The lawn mower does not go back the reason. Does not stop
The most frequent breakdowns of lawn mowers: how to eliminate the malfunction yourself?
Lawn mowers are one of the main garden supplies, without which large lawns owners are surely not to do with. However, like any other machine, the mowing cannot avoid damage.
If this device does not work properly or does not turn on properly, do not rush to the service center. if you correctly determine the problem, you can easily solve the problem yourself.
The most common reasons for the breakdown of the lawn mower
Before taking any more serious actions, first check the three most important factors-fuel, oil and ignition. It is for these reasons that many different problems sometimes arise with the mowing.
The oil level must be checked every time before starting work. It is very important that there is not only a shortage in oil, but there is not too much. otherwise excess oil will fall into other details and damage them. The same thing can happen if you put a mower in the wrong position.
It can only be lifted when the spark plug is directed down, and you can not turn towards the fuel tank. The oil in the lawn mower must be changed after about 50 hours of work, at least once a year. The amount of oil poured into a mower depends on the model.
How electric lawn mowers are arranged
The general layout of electric lawn mowers is the same.
An electric motor is installed on the wheel chassis, directly or through the belt gear, a rotating cutting tool that cuts the grass at a certain height.
However, despite the general principle of work, all braids are divided into types of:
Type of chassis
Most lawn mowers are equipped with a four.wheeled chassis with a rigidly fixed axis of the front wheels, so for rotation, especially during the mowing of grass, it is necessary to press a little on the handle to tear the front wheels from the ground.
10 second fix! Lawn mower pull cord not going back in recoil not working great easy trick!!!
Indeed, during the turn, the direction of movement of the apparatus and the direction of rotation of the wheels do not coincide, which is why the latter resist the side movement, and the cooler the turn, the stronger they resist the movement.
Some models are equipped with front piano wheels, the axis of which does not have rigid fixation, so that the axis of their rotation clearly follows the trajectory of the lawn mowing, therefore, regardless of the steepness of the turn, they never move sideways.
Almost all three.wheeled lawn mowers are equipped with front piano wheels, so it is much easier to control them than four.wheeled. However, the most maneuverable are two.wheeled models, because regardless of the steepness of the rotation of their wheels never move sideways.
Collector and asynchronous motors of alternating current are installed on electric lawn mowers.
The former have somewhat smaller efficiency, but it is much easier to perceive high loads or overloads, the latter more effectively turn electrical energy into rotation of the shaft, but greatly increase the cost of the apparatus.
This is caused by both the highest cost of collector engines, and the need to protect them using belt transmission. The main difference between collector engines is the presence of contacts (collectors), therefore they are sometimes called collector engines, confusing with direct current motors.
Devices with a collector engine are well suited for mowing lawns and other territories planted with cultural vegetation, however, their use in areas overgrown with wild grass, especially tall and thick, is undesirable.
After all, such vegetation sharply increases the load on the engine windings and the brushes of collectors, as well as on the details of the belt transmission, all this leads to a rapid decrease in their resource. Asynchronous engines are deprived of this drawback, however, when working with them, it is necessary to use different methods of mowing well.groomed and high grass.
Type of cutting tools
The vast majority of the devices are equipped with a rotary cutting tool, that is, knives mounted on the engine shaft, which rotating, cut the grass and throw it through the side or rear window. During the rotation, such a knife is created by a vertically directed air flow that raises crushed grass and provides an even surface after mowing.
To some extent, the rotor cutting mechanisms can also be attributed to fox, which are installed on wheeled trimmers for the grass, only instead of a metal knife they cut the grass dispersed to huge speeds with a fishing line.
The main drawback of the knives of the rotary mechanisms is their vulnerability before solid obstacles, because rotating at high speed, they stock up enormous kinetic energy. Therefore, in a collision with an obstacle, not only defects of the cutting edge appear, but also the shape of the knife is often disturbed, due to which an imbalance appears, leading to strong vibration during engine operation.
Part of the lawn mower is equipped with a drum cutting mechanism, which is a hollow drum of steel plates, as well as a sharply.mounted knife operating on the principle of scissors.
The rotating drum captures the grass and leads it to the knife, which cuts vegetation, so such a mechanism is deprived of the main lack of rotary analogues. After all, the speed of rotation of the drum is much lower, which means that the energy accumulated in it is not enough to damage the plates, in addition, the knife does not contact obstacles at all, so defects do not appear on its cutting edge.
Method of ejection and processing of grass
The knife rotating at high speed not only cuts off the grass, but also gives it acceleration, so that the centrifugal force presses the cut vegetation to the deck, so it flies through the rear or side window, depending on the configuration and the operating mode of the mower.
If both holes are closed, then the cut grass passes between the ends of the knife and the walls of the deck, after which it falls down.
When working in this mode, falling fragments are quite large, comparable to those that fly through the windows provided for this.
If, together with a regular knife, set additional (mulching), then the size of the grass falling to the ground will be reduced several times, so this mode of operation is called mulching. All rotary braids can not only throw the grass back, but also collect it in the grass collector, this mode is in demand where for any reason you can not leave mowed vegetation on the site.
Drum mowers work a little differently. rotating, the drum accelerates the fragments of cut vegetation inside it, which are pressed to the tightly adjacent gas mowing housing. Therefore, at the time of passage through the output window, they fly out under the influence of centrifugal force.
All drum braids are equipped only with the rear emission, however, part of them includes a grass collector, so such models can be used not only for haircuts, but also to remove mowed grass from the site.
Way to travel
All electric lawns, regardless of the type of cutting mechanism, are divided into self.propelled and non.self.propelled. The former is equipped with a clutch and belt transmission, as well as a gearbox that lower the speed of rotation of the engine to the optimal level for wheels.
How to use electric lawn mowers correctly?
The use of these devices implies not only the mowing of grass, but also the maintenance carried out before and after the mowing.
In addition, for new devices, the correct assembly is also needed, because most of them are delivered in the form of individual nodes located in a common box.
Since the assembly methodology of each model is individual, we recommend that you carefully read the corresponding section of the instructions for the operation of the device, which is also often called the user manual.
Preparation for work
Preparation for work begin the external inspection of the device, paying special attention to the integrity of the insulation of the wires, including extension cords, in addition, do not forget to check all threaded joints. In addition, carefully inspect the mowing housing, if cracks or dents are found on it, then you can’t use such a device, first it must be disassembled and the condition of the internal parts and mechanisms is checked.
If everything is in order, then install the device on a flat surface, connect via extension cord to the outlet and turn on the engine. the mitch should work without knocking or vibration. After 10–20 seconds, if the smell of smoke does not appear, turn off the engine and disconnect the extension cords from the network.
then first eliminate their causes and only after that, having completed another check, proceed to the mowing of grass. In addition, do not forget to check the condition of the cutting edge of the knife, turning off the device from the outlet and waiting for the end of the rotation of the engine shaft.
If the knife is stupid or damaged, then replace it with a new one or sharpen it with subsequent balancing.
In drum mowers, check the condition of the drum plates and sharpening the knife, if the knife is stupid, then sharpen it, strictly following the operating instructions.
If you are planning to work with the grass collector, then check its condition and install it on the lawn mower to make sure that it adjacent.
Having discovered a loose fit of the traumatic collector, remove and eliminate the reason that is most often noticed during cleaning the grass.
Also check the ease of rotation of the wheels, if one or more of them rotate tightly, then check the condition of the bushings or bearings, if necessary, cleaning them from the grass.
If it is recommended to lubricate bushings or bearings in the operating instructions, then do this by finding the slightest resistance to rotation.
In addition, remove any solid items from the site, including:
The mowing of the lawn
Let’s move on to the question of how to mow grass properly. Start the mowing of the grass by unwinding the extension cord and laying it with large loops to exclude twisting when removing the mower from the outlet. Can be laid with a snake or in any other way, the main thing is that during the removal of the mowing he does not get confused and does not be in the way of moving the mower.
Then set the optimal section for this section, then first connect the cable to the outlet, then the lawn mower to the cable.
For ease of work, fix the cable using special mounts to exclude disconnecting the plug of the lawn mower from the cable socket.
On the vast majority of models, the engine is turned on using a button and lever, this is described in more detail in the operating instructions. Having turned on the motor, move the mower in the direction of the outlet, the non.self.propelled model smoothly push you in front of you due to your physical strength, activate the self.propelled drive using a special lever.
The speed of movement should be such that even a meeting with thick grass does not lead to a decrease in engine speed (they are controlled by ear). If the revolutions have fallen and the sound of the mower has changed, then stop moving forward and hand it a little, then continue moving forward, but already at a lower speed.
When working in the rear emission mode, including with an installed grass collector, a snake is the optimal trajectory of movement along the area of the optimal trajectory.
To do this, first, on the edge of the site, remove to the maximum distance, then unfold the mower and shift to the width of the mowing sideways, then move the device towards the outlet.
If the turn is right, then the extension cord should be to the left of the mower, if left, then on the right. To reduce the likelihood of a wire fall under the knife, it can be thrown through the elbow of the corresponding arm. That is, when turning to the right to throw through the left elbow, and when turning left, through the right.
When working in the side emission mode, the cable should always be on the opposite side, and to reduce the likelihood of falling under the knife, it can also be thrown through the elbow.
When working with the grass collector, follow not only the indicator of its filling, but also the sound that the lawn mower produces. If the sound has changed, but there is no section with thicker grass, then the grass collector is full, so it is necessary to stop the engine and remove the mowed grass.
What clothes to use
The choice of clothing affects the safety and efficiency of mowing grass.
A dangling sleeve can hook and block the lever of the knife or wheel drive, and the probability of falling when working in shoes on slippery soles is very high.
Therefore, to work with a lawn mower, you need:
- shirt with long fastening sleeves;
- long pants made of dense fabric;
- foot covering the leg on strong corrugated soles;
- protective glasses or mask;
- Hat or cap (on a hot sunny day).
How long can you use?
The optimal operating mode for each model is described in the operation manual for the lawn mower.
If this document is not available for some reason, then adhere to the rules 15/10, that is, mow the grass for 15 minutes, then wait 10 minutes until the motor cools down.
How to make repair of the lawn mower with your own hands?
Those who have land are very familiar with what struggle is weed.
Especially when it often rains and the grass grows not by the day, but by the hour. Earlier, and sometimes even now, this issue was resolved with the help of a good old braid for grass.
But technologies are not standing still and now in this case, assistants such as electric and gasoline lawn mowers help.
The gasoline mower has several significant advantages over electric, such as mobility and lack of danger of electric shock. But there are many drawbacks, for example: high price, a lot of noise, expensive fuel and significant weight.
Electric mowers are cheaper, easier, work on inexpensive energy, and are not difficult to maintain and repair. These advantages become the main reason for their great popularity among buyers of this type of technique.
But despite the pretty good quality, improper operation and a lot of load, they can disable the device. In such cases, you should not immediately carry the device to the repair shop, but try to find and eliminate the cause of the breakdown yourself. over, as mentioned above, electric lawnmands do not have as many nodes and details as gasoline.
The main thing is to have some tools and faith in yourself. In this article, I will just show you how I did my own repair.
AL-KO, the lawn mower of the company, has serious problems in work, namely: the engine stop without load and its strong overheating, was taken as an example. The motor stops, buzzes and start it again, only re.pressing the “Start” button helps. The button has to restart almost every 30 seconds, and with further work and more often.
Of course, you can work, but it is very annoying and gives the feeling that somewhere the problem is. Therefore, I wanted to figure out where?
After the mower was working within an hour, the engine temperature was measured. It was impossible to touch him with a finger. He directly radiated heat. If you continue to pay attention and continue to work on such a mower, an electric motor will inevitably fail.
It is necessary to determine the cause of the motor overheating. To do this, remove the top cover of the case, under which the engine is located and its power chains.
The lid is held on six screws with a hat under a cross screwdriver.
Unscrew these screws and remove the lid. upward.
Having removed it, you can see the impeller, the capacitor, two connectors and the engine itself.
At first glance, no special problems are invisible. The engine winding darkened slightly from the temperature, but so far it is not critical.
To more carefully inspect the capacitor, it is necessary to unscrew the mount and pull it out.
The capacitor of some external damage did not show.
To check it, you need to disconnect the capacitor and feed the engine for a short time. If he did not start and began to buzz, then the capacitor is intact, because the engine was launched with him. Disconnect the power and connect the container connector back to the engine circuit.
Next, try to twist the impeller. It is mounted on the axis of the rotor and rotates rather tight.
And the reason for such severe rotation is a mechanical brake, which for safety stops the engine rotation when the power is turned off.
It looks like a sleeve that moves freely from top to bottom, along the rotor axis.
Когда напряжение на двигатель не подано, эта втулка прижимается верхней частью о крышку, на которой приклеено две резиновые полосы. Thus, the knife is inhibited on the rotor shaft.
When feeding, the brake sleeve under the influence of the magnetic field is drawn to the center of the rotor and provides free move.
With a careful examination, this sleeve with the brake noticed that at the time of turning on the engine, the brake is retracted and gives the shaft free rotation, but after 2-3 seconds it is released again and begins to slow down the motor. This should not be. Hence the stop of the knife during operation and overheating of the engine.
To find out what is the reason for this work, you need to remove and disassemble the engine.
To do this, disconnect the connectors and put the device on the side to get to the clamping screws. Access to them closes a knife with mounting elements.
To remove it, first you need to unscrew the knife bolt (cm. Figure below).
Direction of rotation, like a regular bolt, and not with left thread. That is, unscrew it counterclockwise, and tighten the clock.
The head of the bolt is plastic, so using the key, it must be well planted so as not to “lick” the edge.
After extracting the bolt, the knife and its plastic disk are removed.
Under it is a height sleeve. With its help, you can slightly lower the knife.
Adjustment is carried out by the washers put under the sleeve (see. drawings below).
We remove everything, only the engine shaft and the hexagonal screws of its fasteners remain.
The key for these bolts has a distance between faces of 6 mm. Unscrew them counterclockwise. Removing the last screw, with one hand, hold the engine.
Next, put the mower on the wheels, and clasping the engine with our hands. we raise it.
To disassemble the motor, you need to free tightening studs. We unscrew them all.
Remove the impeller with two screwdrivers.
We proceed to the removal of the back cover. A wooden block and a hammer will help this.
But first you need to mark the position of the covers with something sharp to the engine body.
Put the engine on the side and hit with a hammer, through a wooden gasket, on the rear shaft.
The motor at that moment should hold another person.
We hit until the axis comes out of the bearing to the end.
The causes of the malfunction
Since all the trimmers for grass that can work with the disk are arranged the same way, the reasons why the gear circle does not rotate with the motor turned on are also the same, that is:
- The fixer in the gearbox is forgotten;
- licked slots of the protective washer of the gearbox;
- the engine is turned on, but does not work;
- clutch on gasoline devices;
- the shaft tips were erased;
- The shaft burst or broke;
- Reducer is destroyed or jammed.
The fixer in the gearbox is forgotten
This is not even a malfunction, but a consequence of the inattention of the operator, who for any reason was removed by one and put the other cutting tool. Inspect the gearbox, if it has a latch, then you forgot to pull it out.
Remember, the inclusion of an electric engine with an installed latch can lead to an inter.flip circuit, although the launch of a gasoline power unit is safe, because at idle speed the clutch turns it off from the shaft.
Licked slots of the gearbox protective washer
If the disk rotates at least a little, but stops from any load, while the clutch of a gasoline trimmer for the grass is completely regular, then remove the cutting tool.
Then remove the protective washer of the gearbox, which is also called the lower slotted plate.
Inspect the slots on it and on the gearbox shaft. If their faces are licked, then the puck needs to be changed, and the gearbox is repaired. If the edge of the slots is clear, then the problem is in some other.
The engine is on but does not work
The owners of the electric focus are faced with this problem, because their engine works much quieter than a gasoline power unit.
To make sure of the electric motor, turn it off, and then turn it on again, while the trimmer for the grass should jerk a little around your shaft.
In addition, an air flow should come out of the ventilation windows. If all this is, then the power unit works normally, which means that the problem is not in it.
The main sign of the operation of the gasoline engine is a characteristic sound that appears after starting the unit.
The lawn mowers are equipped with a centrifugal clutch, which works when the engine reaches certain speeds.
The pads are attached to a rotating basis with one side, the second edge is held by a spring, the elasticity of which determines the speeds at which the clutch will work.
When the friction pads of the pads are worn out, they do not transmit the torch of the bar to the fullest, which is why the disk either does not spin at all, or spins very slowly and stops at any load.
If the cutting tool is spinning and does not stop during the mowing of the grass with an increase in speed, then everything is in order with the clutch.
If the tooth circle does not rotate at any engine speed, then the problem is not in the adhesion.
After all, even with completely erased friction lining, it transfers to the shaft at least a little energy, so that the cutting tool, albeit slowly, but rotates.
The shaft tips were erased
This is the most common problem, because when working with the disk, the tips experience huge loads, and incorrect assembly after service accelerates their wear.
To check the condition of the tip, disassemble the shaft, disconnecting it from the engine and taking off the gearbox, as well as dismantling it, if it is provided for by the design.
Inspect the tips. If the faces are clear and they are deeply included in the clutch and gearbox, then the problem is not in them.
Burst or torn the shaft
Devices with a twisted shaft are not designed to work with a knife or disk, but their owners sometimes neglect this requirement.
To make sure that the shaft is working, separate the bar and start the engine if the tip rotates, then everything is fine.
Then remove the gearbox and check the second part of this part. If the rod is indispensable, then immediately remove the gearbox. The lack of rotation of the tip, as well as its torn movements with a change in revolutions indicate that with the shaft of the problem.
Reducer is destroyed or jammed
If all other reasons are excluded, then the problem lies in the gearbox that is destroyed or jammed. Remove the gearbox and pull the shaft from the bar, then insert it into the gearbox and cram it several times, holding the output shaft with your fingers.
If the rotation is transmitted normally, without jerks, then bring a trimmer for the grass home and there completely disassemble this mechanism.
This is the only way to check its real state and evaluate the degree of wear. Remember, even if you recently smeared it, it is better to rinse all the details in diesel fuel and lay a new lubricant, this will extend the service life of parts.
If the gearbox is serviceable, but the disk still does not spin, then you need to check everything new, because somewhere you missed something.
The most common problems
Here are the most common malfunctions:
- the engine does not start;
- The motor stalls arbitrarily;
- The engine does not gain momentum or does not hold them;
- Immediately after the start of the mowing, the engine speed falls and it stalls or works with interruptions;
- smokes strongly;
- It goes badly;
- does not stop even after the operator released the wheel drive lever;
- shakes hard;
- Poorly cut the grass.
The engine does not start
There are quite a lot of reasons why the motor does not start:
- empty fuel tank;
- a air filter is clogged;
- a muffler is clogged;
- The ignition switch is installed in the wrong position or faulty;
- The air damper control lever is in the wrong position;
- faulty candle;
- broken or clogged carburetor.
To establish the real cause of this defect, you must first conduct a full external inspection and make sure that the openings of the air filter or muffler are not clogged, there is gasoline in the tank, and the throttle control lever and the ignition switch are in the correct position.
If everything is in order with this, then it is necessary to carry out pre.launch work, including cleaning air or fuel filters, described in detail in the instructions for the operation of the mower, and then try to start again.
After making sure that the motor still does not start, the mowing is placed on the table and proceed to a more detailed search for the reasons.
First, the spark plug is twisted and tightly plug the candle hole with your finger, then smoothly, but quickly and strongly pulled the hand starter cable or pressed on the electric launch button.
The moving piston should create sufficient air pressure so that it pushes the finger and goes outside. If this does not happen, then the motor needs serious repairs, which is difficult to make at home, so it is better to take the mower to a specialized workshop.
After all, the reason that the piston does not move after the starter’s cable or rotating the shaft of an electric starter may be:
- Damage to the starter, because of which he does not transmit the energy of rotation to the engine shaft;
- The cut off the flywheel that connects the flywheel and the starter with the engine, and also provides the correct ignition angle.
To eliminate both malfunctions, not only tools, but also skill are needed, so those who do not have the skill of repairing any engines are better not to try to eliminate such problems on their own.
If the piston moves, then you must first check the fuel supply, for which the candle is thoroughly wiped with a dry clean rag, then screw it into place, and the regulator of the position by the air damper is placed in the “OFF” position, as during the start of the engine.
After that, the fuel is pumped up (if the engine design provides) and twitch the hand starter cable several times or pressed on the electric starter button and hold it for 1-3 minutes.
Then, the lever of the air damper is transferring to the “ON” position and the candle is unscrewed, which is carefully examined.
Wet contacts indicate that gasoline enters the engine and the problem of ignition, and dry contacts say:
In both cases, knowledge and equipment are necessary for proper diagnosis and repair, therefore, it is better to take the device to repair the apparatus to a specialized workshop.
If the fuel comes, then it is necessary to check the external condition of the ignition coil and the high.voltage wire. If they have cracks or poor contact as between the wire and the coil, so at the place of connection of the wire with the candle tip, they must be replaced.
If everything is fine, then you need to check the spark, for which you can use both a deliberately serviceable candle and a bolt suitable in diameter, which is inserted instead of a candle in a high.voltage wire.
The operations described below, if they are performed with errors, can damage the ignition coil, so if you are not sure that you can do everything right, then it’s better not to take risks and entrust such a check to professionals.
The candle is leaned with threads against the ribs of the engine cooling shirt, and the bolt is placed so that it does not come into contact with the mowing case or its engine, and the distance from it to the cooling shirt was 1-2 mm.
After that, disconnect any wire going to the ignition switch, then pull the lever of the manual starter or press the electric button and see if the spark will appear.
If there is no spark, then the device does not start for one of the reasons:
For the repair of these damage, skills and equipment are needed, so those who do not have them are better to trust professionals. If there is a spark, then the problem is in the spark plug, so after replacing it will work.
The motor stalls arbitrarily
The most frequent reasons why the engine stalls during operation are:
- Dirty air filter;
- Dirty fuel filter (only for models with a fuel filter);
- faulty ignition switch (does not completely open the ignition circuit);
- damaged insulation of the ignition shutdown wires;
- faulty air damper drive;
- the tightness of the ignition coil is broken or its winding is broken.
The primary inspection is performed in the same way as described in the previous section. If everything is fine outwardly, then carefully examine and feel all the wires suitable for the switch that blocks the operation of the ignition system, is possible somewhere damaged and when contacting the naked metal of the case, there is a short circuit that extinguishes the spark.
A gasoline lawn mower is a complex motorized equipment that needs proper timely maintenance and periodic repair.
Now you know what malfunctions can independently eliminate most of the owners of gasoline lawners and how to do it, and in which cases it is better to contact the workshop.
When the lawn mower does not start
Depending on the area of the lawn and the growth of grass on it, the owners choose the optimal technique in characteristics. It is several types:
Also, the restoration of lawn mowers with your own hands will be required if the conditions of winter storage are inappropriate. For example, after use, there were no cleaning surfaces or there was no off.season preventive maintenance. As a result, various problems are manifested:
- frequent sharpening of the lamp of the lawn mower is required;
- just does not start a lawn mower;
- The motor starts up, but through a short gap the lawn mower stalls;
- malfunctions of the carburetor appear, which requires not only disassembly, but also cleaning with repair;
- Do.it.yourself renovation of the lawn mower is required with a significant reduction in power during operation.
You should not go to an expensive service center. Many problems can be solved with minimal costs and repairs on your own.
After each use of the tool, it is necessary to clean the cutting elements. Change the oil regularly and perform a minimum risk.
Problems with the mechanical part
The mechanical system in lawn mowers with different drives consists of the following structural elements and nodes:
- knife (rotary or cylindrical type) or fishing line;
- transmission mechanism;
- grass collector and grass emission devices;
- wheels, handles and housings.
The failure of the cutting element
The most commonly damaged (for example, bend) or knives are blunt, the fishing line for the trimmer ends. This is easily detected with a simple visual inspection.
The fact that the cutting nozzles have become swept away is evidenced by uneven cutting of herbal stems when the lawn mowed.
Over time, knife fastening can weaken. Their balancing during rotation is disturbed, and vibration, whistle, rattling appear. If the knives are damaged, then during operation the mechanism will begin to perform unguided, sudden, sudden movements. To eliminate the malfunctions of this kind, the cutting elements are set to the right position, replaced with new ones or repaired. If possible, then the blades are pulled again.
Sounds and vibration during work
Uncharacteristic sounds, vibration, rattling appear during the operation of the unit, when the fasteners of its structural elements are weakened: body, engine. These phenomena are more often found in gasoline models, because their motor fluctuates more strongly than the electric motor. To eliminate these phenomena, check all the connections, pulling up the bolts if necessary. It happens that the whistle during the operation of the unit arises due to the entry into an outsider that blocks the video in the aerator. In this case, it is enough just to get it so that the sound stops.
Cutting nozzles do not rotate
Often, when mowing a high herbal cover or hard herbal, cutting nozzles cease to rotate due to grass clogging. This problem in most cases (if it has not led to more significant negative consequences) is easy to solve with your own hands, just picking out a stick with a stick.
Damage to constructive details
Damage to the wheels, handles and housing rarely happen. If they are significant, then they change these structural elements. Methods of repair, with its possibility, in each case, depend on the material of broken parts. they can be plastic, aluminum, steel.
With prolonged operation, the mower wear out, stretches, and then the belt breaks off. At the same time, the device’s gasoline engine works, but the knives do not rotate. Self.propelled models can also break off the wheel drive belt: then they stop and do not go. Sometimes the clutch cable simply stretches and it needs to be adjusted.
Repair of lawn mowers of electric
Many owners of lawn mowers sooner or later face technical problems of this technique. Often problems arise after several seasons of active use or after the equipment spends the winter in a cold unheated room. And it doesn’t matter what the engine is installed: high.quality Japanese or simple Chinese, over the years it will still begin to fail. But you do not need to be upset and rush to the service center. many breakdowns can be eliminated on your own.
The traditional “pushing” technique has long received knives from electric engines, which significantly facilitated the process of work. This type is still very popular, especially among those who want to get a beautiful lawn, but nothing can be compared with the relative novelty of the domestic market. rotary mowers that easily cut off even the highest grass.
Rotor.type mowals are powered only from electric networks, and cylindrical ones. both from the network and from batteries.
Both types are represented by different modifications. Gasoline braids will not be considered separately, but the proposed options for eliminating breakdowns in most cases are identical. You always need to have at hand a manual or apply for advice to professionals if there are problems in care or use.
Their composition contains spiral knives, the totality of which resembles a cylinder. A large toothed pulley placed at one end sets the belt (in some cases, the chain), on the other hand, is worn on the second, a small pulley attached to the engine shaft. The engine can set in motion and a rink that moves the equipment on the ground.
- Switch lever.
- Emergency shutdown button and protective lock.
- Air intake grille.
- Gap regulator between knives.
- A motionless knife.
- Knife cylinder.
- Large toothed pulley.
- Drive belt.
- Drive pulley.
- Lever that regulates the height.
- Electric motor.
- Power cable.
When the cylinder rotates, the knives press the grass to a motionless knife attached to the cylinder, thereby creating a cutting effect resembling the principle of action of scissors. Any damage, even the most insignificant, wear, improper fixing of knives make the operation of technology less effective. The height of the cutting of the grass changes after adjusting the position of the rink or wheel located in the front or rear of the knife cylinder.
They have one knife horizontally fixed to the engine shaft. Rotations with high speed make it possible to cut off both grass and other plants. Some models have disks with replaceable plastic knives. they are easy to replace if necessary.
There are wheels in separate mowers, but most models move on air cushions. Here the engine rotates the impeller, which distillates the air masses under the hood. the lifting force is created. Metal knife is placed under the impeller.
Rotor.type mower is made up of:
If we talk about mowers on air pillows, then remote washers are installed above the knife that regulate the height of the grass mowing.
As an alternative solution, you can simply turn the disc with plastic knives to increase or decrease the height of mowing.
In all types of equipment, there can be containers for collecting herbal scraps.
Some gardeners give preference such that it cuts the grass as finely as possible and leaves trim on the lawn as mulch.
The value of emergency switches
All modern lawn mowers have safety systems that will not allow you to start work if both handles or a combination of the shutdown lever with the protective blocking button are not involved at the same time. The switch is turned off as soon as the lever is lowered.
Working with electrical engineering, you need to take care of your own safety. Refuse the use of equipment if you are very tired and cannot be careful. Before the plug in the outlet, check in what condition is the power cord, check that all the devices for protection, knives and fasteners are securely fixed. Wipe the cord completely, lay the excess near yourself along the edge of the lawn from which you will start.
Before work, check if there are any small objects (pebbles, bones) in the green zone that can ruin the knives or be thrown back with the same knives with great force. Keep the cord on your shoulder, grab the handle with two hands. In the process, make sure that the cord is always behind. Before adjusting the height of the mowing, the equipment must be disconnected from the mains.
After completing the work, pull the fork from the outlet, remove the remaining grass from the knives and the air intake grille. Wipe the body with a dry rag. With a spatula made of plastic or wood, remove the mulch from the bottom of the mower near the air cushion. At the end of the season, thoroughly clean the lawn mower thoroughly, rub the knife with an oil rag. Do not forget to lubricate the bearings and regulators. Also check the condition of the power cord: if it is strongly worn, order a replacement to be prepared for the beginning of the next season.
The most common breakdowns
Any technique sooner or later fails. It is important to know how to repair mowers, because not in all cases you need to contact the service center.
The braid does not cut the grass
In most cases, the cause is dumb or severely damaged knives. To achieve the best results, just change the knife every year. Choose a knife suitable for your model. When the knife is swept away, you can sharpen using electrofig or file. When sharpening, be sure to use goggles and gloves. Angle of sharpening on both sides. about 30 degrees.
Simple sharpening devices can be purchased in stores. Before installing them, it is necessary to turn off the mower from the network and adjust the cylinder positions in such a way as to highlight the maximum cutting gap.
In cylindrical braids, the gap between the knife and the cylinder should be less than the thickness of the sheet of paper. Some of the most modern models have built.in regulators with notches. In other cases, you will have to use keys and screwdrivers to carry out the necessary adjustments. Follow the uniformity of the gap along the entire length of the cylinder. To check the adjustment, insert a sheet of paper between the cylinder and a knife, slowly rotating with your hand. Gradually adjust on both sides until the paper begins to cut purely at each point of a motionless knife.
How To Fix a Lawn Mower That Quits, Dies or Stalls After 2 Minutes
It is difficult to move the mower
- When the mower hardly moves along the lawn, you may try to remove too high grass and you will have to adjust the level of mowing. When seizing rollers or wheels, they need to be inspected to make sure that there are no scraps of grass and garbage. Most likely, they need to be removed and cleaned.
- If an interference for air is formed, then the lifting force will decrease on the mowing air pillow, and it will become difficult to move it. Air lack leads to overheating of the engine. Disconnect the power and remove the remaining grass from the air intake grilles.
The technique does not turn on at all
Long and wet grass can easily block the knives. Pull the fork from the mains and with the help of a wooden object rotate the cylinder to the other side of the knife until the movement becomes free. For gasoline mowers, this technique cannot be used.
A belt that provides the operation of cylindrical lawn mowers, wears out, stretches and can break through. Remove the belt cover and check, there was a gap or belt just jumped off. Unscrew the mounting screws and move the small leading pulley to a large cylinder pulley. Put on a new belt on a small pulley and slowly rotate the big one, gradually putting a belt on it. Push the pulley to the side to stretch the belt, then tighten the screws.
Before installing the lid, be sure to check the belt tension. the degree of bending should not exceed 4 mm (the indicator may fluctuate slightly depending on the model, detailed information is contained in the user guide).
Gap in the cord
With every use, you unfold, move and turn the cord. This can lead to a break in the internal conductors. For many models, the cord is connected to the screw terminals, which makes it possible to quickly check it and replace it. If double isolation, a two.core cord is connected.
Other models use clamping contacts that facilitate the replacement. Disconnect the power, separate the plastic cover. When you unscrew the clamping bar, pay attention to the connection of the cord to the switch to comply with the polarity of the connection (wire color).
In order to disconnect the cord, insert the hexagonal key into each of the holes in which the conductors are placed. to free the clamp and the conductor. Check where the gap has formed.
If necessary, connect a new cord: twist together all individual wiring of each core, then insert the twisted ends into the corresponding terminals. Pull slightly to check the connection. Then install the clamping bar, the cord bushing and the circuit breaker cover.
Repair of the lawn mower. (changed, added).
So, dragged a benzo-cos, with symptoms: grasps but does not work.They pulled, her seals for about an hour. I say: Well, if, the maximum of the 5th time did not start, then the matter is clearly not in Babin, rather in the gasket.))).Sent deer behind beer. He said the repair price, they were compiled, although they twisted with nozzles for a long time))).
So. Disassembled. He made the Rotor’s shooter. Why do you need the Rotor’s shooter, but at least in order to remove the rotor normally. Those who write from “” Bat and nah shooter, I do not advise doing this: break the case, or the rotor will crack, bite the tsapfu or kill the tsapt carvings to death))).The procedure for detecting malfunctions in any benzoca or chainsaw:. check whether the spark is present. Should be strong and with smooth scrolling by the starter. If there is no spark, check the wires (on \ off), the candle itself and of course the short circuit itself. Often, due to broken bearings, the magnetic part of the coil sensor clings the rotor. When installing the ignition coil back, between the rotor and the coil magnet, put a piece of strip with a cut plastic bottle (to hold the gap), it should be in the rayon from 0.8 to 1 mm. But again, you need to look so that it does not catch the sensor. If even with a 1mm gap there is a shorting, then we change the bearings or the rotor itself (maybe a curve).Further, if the candle is constantly wet, this says that the carburetor shimmers! It is not advisable to climb into it (without knowledge). Everything is very fragile there and you can finally break firewood. It is better to replace with a new.
Do not start, grasps: often air leaks! We look at the intake pipe, he has it, almost from plastic! He is spinning over time, he cracks. Also pay attention to the integrity of the gasket, filter and the container itself, the case (there may be cracks).But the most common cause is the wear of the seals! It is not difficult to check: there will always be oil leak or finally everything in oil as in the photo above! You can check (whoever has a compressor) shut up the intake \ graduation channels to pass by spraying the seals with a soap solution and supply compressed air to the crankcase.You can change the oil seals without disassembling the housing, just lift the old special-hard-hardened or stiff bent wire.Do not score a new one, do not shove a screwdriver, or God forbid the sledgehammer. Having smeared the outer edge with a sealant with a slight effort, he must go. If we are tightly selected by the appropriate mandrel and with light blows in the area of the metal clip, we sit in the place.Well, since they removed it, it is advisable to check the backlash of the bearings.If you removed the crankshaft, it is also not cost.effective to change the bearings on it! Better to change everything assembly! And save your nerves and a mower)))).If the mower is weakly drawn (does not have a power), it is advisable to look into the piston. To remove the piston, you need a specification (long hexagonal screwdrivers).Look like that’s it. Who does not know what, we will not be shy.In the course of disassembly, a flaw was revealed, namely a broken oil seal (punched through).The seals were replaced. Installed on additional sealant (window, very expensive and reliable). All gaskets are replaced.All threaded joints “sat down” on anaerobic sealant (Loquetay is popularly) blue.Everything was adjusted and wound up.And people already wanted to throw out))).Do not lose hope))).Good luck and good.
The lawn mower does not collect grass
The reason for this may be faulty or stupid knives. In order to avoid such a situation, you need to install new knives every season. You can do with the sharpening of knives at an angle of 30 °.
When hidden, it is necessary to protect yourself with special glasses and protective gloves. After sharpening, you need to test the balancing of the knives.
If a cylindrical mower does not collect grass, then it is better to sharpen knives in the service center. But you can purchase a sharpening device in the store and sharpen yourself, as shown in the video. To do this, you need to bring the cylinder of the turned off the braid to the position with the maximum interval between the blades. Then the abrasive strip is glued to the sharpening device, and the cylinder is transferred to the position in which the blades relate to the abrasive. The mitch needs to be turned on for short intervals of time until the blades become sharp.
The knives are incorrectly adjusted
This can be seen on the uneven surface of the lawn. Before adjustment, it is necessary to turn off the lawn mower from the network and put on protective gloves.
The gap between the cylinder and knives should be uniform in all areas and not exceed the thickness of the office paper sheet. Even to regulate the gaps, the same paper is used. It is inserted between the cylinder and the knife, after which the drum rotates. It is necessary to adjust the knives until the paper is cut smoothly anywhere in the knife.
Having familiarized yourself with the information, we can conclude that with proper work with garden equipment and timely maintenance, most problems can be avoided. If the nuisance has nevertheless happened and the lawn mower does not work at full capacity, you can try to eliminate the breakdown on your own or contact the service center.
