Can I mow with a trimmer when it rains?

Can I mow wet grass with an electric lawnmower

and more often, dacha plots are no longer just places to grow fruit and vegetables, but also places to relax. They allocate areas on which put gazebo with barbecue and break up flower gardens and lawns. To have such a lawn not much effort is needed: to water it in time and to mow it.

Once the lawn grass seeds have been sown, you should immediately wonder what tools you need to mow the lawn. You can’t make an even cut with a simple scythe. A large number of different tools are available for this purpose:

Grass trimmer

Represents a rod with handles, a special spool and a motor, which can be electric or gasoline. The spool has a bobbin, on which a special line for the trimmer is wound or a knife is put on.

Take note! An electric grass trimmer is simply plugged in, and it’s ready to go. It’s light, handy, but it requires a long wire and the presence of a socket, which is not always convenient. Mowing a large area will be difficult.

  • Low-power. Comfortable, lightweight, but can’t handle tough, wet grass and weeds.
  • Powerful. They are available with a bottom-mounted motor and with a top-mounted one. It is possible to install a special blade, which allows you to mow coarser grass. Bottom-mounted models cannot mow wet grass.
  • Cordless. lightweight, mobile. The disadvantages include the fact that the battery charge lasts for an hour.

grass trimmer with a gasoline engine is heavier than an electric mower, but it differs from it in mobility. It has a forged shaft, shoulder straps and a powerful power drive. The gearbox design allows you to use not only a line for the trimmer, but also a knife and toothed disc, which greatly improves the quality of processing the area. The gasoline mower can mow very large areas.

Trimmers can mow in hard-to-reach places (under benches, near pillars), as well as mow paths regardless of their location.


It’s clear why this machine is called a lawn mower. Looks like a cart on wheels with special blades and a device for collecting the cuttings. Lawn mowers come in different models:

As with trimmers, gasoline lawn mowers are mobile, can work far from home. But they have a big weight, more complicated use and also they make a lot of noise.

Lawn mowers with electric motors are lightweight, do not make much noise, are well cleaned, are absolutely harmless to the environment. The disadvantages include the need for nearby power supply.

Cordless are all good: a little noise, the lawn is flat, easy to work, but the battery lasts for a certain time.

Spindle mowers are those without a motor. The device is designed as if the lawn is mowed with scissors. It is very beautiful and neat, but the process is very time consuming.

Lawn mowers

This tool is used where it is impossible to work with a lawnmower or trimmer.

Safety precautions during work

Technique trimmer work with a string and disk has some differences. For example, a line for a trimmer cuts the grass at the very end, but if you go too fast, it cuts the whole length. As a result, the stems are not cut, but the grass is wound up on the cord, causing overloading of the engine. So you need to choose the optimal speed wiring. over, mowing tall and tough grass consumes trimmer lines faster than mowing the lawn.

There are a few simple guidelines to make mowing more efficient and effective.

  • The bottom-mounted trimmer is convenient for mowing garden paths, flowerbeds, and edges of lawns. The plane of rotation of the reel of such a device can be placed perpendicular to the ground.
  • Dense thickets, large weeds, bushes should be mowed with discs or special attachments.
  • When working on large areas, the machine must be tilted to the left in the direction of the swing.
  • To cut the grass around flower beds, bushes and other objects, turn the grass trimmer head with the blade of shade towards them. This way you can mow the objects themselves without damaging them.

Remember, the bobbin or disc must not touch the ground or any obstacles other than grass and twigs that need to be mowed.

When working with brushcutters, observe the following safety precautions.

  • Do not use your trimmer in rain or high humidity.
  • People and animals should be at least 15 m away from the cutting head: grass clippings, small debris and stones fly out from under the cutting head at high speed and can injure.
  • The grass trimmer operator should wear heavy clothing that fully covers arms and legs.
  • One should wear safety glasses, gloves, headwear, closed shoes, special earphones or earplugs.
  • The lead of the power grass trimmer should be behind the mower.

So, the use of handheld devices for mowing grass allows you to maintain order on a small plot. Large lawns are easier to mow with a lawn trimmer. In addition, the grass trimmer is relevant when making hay and putting in order on the territory: small grass clippings can be mulched strawberries and other useful plants. See how you can mow with this tool in the video.

Mowing with a cord trimmer is safer, but not always as optimal as with a disc. As they say, it is worth choosing a cutting mechanism for the peculiarities of your site or use complete systems, where you can operate both disc and line for the trimmer, if necessary, installing the first, then the second.

As we have already written, lawn mower with a fishing line can be automatic, semi-automatic and manual. In the first case, the cutting element is “thrown” itself after each new start of the machine. This is very convenient, but not economical enough, for example, if your area is irregularly shaped, and contains corners, jagged edges, and at a long transition to each of these areas, the mechanism must be novaova turn off and on.

It is important for the operator to understand that the length of the line ends that he sees in front of him when stretched out is exactly the diameter that will mow the device. You can read the rules of threading the line in the spool in one of our articles, but the main thing to remember: the length of the line ends should be optimal for a competent mowing.

How to mow with a petrol-powered lawnmower correctly? This should be done so that it will last you as long as possible:

  • keep the reel 10 cm off the ground;
  • When working with tall grass. mow it at the top, and then already at the stem, to protect yourself from its winding on the device;
  • Drive the machine in the same direction as the coil rotates;
  • Lawn grass, especially near the walls and garden décor, it is better to mow with the ends of the line, so as not to overload the engine;
  • Take a break every 15 minutes.

Any answers to your questions about mowers you’ll find in this section of the site, but we’re also happy to offer spare parts for lawn mowers among our other range of gasoline tools.

Ideally, tall grass can be mowed with a powerful trimmer with a thick fishing line. But, agree, the land where the weeds grow. not always smooth, often landowners on the plots there are bushes and all kinds of debris, stones. In order not to ruin expensive equipment. it is better to mow in two steps.

In the situation if you have to make hay, and you are more or less aware of the condition of the ground, then it is easier to predict your work. Any technique designed for mowing grass. can also cope with tall thickets. The main thing is not to hurry and to approach the process intelligently, as we demonstrate in the practical video.

  • Do not overload the machine;
  • if the grass gets tangled, turn off the machine immediately
  • Do not mow wet grass, even with a gasoline trimmer.

Grass Trimmer Usage Rules

In addition to the mandatory adjustment and running-in before you start working, you need to observe a number of rules to make mowing comfortable, the result. the best, and the service life of the machine. for a long time.

Using the belt

Before you start the grass trimmer, you need to attach the belt to the assembled and ready to work device. fasten it to the boom with a metal loop. this type of mounting is designed to withstand a high degree of stress and strain for a long period of time. Some models allow the strap to be placed on one shoulder, others on both shoulders (shoulder straps of the backpack type). When you mow large areas, your arms and back get tired from the weight of the machine, but if you put the belt on properly, you can reduce the load and prevent muscle and joint pain.

Lawn mowing

A cord is needed for this task, as lawn grass is softer than normal. First make sure there is no large litter, branches, wires, stumps or uneven areas to be cut. The lawn must be cut evenly, i.e. the height of the grass must be the same in all parts of the lawn. To mow properly with a line trimmer, the device should be kept level with the ground at all times, driving it from right to left, smoothly and without haste. You can divide the area into squares and trim these one by one. Move from one to the other in a clockwise direction.

Tip! If you need a minimum height lawn, the angle of the device to the ground should be at least 30 degrees, so that the line for the trimmer almost touches the surface. Mistakes can be cleaned up manually with a pair of lawn shears.


The hay should not be too fine, so you have to mow at the root. It is better to mow with a disc, because meadow grass is tougher than lawn grass, and a trimmer line will not cope with it. You need to lower the grass trimmer as low as possible, try to mow strips of equal length. It is best to mow shrubs and large weeds with strong stems in a circle to avoid damaging the disc. Grass trimmer, as in the case of the lawn, should move from right to left.

Mowing tall grass

In this case you should trim from side to side twice to remove the height of the grass, and then mow it to the root. You may need three or more movements. it depends on the length of the stems. It is better to cut hard grass at the base with a disc.

Important! It is best not to mow high grass directly to the roots. the stems may wind around the trimmer line and overload the engine.

Mowing wet grass

It is dangerous to mow grass with an electric tool during and after rain! Moisture can cause a short circuit in the motor, the grass trimmer can burn out, and a person can get an electric shock. Dew is also a problem, especially with low-mounted models and models with a power strip. Mowing wet grass is safe with a brushcutter, though low-rated petrol models need to be protected from rain.

Important! Whether or not the grass trimmer model is rated for wet grass is specified in the instruction manual. After mowing, any type of wet grass trimmer should be thoroughly dried.

Speed selection

Spindle speed adjustment is only possible on petrol models. This option is used for different types of work:

  • low revolutions are suitable for mowing lawns;
  • Medium is for tall grass and thin shrubs;
  • High. for cutting thick branches and bushes.

How long the grass trimmer can mow

An apparatus with an electric motor can operate for up to 20 minutes per switch-on. Then it needs to be turned off for the same amount of time for the engine to cool down. Battery charge should be checked periodically.

Lawn mowers can run for up to 40 minutes or even an hour without interruption of engine cooling. Then they need to be shut down for 10-20 minutes. How long a lawn mower will run also depends on the size of its fuel tank.

The role of the equipment

From the beginning it should be pointed out that there are two basic types of trimmers, which differently “relate” to wet vegetation. Some machines are equipped with a gasoline motor, others are powered by connecting to the electricity grid or installing a battery. In turn, electric mowers are divided into two subgroups: with the location of the motor in the lower or upper part of the device. Safe enough for the user to remove wet grass can only gasoline grass trimmers or hand-held grass mowers.

Using an electric lawnmower in such a case is absolutely undesirable. Sometimes you can find statements that this requirement applies only to devices with the lower motor location. Such an electric motor comes into direct contact with water. Because of this contact, there is a risk of a short circuit.

But using a top-mounted electric lawnmower after the rain is also not a good idea.

If water does get inside the propulsion system, there is not only the risk of a short circuit, but also the risk of an electric shock. It’s worth noting that these restrictions apply not only to grass trimmers, but also to complete lawn mowers. The manufacturers and marketers’ claims about safety should not be taken into account. To minimise the risk to yourself and your machine, it is worth using a chain saw. But there are still a few subtleties that must be taken into account.

Even if the mower does not fail and its owner is not electrocuted (let’s assume such a favorable situation for a minute), it is still impossible to mow damp grass with an electric trimmer. This is a known abnormal operating mode that causes the equipment to wear out too quickly. Wet grass and leaves put much more resistance on the cutting elements than they should. This is why even very well insulated motors run with overload.

Wet grass adheres to the blades and spindle and causes an increased stress for the blades and spindle. There is no way to avoid it and no skill of the mowers, no methods and schemes of lawn clearing help. It is not only the motor that suffers, but also the shaft that sometimes rotates.

Problems can also occur with petrol mowers when mowing wet grass. Yes, they are more powerful than their electric counterparts, but the load still exceeds the normal values. Pistons and other moving parts are the ones that get hit first. If there is no choice but to use a gasoline mower, you need to take care of it. When mowing wet grass, periodically switch the machine to an idle mode with no load. 30 seconds is quite enough to dissipate the excess heat, and also to save the grass trimmer’s resource.

But it’s not as easy as it looks. Another reason why it’s better to mow dry grass is that cutting a wet lawn is bad for the vegetation itself. If you look carefully, it is easy to see that even cuts are not as straight as they should be. Cuts in the stalks dry out and the grass turns yellow. The danger can be reduced a little by using a thinner line for the trimmer. Judging by reviews, square or star-shaped lines allow even wet lawns to be mowed evenly. But there’s another problem: The cuttings don’t spread out evenly, but rather in piles that must be removed as quickly as possible to avoid gaps in the grass.

When they talk about mowing wet grass, you need to distinguish between the following possible situations:

In the first case it is quite possible to risk and try to restore order with a gasoline mower. In the second case mowing is not advisable. The third one will have to deal with the moisture first and only then get the lawn or lawn in order. If you often have to mow wet grass after rain or “on the dew” in a small area, it is better to use not a trimmer for grass, and not a lawnmower, and a simple handheld mower. It is necessary to look not only at the grass that is being removed, but also at the one where the power cord is put.

Wetting it can be a very serious risk factor. For mowing grass after rain, you have to wait a little longer. A few minutes, even in a very big hurry, will not noticeably reduce the time you can dedicate to mowing.

And the result can clearly be better. Mowing dewy grass, even with an electric lawnmower or electric trimmer, is usually allowed.

As for mowing wet grass, there are still the following objections to it:

  • walking with a trimmer or lawnmower in such conditions is more difficult, you can easily fall and get injured;
  • Have to spend more time on the job;
  • The machine itself will need to be cleaned more thoroughly after mowing;
  • Wet chlorophyll will leave more stains on clothes, skin, shoes.

Main equipment failures

Any technique breaks down at the most inopportune times, and lawn care equipment is no exception. The following are the most common breakdowns with gasoline-powered mowers:

  • Engine defective. It is necessary to check the fuel in the tank, the functionality of the spark plugs, the cleanliness of the filters.
  • Carburetor clogging. Check the gasket between the carburetor and the engine, blow out the fuel hose.
  • Muffler malfunction. Clean the anti-sparking grid.
  • Gearbox damaged. Check the gears and bearings.
  • Starter malfunction. Check cord tension.
  • Problems with the air filter. If the lawn mower starts without a filter, it must be replaced with a new one.

Important! If carefully monitored, preventive maintenance and component replacement are performed, the appliance will last a very long time without needing any repairs.

The electric grass trimmer is simpler than its gasoline relative, therefore, it has fewer problems, but still there are:

  • The electrical cable is faulty;
  • the socket is defective;
  • there was damage to the plug;
  • there is a problem with the control knob;
  • the motor stator has burned out;
  • there was a breakage of the contact connection.

To detect the above problems, you can use an indicator screwdriver and multimeter, and to fix the breakage in most cases you need a soldering iron.

If you follow safety rules, including under no circumstances mow wet grass with devices that run on electricity, and refrain from mowing wet lawns with gasoline mower, so as not to harm plants, the tools will last long enough.

The arrangement of green lawns at dachas and country estates is becoming a popular activity. At first glance it seems that everything in this case is simple: the allocation of space for green lawns, seeded the site with grass and waiting for the transformation of the field into a green lawn. And only later comes the understanding of the need for proper maintenance, and he, above all, is the skillful operation of lawn mowers. It turns out that the lawn should not only be mowed for beauty.

Why you should not mow with a trimmer Wet grass

There are also indirect prerequisites to why you can not mowing Grass wet from dew or rain on the lawn. These include:

The most common way to break a brushcutter is to mow damp vegetation? The answer is simple. It is withdrawn because of the short circuit when water enters the power compartment. In addition, even if our customer remains perfectly sealed, there is a great possibility that the engine will not be able to withstand the heavy load created on the flexible shaft of the grass trimmer. And the shaft itself could spin. Such loads are in most cases caused by sticking wet grass on the spindle where the blades are mounted.

We trimmers with gasoline engine, grass mowing in wet weather, because of the huge loads, increases the degree of wear of the main components and assemblies. Here we note the early failure of the piston pair, well, in addition the other moving parts. In most cases the piston pair burns out because of overheating of the motor. In our case the motor will overheat from the load created by the wet grass when mowing.

If you mow wet grass gasoline trimmer to overheat the motor let him work for 30 seconds at idle speed without load. This method allows you to dissipate excessive heat and protect the piston pair.

Can you mow wet grass with a trimmer?

Using such equipment as grass trimmers for mowing wet grass is not recommended. This is due to the fact that in the care of a wet lawn can happen:

When using a brushcutter, wet grass may get caught in the engine compartment while cutting. This in turn can be the main cause of a short circuit. Also, it should be noted that when mowing wet lawns, a strong, excessive load is created on the shaft, which can not withstand the engine of the device. Also, under high loads, the shaft can turn, which is the main reason for the failure of the used unit. Such high loads are caused by the fact that during mowing, wet vegetation starts to stick to the blades and spindles of the device, significantly hampering their operation.

Apparatuses that are equipped with gasoline engines, when using them to mow wet lawns, often prematurely wear out the main nodes on the units due to excessive loads. As a rule, as a result of increased load, such devices not infrequently fail the moving parts, as well as the piston pair. When mowing wet grass, the high load causes the engine of these brushcutter models to overheat, which can lead to damage to the piston unit.

On a side note! When using gasoline trimmers for mowing wet grass, to prevent severe overheating of the engine, it is necessary to let it work periodically (about 25 seconds) in so-called idle mode during operation. This will remove excessive heat generated, prevent the engine from overheating, and consequently keep the piston pair in working order.

How to use a lawn trimmer

Garden trimmers for grass are effective. Beginners think that working with a lawnmower is quite simple, because you just need to plug it in or fill it up with fuel, but this is not true.

The efficiency of garden tools and their service life depend directly on the operating conditions. Therefore, before using a grass trimmer, it is necessary to perform preparatory work.

READ Can I mow wet grass with a chainsaw

Carefully inspect the lawn that you can mow. Be sure to remove glass and large rocks. They can injure people if they fly out from under the working mower. The wire is removed from the lawn because it can get wrapped around the rotating element, breaking the mower.

Then move on to installing the cutting system. There are small power grass trimmers on the market that use only a trimmer line. Designed for mowing lush and soft grass. But there are models with more than 1 kilowatt that are equipped with metal blades. They cut sown thistles and other hard weeds and trim back young shrubs.

To replace the cord on the blades, unscrew the attachment nut, install the cutting element. The nut should then be returned to its place, tightened with a wrench.

The operator must take care of his or her safety. Wear tight protective clothing when mowing. Use special glasses to protect your eyes from dust, grass and flying debris. Wrap your hands with gloves.

The electric grass trimmer is plugged in, and the battery models are charged several hours before use. Fuel is poured into the gas mower.

The lawnmower is held so that the spool or blade is parallel to the ground. When the tool is in the correct position, start the engine. After cutting the grass the lawnmower switches off.

First start

The operator assembles the lawnmower before the first start, the procedure is described in the instructions provided with the product.

If the grass trimmer is petrol, it must be checked before use. The fuel tank is filled to the neck.

The engine should run on fuel, so run it for a few minutes without any load the first time you start it. Then start mowing the grass.

How to fill a gas grass trimmer

Gasoline grass mowers come with two- and four-stroke engines. The first option is much more common. What are the differences between the two:

  • Grass trimmers with a two-stroke engine respond faster to the push of the power lever (for this reason, brush machines are mostly equipped with this type of engine);
  • A tool with a two-stroke engine will be much simpler and also easier to maintain;
  • Fuel consumption of a two-stroke engine is about 30% higher than that of a four-stroke engine with similar power;
  • The 4-stroke engine is more environmentally friendly, because the fuel in it burns completely and is not emitted into the atmosphere, and its noise level is much lower;
  • And the most important distinguishing feature is refueling: the two-stroke engine has one common tank that is filled with gasoline mixed with oil; the 4-stroke engine has a separate gas tank and engine oil tank.

For charging it is necessary to use fresh gasoline AI-92 or AI-95 and high-quality engine oil for garden equipment (manufacturers produce different types of oil for 2 and 4-stroke engines). You can use mineral, semi-synthetic or synthetic oil.

The ratio of gasoline to oil for two-stroke trimmers can be found in the instruction manual for the specific model. Usually it is 50: 1, in some cases a ratio of 25: 1 or 40: 1 is recommended. Fuel mixture must be prepared in a separate container with exact proportions. Never pour liquids directly into the tank without first mixing them. Detailed instructions for mixing gasoil, with videos and descriptions, can be found on our website here.

Operates at

Lawn mowers must be started before beginning work. Operator turns on the engine; it should stand for a while. Make sure the engine does not overheat.

As the mower runs, the load increases gradually. If you start at high speed, the engine will run poorly, which will affect the further operation of the lawnmower.

At first start-up, there is no need to fully develop a temporary resource. After the engine idles, you can start mowing the lawn. The lawnmower should not run for more than 15 minutes, after which the engine is turned off, it should cool down.

If you want to start an electric grass trimmer, first assemble the belt. Then perform a test run at least 3 to 5 times. If the motor runs fine, move on to mowing. At first, they work for no more than 5 minutes, then the work duration gradually increases.

How to wear the strap

If the tool is mounted on your shoulder, it hangs on your shoulder before use. Grass trimmer is attached to both shoulders if he has a backpack.

The bike handle model is held with both hands, the D-handle wraps around your palm. The belt should be worn so that it is comfortable, then the back will not get tired.

How to mow the lawn to keep it straight

To cut the grass evenly, lower the mower as low as possible while working. The plot should be divided into squares. You need to work in a clockwise direction. That way the hay will always lie to the left without getting in the way of your feet.

Slashing under the hay

It’s better to mow with a metal disc, not a fishing line. The grass is cut under the root, keeping its length as much as possible.

Mow tall grass

If you need to mow tall grass, it’s done in several passes. Mow the lawn 2-3 times. The rotating part is lowered from top to bottom, in which case the grass does not wind up on the reel.

The operator must remember that traumatized grass around the bobbin causes the motor to overheat. If this happens, the brushcutter is turned off and the bobbin is cleaned.

It is most effective to cut the grass with the tips of the line, not the whole length. In the second case, the tool performs worse and the motor may be overloaded. If you need to cut grass over a large area to increase efficiency, the grass trimmer should be tilted to mow.
