Every gardener invariably faces problems associated with the operation of garden equipment. In this article, we will answer the question why is the lawn mower stalling and how to deal with this problem.
Note that depending on which machine, gasoline or powered by electricity, you cut the grass, the solution to the problem will depend.
What to do if the engine of a gasoline lawn mower stalls?
- Very often the engine does not start after the "wintering". The most common cause is old fuel in the tank. Drain the old gasoline and replace it with new.
- Another reason for a lawnmower engine to stall is a bad spark plug. Take it out of the device and inspect. If there is oil or deposits on it, clean it or replace it with a new one. After you put the candle in place, make sure that the air damper is closed.
- Don't forget to check the oil in the crankcase. Its absence or insufficient amount can also cause the engine to stall.
- Check the air filter. It must be flushed with gasoline every 25 hours of operation.
- Often the lawnmower stalls immediately after starting. Most likely, the cause is a stuck crankshaft or piston. The problem can be eliminated if you carefully move these parts.
Why does an electric lawn mower stall?
- If the mower stalls, check the ventilation grilles. Maybe they got stuck in the grass. Clean them up and the problem will be fixed.
- Many motors are equipped with thermal protection. When the critical temperature is reached, they turn off on their own. Let the motor cool down and continue working.
- If the device does not start at all, check the serviceability of the electrical panel to which the device is connected.
- It is also possible that the switch on the lawnmower has blown. In this case, you need to contact a specialist to replace it.

Self repair lawn mowers
Repair of lawn mowers is carried out taking into account the mechanism of operation and the prerequisites for the breakdown of the unit. More often the device fails in 3-4 years after active operation.
Lawn mower repair is needed in the following cases:
- the device does not start;
- unit rapidly stalls after start;
- the motor is not running at full power.
Causes of the malfunction
Conditions for the failure of lawn mowers:
In the first case, it will be necessary to change the body, handles, knives and wheels for lawn mowers. When the blades are blocked, the machine stops mechanically. Such a breakdown is associated with an attempt to mow hard or higher grass. Mower repair consists in releasing the cylinder from stuck grass and scrolling it in the other direction.
When operating the mower with a blunt or warped blade, the lawn will cut unevenly. With all this, the device may vibrate or brake sharply.
In order for the device to work properly, it is recommended to sharpen the knives with a file (angle of 30 °). Otherwise, an abrasive tape is used. The gap should be between the 2 blades, touching the strip. The device cuts in periodically (for 15 seconds). If the knives are sharp, then the strip is removed, the gap is adjusted.
If the blades are not correctly positioned, the cylindrical lawnmower makes sudden and uncontrollable movements. Normally, the gap between the cutting elements should be thinner than a sheet of paper. Otherwise, the clearance is adjusted. For earlier, it is recommended to study the annotation of the device, pull the plug out of the socket. A loose connection causes a whistle. The device vibrates and rattles. Under the repair of the lawn mower, it is supposed to adjust the bolted connections.
If the belt is broken or stretched, then you need to change it. To do this, you will need to loosen the screws. Then the pulley moves, the belt is dismantled. A brand new part is put on a small, and then on a large pulley. The gear returns to its original position. The next step is to check the tension of the new belt. The deflection must not exceed 4 mm.
Malfunction of electrical models
The reasons for the sudden shutdown of the electronic lawnmower are associated with a broken cord or lack of current. In the first case, it is recommended to check the cable for a break. To change the power cord, you will need to unplug the plug from the outlet, open and remove the switch cover.
Before unscrewing the cable clamp? you need to understand the scheme of its connection to the switch. To disconnect the cord, a hexagon is used (diameter 1 mm). The clamp is released, the conductors are dismantled. A multimeter is used to test the cable for breakage. A new cord is installed as needed. With all this, the reverse sequence is observed.
Benzokosa!, On hot stalls,! Possible cause and elimination.
I immediately draw your attention to the fact that, unfortunately, this is not a carburetor !!! (My website is Facebook.
Lawn mower stalls or chokes when you press the gas
Even more information about the repair and selection of tools on our website www.LookTool.Ru, we are glad to everyone.
2nd case recommended connect another device to the mains. Electronic devices may not work if the fuse in the plug is damaged. To carry out repairs, it will be necessary to disassemble the plug. For this, a screwdriver and a tester are used.
Motor problems appear when the lawn mower overheats:
- as a result of long-term work;
- due to overload (the cutting element is blocked by some object).
In the first case recommended wait A couple of minutes to cool down the motor. In second case you will need to remove the stuck item. The efficiency of the cooling system depends on the condition of the air filter. A dirty device does not pass air well, which contributes to the shutdown of the device. Specialists recommend cleaning and changing the filter 1 time in 3 months (with the same operation of the lawn mower). If the electronic motor breaks down, there is a corresponding smell and noise. In this case, you will need to change the drive.
Motor failure
The design of a gasoline lawn mower, unlike an electronic counterpart, is more difficult. In some cases, the unit cannot be repaired. If the engine does not start or immediately stops, then it is recommended to check the ignition. To do this, you will need to dismantle the candle. A dry plug indicates a problem in the supply system, and a wet one indicates a carburetor. In such cases, repair work is carried out by the master.
If there is a dark soot on the candle, then it is replaced. All this does not take into account the cause of the breakdown of the lawn mower (carburetor setting, bad fuel). Often in gasoline models, the fuel hose is clogged. If gasoline does not flow, then the saloon is cleaned with a needle, and the fuel filter is replaced with a new one.
If a lawn mower Don't mow the grass, then inspect the knives. As needed, they are replaced with new cutting elements or sharpened on emery. In second case It is recommended to use safety goggles and thick gloves. You can sharpen the mower blades with the help of special tools included in the device kit.
If the blades are blocked by long grass, then it is recommended to turn off the mower. The cylinder is scrolled with a wooden stick (in the other direction) until it rotates freely. If a lawn mower does not work as a result of a switch malfunction, then it is recommended to check it and change it with a working analogue.
If there is no voltage in the outlet, the shield is checked. Some devices are equipped with thermal protection. When such a system is triggered, the ventilation grilles are checked for contamination. Use a soft brush to clean them.
The benzokosa represents the mobile high-performance tool for an ennoblement of personal plots and adjacent territories. With prolonged use, due to wear of parts or manufacturing defects, malfunctions occur that lead to the fact that the trimmer stalls or does not start. Since this tool is a rather complex mechanism, there may be several reasons why the lawn mower stalls.
Why does the trimmer stall
There are two main ways to fix problems: transferring the scythe to a specialized center or solving the issue yourself. The first option is suitable for those who are ready to pay a “tidy” sum to restore the unit’s performance, and the second for someone who has basic locksmith skills and can independently deal with the causes of breakdowns and ways to eliminate them.
It is currently customary to classify breakdowns, according to which the lawn mower stalls, into the following categories:
- mechanical damage to the crankcase of the internal combustion engine, malfunctions of the cylinder-piston group (CPG);
- breakdowns associated with the supply of the fuel mixture (air filter, carburetor);
- malfunctions due to damage to pipes, hoses, cables or ignition circuit.
Motokosa stalls at high engine speeds
During operation, a situation arises when, when the fuel mixture supply button is pressed, the unit speed does not increase, but decreases. A malfunction of this nature can be caused by:
Fuel hoses for lawn mowers with filter
- etching atmospheric air into the combustion chamber;
- problems with the circulation of the fuel mixture;
- clogging of the breather in the fuel tank cap (cleaning the hole with a thin sewing needle);
- incorrect carburetor adjustment.
When air leaks during the operation of the internal combustion engine, it is necessary to check the tightness of the connection of the nozzles and the integrity of the gaskets in the CPG. The problem with the circulation of the fuel mixture can be solved by eliminating blockages in the fuel pipes leading to the carburetor. If a vacuum occurs in the tank and the fuel mixture does not reach the carburetor, it is enough to clean the breather with a thin needle and blow it with air.
Gasoline trimmer stalls at idle
Often, when the speed is reduced, the engine of the lawn mower stalls and does not maintain idle speed when it is restarted. The main reasons for the occurrence of such a breakdown include contamination or misalignment of the carburetor, as well as clogging of the air filter.
Gasoline trimmer stalls at idle
If the optimal settings of the carburetor are violated, it is necessary to clean it and re-adjust it. A clogged trimmer air filter can be dealt with by soaking it in a solution of common household detergent for several hours. If self-cleaning did not help to cope with the blockage, then it is better to purchase a new filter element in accordance with the instruction manual.
After the events, the user for a long time will not encounter a situation where the trimmer stalls at idle and only functions when gas is supplied.
Trimmer starts and then immediately shuts off.
Trimmer stalls: causes and troubleshooting was last modified: July 22nd, 2018 by Administrator
A reliable and simple tool for cutting grass on a garden plot - a lawn mower, is extremely in demand. However, it may break. Repair required. As a rule, the repair of electric lawn mowers is carried out in service centers.
( ArticleToC: enabled=yes )
In order not to transport a sufficiently voluminous apparatus to the workshop, a number of malfunctions can be eliminated with your own hands.
Why won't lawn mowers start?
To answer the question, you need to understand that all breakdowns are divided into mechanical and electrical. The first ones include faults:
- knives;
- wheels;
- handles;
- corps.
To the second - everything related to the engine, whether it is electric or gasoline.
It is not difficult to repair blunt knives on your own, since they are removable and you can sharpen them with ordinary emery, maintaining a sharpening angle of 30 degrees. In case of malfunctions of other parts, i.e. body, wheels, handles, they will also need repair or replacement.
In battery devices, battery failure is added to this problem. It is more difficult to cope with the repair of a lawn mower equipped with a motor, i.e. petrol and electric lawn mowers.
In the first case, the problem of overheating and overload, as well as malfunctions in the oil and fuel supply chain, are added to possible breakdowns. An electrical breakdown can also be caused by overheating or overload, since not all models are equipped with protection.
Overheating is caused by running the unit for a long time with the air filter in poor condition, making it difficult for sufficient air to pass through.
You will have to cool the electric motor by disconnecting it from the power supply and replace the filter. In the future, in order to avoid repairs to the electrical apparatus, it must be cleaned at least once every three months.
The appearance of extraneous noise or smell indicates that the electric lawn mower needs repair. Not everyone will do it with their own hands, because the drive will need to be replaced.
Electric lawn mower does not start or stalls
Sooner or later, many are faced with the failure of the lawn mower. This happens, as a rule, after 3-4 years of active operation or after the device was stored in an unheated room in the winter.
The lawn mower is out of order if:
- does not start;
- lawn mower stalls shortly after starting;
- the engine does not run at full power or intermittently
Engine problems arise over time for all devices, regardless of whether a simple “Chinese” or an expensive “Japanese” is on it. The moment is unpleasant, but you should not be upset, just as you do not need to rush to the service center. You can try to repair it yourself.
How to identify the cause of the breakdown?
It is necessary to start repairs, guided by the principle “from simple to complex”, i.e. it is recommended to start the repair by checking the presence of gasoline in the tank. If the gasoline machine stopped starting after wintering, the fuel should be replaced.
After all, fuel, unfortunately, is not always of decent quality. Therefore, during prolonged inactivity of the device, it may delaminate or form a precipitate. And engines are sometimes very sensitive to the quality of fuel.
If there is no doubt as to the latter, but the mower does not start, it is necessary to check the spark by removing the wire with the cap from the candle, unscrewing it with the key supplied in the kit.
Attach a candle to a clean metal surface (without paint) of the engine, having previously put a cap on it, and asking someone to pull the starter.
If no blue spark appears, the spark plug needs to be replaced.
If an unstable and weak spark appears, the candle will need to be cleaned with a needle file or sandpaper.
They also change it if black soot is found on the surface, regardless of whether it was formed due to poor fuel quality or an incorrectly tuned carburetor.
Another problem that is easy to fix is a clogged fuel hose. Check this by disconnecting it: if the fuel does not flow, then the filter or saloon is clogged. The filter will have to be replaced, the saloon can be cleaned with a needle.
Well, if after that the mower will work. However, the cause of the malfunction in 90% of cases lies elsewhere - the failure of the carburetor, which will require repair. It is possible to cope with the repair, having enough experience. In its absence, the help of a service center will be required.
How to clean a carburetor?
You should start by checking that there are no open sources of fire nearby. Repairs must not be carried out indoors. This is fraught with leakage of gasoline.
Use a flat screwdriver to unscrew the screws to remove the plastic casing of the air filter from the motor. The removed filter is checked for clogging, cleaned with a vacuum cleaner or replaced with a new one (if the condition is unsatisfactory).
You also need to remove the inner filter cover, which is located under the casing. This, by unscrewing the bolts, is easier to do with a spanner wrench. An air hose is attached to its inner side, which will also have to be removed.
Finally, we got to the carburetor of a device that can be dismantled. Having disconnected the fuel hose going to it from the tank, i.e. removing the clamp, turn the hose, trying to remove it from the nozzle. You need to do the job carefully. After all, if there is fuel in the tank, it will definitely spill.
The carburetor is attached to the engine with two bolts, which require a socket head to unscrew. When unscrewing the second bolt, try not to drop the carburetor so as not to damage the spring suspension.
The next step is to remove the return spring. It is more convenient to carry out the operation from the side where it is attached to the motor. Now you can remove the throttle cable by gently turning the carburetor counterclockwise.
After removing the carburetor, unscrew the bolt securing the fuel chamber cover.
Cleaning is done with a special liquid or WD-40 and a copper wire from which the insulation has been removed.
Finally, you can remove the plastic float under the chamber cover that regulates the level of gasoline, for which the pin is first removed.
The camera must be cleaned of plaque. The insides of the carburetor are abundantly moistened with WD-40 (or equivalent), wiped dry. After repeating the operations several times, they clean the copper core fuel channels, purge them, since their pollution is the main reason why the engine stalls or does not start.
After completing all the steps described, assemble the carburetor in the reverse order.
After installing it in place, connecting the hose, air is expelled from the fuel chamber. This completes the repair.
After the described manipulations, the equipment will start easily and work stably.
Malfunctions of electric lawn mowers
If the electric mower is silent, the cause may be a power outage and a broken cord. To check if there is current in the network, use another electrical device plugged into the outlet. The cord must be inspected and replaced if a break is detected. Disconnect it with a hexagon, and check for an open with a multimeter.
As is the case with petrol lawnmowers, overheating and overloading (blocking the element with a foreign object) can cause an inoperative electric motor. The troubleshooting procedure is the same as described above.
Electric Mower Fault Repair
Jamming of the knives can be caused by long grass wrapped around them. To repair, you need to disconnect the device from the network and twist the cylinder in the opposite direction.
If the electrical device is silent, the drive belt needs to be repaired as a result of wear and tear: it can be stretched or broken. This means that you can not do without replacement, for which you need to remove the protective cover.
The new belt is first installed on the small gear of the electric apparatus, then put on the large pulley, and turning it.
To replace the power cable of this electrical device, it is necessary to de-energize the device and unscrew the cover.
To disconnect the cord, insert a hex wrench into the hole with the wires, releasing the clamp.
Install the new power cord in reverse order.
The reason may also be in a faulty power switch, which is simply replaced with a new one.
Repairing an unexpectedly stopped electric motor
If the engine was running, but suddenly stalled, you need to check the crankshaft and piston - perhaps they are stuck. This happens due to the lack of oil in the crankcase. With this breakdown, it is better to contact specialists, as in the case when the lawn mower electric motor needs repair.

Preventive work
For trouble-free operation of the lawn mower, the owner must carry out its regular maintenance after the end of the working season, i.e. prior to winter storage. It will cost less than repairing or buying a new electrical device.
Keeping your mower clean is one of the most important things to keep your electric mower running smoothly. Grass that has accumulated under the deck causes erosion of the metal parts. A compressor or blower will help remove the remains of mowed weeds.
The mower's electric motor is air-cooled, so it also needs to be kept clean, which is the key to efficient operation. Suitable for cleaning the cooling fins with a soft brush and compressed air.
Timely oil changes, as indicated in the user manual, will be the key to long trouble-free operation, as well as periodic cleaning of the air filter.
With some experience, it is easy to repair lawn mowers with your own hands. The video below will help you with this.
