without fixing the shaft will not work. To replace the cord, it will be enough to release the screws, insert a piece of fishing line of the required length and press it again.

Also, a mowing nozzle for attaching fishing line to it can be made from a metal sheet. How to do this, you can understand from the next video.
