Lugging a lawn mower

Lawn mower. a productive machine designed to care for the site. The tool carefully cuts the grass, forming a neat, beautiful lawn. The garden machine is bought for more than one year. To maintain the performance and full functionality of the lawn mower, it is necessary to provide them with competent maintenance and quality care. It is important to monitor the condition of the cutting elements, engine.

A set of measures for maintenance depends on the type of tool, frequency of use, intensity of operation. Consider how to properly care for gasoline and electric lawners, which nodes and mechanisms to pay special attention to.

Barrow care

Gasoline lawn mowers are equipped with internal combustion engines. Motors of this type are quite demanding on maintenance. A set of measures for caring for a power unit is aimed at slowing the wear of components, increasing their service life, protection against breakdowns.

  • Using high.quality oil. The engine of the lawn mower needs constant lubrication. With a lack of lubricant, the motor begins to overheat, the wear of the rubbing parts is intensified.
  • Fuel drain after completion of work. When sending a tool for storage, do not leave gasoline in its fuel tank. The combustible mixture will still lose its properties and will not be suitable for use. The presence of fuel in the tank increases the risk of fire and reduces the safety of the operation of a garden machine.
  • Replacing filter elements and hoses. Fuel hoses and filters are polluted by extraneous impurities, which leads to a deterioration in their performance. They need to be cleaned regularly. For cleaning, it is recommended to use compressed air and gasoline. If the filters and hoses are very contaminated, it is better to replace them.
  • Replacing elements of the cutting mechanism. Knives should be sharp enough to quickly and effectively mow grass. If they are dull, it is necessary to remove and sharpen, level the edges of the blades or install a new cutting element.
  • Replacing belts. The belt drive is responsible for the transmission of the rotational moment. Over time, the belt wears out, becomes thinner. His gap can lead to complex breakdowns. To prevent this, regularly change the belt and tension videos.
  • Tighten the fasteners. The work of the tool is accompanied by vibration. Over time, it can intensify, uncharacteristic creaks appear. As a rule, this happens 1-2 years after buying a car. The reason is the weakening of fasteners. To eliminate the problem, just tighten the bolts. You can do this using the head or key of the corresponding size.

The tool of the tool also needs to be inspected regularly. Metal membranes are subject to corrosion. If you notice the lesion of the lesion, remove the rust, treat the problem space with a special anti.corrosion composition and cover with paint.

Repair of the lawn mower

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

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

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

does, lawn, mower, electric

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

Dismantling the lawn mower

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

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

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

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

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

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

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

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

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

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

An important first launch

One of the main differences in electric lawn mowers and gasoline is in the simplicity of launch. They do not need to be refueled, configure. Just include on the network, install the mowing height and go for a walk on the lawn. Your main task at the first launch is to master the management of the tool. Sometimes this is problematic even for electrical models. But the control of the Advancedrotak 660 lawn mower by Bosch intuitively is absolutely clear, so you can easily master the work on it. And for women Advancedrotak 660 is just a find. Remember how many times the flowers and decorative shrubs have been mowed, which the husband did not know about? With Advancedrotak 660 and plant, and you can mow yourself, carefully bypassing all the inconspicuous, but such expensive plantings to the heart. In this case, you do not need to mess with gasoline, delve into technical subtleties and strain physically.

Almost any family member can use the ADVANCEDROTAK 660 mower. Photo by Bosch

How to mow right so as not to harm the lawn

There are 3 basic rules of the mowing that need to be strictly observed if you want to get a beautiful, soft lawn.

You need to observe the height of the mowing

Many summer residents, especially those who appear on their possessions with rare raids, are used to mowing grass almost under the root, even despite the fact that it was originally a decent height. Remember: at a time it is permissible to mow no more than 1/3 of the height of the grass! If the lawn is too short, it can start to hurt, exposing the earth. In addition, instead of a soft coating, you get dry and stinging grass.

Launched lawn must be mowed in several suits. True, in this case it is necessary to adjust the height of the knives several times, and this is not all mowers as simple as we would like. We’ll have to go, look for tools, twist Time is coming, the mood is changing, working everyday life is nearing. The owners of the ADVANCEDROTAK 660 lawn mower by Bosch have no such problems. The height of the nobility in the range from 20 to 80 mm is regulated by one movement. Just click on the button. and the tool is ready to work with a given knife height. A delicate mowing will benefit the grass, it will begin to bother, forming a dense, soft coating.

You can not leave mowed grass on the lawn

This is good fertilizer, but not for the lawn! Large mowed grass will begin to rot, and under it will begin to prete and lawn. As a result, voids will appear on it. Therefore, everything that was squinted needs to be removed. You can work with a rake, but it is much easier and faster to use a mower with a grass collector.

Bosch made sure that you did not waste time collecting grass. Advancedrotak 660 is equipped with a folding grass collector for 50 liters. This means that the grass immediately gathers in the capacity of the optimal volume, and you do not have to constantly stop to clean the container. You can store the grass collector in a folded state, which saves a lot of space in the household. The lawn after work is fresh and clean, and everything that was mowed easily convey to the compost heap.

The blade should always be sharp!

Otherwise, it will not cut, but to tear the grass, and you will get yellowed and dried sections. Advancedrotak 660 braid is equipped with a special.shaped leafcollect knife made of hardened polished steel. This provides high.quality mowing of grass at any time of the year: in the spring, summer, autumn.

Thanks to the development of Leafcollect, Bosch Lawn mowing can collect fallen leaves! The knife grinds them and sends them to the grass collector. You get a clean section and healthy material for compost. And all this. without exhausting physical work!

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.

How to Make a Remote Control Lawn Mower at Home

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.

How to care for a lawn mower, recommendations for servicing lawn mowers

A good owner will always take care of garden tools because he remembers: they need to care for all year round. There are tools that you use only a few months a year. For example, a lawn mower. And so that she serves you as long as possible, you need to take care of it even in winter.

The story of how to care for the lawn mower is worth it, perhaps, starting with what lawn mowers are. Modern units can be divided into two large groups. electric lawns and gasoline. First, consider the general recommendations that are suitable for both types of lawn mowers.

  • If you use the lawn mower more than 4 times a month, you need to drag the blade at least once a month. This is explained by many reasons: for example, a blunt blade mophes the lawn unevenly, and this is very harmful to plants. If your goal is to achieve a beautiful even lawn, you just need to monitor the sharpness of the blades. In addition, this is also important for considerations of savings: a lawn mower operating with a dumb blade will use fuel or electricity up to 20 % more than a lawn mower with a sharp blade. By the way, you will have to spend money not only on fuel, because with a blunt blade he will occupy more time and mowing itself.
  • If scratches and deformations appear on the blades, then buy a new one without putting it in a long box. The smoothness of the blades is no less important than. Knives for lawn mowers.
  • After sharpening, fix the blade as hard as possible. The same applies to the new blade. Please note: the ends of the blade should be turned down to the ground. If the shape of the blade is twisted, make sure that the acute side is turned down.
  • After each mowing, wait for the engine to cool, clean the lawn mower from plant residues. A vegetable garbage clings to the lower part of the lawn mower next to the blade, which must be removed. This is important, since the remains of grass under the body or on air intakes can become source of fire. Do not use chemicals for cleaning (in t. h. gasoline or solvents): they destroy the parts of the lawn mower.
  • If the lawn mower is working without a herbal collector, leave the valve ajar to avoid overheating of the motor.

Let’s talk more about gasoline lawners. They have a number of advantages: more mobile than electric, powerful, ideal for processing large areas.

Husqvarna gasoline law mmores have proven themselves perfectly, with a large haircut width and comfortable handles. A popular model of lawnmands of this company can be, for example, the Husqvarna LC140S model.

In general, it can be argued that gasoline lawn mowers are more whimsical than electric. This is due to the very specifics of the unit. Starting the new season, you need:

  • change oil in a mower (exception. two.tint engines);
  • change the spark plugs (as a rule, it is enough to do this exactly once a year);
  • Replace the fuel filter and air filter;
  • Before starting the engine running.

When cleaning the lawn mower for storage, drain the remaining fuel, after turning off the spark plugs. After the fuel is merged, turn on the lawn mower and work out the remaining fuel.

Let us now turn to electric lawnmands. They are lighter, but less mobile, it is convenient to use them in small areas where there is a close electrical network.

Here, care rules are also dictated by the very specifics of the device: caring for an electric lawn mower is mainly reduced to regularly checking the integrity of the cord and other details that can lead to injury with electric shock. It is also important that electric braids usually have a plastic decree. It needs to be cleaned after mowing especially carefully, the juice secreted by mowed grass can fall on the shaft of the knife drive. This leads to the formation of rust.


In general, electric lawns can be perfect assistants in the garden due to their low weight and maneuverability. So, the weight of the lawn mower Viking Me-235.0 is only 13 kg, and the universal lawn mower Gardena PowerMax 36 E, which can be used both for mowing and mulching, weighs 14 kg.

The most important thing is not to forget about compliance with the rules of operation, and your lawn mower will serve you for a long time!

Mowing wet grass with an electric lawn mower. why it is impossible?

Using an electric lawn mower or a trimmer for grass for mowing wet grass or raw weather is strictly not recommended. Moisture entering the device can lead to a short circuit. There is a high risk of current flow. Even if such dangerous consequences can be avoided, still mowing vegetation is an additional load on the power unit.

  • The mockery of wet grass is an emergency operating mode, the work in which accelerates the wear of components of the device.
  • Wet grass has great resistance to cutting elements, as a result of which they are blunt much faster.
  • The motor works in conditions of overload, which, of course, affects its functionality and leads to a reduction in the working resource.

Wet grass rushes to the spindle and knives, the load on the engine increases. No techniques in this case will help. Whatever schemes you use, all the same, the electric motor will suffer. And the risk of short circuit and electric shock is very high.

Wet a wet lawn haircut with a gasoline lawn mower. if there is no other way out

If you mow moist vegetation, then only a gasoline lawn. The tools are characterized by higher performance, equipped with powerful engines. Despite this, an increased load is still carried out on working mechanisms. First of all, moving elements, pistons suffer from. If there is no other way out except for the haircut with wet vegetation, use the gasoline unit carefully, every 30-40 seconds, switch to idle mode to avoid overloading the motor.

note! Due to the effects of moisture on the tool, metal parts can be damaged by corrosion.

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.

Cylindrical braids

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.
  • Switch.
  • Filter.
  • 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.
  • Rink.
  • 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.

Rotor mowers

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.

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.

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.

Let’s summarize

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.
