The electric mower is buzzing and does not spin. Cylindrical lawn mowers

The knife stopped rotating the Elitech electric. What can be done?

The knife stopped rotating when I tried to manually move with a knife-you feel some kind of pull, moves hard, the power is not enough to move the knife. Before that, there was the same problem, then I opened. there the belt flew and broke off, I ordered a new one and changed. Now I thought that the belt is also, but no with the belt, the electricity is supplied, I cleaned everything. What could it be? Thanks in advance!

Irina, I would determine the cause, first I removed the belt. Then I tried with my hands to scroll the engine and an intermediate shaft with a knife behind the pulleys. Some of them will spin with difficulty. Most likely the bearings are to blame. May need lubrication, or maybe replacement.

Thank you, Alexander, I will see, maybe the truth of the bearings, I will unsubscribe.So pleased with her, about eight years old, thanks

There can be three reasons. engine, gearbox, bearings. Eight years. a record period for the budget unit. In the engine, the insulation of windings could be violated and it does not develop power. The bearings could fly. And there is a gearbox? How often they added grease there. Must watch. But in any case, you need to thank the Chinese comrades that the device has lived for eight years. Good luck.

Vasily, I think that your answer is not entirely accurate. Firstly, there are no belt transmission and gearbox on such units at the same time. And Irina writes about the belt. Secondly, if there was a violation of isolation, then it would lead to a breakdown and the inter.flip circuit. And this is a crack from sparks, the smell of burning insulation and overheating. Irina did not write anything about this and the replacement of the engine does not threaten her. On my lawn mower I had to change the bearings after 4 years. Also began to spin hard, but also a nasty screech was heard as soon as it worked a bit and the bearings are heated. At first, I was there to the fact that a little vigor dripped on the upper bearing. But as soon as I felt that this does not help very much, I replaced both bearings without waiting for it to jam and break the landing nests.

Good afternoon, Irina! According to the description of the situation, it is more similar to destruction/jamming of the bearing. But a more accurate diagnosis can only be obtained after opening.

The unit does not turn on

In this situation, there may be 2 options: a light bulb that means the readiness of the unit to work, can be caught or not. Depending on this, the algorithm for diagnosis of the breakdown will differ.

The bulb does not burn

If, after the device is turned on, the bulb located on its case does not light up in the outlet, and it does not start, then, first of all, it is necessary to check if there is a voltage in the outlet. It is done simply: take any electrical appliance and include in this outlet. If the device has earned, then you need to look for a malfunction in an electric fork and cord.

To check the fork, spin it and check the reliability of the connection of the wires to the terminals. To check the cable, it is necessary to disconnect it from the contact pad of the device and “call” the tester. If a cliff is detected in the cable veins, it should be replaced.

The bulb is on fire

The reason for this behavior of the unit, when the indicator bulb burns, but the fan does not work and no sounds can be heard, it can be caused by the blocking of the block with the buttons. To check the buttons, you need to disassemble the button unit located on the floor fan stance or stand near the desktop. But, before disassemble the device, make sure that it is turned off out of the outlet.

The work of buttons is very simple: there is a “vkl” and “off” position. Using the tester, check the “output” and “input” on each key.

If a faulty button is detected, it will not work to repair it. Therefore, the switch should be replaced or the connection is directly. This approach to solving the problem will help start the unit into work if you are far from the store, for example, in the country.

Faulty speed switches can also cause why the fan does not turn on. To check the regulator, you will need to put it in the maximum position and check the “entrance” and “output” using the same tester.

Cooler’s blades are poorly rotated

In the case when the fan does not pull and poorly drives the air, you will need to disassemble the case in which the motor is located. Sometimes the fact that the propeller does not spin can signal the lubrication insufficiency in the sliding bearing installed in the electric motor.

Dismantling the fan is as follows.

• First you need to unscrew the protective grid (its front part) and remove it.
• After the grid, disconnect the propeller. He can be screwed to the shaft of the motor with a nut with left thread. That is, to unscrew the nut, rotate it clockwise, and for its twisting it is counterclockwise.
• Remove the rear protective net by unscrewing another nut.
• Unscrew all the fasteners holding the casing of the unit. Sometimes in the handle to adjust the rotation of the case there is another bolt. If it is not unscrewed, it will not work to remove the motor casing.
• Now, the engine is open, drip a few drops of machine oil (it is better to use spindle oil) on the sleeve (indicated by the red arrow) and turn the shaft several times in different directions so that the lubricant is absorbed inside.
• After this procedure, a slight rotation of the shaft resumes. Collect the motor body in the reverse order.
• Turn on the unit and check the air flow strength.

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.

Search for a malfunction

The external inspection of the contacts of the connectors and windings of the electric motor did not reveal deviations. The electrical diagram of the lawn mower can be checked and you can check it using a multimeter. Measuring the resistance of the windings with a multimeter included in the resistance measurement mode did not reveal their cliff or short circuit.

A segment of the cable that goes from the switch to the engine was also checked. When connecting an ohmmeter to its ends and intensive bending, the resistance did not change and was zero. It became obvious that the malfunction is in the junction unit, which was to disassemble.

Many manufacturers of electrical devices to exclude the possibility of independent repair during assembly use screws that can only be tightened. The supporting plane of the beam towards the unscrewing is made at an oblique angle and the screwdriver cannot catch.

In addition, the head of the screw has a slot under a trihedral screwdriver, which in the standard sets of bit I have not met. But this obstacle is easy to get around if you heat the screw using a soldering iron or emitting a suction of a self.tapping screw using a drill and a drill rotating counterclockwise.

The screw warmed up to the softening point of the plastic is easily unscrewed by the sting of a flat screwdriver selected. By the way, you can also unscrew the strongly rusted and cloudy screws and screws. I had to do this more than once when repairing electric kettle. When assembling I replace exclusive screws with self.tapping screws, with a standard head.

The switch cover still holds on two snapping latches, which must be taken to the side through the existing slots in the housing. The location of the latch is shown by arrows.

The main problems with gasoline machines

Primary diagnosis is carried out from the stage of elimination of the most obvious breakdowns. When the motor does not start, it is worth monitoring the presence of fuel in the tank. If there are its remnants from last season, then it is worth replacing it. Low.quality gasoline after wintering is able to lose its characteristics, give an undesirable sediment or even stratifying at a fraction in density. In this form, he is not able to start the engine, but only clogs the system.

At the second stage, we find out why the spark does not appear. Its loss will not make it possible to ignite the fuel. Remove the cap from the candle and unscrew it from the planting nest by a special clip that came with a mower. Next, we throw the cap to the candle, bring it closer to the threaded part or the metal element of the motor, and at this time the partner pulls the starter.

With such manipulations, a blue powerful spark is required to appear in the working node. She will be able to notice her even in daylight. It is important to test this next to the unpainted metal part of the engine that can conduct current.

When there is no spark, you need to go for a new candle to the store. Do not return to the motor even with a weak or unstable spark. It is better to clean the working contacts from the haze on the head.

During operation, the occurrence of rattling in the design is possible. It at first does not affect the performance of the mechanism as a whole. However, it can lead to unbalancing and increased noise during operation. It is worth tightening the fasteners on the frame in a timely manner.

Tightening fasteners on the frame

An uneven slice of grass is evidence that you need to sharpen a lawn mowing knife. It’s not so difficult to get to them, but it is important to completely turn off the equipment from power. You can work on your own using tisses and files or on a solid sandpaper. It is important to ensure the cut angle uniform throughout the line 30 degrees. If there are excellent sections in the surface, then this is evidence of getting on a solid surface. Replacing them will cost quite expensive.

After turning on, a whistling sound appears. An unpleasant acoustic effect is associated with the penetration of foreign elements inside the design. They can block the video in the aerator. You can solve the problem with disconnecting a blocked roller and subsequent extraction of an extraneous subject.

The engine of gasoline equipment becomes almost immediately after the start of short operation. The culprits are a jammed crankshaft or a piston. In parallel, we check the presence of oil in the crankcase. On the disconnected engine, manually start the rotation or add the oil as necessary. However, in such a situation, you often have to apply for recovery to specialists.

Problematic issues with a carburetor and fuel system

Before starting repairing the engine of the lawn mower, it is worth checking if the pistons lay down. To do this, it is necessary to dismantle the motor. We also remove the carburetor from the structure and conduct visual control for the availability of possible defects. Usually in disassembly you will need a special Torex screwdriver with nozzles.

Combined Torex reverse screwdriver with nozzles

We inspect the gaskets for the identification of ruptures or burning. If one is found, then you need to ensure the tightness of the structure, replacing them with new. The air damper may contain a layer of soot, which reduces the quality of the fuel mixture. You need to get rid of the cleaning of the carburetor by raining the node in the solvent or kerosene.

Sloving during operation or the absence of a set of them to enter the operating mode together with the overheating of the power unit are the causes of such events:

• Idle adjustment violation. You can unscrew the nozzles yourself with a screwdriver into the right position. It will be possible to do this even by ear, so that the motor works smoothly. No need to shoot knives, but they should not rotate.
• There is an air filter pollution. It is enough to extract it out and clean, rinse. We dry in natural conditions in the wind, without putting a stove or fireplace.

Air filter casing is removed with a flat screwdriver

After removing the cover, the air hose is also carefully removed

Remove the lid of the fuel chamber of the carburetor and clean it. An ordinary Weadshka is quite suitable for this, but you can buy a special liquid

To clean the fuel chamber, first wipe it WD-40, then soak mines at 15-20, wiped again. So you need to repeat 3-4 times to completely clean the camera and channels

After purging, the carburetor is assembled and returned to its place

The clog of exhaust leads to a narrowing of the output flow of the exhaust pipe. Resins appear on the inner surface due to the incorrect ratio in the composition of the fuel mixture and oil. We twist the crankshaft so that the piston comes out to the maximum up and clean its surface with a wooden stick.

In more serious cases, it is recommended to contact the warranty service. Otherwise, unprofessionalism will bring more breakdowns. over, with independent search for a malfunction and repair during the warranty period, the guarantee ceases to.

The lawn mower is buzzing but the knife does not spin

Repair of the lawn mower is carried out taking into account the mechanism of operation and the prerequisites for the breakdown of the unit. often the device fails 3-4 years after active operation.

Repair of lawn mowers is needed in subsequent cases:

The causes of the malfunction

The prerequisites for the failure of the lawn mower:

In the first case, you will need to change the case, handles, knives and wheels for lawn mowers. When blocking the knives, an mechanical stop of the unit occurs. Such a breakdown is associated with an attempt to mow hard or high grass. Repair of a mower consists in freeing the cylinder from stuck grass and scrolling it in the other direction.

When operating, a lawn mower with a blunt or crumpled knife, the grass is mowed uneven. With all this, the device can vibrate or brake sharply.

In order for the device to work properly, it is recommended to sharpen the knives with a ratfoll (angle of 30 °). In an unpleasant case, an abrasive tape is used. The gap should be between 2 blades, touching the strip. The device cuts off periodically (15 seconds). If the knives are sharp, then the strip is removed, the gap is regulated.

At the wrong position of the knives, the cylindrical lawn mower makes sharp and uncontrollable movements. Normally, the size of the gap between the cutting elements should be thinner than the sheet of paper. The motor is good at well, but the knife does not twist. But nothing helped, the motor is spinning, and the knife. In an unpleasant case, the gap is adjusted. The engine is buzzing but it is not clear how it works. But they say that they were allowed from it 2 kW. For earlier it is recommended to study the device annotation, pull the fork out of the outlet. With a cracked connection, a whistle occurs. The device vibrates and rattles. Under the repair of the lawn mower, it is planned to adjust the bolt joints.

If the belt breaks 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. The brand new detail is put on a small one, and then on a large pulley. The gear is fraught in its original position. The next step is to check the stretch of the new belt. The deflection should not exceed 4 mm.

A malfunction of electrical models

The prerequisites for a sudden disconnection of an electronic lawn mower are associated with a cliff of the cord or the absence of current. In the first case, it is recommended to check the cable for a cliff. To change the power cord, you will need to pull out the plug out of the outlet, open and dismantle the circuit lid.

Before unscrewing the clutch of the cable bar? You need to understand the diagram of its connection to the switch. To disconnect the cord, a hexagon is used (1 mm dialect). The electric motor is buzzing, but does not twist. But the knife does not spin. The lawn mower turns on. The clip is released, the conductors are dismantled. To check the cable for a cliff, multimeter is used. A new cord is installed as needed. With all this, a revolutionary sequence is observed.

In the second case, it is recommended to connect another device to the mains. Electric devices may not work when the fuse is damaged in the fork. To carry out repair work, you will need to disassemble the fork. For this, a screwdriver and a tester are used.

Motor malfunctions occur when overheating of the lawn mower:

In the first case, it is recommended to wait a few minutes so that the motor cools. In the second case, you need to remove the stuck object. The effectiveness of the cooling system depends on the state of the air filter. Dirty device poorly passes air, which helps to turn off the device. Experts advise cleaning and changing the filter once every 3 months (with constant operation of the lawn mower). With a breakdown of the electric motor, the corresponding smell and noise appear. In this case, you need to replace the drive.

Motor breakdown

The design of a gasoline lawn mower, unlike an electric counterpart, is more complicated. In some cases, the unit cannot be repaired. If the engine does not start or stop immediately, then it is recommended to check the ignition. This will need to be dismantled. Dry candle indicates problems in the feed system, and wet. on the carburetor. In such cases, repair work is carried out by professionals.

If there is a black fog on the candle, then it is replaced. In this case, the reason for the breakdown of the lawn mower is not taken into account (setting the carburetor, poor.quality fuel). The engine is buzzing but does not rotate. forum about radio. Often in gasoline models, the fuel hose clogs. If gasoline does not flow, then the saloon is cleaned with a needle, and the fuel filter is replaced by a new analogue.

If the lawn mower does not mow grass, then the knives are checked. If necessary, they are replaced with new cutting elements or Nat. In the second case, it is recommended to use protective glasses and thick gloves. You can drag the braid knives using special devices included in the set of the device.

If the knives are blocked by long grass, then it is recommended to turn off the lawn mower. A cylinder (in the other direction) to its free rotation scrolls with a wooden stick. If the lawn mower does not work as a result of a circuit breaker malfunction, then it is recommended to check it and replace it with a working analogue.

In the absence of voltage in the outlet, the shield is checked. Some devices are equipped with thermal protection. When such a system is triggered, ventilation grilles for pollution are checked. A soft brush is used to clean them.

Conclusion

Repair of mechanical braids is carried out when the cutting elements are blown up or damaged. In this case, experts recommend to independently dismantle removable knives. Evadal is used to sharpen them. If necessary, the battery is replaced in battery.

Carrying out repair of electric municipal mowers of electric ones: we set out all the nuances

Lugus maintenance and repair can be carried out with your own hands and at home. Naturally, the implementation of such works has its own characteristics. It is worth taking into account the need for appropriate knowledge, skills and tools.

Types of malfunctions of electric mowels

It is not difficult to repair the dull knives on their own, since they are removable and they can be sharpened with an ordinary emery, withstanding the sharpening angle of 30 degrees. In case of malfunctions of other details, t.e. hulls, wheels, handles, they will also need repair or replacement.

In the battery devices to this problem, the battery fails is added. It is more difficult to cope with the repair of a lawn mower equipped with a motor, t.e. gasoline and electrode.In the first case, the problem of overheating and overload is added to possible breakdowns, as well as malfunctions in the oil and fuel supply circuit. In electrical breakdown, it can also be caused by overheating or overload, since not all models are equipped with protection.

The process of diagnosis and restoration of the cutting part

• Drain the oil before removing the knives.
• Disable electrical devices from the network, and on gasoline units turn on the lock.
• Completely drain the fuel and remove the spark plug.
• Install the lawn mower on a support that promotes convenient repair.

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.

Brand break

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.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration. The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.

Replacing the lubrication of the hard shaft is as follows:

• Apply a small amount of lubrication to the shaft and evenly smear it along the entire length of the part, including the slots at the ends of the rod (if they worked, the shaft will have to be replaced);
• After lubrication, insert the shaft back into the bar and put the gearbox in the same place.

The lubrication of the flexible shaft is as follows:

• unscrew and remove the mowing head;
• remove the bar from the electric motor by unscrewing a couple of bolts;
• Pull out a flexible cable from the bar;
• Lubricate the cable with grease along the entire length.

This is done like this: first you need to lubricate the end of the cable, and then insert it into the bar, after which, as it moves into the pipe, you should apply grease to the part and evenly distribute it on the surface. Then insert a bar with a flexible shaft into an electric engine and fix it.

In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.

The trimmer for the grass is very hot

Overheating of a trimmer for grass can occur for many reasons:

• Gasoline has not the same octane number indicated in the instructions for the unit;
• the proportions of gasoline and oil during the preparation of the fuel mixture are not observed;
• A mixture of fuel with butter has long been prepared (the mixture cannot be stored for more than 2 weeks);
• The trimmer for the grass works more than the time instructions;
• A low.power trimmer for grass on thick and hard grass is used, the device works with overload and quickly heats up;
• shifted towards the bar or the cassette lid clutched.

The latter occurs if you install a mowing head inappropriate for this unit, or when the axis shifts inside the bar. These changes make it difficult to rotate, the load on the engine increases, and it overheating.

Repair of an unexpectedly stopped electric engine

If the motor worked, but suddenly stalled, you need to check the crankshaft and the piston. perhaps they were overwhelmed. This is due to the absence of oil in the crankcase. It is better to contact specialists with this breakdown, as in the case when the electric motor of the lawn mower requires repair.

For non.precise operations of the lawn mower, the owner must conduct its regular maintenance after the end of the working season, t.e. Before her premises for winter storage. This will cost cheaper than repair or buying a new electrical device.

Among the main measures that ensure the reliable operation of an electric mower is clean. The mowed grass accumulated under the neckline causes erosion of metal parts. The compressor or blunting will help to remove the remaining weeds.

The electric motor of the mowing is air cooling, therefore, it also requires a cleanliness that is a key to effective functioning. Suitable for cleaning the cooling ribs soft brush and compressed air.

Timely oil replacement specified in the use guide will become the key to prolonged trouble.free work, as well as the periodic cleansing of the air filter.

In the presence of a certain experience, it is easy to repair the lawn mowers with your own hands. The video below will help in this.

Safety precautions when working with a gasoline mowing

Each manufacturer in the operating instructions for its lawn mower describes in detail how to turn it on, what can and what can not be done with this device in order to avoid injuries or breakdowns.

The basic safety rules when working with lawnmands are the same as using another motorized garden technique, that is:

• It is impossible to neglect daily inspection and timely maintenance, because this will lead to a decrease in the resource of parts and aggregates of the lawn mower.
• You can not serve the device or mow grass after taking alcohol, drugs and any substances affecting the reaction rate, balance and adequacy.
• Children cannot be allowed to work with a mowing without adult supervision.
• It is undesirable to use the apparatus for mowing grass, the height of which is more than 5 times higher than the maximum mowing height, for such vegetation it is necessary to take either a special lawn mower or use a trimmer for grass.
• It is undesirable to use the lawn mower in cluttered areas due to the high probability of a knife impact on a solid obstacle.
• You can not turn or tilt the mower to a complete stop of the knives.
• You can not smoke or use open fire during service or refueling the device.

Device

All electric lawns are arranged the same. They have a platform for mounting a motor whose shaft is parallel to the ground. A knife (or two) is fixed on the shaft of the electrical device, with which weeds mush. To make the mowing high.quality, the speed of the cutting electrical tool should be high.

The platform itself for convenience is supplied with four wheels and a handle with the elements mounted on it that control the engine. It is designed to push the device forward and control an electric mower.

Wheel fastening can be stiff and be rotary. In the first case, you will have to raise two wheels in the corners. Rotary ones provide for the use of lower physical strength.

In addition, they “spoil” the lawn less. Therefore, if flowers are planted on the lawn, there are swings, arbors, etc.D., it is recommended to use rotary wheels. Electric lawns with such wheels are convenient for caring for areas under shrubs and trees.

The engine is closed by a case that simultaneously protects from injury by random objects of an operator working with an electric lawn mower. The material used for its manufacture is more often plastic and less often. metal. As you can see, the device of the electric municipal mower of the electric is quite simple.
