Self -propelled mower does not go the reason. Is it possible to mow wet grass?

REPAIRS AND REPAIRS OF APPLICES

Lawn mowers are a convenient equipment that allows you to maintain in the country, in the garden, the park of herbal cover in a well.groomed state. Thanks to their use, lawns acquire an attractive appearance with minimal labor and time. Gasoline and electrical devices that have pushed to the background are popular with the popularity of mowers.

With proper operation, the equipment is capable of working for more than one year without breakdowns. But over time, the details wear out or an unforeseen accident may happen, as a result of which the unit will fail. If the equipment is not under warranty, then it is not necessary to contact the service center for help to specialists. Repair and maintenance of lawn mowers can be carried out at home. This is due to the fact that many malfunctions do not relate to serious breakdowns, they can be easily eliminated on their own.

The main malfunctions of electric and gasoline lawn mowers

Despite the variety of models and manufacturers of lawn mowers, gasoline and electric equipment has similar structural units. The difference lies in the types of installed engines and related systems for ensuring performance. Equipment malfunctions are conditionally divided into 2 groups:

Damage of the mechanical part of models with gasoline and electric motors is almost the same, but the refusal when operating the drive part of the lawn mower can be caused by problems with different details.

The design of the lawn mower

Now we will analyze the “anatomy” of this device. So, the gas mowing on a gasoline course is a four.wheeled device with a plastic or metal body in which the engine is enclosed. In simple and light models, he drives only cutting blades, so he has to roll a “four.wheeled friend” manually. However, it is not so difficult to move 12-15 kg from a place of 12-15 kg.

massive units are made by self.propelled. Their wheels rotate at the expense of the drive (chain or belt), and the user can only direct the lawn mower in the right direction. To make the work as comfortable as possible, manufacturers equip their models even with a speed switch (from 2.4 to 5 km/h).

As for the mowing process directly, almost all gasoline devices are rotary. The knives are installed in them parallel to the plane of the Earth, and during operation they create a strong air flow, which in turn draws out cut grass into the grass collector or throws it to the lawn, forward or to the side.

As we see, the device is quite simple. But, trying to raise the demand for their products, companies constantly add new options to them. It can be a special handle that reduces vibration, or a sensor that measures the height of the grass.

A separate mention is deserved by the mulching option that saves the summer resident from taking care of where to put mowed grass. To throw it away by waste, because this is a wonderful raw material for compost. But to rake the grass manually and attribute them to the composter tire. Why spend time and effort if the lawn mower can fertilize the soil on its own?

To transfer the unit to mulching mode, access to the grass collector is blocked. Small and crushed stems are poured onto the lawn, where they gradually decompose, turning into compost. But you should not get carried away in this way of fertilizer. Once a week enough. If you mulch the lawn more often, organic waste will accumulate on the lawn and damp, gradually turning it into a swamp. For the same reason, you can not work in mulching mode during protracted rains.

What to look for when choosing a gasoline lawn mower

The second parameter is the torque of the unit. The higher it is, the easier it will be to mow grass, especially thick and high. For the lawn on 1-6 acres, the torque should be about 6.1–9.83 h m. The maximum necessary for large land plots is 11.87 h m.

The body (deck) of the device is of great importance. It should be durable, since during the operation of the lawnmand of the blade, small pebbles and other hard garbage throw it on it. In the simplest, budget models of deck made of cheap thin plastic. Obviously, such a product will not last long. The metal case is much more durable, but it cannot be called impeccable. The paintwork, which is protected by the inner surface, abrasion over time, and under the influence of moisture (juice of grass), deck gradually rust.

The thermoplasty houses show themselves well. durable, reliable, not prone to chips. Multilayer plastic has established itself even better, which resembles Sandwich on the cut. As practice shows, it perfectly resists wear.

note! Starting from the end of July, many large produce and suppliers make significant discounts on the lawnmands, so the end of summer is considered the most profitable for buying garden equipment

Another important element of the lawn mower is a grass collector, the volume of which varies from 16 to 90 liters. It can be soft (durable waterproof bag), or hard (plastic box). The second option is preferable, since the product with smooth, solid walls is easy to empty and wash.

The method of launching matters. As mentioned above, in order to give the unit the action, you need to pull the starter cord. But there are models in which the engine is launched by pressing a button or turning the key. The electronic ignition system is powered by batteries. Lawn mowers with a hybrid system are also developed, where the launch can be carried out either using the/key button and using the cord. This can be very useful if one of the mechanisms fails.

The wider and larger the diameter of the wheel of the lawn mower, the easier it is to roll it around the site. Another plus of wide tires is that they do not leave traces on the lawn

Where to look for a reason or where to start checking

All chainsaws have the same design, and work according to one principle. The device of the chainsaw can be found in this material. It does not play much meaning which brand of the tool. Stihl, Husqvarna, Echo, Champion, Partner, Sturm and others. A malfunction manifested in the form when a chainsaw is stalling when pressed on gas can arise the same both on expensive and high.quality tools and on budget Chinese devices. If the problem has arisen, then it needs to be solved.

A chainsaw is a system of mechanisms consisting of details. Any detail in the mechanism can fail, which will lead to a partial or complete failure of the tool. If the tool engine starts, then this does not mean that the chainsaw is completely serviceable. Когда при повышении оборотов происходит прекращение работы двигателя, значит на то имеются соответствующие причины

With this malfunction, you need to pay attention initially to a number of the following tool mechanisms:

Gas tank. make sure of the presence of fuel. If fuel is in sufficient quantity, you should also check the serviceability of the fuel filter, the presence of a connection of the supply hose with the carburetor, and also make sure that the operability

These are the main details and mechanisms that should be checked first if there is a malfunction when the chainsaw stalls when the accelerator is pressed. There are other reasons why the chainsaw engine stall when the gas trigger presses. What else can contribute to this malfunction, as well as features of elimination of breakdowns, we will find out later.

The most common problems

The engine will not start

The reasons why the engine does not start is quite a lot:

• Empty fuel tank;
• Clogged air filter;
• The muffler is clogged;
• The ignition switch is installed in the wrong position or faulty;
• The throttle control lever is in the wrong position;
• Faulty candle;
• The carburetor is broken or clogged.

Initial review

To determine the true cause of this defect, you must first conduct a complete external test and make sure that the openings of the air filter or muffler are not clogged, that there is gasoline in the tank and that the throttle control lever and the ignition switch are in the correct position.

If everything is in order, then this is necessary to perform pre.launch work, including the cleaning of air or fuel filters, described in detail in the operation of the lawn mower, and repeat the attempt.

After making sure that the engine is still not starting, the mower is placed on the table and a more detailed search for the reasons begins.

First unscrew the spark plug and tightly twist the spark plug with your finger, then carefully, but quickly and reliably pull the manual starter or click on the electric start button. The movable piston should create sufficient air pressure to push the finger out

If this does not happen, the engine needs overhaul, which is difficult to carry out at home, so it is better to take the lawn mower to a specialized workshop

The movable piston should create sufficient air pressure to push the finger out. If this does not happen, the engine needs overhaul, which is difficult to carry out at home, so it is better to take the lawn mower to a specialized workshop.

After all, the reason is that the piston does not move after the rotation of the cable or shaft of the starter of the electric starter can be:

• A breakdown of the starter, due to which he does not convey the energy of rotation to the engine shaft;
• The shutdown key, which connects the flywheel and the starter with the engine, and also provides the correct ignition angle.

How are the engines of lawn mowers

Lawn mowers can work on the muscular strength of a person, electricity or gasoline.

Hand braids are the simplest, reliable and affordable. That’s just the performance of such devices is low. In addition, pushing the machine itself and set in motion knives, the mower should independently, but here we need remarkable endurance. Especially when to put in order a large and hilly area.

Network electric lawners are connected to a household electrical network using a cable. They can be very powerful devices, almost do not require care and are great for most lawns of small and medium sizes. One trouble: without a wire, a network braid will not work, so for work, most likely, you will need a good extension cord. And it can cost like half of the device itself.

The main drawback of network braids are deprived of battery models. They work on rechargeable batteries, due to which they are spared the life support system in the form of a compulsory electrical wire. Although, of course, the effectiveness and accessibility of this type of record is clearly not beaten, but the advantages clearly outweigh any disadvantages.

Finally, gasoline law mmores are arranged in much the same way as ordinary cars. Only the motorized motors are weaker and smaller. Devices of this class are characterized by the highest efficiency, power and complete autonomy. You can mow with a gasoline mower at least a whole field. it would be fuel. Unfortunately, devices with internal combustion engines are quite expensive, they require maintenance and exhaust gases air, frankly, do not ozone. For large lawns, gasoline braids are perfect, but it is better to look after a small courtyard with an electric model.

Humble lawn mowing from washing machine

Do.it.yourself electric lawnical mower from a washing machine to make it simple enough. The budget option will cope with the haircut of the lawn up to 5 acres. During operation, the unit cannot be overloaded. The engine should be disconnected periodically, giving it the opportunity to cool down.

Preparation of tools and materials

For the manufacture of a home.made apparatus, you will need:

• An electric motor from a washing machine, it is advisable to take asynchronous. such an engine is less noisy. Suitable motors from Soviet.style equipment with a capacity of 200 W, which due to heavy weight provide high stability and inertia.
• Semiautomatic washer switch.
• Durable wheels with a diameter of about 10 cm-they will be installed so that 5-6 cm remains to the ground.
• Strip of instrumental steel. thickness 5 cm, the length depends on the capture of the mowing.
• Metal sheet with dimensions 3050 cm, thickness. 5 cm.
• Profile pipe for the manufacture of the handle.
• Curlers of a steel corner for a frame.
• Three.wire copper wire and fork. The length of the cable depends on the size of the site. it is better to take the size with the margin.
• Consumables: bolts, stilettos, nuts.
• end and rye keys;
• electric drill;
• welding machine;
• corner grinder;
• pliers;
• soldering iron;
• a hammer;
• multimeter;
• Measuring tools.

Step.by.step briefing on the assembly of parts

Before starting to make a lawn mower, it is advisable to develop a visual drawing indicating the main dimensions of the device:

• full width of the capture of the mowing corresponding to the diameter of the rim for knives;
• knife lengths;
• the heights of the spine and the depth of the spit shield;
• Wheel diameter.

Details of the lawn mowers for your own assembly are given below.

• Manufacturing of the frame:
  make a frame from a metal corner;
• cut the platform for installation of the engine and prepare a hole for the engine shaft in the workpiece;
• on both sides of the frame, weld the racks for attaching the wheels;
• attach the platform to the body;
• Install the arc from the front side of the frame. this element will protect decorative plants from random mowing.
• Creating a knife:
  draw the borders of the cutter in the metal strip;
• sharpen the knife cutters;
• Make a hole clearly in the center of the part for attaching to the shaft of the electric motor.
• Preparation of the handle:
  choose a comfortable handle height. about 90 cm;
• from a metal pipe make a P-shaped handle;
• Wrap the handle with insulating material (island or rubberized casing).
• Compound details:

• On the sides of the platform, install the wheels;
• weld the handle to the frame;
• Install the engine on the platform. place the shaft in the hole on the basis of a mower;
• Attach the knife to the motor shaft. the cutter must be specified and balanced (when scrolling, the knife is not overwhelmed);
• It is advisable to cover the engine with a protective casing with small holes to prevent overheating;
• Connect the cable to the motor, fixing the cut with the fork and the switch to the handle;
• Check the joints, cable integrity and perform test launch.

Replacing drive belts in a snow removal machine

The drive belts of the snowman are designed to transmit rotational movement from the drive shaft to the driven.

2 types of belts are installed in snowplifier machines. The first belt connects the shaft of the screw of the unit with the leading shaft, and the second transfers rotational movement to the wheels.

Therefore, if the snowman does not go forward, or its screw does not rotate, then you need to believe the belts and, if necessary, replace them. To install the belt on the snowpock machine, perform the following actions.

• Disconnect the groove from the snow removal.
• Remove the protective casing that closes the pulleys with belts.
• Disconnect the screw mechanism from the engine of the apparatus, unscrewing several bolts.
• Next, you need to put on a new belt on the pulley of the snowman, that is, on the pulley of the screw mechanism. The size of the belt should be the same as that of the torn.
• Put up the screw mechanism (you may need another person’s help) to the engine and put the belt on the pulley of the drive shaft so that on one side it falls under the clamping video with the spring attached to it. The video serves to pull the belt.
• When you fasten the screw mechanism to the engine, the replacement of the screw belt will be completely over.

In cases where the unit refuses to go, there may be 2 reasons: wear of the friction ring and rupture of the wheel drive belt. If everything is in order with the cloth, then to eliminate the breakdown it remains to change the drive belt.

Replacing the drive wheel belt is performed in the same way as the screw belt. Only after disconnecting the screw mechanism, it is necessary to remove the lid hiding the wheel drive pulley (indicated by the arrow).

The snow.offer screw does not spin or spin slowly

Problems with the rotation of the screw can be caused by several reasons: cutting protective bolts, insufficient tension or breakthrough collapse of the screw drive, breakdown of the gearbox of the screw mechanism.

Replacing the cuts

The fact that the snowplower screw does not spin, not only the screw belt that broke, but also the cuts of the bolts can affect. The latter are made and soft metal and serve to fasten the screw.

If a rotating screw encounters any obstacle, for example, with a curb or stone, then the bolts are cut off, the screw stops, and you notice that it does not throw snow when the engine is running. Thus, cutting bolts perform a protective function and prevent a breakdown of the gearbox, as well as the screw itself.

Replacing the cuts, if the screw does not rotate, is quite simple. It is necessary to combine the hole on the screw with the hole on the shaft and insert a bolt into it, then fix it with a nut or a spring clamp, as shown in the next photo.

Replacement of the cable of the screw drive

Sometimes the weakening of the screw drive cable becomes the reason that the snowmaker poorly throws out snow. This is due to the fact that the clamping video with a cable connected to it with insufficient force presses the drive belt. Sometimes this cable is torn, which leads to a stop of a snowpock screw. In this case, you will need to replace the cable of the screw drive. First, the cable is removed from the unit handle, and then disconnected from the clamping roller.

Repair of the Schnek gearbox

Repair of the screw, or rather its gearbox, responsible for the transfer of rotational movement to the shaft of the screw, is required when the shaft of the latter does not rotate, or its movement occurs with jerks. The gearbox usually fails due to the natural wear of the gears.

Sometimes the teeth of the gears can break if the user installs on the shaft of the screw instead of trimmed bolts ordinary (metal). In this case, when a mobile screw falls on a solid obstacle, the bolts are not cut off, and the entire load falls on the gear of the gearbox, from which they fail.

In the following photos you can see how the new and worn gear gears look like.

To remove the gearbox, you will need to disconnect the entire snow removal mechanism from the engine. How to remove a screw described above. Next, you should disassemble the screw to get to the gearbox installed on the shaft.

The gearbox body consists of two halves, which are fastened with bolts. After removing the bolts, the case will be separated, and you will see a regular gear and worm installed on the shaft.

Most often, teeth on an ordinary gear break, so it should be removed from the shaft and replaced not a new one.

Advice! Before twisting with each other, two halves of the case abundantly apply graphite lubricant to all gear of the gearbox.

After lubrication, twist the gearbox and collect the entire snow removal mechanism in the reverse sequence.

The mowing motor pulsates

Try to clean or replace the spark plugs. However, if this does not work, but the engine continues to pulsate and twitch, it will be necessary to contact a specialist, because again the problem could arise in the carburetor or its mixture.

Before you go to the workshop, try to replace air filters, spark plugs and make sure that cruise control is in the correct position. It should be raised as much as possible.

If you have already taken care of oil, try to clean the ventilation hole or replace the spark plugs.

There is a lot of smoke from the lawn mower

It is possible that the oil got into the mower due to improper positioning. In this case, the device must be left on and wait until all the oil is burned out. the smoke during this process can be especially thick.

Then make sure that the oil level is still sufficient. If these actions have not helped, you will definitely need to seek professional repairs.

When opening an air damper

It happens that the unit stalls when opening an air damper, working normally at idle. This is due to the air leaks of the system caused by the presence of fuel hose cracks or problems with the oil seals. The carburetor dosing system can also work malfunctioning, while the lawn mower will stop after the opening of the damper.

All possible reasons that the lawn mower stalls, and the methods of eliminating them are contained in the next video

There are many reasons for stopping Motokos, but the most commonly occur in work related to its carburetor. They can arise in any case. The most problematic option is when there is a serious breakdown, and you will need to purchase new parts or change the lawn mower.

So that the trimmer for the grass works normally for a long time, you should strictly comply with the requirements of the operating instructions. It is necessary to refuel the unit suitable for it in the composition with a fuel mixture, the device should work with a moderate load.

Tools for diagnosing the electric motor

To identify problems in lawn mowers with a different type of drive and elimination of them, such devices and tools will be needed:

• indicator screwdriver;
• multimeter or tester with voltage indication;
• screwdrivers;
• keys of an abyss or hexagonal (depending on the fasteners used in the assembly of the equipment);
• pliers;
• Kusachki;
• knife;
• a hammer.

Of the materials, an insulating tape and the details identified during the verification may be needed.

The causes of breakdowns of lawn mowers are associated with the following factors:

• overheating or overload of the motor;
• bad contacts or ruptures in an electrical circuit (in electrical models);
• violation of the supply of fuel or oil (in gasoline units).

Therefore, you need to periodically, focusing on the recommendations set forth in the operational instruction, make stops during operation and constantly clean the equipment from herbal residues.

For internal combustion engines, the appropriate oil and the gasoline brand indicated in the passport should be used.

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.

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.
