What trimmers can mow wet grass

To understand which trimmers are good for wet grass, and which are not, get familiar with their construction. To date, two main types of brushcutters are available to the consumer:

Electric trimmers, depending on the location of the engine can be:

For safety reasons you should only mow grass wet from rain or dew with a petrol-powered trimmer or a “litovka”. But using an electric brushcutter is highly undesirable. Especially for devices with a bottom-mounted motor, as they are in the area of water ingress. This can cause a short circuit.

Grass cutting during rain and with top-mounted electric lawn trimmers is not recommended. If water gets on the power unit, it may not only short out but also electrocute the mower.

Wet grass should not be mowed with electric lawnmowers either. The reason is the same as with bottom mounted power unit trimmers. there is a good chance of a short circuit. There is also a risk that the power lead supplied to the machine may be accidentally cut through if you are not careful.

If there is still a need to cut the grass in wet weather or in the dew, it is better to use carbureted brushcutters and lawnmowers. It will be much safer for life and health.

Variety of tools

Three versions of garden trimmers are available for sale. electric, cordless and gasoline. Networked models, plugged into the socket, are less common, as they have minimal opportunities for autonomous operation due to the connection to the power grid. In addition, in terms of economy, it is not the best trimmer for cutting the grass. Electric unit can justify itself only in the work in the areas adjacent to the house, if there is an opportunity to supply extension cords for connecting cables.

Potential for churning flying rocks puts windows at risk in homes and on cars. Shields around the trimmer head are in place to reduce flying debris and protect the operator. no one removes the shields after a modified grass trimmer is no longer under warranty or can be used safely.

When re-filling, make sure the engine is stopped and the grass trimmer is set on a flat, level surface. preferably not grass. Grass trimmer should never stay on the grass for a long time. Refill with the proper system to avoid leaks or overfilling.

The direct competitor of electric models has always been considered a gasoline modifications. They provide high power, virtually limitless movement, and handle even shrub cutting. But, the gasoline grass trimmer for mowing the grass is also characterized by its heavy weight, noisy operation, strong vibrations, exhaust emissions and high cost. Cordless versions are not tied to a power source either, but they lose out to gasoline trimmers in terms of power.

Be sure to use the appropriate string weight as indicated in the owner’s manual. Grass trimmer string that is too thick for the motor can cause damage. Some grass trimmers can accept a trimming blade, but never use a blade on a trimmer that is not designed to use trimming blades. Accessories that are not designed for a particular grass trimmer can create excessive vibration, engine wear or binding. This can lead to motor strain, possible component failure and potential damage to the operator.

How to mow grass with a trimmer with a metal blade

As you move the edge of the mowed area, move the fuel and bag as well.

If the grass has fallen: you need to bring the wheel forward and mow to the left with a tilt at the handles to the left (sector ~11 hours) and to the right with a tilt at the handles to the right (sector ~1 hour), and do not hurry!, To mow the grass cleanly and not to “dig” the ground.

As you mow the grass (and turn around), don’t forget to look around!:

  • To notice the gestures of others, turn off the engine and take off the headphones,
  • To keep children, animals, spectators, and helpers within 15 meters, t.к. when a metal blade collides with a stationary object in the grass, the grass trimmer or lawnmower (brushcutter) can be thrown strongly to the side or turned back, and the grass trimmer blade rotates at up to 10,500 rpm. and he is able to cut off an arm or a leg. Also, when mowing grass with a trimmer various objects (chips, glass, debris) can fly out from under the blade and ricochet.

How to mow grass correctly with a trimmer (more about mowing techniques)

Engine speed when mowing with a trimmer is set depending on the load on the engine. the thicker the grass and, of course, heavier the engine, the bolder you must open the “hole” (throttle valve in the carburetor diffuser).

Try to keep the engine speed constant (slightly above average) during grass mowing with the trimmer. or less gas. only according to the total load on the engine. Don’t completely drop the throttle (and immediately accelerate again) every time you swing the grass mower. So clutch “burn” not long, and the edge on the drive shaft can “overtake”, and the total wear and tear grass trimmer (brushcuts) dramatically increases.

Before mowing grass, find out the following site parameters

(to know what blades to take, how much fuel and time to use)

  • The density of the grass;
  • the hardness of the grass;
  • the grass clods;
  • the intertwined nature of the grass;
  • (the height and thickness of the grass are not important)
  • boundaries of a plot
  • which bumps (how to go in);
  • The presence of hidden obstacles (remember)
  • What not to cut (bushes, flowers, seedlings).

Mowing grass in the summer is a disaster, not just a chore of how to use a trimmer. If your yard or area is heavily overgrown with grass, you may be frightened by it, but this part of the article will help you understand how to mow grass with a trimmer easier and less annoying.

How to fix a disk or fishing line on a trimmer

The cutter bar is attached to the actuator. The attachment point is called the gearbox. The task of installing the disk or reel is not difficult. The principle of attaching the cutting blades to the trimmer is as follows

  • Initially fix the shaped washer by using the hexagon socket wrench
  • Place the disc on the shaft
  • Then install the upper washer, then screw it on with the securing nut
  • Turn the nut by means of a special socket wrench, which is usually supplied with each tool
  • The nut should be turned anticlockwise
  • Use an Allen key to wedge the shaft in place while turning

The removal and replacement of the disk on the trimmer is performed in the opposite sequence. For more details on how to install a spool of fishing line on the lawnmower, see this material.

Introduction to the tool

The question of how to mow with a brush and trimmer is mostly asked by beginners who have recently purchased these tools. We recommend that you familiarize yourself with the design and construction of the hedge trimmer before beginning work. The main structural elements of the tools in question are:

  • Two-stroke gasoline engine. There are tools with 4-stroke engines, the disadvantage of which is their high weight
  • Fuel tank. a tank for storing diluted gasoline and oil
  • Transmission. the transmission mechanism by which the torque is transmitted from the engine shaft to the drive.
  • Starter. a device for starting a gasoline engine
  • The rod is a rigid base that connects the engine to the working body

In addition to gas trimmers, manufacturers also produce analogues for electric and battery-powered. The main disadvantage of gasoline units in comparison with electric and battery-powered ones is their heavy weight. Weight of gasoline trimmers reaches 8-10 kg (4-stroke), which depends primarily on the power. To simplify the work of the tool, manufacturers complement their units with special belts, which are also called unloading belts.

You need to know the design of the tool to learn how to work properly. Unlike their electric and battery-powered counterparts, gas trimmers not only need to mow the grass, but also start the engine.

How to properly mow the grass with a trimmer with a fishing line?

Practical garden tools are becoming increasingly popular. With the purchase of a new helper, questions are inevitable, how to properly mow the grass with a trimmer with a fishing line. To begin with, it is a great addition to your existing lawnmower. It can be trusted with large areas, and the finishing work will produce a grass trimmer with a fishing line. Let’s clarify, the line for the trimmer is designed to cut weeds and delicate branches. For rougher work, models equipped with metal blades or a chain are used.

Safety precautions during work

Technique work trimmer with a string and disk has some differences. A trimmer line cuts the grass at its tip, but if it is too fast, the entire length is used. As a result, the stems are not cut, but the grass is wound up on the cord, which overloads the engine. That’s why you should choose the best line speed. In addition, when mowing tall and tough grass, trimmer fishing line is consumed faster than when mowing the lawn.

There are a few simple recommendations that will make mowing more efficient and effective.

  • Garden paths, flowerbeds, edges of lawns are easily mowed with a bottom-mounted trimmer. The plane of rotation of the coil of such a device can be perpendicular to the ground.
  • Mow thickets, large weeds and bushes with the discs or special attachments.
  • When cleaning large areas, the tool should be tilted to the left, in the direction of swing.
  • To cut grass around flower beds, bushes and other objects, turn the grass trimmer head towards them. That way you can mow the objects and not damage them.

Remember that the bobbin or disk must not touch the ground or any obstacle other than grass or branches to be cut.

When working with brushcutters, safety precautions include.

  • Do not use your trimmer in rain or high humidity.
  • People and animals should be at least 15 m away from the working machine: grass clippings, small debris and stones fly out from under the cutting head at high speed and can injure people.
  • The grass trimmer operator should wear heavy clothing that completely covers arms and legs.
  • You need to work in protective goggles, gloves, headgear, closed shoes, special headphones or earplugs.
  • Grass trimmer’s lead must be behind the mower.

So, the use of manual devices for mowing the grass allows you to maintain order on a small area. It is more convenient to use a mower on large areas. In addition, the grass trimmer is relevant for making hay and tidying up the territory: small grass clippings can be mulched strawberries and other useful plants. You can visually see the mowing process with this tool in the video.

Mowing with a corded trimmer is safer, but not always as optimal as with a disc. As they say, it is worth choosing a cutting mechanism under the peculiarities of your area of work or use complex systems, where you can operate both the disk and the fishing line for the trimmer, if necessary, setting 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 “ejects” itself after each new start of the machine. This is very convenient, but not economical enough, for example, if your field is irregular in shape, and contains corners, jagged edges, and during the long transition to each of such areas the mechanism must be repeatedly turned 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 the device will mow. You can read the rules for threading the line in the spool in one of our articles, but the main thing to remember: the length of the line ends must be optimal for a competent mowing.

How to mow with a gasoline grasshopper correctly? This should be done so that it will last you as long as possible:

  • keep the reel 10 cm above the ground;
  • When working with tall grass. mow it at the top, and then at the stem to protect yourself from grass winding up on the device;
  • Lead the machine in the same direction in which the spool rotates;
  • Lawn grass, especially near walls and garden décor, is better to mow with the tips of a fishing 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 power tools.

Ideally, tall grass can be mowed with a powerful trimmer with a thick line. But, agree, the land where weeds grow. not always smooth, often landowners on the plots meet bushes and all kinds of debris, stones. To avoid wasting expensive equipment, it’s better to mow in two passes.

In a situation if you have to make grass for hay, and you are more or less familiar with the condition of the ground. then you can forecast your work easier. Any technique designed for mowing grass. can also cope with high overgrowth. The main thing is not to be in a hurry and to approach the process itself competently, as we demonstrate in a practical video.

  • Do not overload the mechanism;
  • If the grass gets tangled, turn off the unit immediately;
  • do not mow wet grass even with a gasoline trimmer.

Keeping and taking care of the trimmer

Gasoline grass trimmers require special care. In addition to cleaning and lubricating the cutting and rubbing surfaces from plant sap and dirt, you must also take care of the engine. The air filter is the fastest to get clogged. Its cleaning interval is about 10 hours. Sometimes the cooling ribs of the engine radiator also get dirty, which can cause the engine to overheat quickly, which can lead to seizure. How to clean the radiator and air filter is described in the manual on a particular gasoline trimmer.

Before leaving the grass trimmer for long-term storage at the end of the season, you should drain all the fuel from it, then start the engine and wait for it to stop. This ensures that there is no fuel in the tank and carburetor. After cooling the engine to unscrew the plug, pour into the cylinder of 30-40 ml of two-stroke oil, with a starter rope slowly turn the crankshaft so that it is distributed in all the cavities inside the engine, then screw in place the plug. After that it is necessary to disassemble the boom, if it is dismantled, cover all metal parts that can rust with preservative grease and then store the grass trimmer in a place protected from moisture.

After finishing work with electric trimmers it is necessary to wipe the cables and extensions, and for battery trimmers it is necessary to put the battery on charging, because it is not recommended to store the trimmer even for a short time with discharged battery. it can lead to a fast breakdown. After that the head should be removed, because both the protective cover and the drum internals have to be cleaned. If this is not done, grass sap can dry out on them and cause the reel with the mechanism that secures the trimmer line to no longer function properly the next time you start it.

Preparing electric grass trimmers for long-term storage is much easier. The main thing is to protect them from moisture inside the control circuit and the motor, as well as from rust on unprotected metal elements with preservative grease. Make sure to charge the battery before storing it, then your grass trimmer will be as good as new in the spring.

Care of the appliance

For the lawnmower to serve you well and for a long time, you need to perform a number of maintenance measures.

  • The grass trimmer should be stored in a dry place.
  • After each use, the appliance must be cleaned of grass and debris.
  • The air filter and cooling grille on the motor gasoline trimmer for grass should be periodically cleaned in the way described in the instructions for the technique.
  • Check gearbox for lubrication.
  • Wires of electric trimmers must be intact, without cuts or cracks in insulation. Only plug appliances into the mains through grounded sockets.
  • All cables must be coiled after use.

If the gasoline grass trimmer is not needed for a long time, you should empty its tank, let it idle for combustion of residual fuel, lubricate the engine. The power harness should be disassembled and connections should be treated with preservative grease to prevent rusting. All details regarding storage and care are explained in the user manual, which can be downloaded in case of loss.

Also in the electrical equipment can be punctured ignition coil. In this case the lawnmower does not start or starts and runs intermittently and then shuts down, or does not start on “hot” at all.

Check the serviceability of the coil can be the same way you check the spark: unscrew the spark plug, lean it against the body of the grass trimmer. If there is no spark when the starter jerk, or it appears only once, it is necessary to change the coil.

If everything is all right with the electrics, check the carburetor.

On grass trimmers put vacuum carburetors. When disassembling, cleaning or washing it, be very attentive. in no case dismantle the lower part of the carburetor, where the primer is. The air filter (it is visible if you remove the protective cover from the carburetor) should be washed with detergents. The best is for washing dishes. After drying, put it back. Flush the carburetor with clean gasoline and blow out all the holes with a pump. The gasoline line filter is also washed, then everything is dried and reassembled. Usually after all the manipulation, the grass trimmer begins to work.

Thin rope instead of fishing line, is it worth putting it on the brushcutter??

This thought has crossed the mind of almost everyone who has mowed 10 acres of tall grass. At first glance, the idea seems good. The cable is stronger than the line, not as much wear and tear. However, not everything is so simple.

How to correctly run in lawn mowers and chainsaws.

Mechanical. to defend and store gasoline for work not in a metal container and not longer than 1 (one) month, otherwise it oxidizes and loses its properties;

chemical. no impurities and additives must be present (they have different speed, degree and temperature of combustion). Old gasoline turns yellow or red; the impurities emit strong odors of bitterness (such as creosote) or acidity (such as methyl alcohol).

The fuel mix ratio is 1:50 (2%) or 20 ml/cm3 oil per 1 liter of gasoline. For example, pour half a measure of gasoline into a clear plastic bottle (1 liter), then use a medical syringe (20 ml/cm3) to inject the two-stroke oil and mix, add gasoline and mix thoroughly. If the quality of gasoline is doubtful or working conditions are difficult, you can increase the amount of oil to 22-25 ml/cm3. Shake the mixture before each filling! Store the fuel for no more than two weeks! If the color of the mixture has changed (from a sea wave color to brown, for example), it is not recommended to use it!

Start the lawnmower’s running-in period

After starting, do not rush to run the grass trimmer immediately. Let the engine idle for about 5 minutes to warm up. Adjust air flow with air regulator while the fuel is warming up so that the bobbin with fishing line or blade does not rotate. As soon as the tool is warmed up, let’s open the air supply by moving the lever to “ON” position and squeeze the throttle trigger 1/2 way for about 2030 seconds. Then release the throttle and let the trimmer run at idle for 30 to 40 seconds. Keep mowing for 10 15 minutes in such regime. Then we stop the engine and we give 15 20 minutes rest.

Having cooled the lawnmower, we continue to make a run-in of the engine according to the previous scheme. Start the grass trimmer when it is hot and with the choke open. Try not to hold the gas for too long, because the moving parts of the tool will only rub against each other. And do not allow the engine to idle for a long time because it can overheat.

The next step is running in of reducer of gasoline grass mower. For this purpose it is necessary to choose a site with soft young grass. We mow for 510 minutes with halftwo-thirds of full throttle. After a break for 20 25 minutes. Repeat the cycle 34 times.

In general, the lawnmower runs in accordance with the described algorithm until the fuel mixture in the tank is fully exhausted. After that the tool is ready for continuous work. Monitor the temperature of the gearbox and motor during operation. They must not overheat.

Servicing the brushcutter (grass trimmer)

Motor. Always keep the air filter clean (no dirt or shavings) and the foam filter wetted with oil. Check the fuel filter once a week and change it if necessary, if the machine is used a lot. Check nuts and screws for tightness. before starting work. Clean the muffler (or muffler gauze) and plug as necessary.

Cutting blades. Cutting edges must be well and correctly sharpened using the necessary templates and files (emery boards), observing the cutting angles depending on the type of disc. Double-sided blades should be turned 180° at regular intervals and worn evenly. A blunt disc or a disc that has been badly or improperly sharpened will not cut properly and will overload the motor thus accelerating the loss of motor service life.

Trimmer line and trimmer heads. Use only mowing line designed for trimmers. do not use wire or metal cords! Install only a line of the same size as recommended by your trimmer manufacturer. Wind the bobbin tightly but not over the coils. Clean and lubricate mower head if necessary. A worn or deformed head may damage the gearcase and/or shaft of your brushcutter.

Angular gearbox. Clean off dirt as needed (this “coat” prevents proper cooling of the Geareducer) and apply Husqvarna or similar grease to the gear train.

Protective guards. Never operate your brushcutter without its protective guards. danger to life and limb and risk overloading the brushcutter‘s engine. Use only the blade guard specified by the manufacturer for each type of cutting equipment.

Do-it-yourself hedge trimmer repair

It should be noted that it is not always possible to repair a brushcutter yourself, but in most cases, small repairs are within the power of everyone.

If the grass trimmer motor breaks, but you are not an auto mechanic or an electrician, it is better not to try to repair the mechanism. You might not be able to reassemble it yourself. The following problems are possible: low engine compression, the engine is jammed or the carburetor is defective. If these words do not tell you anything, you should not repair brushcutter by picture and intuition.

It should be noted that the maintenance and repair of chainsaws and brushcutters are similar in many ways.

A grass trimmer consists of a shaft, a motor (sometimes at the top or bottom), and a mowing head with blades, various additional elements. What can be repaired by yourself?

air damper; 2. handle; 3. engine stop device; 4. throttle control lever;

limiting bracket; 6. boom; 7. cutting attachment protector;

1) If the on/off rocker switch is stuck and you know about simple wiring diagrams and are good with soldering iron, solder and rosin, you can easily replace the rocker switch with a new one. You can buy them at electrical or lighting fixture stores.

2) If the wire restrictor on the mowing head has fallen off, it can be taped to the cutting head with a piece of flexible copper or aluminum wire. You can also make a new attachment from a strip of stainless steel.

3) If the trimmer line breaks in the mowing head reel, nothing is easier than replacing it yourself. You can, of course, just buy a head for brushcutter separately and replace it, but the line for the trimmer will definitely be cheaper. Optimal material is a 0.9 to 1.5 mm trimmer fishing line, nylon or kapron. Measure the diameter of the line you’re using right away, before it runs out completely. Thinner may tear, thicker causes overheating of the engine and unnecessary vibration. You need to disassemble the drum and wind the line for the trimmer by hand, then reassemble the drum.

4) If the bar breaks, it can also be repaired by taping and gluing to wooden laths or iron brackets.

5) If the engine is starting to vibrate strongly and is running rough, you might need to lubricate your brushcutter. Any trimmer for grass is easy to disassemble, it is recommended to lubricate it with technical oil at least once a year.

7) If the grass trimmer is equipped with plastic knives, and they are deformed for some reason, there is a way to replace them with metal ones. To do this, you need to make several blades of stainless steel. It’s a bit difficult at home, but the situation can save a turner you know, working at an industrial plant or factory. The knives are attached to the shaft with a sleeve with a washer. Such an upgrade will lead to the fact that the trimmer will be possible to mow grass of any hardness. But caution when dealing with such a trimmer is worth.

8) The engine doesn’t start? To start the brush, sometimes even a hot one, it is necessary to fully close the damper to enrich the mixture. Check the oil flow, clean the spark plug, replace it if necessary.
