Lawn mowing gasoline engine works jerking. The main malfunctions of the motoblocks

The engine of the walk.behind tractor works with jerking causes

If when checking the candle turned out to be wet, but the motor does not start, then detecting the malfunction will be much more difficult:

• may give a failure of the ignition system;
• Due to the depressurization of the compounds, air leaks may appear;
• there may be an unknown air damper in the carburetor;
• Carburetor breakdown.

The ignition system fails is an unpleasant moment, but you should not panic and immediately call a specialist. First you turn out and inspect the spark plug. If you find a dozen on it, clean it with a sandpaper, rinse with gasoline and let it dry completely. Very often after such a procedure, the motor begins to work normally.

If the motor still does not start, and you feel quite qualified, check the size of the gap between the electrodes. The desired value is indicated in the instructions of the manufacturer’s factory, but due to constant vibration during operation, it may change, and the same-based tractor may stall on the go. Adjust the gap to the desired size, bending the side electrode.

With the rest of the ignition system problems, it will not work to understand the move. If you burn out candles or wiring insulators, then they need to replace. You can also close the “stop” button to the mass, and until the closure is eliminated, the engine will not start. Also, the reason that the engine is not started is a violation of contacts in candles or a gap violation between the magnetic shoe and the starter. Finally, the starter itself may be damaged and it will have to be changed.

Another common reason why the motor.block motor “chokes” with a load is stalling. air leaks. If this is due to the depressurization of the carburetor joints, then you first need to tighten the candles and tighten the fasteners, and then check and, if necessary, replace the gaskets. Will “choke” the engine and with the open air damper of the carburetor. To eliminate the problem, it needs to be adjusted, making sure that she goes freely without distortions and jams.

If the one.axine tractor does not gain power normally, it is worth checking its muffler. The fuel combustion products clog the muffler over time, forming a thick layer of carbon on its walls, so it should be cleaned periodically. To do this, the silencer must be removed by plugging the exhaust hole with a clean rag, rinse first in gasoline, and then cleaned with detergents from the carbon fiber, and finally dried with a hairdryer.

Sometimes the same.based tractor stalls during operation and from elementary overheating. If, with a completely open throttle, you click on the gas handle, and the motor, instead of accelerating, loses speed, then this is a clear sign of overheating. The same.based tractor needs to be stopped and let it completely cool, and then run it again.

This is far from the whole list of reasons why your until recently, a completely proper unoic tractor can stall even under a short load. Almost all the nodes of the motoblock during work are subject to significant loads, so small malfunctions and breakdowns are not uncommon. Therefore, having discovered that something is wrong with the walk-behind tractor: extraneous noise, twitching, strong vibration, etc.P immediately turn the engine. And only after the motor cools down, you can start searching and eliminating faults. But this is already a topic for another conversation.

The causes of the malfunctions of the motor block and the ways to eliminate them

Malfunction: one.axic tractor stalls at loads

If the unoic tractor functions normally for several minutes, and then stalls, the reason usually lies in the fuel supply or in problems in the ignition system.

To find out what is the cause of the motoblock malfunction, you must first check how the fuel is supplied:

• Get a candle and inspect. if it is dry, then there is not enough fuel;
• check if the fuel is enough in the gas tank of the walk.behind tractor;
• Make sure that the fuel valve is open. the blocked faucet can be a simple reason that the same.based tractor stalls.

If the problem of the malfunction of the gasoline motoblock in the ignition system, it must be re.adjusted as follows:

• remove the cover that protects the ignition system;
• turn the moss engine of the engine until the contacts in Magneto;
• Using the probe, measure the distance from the anvil to the hammer;
• turn the moss to maximum compressing the piston;
• Once again, turn the moss before the appearance of a knock indicating the work of a overtaking coupling;
• Turn the moss in the other direction so that its label coincides with a mark on the body of the walk.behind tractor;
• set the distance from interrupting contact to a fist of 0.3 mm;
• fix the cam with a screw that is above the element;
• Install the lid in the body of the walk.behind tractor.

If the adjustment is made correctly, the unoic tractor will not stall during operation.

Malfunction: one.axle tractor works with jerks, with interruptions or at reduced power

If the unoic tractor on a gasoline or diesel engine begins to work with interruptions, you need to instantly turn off the unit and start eliminating the malfunction.

Continuing to work with a faulty walk.behind tract means to bring it to more serious breakdowns.

• If the engine of the gasoline walk.behind tract makes return movements, it is necessary to rinse the pump and hoses to supply fuel and replace the fuel with a better;
• When the unoic tractor works with jerks due to incomplete warming up the engine, you need to drown out the motor, let it cool completely, start and warm it up for ten minutes;
• If the engine power has fallen, you need to check and clean the filter system;
• If there is a wear of the ignition magnet, you need to replace the part with a new.

Malfunction: one.axic tractor smokes and stalls, the muffler makes unusual sounds

• With an excess of oil, drain the fuel, rinse the fuel pump and the hose system, pour new fuel;
• check the correctness of the gap between the electrodes;
• If it became obvious that the fuel does not completely burn, disassemble the piston system, rinse and dry the cylinder, correctly configure the carburetor.

Malfunction: one.axic tractor starts up, but stalls quickly

Such a malfunction happens if there are problems with contacts. What to do:

Another reason for the malfunction. the carburetor was polluted, and there is little fuel. Then you need to replace the fuel and reduce the amount of oil.

Malfunction: one.axic tractor stalls when heated

This problem arises due to excessive air entering the carburetor. With such a malfunction, the gas trigger should be squeezed out half. After the motor factory before the start of work, it is necessary to draw well.

If it is not possible to cope with the malfunctions of the garden motoblock, the unoic tractor stalls, the uniform tractor does not start, contact the Alfa-in motor blocks repair workshop using the high-quality repair of gasoline motor blocks using original components that will always be found in our warehouse.

Когда ваш доселе безотказный одноосный трактор начинает барахлить, это очень досадно. It is doubly annoying when this happens in a situation where it is full of work and without a walk.behind tractor, like without hands. It seems to be starting normally, but it is worth it to give him a load, and he immediately sneezes and stalls. What is the reason for this “betrayal”?

The lawn mower stalls

When buying a chainsaw, you should be prepared for the fact that, like all such tools, damage may occur that will require repairs.

But do not immediately run to the service center and pay a lot of money to the masters, convincing them of a serious defect in the device.

The lawn mower stalls at high speeds

Probably, the most common complaint about gasoline trimmers for grass is as follows: “The gasoline lawn mower jams”.

The reason for this, of course, may be a sufficiently serious malfunction. The engine of a two.stroke trimmer for grass does not develop turns and ceases to rotate. The FS 130 gasoline lawn mower gives gas and stops. However, in most cases, the situation is even simpler than it seems at first glance.

What to do with such a misfortune, first try to deal with its causes without the help of others, because, having found the reason, it’s even easier to cope with the trouble, and sometimes it is even self.destructive.

In fact, circumstances, that is, when gasoline burns at high speed, there are many.

Why is a Chinese lawn mower not developing momentum?

Trimmer for grass does not gain speed. a very common malfunction, which, of course, does not always have a regular solution.

The lawn mower is not gaining momentum, the cause of the malfunction and eliminate it

The first launch of new gas stations.Removing the grid from the silencer, began to work.

Another factor is the occurrence of failures in the energy system.

In this case, a braid for grass will stop at idle. At idle, the main secateur stops. GoodLuck 4300 chainsaw stops at idle video. The lawn mower stops when you press the accelerator pedal. The gasoline lawn mower is turned off at high speed. Problems with the power system can be caused by improper carburetor adjustment or incorrectly adjusted carburetor.

Excessive adjustment can be caused by vibration that occurs during the operation of a braid for grass.

However, an incorrectly adjusted chainsaw can be corrected by adjusting it in accordance with the recommendations of the user’s management.

In addition, sometimes gasoline trimmers for grass can be jammed due to the fact that the valve in the lid of the fuel tank just clogged or clogged.

To check this, try starting a trimmer for the grass by unscrewing the fuel tank cover.

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

Some tricks of work with a benzotrimer.

Now is summer, and gasoline engines have become a constant attribute on land plots. Great tool, powerful and mobile. You can mow grass with a gasoline trimmer and cut dry weeds. But sometimes the braid for grass does not start, works with interruptions or does not develop full power. Now, of course, is not the time to work! As they say, this is rather the vibration of the starter handle than the kosba.

Problems with the launch do not only have an old braid for grass, but also in the new. what is the answer? Only one thing remains. listen to expert advice and adopt their practical experience.

Why does a trimmer for grass stall when you press gas, at high and idle speeds, when heated or opened by an air damper

A braid braid with a gasoline drive is a useful thing for owners of personal plots, lawns, and when a trimmer for grass suddenly stalls, the work on cleaning the territory stops from the grass. The device itself is a rather complex mechanism, so there are many different causes of its breakdowns. The most common problems contain instructions for operating. Know the reasons why the trimmer stalls for the grass, it follows to independently effectively perform the repair of the device.

What could break

Malfunctions with a benzocosa associated with the fact that this device is not started, in a certain way are classified by specialists of service services. They stand out malfunctions with the following nodes of the mechanism:

• the engine in which the piston and bearings can be worn out or fail to crack the crankcase;
• the fuel supply system, while it is possible to clog the filter or problems with the carburetor;
• mechanical damage to wires, tubes, hoses;
• The ignition chain.

To correctly determine the knot where the breakdown occurred, it is necessary to pay attention to the circumstances of the trimmer stalls for the grass.

When pressing gas

If the lawn mower stops when pressing the gas, then the reasons may be the following.

• The most common option is a fuss of adjusting the carburetor, which occurs with significant loads on the drive, after a prolonged inaction of the mechanism or when it is used in severe conditions.
• The clogging of the fuel valve, which eliminates it with the message, as a result of which gasoline according to the system begins to flow normally.
• The weakening and hanging of the cable in the carburetor. Also, a tensile of the fuel hose can occur up to its rupture, caused by the action of a significant load.
• Clogging of the saapun (check valve), as a result of which fuel does not enter the tank.

If the problem is associated with the carburetor node, then it can be recognized by the appearance of vibrations of the lawn mower. Когда лопается шланг или растягивается трос — выполняют замену данных комплектующих.

At high speeds

When a braid for grass stalls at high speeds, this is due to the following problems:

• clogging or clutching a valve located on the gas tank lid;
• The carburetor was diluted under the influence of vibrations arising during the operation of the mechanism;
• problems with the circulation of the fuel mixture;
• atmospheric air
• The hose intended for fuel fuel cracked or slightly connected.

The carburetor is regulated by relying on the operational instruction to the trimmer. For configuration, it is often enough to weaken the tightening of its body. If there are problematic issues with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its production, the engine stalls at high speeds.

At idle

At single speeds, the common reasons for stopping a trimmer for grass are as follows:

• reducing the speed of the gearbox when heating it, which is a consequence of the use of inappropriate fuel mixture;
• clogging of the throttle;

If a carburetor is a problem place, then the technique will stop at the “cold” and with a “hot” launch.

Immediately after you started

The unit can stall immediately after the launch, if the carburetor is sipped or incorrectly configured. this causes an uneven supply of fuel. The result is that the device begins to vibrate clearly. To eliminate problems, the carburetor is reconfigured, acting according to the instructions for the mechanism.

The engine also stops when the valve supplies fuel clogs. In such cases, it is enough just to clean it. If the lawn mower at first earned, but then immediately stalled, then possible fuel to the carburetor unit enters some difficulty. The weakening of the valve helps to solve the issue, which provides free circulation of the mixture in the system.

The stop can also be caused by air leaks in the presence of mechanical damage to the hose (holes, cracks) that fuel fuel fuel. In this case, the drive should be added to the drive to quickly drive air bubbles from the system.

When heated

The lawn mower often stops when heated. In this case, it starts, works “with jerks” and gradually stops. This process occurs when gasoline in a carburetor boils or a damper in it is installed by a rotary rather than a disc. In the latter case, the part is changed.

It is found that the trimmer for the grass is heated if the ignition circuit or the coil is damaged. To start working normally, the device is replaced by details.

When opening an air damper

It happens that the unit stalls when opening an air damper, working normally at idle. This is due to the air leaks of the system caused by the presence of fuel hose cracks or problems with the oil seals. The carburetor dosing system can also work malfunctioning, while the lawn mower will stop after the opening of the damper.

All possible reasons that the lawn mower stalls, and the methods of eliminating them are contained in the next video

There are many reasons for stopping Motokos, but the most commonly occur in work related to its carburetor. They can arise in any case. The most problematic option is when there is a serious breakdown, and you will need to purchase new parts or change the lawn mower.

So that the trimmer for the grass works normally for a long time, you should strictly comply with the requirements of the operating instructions. It is necessary to refuel the unit suitable for it in the composition with a fuel mixture, the device should work with a moderate load.

The best models of trimmers according to buyers in 2018

trimmer for grass gasoline. Repair Council

Reasons and repair

I want to share my experience to restore the necessary power of a trimmer for grass with a gasoline engine.

Once in early June, I began to notice that my trimmer for the grass of the GT22GES model (manufacturer “ECHO”) began to lose its former power.

In the process of working with the grass, even with a slight increase in the load (grass higher and thoroughly), the turnover fell and the efficiency of the work was not the same as it was previously.

Previously, a trimmer for the grass did not notice such obstacles at all. With a sharp press on the “gashter” without load, the turnover increased slowly, as if reluctantly.

I took the user guide for a trimmer for the grass, found in it the section “malfunctions and their elimination”. I chose a suitable malfunction in the table, which is described something like this: “The engine is poorly accelerated or fades”.

Among the possible causes are pollution of the air filter, fuel filter, clogging of the drainage opening of the fuel tank, the spark plug, carburetor, clogging of the cooling system, clogging of the exhaust channel or silencer.

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

First, the air filter, a drainage hole, an air radiator looked visually, all this was in normal condition.

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

To do this, he took off the candle tip, unscrewed 3 screws and removed the plastic protective lid of the muffler (in the drawing in the manual under 5). Then unscrewing two long screws, he carefully removed the muffler, so as not to damage the two gaskets that are present there.

The foreboding did not deceive me. The output channel of the engine cylinder (through which exhaust gases emerge from the cylinder) was 30. 40 percent by a pledged.

So this is the reason for the disorder of the work of my trimmer for the grass!

Caution, so as not to damage the piston surface and prevent foreign products from entering the cylinder (in other words, the same carrier), I completely cleaned the exhaust channel from the carrier, carefully blew the channel using the pump.

I used a knife as a tool (but only with the edge of the channel), and in the depths of the channel a wooden and plastic spatula of a suitable size.

The muffler was quite pure and inside and outside.

After the assembly, he started a trimmer for the grass, warmed up a little and tried to mow-the engine earned like new, the power increased noticeably, the grass does not mow, but cuts (fishing line for 3 mm trimmer).

It’s nice that the device began to work excellent and is doubly pleased that he himself was able to find a malfunction and eliminate it.

It is likely that such a problem can arise in other models of trimmers, because their design is approximately similar and all trimmers for grass have a graduation channel and muffler.

Malfunctions of a gasoline lawn mower: the most common problems and their elimination

How does it matter what kind of motorized equipment, the lawn mower bages from time to time and stops working or works incorrectly. At the same time, there is always a certain reason why the equipment works with interruptions, without eliminating its repair will only lead to a stupid embezzlement of money and time

In this case, there is always a certain cause why the technique works with interruptions, without eliminating its repair will only lead to a stupid embezzlement of money and time.

Having understood the device of the lawn mower and the reasons for the breakdown of certain devices, it can almost always be removed without the help of others.

• more frequent defects in gasoline lawn mowers;
• the reasons for these defects;
• diagnostic methods;
• repair and prevention methods.

It shakes strongly

Such a malfunction of a gasoline lawn mower appears in 2 cases:

In both cases, the prerequisite of the shaking is the lack of a knife balance, because when the knife is hit, at least there is not enough, but it is deformed, and with incorrect sharpening, the metal on both sides is removed unevenly.

As a result of this, a lever appears, the length or mass of the shoulders of which is at least insignificant, but differs. This leads to the fact that the shaft of the motor will always pull right behind the more languid or long.length shoulder of the lever, and thanks to its rotation, such an effort will also move in a circle.

To establish the cause, you need to prepare and install a gasoline lawn mower to the position for replacing the knife (these operations are carefully described in the operating annotation). Then the knife is painstakingly examined in search of damage, but if the external examination did not give anything, then it is removed and balanced.

With independent balancing, the knife is put on the rod and look at which sides will go down, for a more clear balancing, you can slightly twist the knife on this impromptu shaft.

Having determined the more languid side, it is gradually dragged by a raster with a manually or on a sharpener, checking the balance all the time, while the metal is removed only from the side of the blade, maintaining the initial angle of sharpening. In the same way, the knife is sharpened in home criteria, at first the tip of the blade, then balancing it.

On certain models of gasoline lawners, a shaking prerequisite can be a broken adapter between the motor shaft and a knife that protects the shaft from damage in a collision.

To diagnose such a malfunction, you need to install the device in a position for replacing a knife, then shake the knife in different directions and test it to scroll it.

If he even sways or turns a little, the adapter must be changed. because he completed his task, protect the shaft during a sharp stop of a knife, which can no longer firmly fix the knife. Its substitution is also described in the annotation of operation.

Poorly cut the grass

If after mowing the grass looks cloud, then cause there is always one. a dumb knife that needs to either be flooded or changed.

The incorrectly sharpened knife is rapidly stupid and loses balancing, which can lead not only to the emergence of vibration, and to the rejection of the motor bearings of the motor. If the knife can be sharpened, then do it because it is described in the last section.

The reasons for the weak.speed trimmer for grass

If users complain to the trimmer for grass, which does not gain momentum, this means that it works normally on idle, and when pressing gas does not develop the necessary power. This can happen as a result of a long downtime of the apparatus without activity. These problems are typical for gasoline devices, including the Husqvarna 128R, STIHL FS 38 and Hitachi different modifications.

Working with a trimmer, you need to monitor its behavior all the time. a drop in revolutions and unusual noises signal the malfunctions in the aggregate. Sometimes you give gas, and the trimmer for the grass swims. In such cases, the work should immediately be suspended, let the mechanism cool and start searching for possible problems. They can be of a different nature of both the technological plan and external factors related to the conditions and features of the operation of the device.

External factors

Several factors that are not related to its breakdown affect the reduction of revolutions:

• filter pollution due to the hit of particles of dirt and dust in it;
• use of poor.quality fuel;
• incorrectly prepared mixture (relevant for trimmers with two.stroke gasoline engines);
• pollution of the muffle of muffler particles of vegetation, soil elements and other objects.

In this case, in the second and third cases, the formation of a soil in the combustion chamber is formed, and the elements of the carburetor are clogged.

technical issues

The technical problems of the lawn mower mainly occur in the fuel and ignition system. You can cope with them yourself.

• Когда ручная косилка не заводится или глохнет, проблема может быть связана со свечой. The dark cargo speaks of poor carburetor adjustment and low gasoline quality.
• The reason for the incorrect operation of the trimmer for the grass may be clogged fuel hose. Filters are also often clogged.
• Another internal problem. the muffler is covered with soot. From this, the turnover of the grass for the grass falls strongly. Output. you need to clean the muffler.

Why does a trimmer for grass stall when you press gas, at high and idle speeds, when heated or opened by an air damper

Repair of the lawn mower

Faced a partially faulty electric gas mowing Al-ko. When turned on, it worked properly, but as soon as a small bump or unevenness came across, it turned off. When re.turning on, the situation was repeated again. At the same time, the longer the lawn mower worked, the more often it turned off.

On examination, it turned out that to increase the safety of operation of the lawn mower, the circuit breaker was made with protection. To turn on the lawn mower, first you need to press the button and then pull the red lever to the metal pipe-handle and hold it during the mowing process of the grass. Judging by all signs, the malfunction was in the switch node.

Since it is difficult to high.quality repairs in the field, I decided to remove the switch unit and understand the reason for unstable work in the workshop. To do this, it was enough to unscrew two self.tapping screws.

From the circuit breaker’s unit was a cable into the gas mowing housing. An attempt to disassemble the circuit breaker unit to disconnect it from the cable was unsuccessful. The head of the screw had a trihedral slot, which provides only for its tightening. It is impossible to unscrew such a standard screwdriver.

Dismantling the lawn mower

I had to unscrew the lid on the housing of the lawn mower, under which the cable went on the side. But here, too, was awaiting difficulty. The screws of the screws were hidden in the depths of the secret holes and were tightly clogged with grass with the ground. After cleaning the heads of garbage, it became clear that they were designed for a cross screwdriver, but all attempts to unscrew them with such a screwdriver were unsuccessful.

Managed to display them with a screwdriver with a flat sting. It turned out that the center of the Schlitsov was raised and the cross screwdriver did not fully enter the engagement. Another protection against independent disassembly.

After removing the lid, it was found that the cable was recorded by four self.tapping screws of the same size, but with normal slots. Therefore, to exclude difficulties in unscrewing the lid in the future, rusty screws that previously hold the lid were twisted into cable clamps.

After many years of work, a lot of mowed grass accumulated inside the lawn mower, which wrapped the connectors and the start.up capacitor. I had to remove it to continue the repair.

After cleaning the lawn mower, access appeared to the connectors. To dismember the connector coming from the switch, it was enough to take the latch with a flat screwdriver to the side.

In the lawn mower, an asynchronous single.phase electric motor was installed, not having a collector and brushes. Thanks to this, there is no need for regular maintenance of the lawn mower. This lawn mower for ten years refused for the first time.

And then another malfunction was discovered, which did not show itself. When checking the freedom of rotation of the engine rotor by influencing the impeller, it turned out that it was not fixed on the shaft and easily starred.

The surface of the engine’s holes on the engine shaft was smooth. It seems that when spent, the knives fell on the branches, stones and, as a result of repeated jerks, the plastic of the impeller was cut off.

For reliable fastening of the impeller, the engine shaft was wound in one layer of a strip of a medical patch on a fabric base with a protrusion for the end of the shaft for 5 mm. Then, through a wooden gasket by blowing a hammer, the impeller is planted on the shaft. The landing was quite durable.

The breakdown of the circuit breaker unit in this case turned out to be good, since due to wear of the impeller mounting, the engine could burn out due to overheating and I would have to buy a new lawn mower.

The breakdown of the circuit breaker unit in this case turned out to be good, since due to wear of the impeller mounting, the engine could burn out due to overheating and I would have to buy a new lawn mower.

Polish rotary mowing disassembly

Rotor Polish mower: the best models and operating tips

Agricultural equipment has long and firmly entered the familiar life of a rural resident

over, it does not matter whether he is engaged in agriculture at a professional level or not. One way or another, everyone is faced with the need to acquire such a technique, because the farmer’s work is very difficult, which is not always able to cope with his own hands

And if you take into account the coarse of large agricults and farms, then there you just can not do without such technology. Therefore, in recent decades there has been an extraordinary demand for various sowing, tractor, soil and other types of equipment.

Various mowers for a tractor gained considerable popularity, allowing to process large areas, mating grass and various crops. Large agricultural companies promptly reacted to such a tendency, expanding the vector of their development to the production of such units and devices.

At the moment, three categories of main manufacturers of rotary mowers for tractors note: European companies, domestic manufacturers and Chinese equipment. Each category has its pros and cons, for example, Chinese manufacturers provide their equipment at very favorable prices, significantly different from European.

However, the low price is perhaps the only advantage of such models. If you need a really high.quality product, then your choice should fall either by equipment that is characterized by the optimal combination of price and quality, or for European models. Of course, the price of them will be slightly higher, but for quality, as we know, we always have to pay more. About a wise approach to the question of how to choose a lawn mower we will tell you here.

Modern production technologies and advanced technological enterprises located in Europe allows this quality to demonstrate to fully. One of the most famous manufacturers, popular among farmers, is the Polish. engaged in the production of various agricultural machinery, including rotary mowers for tractors. You can find out about a segmented mower for a tractor, which is an excellent alternative to Wirax mowers in this article.

At high speeds

When the braid is delayed at high speed, this is due to the following problems:

• Clogging or clutching the valve located on the gas tank cover;
• The carburetor is not leveled under the influence of vibrations arising during the operation of the mechanism;
• Problems with the circulation of the fuel mixture;
• Air flow;
• The fuel injection hose cracked or weakened.

Carburetor settings, on the basis of instructions for operating a trimmer for grass. To adapt, it is often enough to loosen the lift of the body. If there are problems with the circulation of the fuel mixture, it can gradually get into the carburetor. After its development, the engine stops at high speed.

The engine of the walk.behind tractor is bad to start hot

The question of why the engine of the walk.behind tractor stalls when heated is quite simple to solve. The whole essence of the problem lies in the overabundance of the air supplied to the carburetor of the walk.behind tractor. Part of it is mixed with a mixture of gasoline and engine oil, and the second part cools the carburetor. As a result of this, the temperature of the carburetor becomes much lower than the temperature of the aggregate motor. Such a problem is observed only in the process of working motoblock. When its engine is jamming, the carburetor, on the contrary, lends itself to heating from the hot walls of the motor.

During heating the carburetor of the motoblock, the remnants of fuel begin to actively evaporate, filling all the void in the device, including the air filter and the inlet collector. This leads to a complete disappearance of the fuel, which is why the unoic tractor does not start with a heated motor.

To fix this problem, it is necessary to act in a certain algorithm at the start of the walk.in on the hot unit in a certain algorithm. Your main task is to achieve the combination of the mixture so that the motor can start. This will need:

• In the process of starting the hot motor, squeeze half the gas trigger;
• Do not try to press the gas trigger over and over again, otherwise you will only aggravate the situation, since during the frequent pressing of the gas trigger, the fuel pump will supply new portions of fuel to the carburetor, which will lead to pouring the motor;
• After several attempts to launch with a half.pressed gas trigger, you will start a motor block engine, after which you will need to calculate 2-3 times and continue to work.

This procedure will eliminate the increased load on the hot motor, so the main details and mechanisms of the walk.behind tractor will not succumb to excessive wear.

All of the above methods will help effectively cope with typical breakdowns of the most famous manufacturers of motoblocks. They are equally successfully used by owners of agricultural units of the brands of Honda, Agro, Cascade and Neva.

The lawn mower works with jerks

Creating a beautiful lawn and maintaining it in order. The task is not easy. And to make it easier, you need a reliable assistant. Lawn mower. There are many good and different models on sale. And although everyone has one goal, in some respects they differ from each other. Let’s try to understand them.

What is a lawn mower?

According to the method of movement, the lawn mowers are divided into:

By the type of drive engine, select a mechanical, gasoline and electric lawn mowing.

Mechanical mowers on wheels are easy to operate, does not require electricity or gasoline, but requires significant muscle efforts. They are environmentally friendly, silent and allow you to regulate the height of the grass mowing.

The cutting mechanism is a cylindrical knife driven by wheels. This tool is good for caring for a young lawn, since the low speed of rotation of the knife prevents the extraction of grass with a fragile root system.

And we will consider gas and electric lawns below.

Trimmers for grass

Hand lawn mowers (trimmers for grass) are suitable for regular mowing the lawn on a small area even with an uneven surface, as they can be scored from any angle. Trimmer for grass. This is a holding bar with a knife for fishing line at the lower end. And at high power. Additionally with a round knife. The braid hangs on the belt on the operator’s shoulder, literally facilitating the work.

A trimmer for grass can be equipped with an electric or gasoline engine. Electric is located at the lower or upper end of the rod, and gasoline. Only on the upper.

The protective casing limits the inclined edge and protects the legs of the lawn mower from injuries. During operation, the left hand holds the rod handle (regulates, if necessary, the height of the grass mowing), and the right hand holds the handle using the engine control button.

The main advantage of trimmers. The possibility of mowing grass in uneven areas, near bushes and trees. But maintaining the same mowing height will not work.

Electric trimmers for grass

The electric trimmer for grass is powered by a household outlet. His merit may include:

Disadvantages of an electric trimmer for grass:

And the cable itself has a limited length: you can not mow away from the house.

trimmer for grass for batteries. The same as an electric one, but the motor does not work from a socket, so you can mow at any distance from the house. This is he is the main convenience. However, the area of ​​the mowing is determined by the capacity of the battery.

But this can work in any weather.

The convenience of mowing grass using a trimmer for grass is determined by several points, and one of them is the location of the engine.

trimmers for the grass of the bottom of the engine on sale a lot. Most often they are rechargeable low power. They quickly overheat, so they need frequent shutdowns. Protection against moisture and mechanical influences bad. They cannot work in morning dew and immediately after rain, otherwise a short circuit may occur. Trimmer for engine grass

Trammers for grass The upper part of the engine is more practical, more balanced and more powerful, requiring less effort when mowing and, therefore, more convenient to use. They have good cooling (less overheating) and, therefore, greater performance.

The upper trimmer for engine grass among trimmers with a top engine I would especially like to highlight backpacks. Their engines are attached from behind (like a school bag), which significantly reduces the load on hand and limits the movement much less.

Good version of the trimmer for grass anti.vibration system. This reduces vibration on the shoulders and hands, protects the hands and back of the mowing.

Powerful gas trimmers for grass reduce the load on the hands are equipped with an ergonomic handle, looks like a bicycle wheel.

The structure of a gasoline lawn mower

Before repairing the device, you need to figure out what it consists of. There are many models of gardening from different brands: self-propelled, non-self-propelled. All of them are arranged the same. The component structural elements:

The brushes sprinkle on the corner grinder what a malfunction

• Platform on wheels;
• gasoline engine (starter, carburetor, ignition and fuel supply system, air damper, filter, piston system, fuel tank.);
• manual handle;
• water.jet nozzle;
• cutting elements (knives);
• grass collector (container);
• Freshly cutting out unit;
• buttons, control levers;
• Corps (aluminum, steel, plastic).

Restoring the performance of electrical equipment

Mowers, inside of which electric motors are located, most often begin to be capricious due to oxidation of contacts. The terminals are covered with a layer of scale from excess humidity in the room or in another place of storage. It is also worth checking the absence of a break in wires in problem areas. For this operation, a multimeter or other tester type is used.

When a set of garden equipment contains a brush engine, we identify the performance. Brushes can wear out quickly, leading to a lack of contact. The reptity of them costs relatively little, and it is easy to find it in specialized stores, where they sell spare parts for such a technique.

Asynchronous engines are also in wait for the malfunctions. They refuse phase.drive capacitors. A similar situation is diagnosed at home is problematic. It can be detected by indirect symptoms:

• The sound of a buzz is heard;
• When starting, the case twitches slightly;
• significant heating of the motor occurs even at a slight load;
• Reduces are reduced.

It is worth diagnosing the condition on the tolerance/button and the voltage supply to the electric motor. Когда проведено тестирование описанных узлов, а нарушений в работоспособности не обнаружено, то вряд ли удастся исправить поломку газонокосилки своими руками. Then you will have to use the services of the corporate service.

Why the lawn mower is not started, the reasons

Figure out what has brought the device into a faulty state by disassembled it. You need to do this carefully and carefully, inside there are many small details that are easy to break.

• Blocking a cutting tool (cylinder) by an alien object. branches, sticks, hard grass, stones, etc.;
• The oil supply and fuel supply system is disturbed;
• The light of the ignition failed;
• stretched out, the belt broke;
• a small or too large gap between the details inside the structure;
• faulty device switch;
• Dirty fuel hose, ventilation grilles;
• Cunnered air filter.
