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.
Electric Strimmer Repair. Makita DUR181 Electric Motor Replacement. Whipper Snipper, Trimmer, Repair
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 repeated 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 engine replacement on the lawn mower with a more powerful.
About five years ago I got an old lawn mower from a neighbor. He complained about problems with the motor, and the fact that he developed his resource. I plunged it a little and after which he worked for four years lifting oil. And last summer the engine ordered to live long. The attempt to repair it has ended in failure. There were no spare parts. Buying a new lawn mower for 25000r was strangled by a toad. And I decided to change the engine for a new.In one of the stores, I saw a similar engine, but the seller replied that there were many problems with the replacement, besides, the price was bitten by their price. I climbed the Internet. On the pages of the Sadovaya-Mototehnika site.ru/ found many offers of engines with a vertical shaft. I began to select the motor and contacted the seller Sergey Anatolyevich, who patiently listened to my wishes and gave some tips, which are as follows: 1. Determine the power of the motor (working volume of the cylinder). I came to the conclusion that my engine is 0.156l2. Determine the type of engine. For the lawn mower, it differs in that there is a brake, and the ignition switch associated with it. On engines for walkways, control is different. You can put it, but with a “collective farm”.3. Determine the length, diameter and shaft shape.
Determine the size of the Carter flange. (As a rule, they are the same for engines 0.140-0.170l, but I neglected it) 5. Determine the shape and distance from the gas tank to the box. (here I took a chance, there is the opportunity to file and feed) unfortunately the 0.156l engine was not on sale, and I did not want to buy less power, t.to. You have to mow in a large area, where not only grass, but also a shrub. Therefore, we stopped at the Champion G170-1VK engine Vertical shaft (5.5 liters.With.). In the option for the lawn mower. Sergei Anatolyevich checked everything, the goods were paid and sent to the Code of TC “SDEK” and three days later I received it in complete completeness at the terminal of SDEK. 7400r. per engine (a discount was operating); 500r. delivery to the NECK; 581p. TC for delivery to the terminal.
The installation of the installation had to be removed from the box and adjusted it by Richtezing (dented everything that interfered), in the area of the oil neck
and in the area of the throttle control mechanism
After that, the engine was screwed to the box with 4 M8 bolts, while 3 holes in the box coincided without problems, and the 4th had to be drilled.And after painting and drying the box, a new motor was installed on it.
The lawn mower was covered by three kilograms, so I had to strengthen the handle, welding the lining at the place of attaching it to the box. I also had to make a new hole to shorten the handle, since the “brake” cable turned out to be short.
I had to transfer the stop of the cable shell.
The knife was attached by a bolt of M8, the veneer used the old one, undermining it by about 0.5mm
Successful tests were successful, but then I found fuel flow. Turned out to be weak Chinese spring clamp. I had to replace with a simple.Well, such a mower turned out.
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 braids 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.
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 main malfunctions of the lawn mower
Рассмотрим основные виды неисправностей газонокосилок Makita, причины их возникновения, а также способы устранения.
- The device is rattling and issues an unusual roar to it. These sounds, as a rule, indicate that the electric motor bolts are weakened, or the device case is poorly fixed. To fix this breakdown, you need to check the bolts. Revealing the backlash, just tighten the bolt denser. Due to the substantial vibration of the electric motor and corps with these problems, the owners of the lawn mowers often face.
- In the process, a strong vibration of the device is felt. The most common causes of this are the weak mowing mechanism located on the shaft of the electric motor, or the breakdown of the mowing knife. The repair is limited to tightening the bolts. In case of damage to the knives, they need to be replaced or sharpened.
- The device unevenly cuts grass. The reason for this may turn out to be that the knives are dull. Knives should be sharpened or replaced.
- During the operation of the device, the front wheel drive stops. The reason is in the strong deterioration of a drive belt, which must be replaced. Perhaps the clutch cable is stretched: then it is necessary to adjust it.
- During the operation of the device, its engine stops immediately after turning on. This happens when the crankshaft or piston is seized. Sometimes the reason is that there is no oil in the crankcase. Check if there are oil, or give the cornering parts manually, but the best solution is to contact the service center.
- The engine engine does not turn on. This malfunction can have many different reasons, more of them will require qualified assistance to the service center specialists. The most common of them are a cable break (in electrical devices), the refusal of the power supply or the discharge of batteries (in battery lawn mowers).
