Lawn mowers MTD: pros and cons, varieties, choice and operation
The lawn mowers of the American brand MTD have been in demand in the garden equipment market for many decades. A variety of models in the assortment of the brand can satisfy the need for both amateurs and professionals. It is worth noting that all the wheel representatives of this brand have a well.protected chassis. Thanks to special protectors on wheels, the rest of the grass with mowing will not receive tangible damage, which is an undoubted plus and a feature of the technique of this manufacturer.
Advantages and disadvantages
Differ in the presence of ICE (internal combustion engine), which ensures high efficiency of use. Also, one of the advantages of gasoline lawners is high mobility, which allows the unit to work in conditions of limited electrical consumption. Allow you to process a large territory and have several interesting functions, for example, alignment of edges and side emission of grass. Unfortunately, the apparatus has less environmental friendliness due to fuel exhausts. Gasoline lawmakers are divided into self.propelled and non.self.propelled.
- Self.propelled. Thanks to the functions of the movement of the MTD lawn mower, herbal begging in various hilly areas, thereby increasing the effectiveness of their work, and large wheels allow the unit to move easily even in hard.to.reach places. In addition, it becomes easier for a person to use the lawn mower.
- Non.self.propelled. The main feature of non.self.propelled technology of this type is a person’s direct participation in the mowing process, which allows you to do work at its discretion. Such lawnmands, as a rule, are used in small areas where the whole process will not take much time.
Of course, the main advantages of electrical models over gasoline are high environmental friendliness. Since earlier the exhaust was indicated in the deficiencies during the combustion of gasoline, it can be said that there is simply no such lack. Also important features of such devices can be called less noise during operation, light weight. Also, you need to follow them less and you do not need to replenish the fuel.
Of the minuses, one can note less power compared to gasoline analogues, as well as low mobility. Since electricity needs electricity for these lawn moutines, a power source is needed nearby, or individual carrying must be used, which will make mowing grass more difficult.
Interesting features of the MTD brand in terms of electric lawns are protection against overheating of the engine, increased protection against debris and moisture, and thanks to the function of the “garden vacuum cleaner”, even wet grass can be removed.
Why choose electric lawners MTD?
The main reason for the choice of mowers of this brand is a combination of low price and high performance.
Therefore, they are bought by either people with low income, or those who need such a device for short.term use, so it makes no sense to take an expensive model.
The assembly quality is at a level above the average, which is also one of the reasons for choosing precisely these mowers, because most Chinese analogues of the comparable price are made much worse.
Another reason why customers choose these devices is a successful construction of the case. despite not too much weight, convenient handles facilitate the carriage or loading of equipment into a car.
The most popular models
MTD Products Inc engineers constantly improve electric lawn mowers, and also develop new models that better correspond to the expectations of most potential buyers. Therefore, there is a constant update of the model range of these devices.
Some devices are removed from production for the production of more popular models, while others modify and change their name so that potential buyers do not confuse them with the source device.
One of the most reliable signs of the popularity of a particular model is positive reviews about it, placed on one or more resources, such as:
Therefore, this article includes only those models that have positive reviews on these resources.
Smart 32 E
This is the smallest, and therefore the most maneuverable lawn mower is designed to cut small lawns with an area of 50-250 m 2.
It is equipped with a reliable asynchronous electric motor with a capacity of 1 kW, and the width of the mowing (capture) of this model is 32 cm.
The main advantage due to which this mower has gained popularity is its weight (6 kg), so even physically weak people, for example, adolescents or women will be able to control it.
Some of the users notes an extremely unsuccessful cooling system of the bearing and engine, because the flow of blowing air creates a rotating knife, and during the mowing the grass cut fragments of vegetation clog ventilation holes and the device overheatics.
This mower has a modification with a synchronous (collector) engine, as well as a more effective cooling system. Smart 32e (K).
Here are the advantages of this lawn mower:
- Thanks to the slight weight, even women will be able to independently mow the grass with this device, but also load it on their own in the car;
- Due to small dimensions, the device turned out to be very maneuverable, so it can be used to cut grass in narrow or curly areas;
- Thanks to a low cost, even families with a wealth below average can buy such a mower.
- Due to the unsuccessful engine cooling system, the device cannot be operated for a long time, so it is very important to alternate the time of operation and the rest time required to cool the engine and the bearing of the shaft;
- inconvenient engine starting lever;
- There is no mulching function.
This lawn mower was one of the most popular apparatuses in the entire line with a width of a 32 cm width, however, due to a lack of power, it was replaced by another model.
The main advantage of the device was a successful cooling system of an asynchronous engine, thanks to which it easily tolerated overloads and a long operation.
There are cases when this model has worked for more than ten years with careful use.
Here are the advantages of this device:
- High maneuverability provides comfortable work even on narrow paths or areas of complex shape;
- Thanks to an effective electric motor cooling system, the mower is 10 years or more.
- small power, which is why the device does not cope with high grass well;
- quite large weight for such power, so it will be difficult for women or elderly people to load their mower into the car on their own;
- the device is discontinued, so finding it in stores is almost impossible.
This model at the time of its appearance became one of the sales leaders thanks to a low price and a reliable synchronous motor with a good ventilation system.
Unlike most budget devices, the air for cooling the electric motor does not flow by the holes in the deck, but through the ventilation grill, so that the mowing of the grass does not affect the cooling of the motor.
However, due to a low-power engine, this device was suitable only for the mowing of well-groomed grass and with its help it was impossible to mow high vegetation.
In addition, to reduce the cost of the apparatus, the engineers abandoned the central or pile adjustment of the mowing height. to change this parameter, it is necessary to install each wheel in the corresponding hole. This greatly complicated the choice of mowing height, especially during the mowing of grass, but made a mower more affordable.
Here are the advantages of the device:
- A reliable synchronous engine has a sufficient power for mowing well.groomed and slightly neglected lawn grass;
- The well.thought.out ventilation system effectively protects the motor and bearing from overheating, and also extends their service life.
- The model has been discontinued, so it is very difficult to find in stores;
- An uncomfortable system for changing the height of the mowing does not allow you to quickly change this parameter.
3412 E HW
This model is also discontinued, but it can still be found in various stores.
Due to the fact that the mitch increased the capacity and width of the capture, it took an intermediate place between miniature apparatuses for tiny lawns and larger models for areas of several hundred parts (hundredth is 100 m 2).
In addition, engineers took into account previous models and began to sacrifice functionality in order to reduce the price, therefore they realized a centralized change in the height of the mowing. To change this parameter, it is enough to transfer the lever to the desired position, which will require only a few seconds and a small hand move.
To improve functionality, MTD engineers changed the grass collector with this mower, removing the plastic bottom and replacing it with a bag of double knitting cavalry, while the top of the container and the part adjacent to the mowing are made of plastic, so it has the necessary rigidity.
It was this grass collector, as well as a lack of engine power, have led to the fact that instead of this mower, they released a new Optima 34 E model, in which all the shortcomings were corrected.
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.
UNBOXING Lawn mower MTD Smart 46 SPBS
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:
HOW TO REPLACE THE BLADES ON A 46 INCH MTD YARD MAN 3-BLADE RIDING MOWER
- 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.
Malfunctions and repairs: how to diagnose and fix
Here is a list of the most common faults:
- The engine does not turn on or periodically.
- The knife does not rotate when the engine is turned on.
- Strong vibration of the lawn mower.
- The apparatus does not mow grass poorly.
- The engine is very hot or the smell of smoke appears.
- The self.propelled mower does not go forward well with a pressed wheel drive lever or does not go at all.
Does not turn on or periodically turns off the electric motor
The most common cause of such a malfunction is to turn off one of the forks from the corresponding outlet. This is due to the fact that they pulled the extension cable too much and he pulled out the fork from the outlet. If the motor worked and suddenly turned off for no reason, then go along the entire extension cord and check the contacts.
If all forks are inserted into the appropriate sockets, then check the voltage in the network, perhaps, together with the lawn mower, some additional electrical appliances of high power and power consumption have reached a critical value.
When this happens, fuses (traffic jams) are triggered, so you need to check them, if they are turned off, you will have to look for an additional electrical appliance, which increased the load on the intra.house network to a critical value.
If you do not turn off the device, then when turning on or long.term operation, the lawn mowers will work traffic jams that protect the home power supply from overload.
In old houses, faulty wiring gives the same effect, in which poor contacts under load heat up, which leads to:
To check such a wiring, current measuring ticks will be required.
Do not use any other measuring devices for this, because only current.measuring ticks allow you to perform such work without direct contact with electricity.
Remember. touching a bare conductor or contact, which is under voltage of 220 volts, is deadly!
First, turn off all electricity consumers, then measure the current at the entrance to the house, if the wiring is working and did not forget to turn off any electrical appliance, then the current consumption will be zero. Then connect the lawn mower and ask the assistant to start the mowing of the grass so that you can measure the current in the extension cord.
It must correspond to the power of the braid engine, which can be determined by the formula p = iu, where:
Having made sure that with mowing grass, the current consumption corresponds to the power, turn off the mower from the network and connect the ticks to the entrance wires along which the electricity enters the house, then ask the assistant to continue the mowing of the grass and observe the current, waiting for the traffic jams to train.
If a current jump is detected, then the intra.house wiring is faulty and requires replacement.
If the current increases not only at the entrance to the house, but also in the extension cord, then the problem is either in the extension cable or in the mower itself, so first replace the cable.
If this did not help, it is necessary to disassemble the mower and carefully check all the contacts, as well as the condition of the engine windings. However, for such work, it is necessary to understand the electrical engineering well and be able to repair it, because it is necessary not only to repair the damage or replace a defective part, but to eliminate the cause that led to such a defect.
If you do not know how to do this, then contact a specialized workshop.
The knife does not rotate when the engine is turned on
The reason for such a malfunction may be:
- chopped engine bearing;
- a chopped knife shaft bearing (only on mowers with a collector engine);
- weak tension of the knife drive belt (only on mowers with a collector engine);
- weak tightening of the bolt fixing the knife;
- Loss of a knife.
To establish the exact cause and fix, turn the electric lawn breeze upside down from the network and twist the knife.
If it rotates without resistance, then the lawn mower has one of the following damage:
- knife fixators are cut;
- The knife attaching bolt is not twisted;
- torn or stretched a knife drive belt;
- Distributed pulleys of engine or knife.
To check the tightening of the bolt, shake the knife, moving one or the other edge from the seat, if the screw is not tightened, the knife will hang out, if it sits tight, then the problem is in something else.
To check the locks, unscrew the bolt, then remove the knife and inspect the seat for it. if the locks are damaged, this will be immediately visible.
To check and adjust the tension of the knife belt, you need to remove the engine, so we recommend that this operation independently only if you are well acquainted with the device of your mower and know how to remove and put it in place of its electric motor. This process is not the same on various braids, so it is impossible to prepare universal instructions.
After dismantling the engine, do the following:
- Check the condition of all parts of the belt tensioner, bearings, rubber rings and springs should be intact;
- Remove the belt and check its length (for this house there should always be a spare belt);
- Check the condition of both pulleys, paying special attention to the inner surface where the belt passes and fixed the shaft.
Refresh or replace faulty parts, then collect the mower and check the work of the knife. As an example of such a repair, we suggest you see this
Strong vibration of the lawn mower
Strong vibration arises due to the fact that the knife:
An external inspection, even without removing a knife, will detect its deformation or poor fixation. If it is not bent and is normally fixed, then injected, as described above, then install on a mower and check its work.
How to replace (or change) a knife on a lawn mower
Non.tonsured areas of grass on the lawn. a certificate of wear of a knife. The blades are dull as a result of intensive operation, from mechanical damage: borders, stones, other solid items on the lawn. The problem is eliminated. replacing the cutting element.
Some braids are equipped with the lower lid, on which two shorter separate blades are fixed. Other models are equipped with one long blade similar to a ruler. Tilt the mower to inspect the blade. This will help buy new, suitable in shape, size, type and location.
The knives are suitable for re.use, they are hidden if the cutting edges are not damaged, there are no cracks, chips. With critical wear, replacement is required, since the cutting element may break during operation, inflict injury.
How to replace a knife on a lawn mower
Electric, gasoline technology blades require periodic inspection, dismantling for sharpening, replacement when damaged. This is done independently, it is enough to know the sequence of actions. For a simple repair of a mower, you need to do the following:
- Turn off the engine, unscrew the spark plug or disconnect the battery. This will eliminate the sudden launch of the drive, ensure a safe inspection and replacement of the knife;
- The examination of the knives is carried out with an empty fuel tank. To do this, drain the residues using a hose and a manual pump;
- Raise the body of the equipment to inspect the blade. It is important to make sure that the oil will not expand. Therefore, it is better to tilt the body towards the handle and support or ask someone to support the mower in this position;
- Pay attention to the position of the blade before dismantling for the correct installation of a new. Make appropriate marks. The assistant when replacing will be the instruction manual;
- Unscrew with the tasting key of the right size 2 fixing nuts, remove the cutting element, install the sharp, as the manufacturer indicated or according to the marks made, tighten the nuts in accordance with the recommendations of technical documentation. The main thing is not to pull the mounts, do not tear the thread.
Knife replacement is carried out in thick gloves to exclude the possibility of injury. It is also recommended to use a small block to prevent rotation of the blade when re.installed. It is laid between the blade and the hull of the mower to prevent a sudden turn of the cutting element.
If the replacement of the knives occurs in accordance with the recommendations, with the implementation of safety precautions, the process takes a matter of minutes.
The result. the braid works as usual, is not dangerous for the owner and others.

If you notice that in places there remains downstream grass where you have already mowed, this means that your lawn mower simply does not cut it properly. The knives wear out over time and must be periodically changed in order to maintain the efficiency of your lawn mower. You will support your lawn more healthy if you mow it less often by a lawn mower with sharp and clean blades. Replacing knives is quite easy and quick, if everything is done right. Start from paragraph 1 to get more information.
- Also, it is best to do this when there is no gasoline in the mower. Wait until you work out all the fuel, or drain it with a pump hose. Typically, such hoses are sold in any household or auto store. This will prevent fuel flowing to the mowing housing.
Turn off the spark plug. It is better to stay on the safe side if the ignition of oil or gasoline from the candle suddenly occurs due to a short circuit or electric discharge. If you raised the lawn mower correctly, such a problem should not arise, but it is still better to be on the safe side.  X Source of Information
Adapter of the Matrix Turbo Lawn mowing knife
To chagrin, Matrix-Direct graduated from supporting this product. In service centers in List.
Turn the lawn mower to access the cutting tool; Fix the knife using a wooden bar; Using the desired tool, usually a end or a united key, to unscrew the knife mounting nodes; Remove the knife itself.
After cleaning the knife from adhering grass, dirt can be started specifically to sharpening.
To sharpen a lawn mowing knife, a stable base will need a stable base for you. a table or a workbench, on the surface of which you can comfortably place and fix a knife for the final sharpening. A balanced option. if you have the opportunity to fix a knife in a vice.
When performing the work, keep in mind that the working part of the knife is hardened, you should try to ensure that the effect on the blade is the smallest and maintain the angle of sharpening of the lane of the lawn mower.
If the working parts of the knife are not damaged. burrs, zazubin, then you can limit yourself to the editing of the blade. Why can you use an abrasive bar or a file with a diamond spray. It is not necessary to remove a large amount of metal, and you can do with a “thin” tool.
If the knife blades have damage, before sharpening it is necessary to remove them with a rough file, on an emery circle or using an electric tool with an abrasive nozzle.
If you do work with a file or abrasive bar, then sharpening is made from the center of the knife to the edge. The movement of the tool is “from yourself”. After performing the work, it is necessary to check whether the balancing of the lawn mowed knife has changed.
The sharpened knife can be installed on the lawn mower and proceed to cutting the lawn.
Knife cleaning before sharpening
Before sharpening the knife, it is thoroughly cleaned. On steel stripes, plant juice and small particles of grass accumulate. At the same time, the juice hardens over time and turns into a hard crust. It is not worth washing the blades, it is best to choose a sharp metal scraper in the garage or apply a shade brush.
Do not polish the cutting element of the machine to shine, the main thing is to remove the adhering waste. After that, it is necessary to improve the knife, straightening it and deleting all the irregularities. Bugrs arise due to the entry of solid debris, stones on the blades. The correct option in this case is to work with a hammer. With the help of this tool and a flat work surface on which the knife is placed, you can correct all local curvatures.
Experts advise starting to align the blade from the edge, gradually moving to the middle part. As a result, the steel strip should become as flat as possible. Only in this case it will be able to perform its function, creating an air flow that transfers grass to the tank to collect plant residues.
A knife and a disk are regular cutting tools of trimmers with an upper engine location and a straight bar.
With a mowing of low spite of herbs, they are less effective than a fishing line for a trimmer, but ideal for cutting high thick vegetation, including young shrubs or trees, as well as thickets of various weeds.
Now you know how to put them on your trimmer for grass and what to do if you get an apparatus without details necessary for installing a knife or disk.
Chips on the choice
First of all, the knife should be durable and durable. The best material for knives is stainless steel of the desired thickness, and not, for example, black steel with stainless steel or galvanized iron. Sometimes manufacturers indicate a stainless steel brand, for example, AISI 304. A knife is not the detail on which it is worth saving.
For portable lawn mowers, the minimum solution is considered to be a blade with two knives. In other words. you should choose a knife with two cutting edges. He will cut the grass. but it will not grind it. To mulch the grass. buy a cutter with eight.e likely. The optimal angle of sharpening is approximately 30 degrees. You will quickly learn to recognize such knives.
The carving of the rotor pin on which the cutter is put on with its landing holes does not matter. It is usually left if the knife spins to the right. and vice versa. This helps to avoid unscrewing the nuts and flowering the knife at full speed.
If your choice still fell on plastic knives. look for a black and rather hard plastic, which longer retains the factory severity of the cutting line. Such does not scatter into crumbs from the slightest blow when carrying or rolling the lawn mower to the place of the beginning of the mowing of grass.
Most often, the malfunctions are as follows: the braid does not download the grass or does not turn on at all.
The mower does not mow grass
- A knife is blown or broken. Sile it with a file, an angular grinder, on a sharpener (you need a plane.cylindrical sharpener) or on a machine (or drill) using sandpias. Check the balancing of the cutter.
- The cutting itself is set incorrectly. Put a gap in a cylindrical mower between a rotating cylinder and a knife blades equal to a thickness of a piece of paper.
A rotor with a knife does not spin in a mower
- The knife itself was stuck. Pull the grass and earth from under it and scroll the cutter itself. He should rotate freely, without scratching and touching the protective casing.
- The drive belt is torn. Check the integrity of the belt. A worn, “sprinkled” belt must be replaced.
- Cliff on nutrition. Restore the ragged wire in the cord. Replace the cord if the insulation is disturbed.
- The switch does not work. Check the switch performance, try to turn off and turn on the mower. If the switch is unsuitable (melted, the contacts are burned). replace it.
- The supply voltage in the network is gone. Check the possible operation of the protection machine on the electrical panel.
- The fork is not included in the outlet. Turn on the fork in the outlet (if it turned out to be pulled out).
- The fuse in the device burned down. Check it using a tester (multimeter). If necessary, replace a faulty fuse.
- The thermal protection of the braid turned off the motor. Wait for the cooling of the motor after the mowing session of the grass.
Having checked all the details and nodes, finding a malfunction, run the mower. Most likely, your problem will be solved. In fuel lawn mowers, the guilt of everything is either a carburetor (or drive) or the fuel ended. Often the unstable operation of the motor requires the search and exclude breakdowns of a number of parts, before it is possible to find and replace the faulty.
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, simultaneously protecting 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.
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.
