A motokosa, in another way called a benzokos, is now available in almost any summer cottage. Its purpose is to cut grass and other vegetation quickly and accurately. Domestic brushcutters do not produce as loud sound as petrol cutters designed for public places.

The scheme of the brushcutter device resembles a bar, where there are blades cutting grass on both sides, a gear unit in the middle from below, and a power unit on top. All this is controlled by a long handle, which is easily adjustable.

Detailed description of the components of the petrol brush

The internal combustion engine runs on engine oil and gasoline, the minimum power for these household engines is from 0.5 horsepower to 2.5 horsepower. The productivity of work will always depend on the volume of the cylinder: the larger the volume, the higher the power and speed of work. That is, the fuel consumption for different brushcutters will be approximately the same, just a low-power brushcutter will have to be refueled after a short period of time. On average, a standard suburban area requires a petrol cutter with a cylinder volume of 40 cm3.

The rod is of no small importance in the device of the scythe - it is a rotational element and is responsible for the rotation of the wheels with blades. Brushcutter bars also come in different shapes and sizes. For home, braids with non-separable large rods are used, and for mowing in the area of ​​trees or parks, they often acquire a curved rod. Collapsible rods are profitable to buy when using different attachments for the braid.

As for the gearbox, it is like an adapter between the blade and the rest of the braid. Made of metal and steel, screwed with gears. The blades are screwed onto the braid. But for safety, washers are attached to the surface of the blades. They protect sufficiently fragile blades from breakage when hitting the ground.

Note! Elements such as a handle, trimmer and brushcutter fuel priming primer are minor but irreplaceable parts.

Spare parts and components for Chinese brushcutters

If you decide to immediately buy spare parts for the brushcutter, in order to instantly replace it in case of a malfunction, it is worth purchasing an additional set of electrical system, motor and cutting group. Of course, you can get the hang of it and sharpen the brushcutter knife several times, but upon impact, the blade may break, and then it will definitely have to be sent for replacement. This often happens when there is a foreign body in the grass, such as a stone or some hard object.

The scythe frame can break in the same way. At the same time, on brushcutters it is periodically necessary to change the carburetor and filter. Starters, belts for brushcutters and trimmers wear out quickly enough, he is responsible for starting the device. It is necessary to choose an additional set when buying a brushcutter. When a part breaks down, it will be harder to find the exact same part.

What spare parts for brushcutters can be useful for minor tool repairs at home

Small home repairs typically require the following parts:

  • piston rings;
  • separators;
  • split rod shafts;
  • gas handles;
  • cylinder gaskets, etc.

If you have experience or instructions, then these parts in the braid can be changed with your own hands. Purchases of such tools are carried out in a specialized store and often fit different types of equipment. Modern high-quality devices are quite easy to assemble and serve for a long time, sometimes even longer than a “native” part. And thus a brushcutter can last for many years, if you always change parts in it if necessary.

Important! Often, minor repairs require additional tools and parts, which everyone probably has in the country. For example, a soldering iron to mount a start button and a spring. It is minor repairs that can be trusted for self-assembly. The biggest important parts, like the trimmer, are best left to a professional.

Together with all of the above, the barbell is quite easily repaired. It is enough to wind it or stick it in the right place. Two common cases of minor faults are control complexity. If vibration has become strongly felt, and the process of oblique control has become more complicated, then lubrication is simply necessary. It provides a good and smooth grip. And if the scythe does not start (whether manual or automatic), you need to add gasoline. These problems are encountered by beginners and inexperienced brushcutter users. With experience it becomes clear when it is necessary to lubricate or add gasoline.

The brushcutter line will run out periodically. Therefore, a set of lines must also be purchased in advance. And the line must be of a certain diameter. If its diameter is larger, then the line will cause overheating of the engine, and if it is thinner, then it is highly likely that it will simply break. To put a new line, you need to disassemble the drum, then wind the line with smooth movements and assemble the drum back. How to wind the line on the brushcutter can be found in the braid's passport or on the Internet.

Maintenance and troubleshooting

To make the brushcutter last as long as possible, you need to properly care for it and use it according to the instructions. Gasoline and oil are mixed in a 1:25 ratio of oil and gasoline, respectively. Also, it is not recommended to save on oil and gasoline by increasing the proportion of oil relative to gasoline, or buying cheap and not pure gasoline, the same applies to brushcutter oil. The brushcutter gearbox is also regularly lubricated and checked for serviceability. Lubrication of the brushcutter gearbox takes very little time.

Note! The most important part is the brushcutter engine. In the design, it is divided into foam rubber (requires lubrication on average, once a week) and air (requires timely cleaning from various files and debris). The candles are changed periodically and the nuts are tightened.

For the cutting disc to last longer, it must not only be sharpened, but also turned upside down. The fact is that one side wears out faster anyway. And the more often you turn the disc, the longer it will last. It has already been said about the line above, but it can be added that instead of the mowing line, you cannot use others, for example, wire.

It is forbidden to work with an oblique blade with a blade without guard for the following reasons:

  • this is a serious danger to the life and health of the summer resident himself and those who are nearby;
  • this is an additional stress on the braid device, which means that it wears out faster and breaks more often;
  • the work process itself will be more difficult, and the device will become clogged with excess grass.

A motocross is a simple device, but for a long service it needs proper care, control over when the scythe needs to be lubricated and sharpened.
