grass trimmer. Types and construction. Operation and how to choose. Safety

Garden equipment about, which will be discussed, consists of four main elements: the engine (electric or gasoline), a long boom, control handles, cutting head. Due to differences in translation, these devices often appear under different names: grass trimmer, grass mower, lawn mower, electric lawn mower, electric mower, haymower and even lawn mower. This creates confusion. Lawn mower. a device for lawn care, the main purpose is to maintain a neat appearance of the lawn.

The term electric lawnmower refers to two types of engines at once. gasoline and electric, which is also not quite right. In fact, all types of mowers more logically called trimmers for grass, which are divided into electric (electric mowers), gasoline (brush cutters or lawn mowers) and battery.

There’s also no mistaking that lawn trimmer is a tool for creating decorative lawns. To mow the area inaccessible to the lawnmower grass trimmer can. However, it is unlikely to mow the lawn evenly with a grass trimmer. The lawn processed in such a way will be inferior in appearance to the result of work with a wheeled mower. But to mow thickets of weeds with a trimmer can be easy and pleasant.

Getting to know the tool

The question of how to mow with a gasoline grass trimmer is mostly posed by beginners, who have recently acquired these tools. Before proceeding to perform the work, it is recommended to learn the design and construction of the lawnmower. The main structural elements of the tools under consideration include:

  • Gasoline 2-stroke engine. There are tools with 4-stroke engines, the disadvantage of which is their large weight
  • Fuel tank. a container for storing diluted gasoline and oil
  • Gearbox. the transmission mechanism by means of which the torque is transmitted from the engine shaft to the executive body
  • Starter. a device for starting the gasoline engine
  • The boom is the rigid base that connects the engine to the implement

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

Know the construction of the tool in order to learn how to work it correctly. Unlike electric and battery-powered counterparts, gasoline-powered trimmers not only need to know how to mow the grass, but also how to start the engine.

This is interesting!To start the electric grass trimmer, you only need to press the start button, and the start of the gasoline unit is carried out through the use of the starter.

Manufacturing companies produce the following models of mowers:

  • On which the gasoline engine is installed. Such garden tools have a fuel tank, this is their distinctive feature.
  • Devices with an electric motor. These tools have less weight, because they do not have a tank for fuel. But when choosing these models, you need to consider that they need a power supply to work.

How to use a trimmer correctly

Grass trimmers are efficient. Beginners think that operating a lawnmower is easy, because you only need to plug it in or pour fuel, but that’s not quite true.

After that move on to installing the cutting system. There are grass trimmers on sale for low power, which use only a line for the trimmer. It is designed for mowing juicy and soft grass. But there are models with more than 1 kilowatt of power that are fitted with metal knives. They cut thistles and other tough weeds, trim young shrubs.

To replace the cord with knives, unscrew the fastening nut, install the cutting element. Then put the nut back in its place, tighten it with the key.

The operator has to be concerned about his safety. The grass should be mowed in tight protective clothing. Use special goggles to protect eyes from dust, grass and flying debris. Hands should be covered with gloves.

Electric grass trimmer is plugged in, and cordless models are charged for several hours before operation. The gasoline mower is filled with fuel.

  • For rougher grass and thickets you can use one of the metal blades, which differ from each other in the number of cutting teeth.
  • For mowing dense undergrowth, reeds, young growth. disc with 40 or 80 teeth. Corn, dry weeds with thick stems can be mowed with three- and four-blade mowers.
  • And for laying the cuttings in swaths a blade with 8 blades is used and a special comb is attached to the mower itself.

And now more about how to install the burr. The place where you attach the cutter is called a gearbox. On it, you must first secure the shaped washer with an Allen key.

Then place the blade, aligning the holes in it with the protrusion of the washer. After that, you need to install the top shaped washer on the shaft and tighten everything with the nut.

The line for the trimmer also has its secrets

The line for the trimmer is wound on the bobbin inside the spool with the spool tips facing outward. When mowing, the bobbin rotates and the trimmer line, as it rotates, cuts the grass. To release the tips of the need to lightly bump the spool on the ground (the system. semi-automatic), there are coils, automatics, which have a line to trimmer itself released. There are also a few rules when working with the line:

To avoid damaging the trimmer line and spool. Try not to touch hard materials like paths, curbs, fences with your spool and fishing line. Doing so shortens the trimmer line prematurely, can damage the spool or even jams the engine. The line bobbin must not touch the ground either.

Mow with the tips. it’s more efficient. If you mow the entire length of the line, you may overload the engine. This also lowers mowing efficiency. Hold the tool so that it only mows with the tip of the line. To do this, tilt it forwards, towards the mowing direction.

Tall grass needs several cuts. If the grass is over 20 cm in height, mowing is not enough. You need to mow two or three times, from top to bottom. This is done to prevent grass from getting wound up on the reel. Grass on a bobbin means overheating of the engine. If grass does coil up, you need to stop the tool and clean it.

the line for the trimmer has run away and hides in the reel. This can happen at work if you do not let the line for the trimmer out of the reel in time. Because trimmer lines wear out and shorten during mowing. If you don’t have time to let it out, stop the engine, unplug the tool, then disassemble the bobbin and run the ends of the line through the proper holes.

What line consumption depends on? Keep in mind that trimmer lines wear out faster if the grass is tough. So you need to let it out more often when mowing weeds and dry tough grass. Around the foundation of the house, near the wall and the curb, the consumption of the line will also be more than directly on the lawn or near trees. Consider: if you work carefully and carefully, your line will be optimally and economically consumed.
