How to put the protection on Trimmer
The right choice of brushcutters for quick, and most importantly effective cleaning of the territory from unnecessary vegetation should be determined with some indicators. Motokosa have gained popularity in agriculture, in the communal sector. Convenient and mobile unit suitable for periodic, seasonal work on a personal plot. With its help get rid of tall grass, woody weeds, bushes. Three types of motokos are considered: professional, semi-professional and household. A professional machine is used for haymaking, putting the territory in order. Semi-professional devices are in demand by representatives of various professions: designers, professional gardeners, landscape designers. A household device is most often used in summer cottages where it is necessary to process flower beds and a lawn, clean paths and cut weed along fences and houses. The design for all motokos is the same: a rod, an engine and a mowing head are fixed on it. We have collected 10 important points that will help you easily choose a motokosa.
1. Two or four stroke engine?4-stroke internal combustion engines involve working with gasoline and oil. Over, gasoline is in one tank, oil in the crankcase. Such models are distinguished not only by their greater cost, but also by a large work resource, increased reliability with a sufficiently large weight. Of the advantages of 4-stroke motokos, their reduced vibration and low sound pressure level are noted. 4-stroke drives are designed for lower gasoline consumption, which indicates their efficiency.For a 2-stroke motokosa, a mixture of gasoline and oil is pre-harvested. Oil for lubricating the necessary mechanisms, in this case, is used from the resulting mixture. It must be borne in mind that the mixture cannot be stored for a long time, therefore, during long breaks it must be drained. Of the advantages of a 2-stroke engine, it is worth noting the small size and light weight, which must be taken into account when determining who will work with the equipment.Both those and other units are characterized by increased performance. The durability is dominated by a 4-stroke engine. Both types of engines require special maintenance, fuel preparation, oil filling, that is, careful attention. The user can work early in the morning, when the grass has not yet dried from dew and after rain, when the grass is still wet. The mobility of the device expands the capabilities of the owner. The operator can go anywhere far away from home. Refueling and oil can be done directly at the workplace.
2. What power is enough?The high engine power of the hand tool plays an additional advantage for professional units, as productivity increases. For a household unit, more power translates into unnecessary expenses for increased fuel and oil consumption. Increased vibration for the operator threatens with greater effort during operation, which means more fatigue. The greater weight of powerful devices, again, creates additional physical stress on the user’s muscles. An engine power of 1 kW is enough to work on a standard site of 5-10 hundred parts.
Professional devices have engine power from 1.8 hp, some models are equipped with an automatic system that regulates power, increasing it in difficult areas and reducing it in an open area.
3. The number of revolutions of the cutting system. It is very important!The optimal combination of engine power and its maximum number of turns. This is the main indicator when choosing a brushcutter. In modern systems, there is a special mechanism that allows the braid to tune to the desired mode, and the unit selects the desired number of revolutions of the cutting tool, almost instantly. The high speed of the cutting blocks, this is a cleaner cut that does not damage the stems of plants and is the best guarantee for the growth of healthy grass.
5. The belt is responsible for the load on the arms and back
Shoulder straps are used to hold the tool in hands during operation. The weight of professional motokos reaches 7 kg. If the load is correctly distributed on the shoulders and back of the user, then he gets tired less and the work itself is very comfortable. Belts can be worn on the shoulder. This is one option, one side of the user is involved. The second, more preferred, knapsack vest. With its help, the weight is evenly distributed on two sides. As a result, the operating time increases. Physical activity on muscles decreases. When performing a large amount of work, you should choose exactly the last type of weight distribution of the manual device.
7. What is the shape of the bar?Types of booms. A curved rod inside itself encloses a flexible shaft, which has the appearance of a cable. The flexible design perfectly absorbs during unexpected blows of a knife against a stone or other hard object, which guarantees protection of the gearbox from breakage. A curved bar makes it easier to get to plants under benches, between trees, flower beds.
The straight rod contains a metal pin (hard shaft) inside. Such a shaft rotates without friction on bearings, withstands severe loads, does not lend itself to deformation, and copes with dense growth.
8. Collapsible or solid shaft?
Convenience of a braid with a folding bar consists in more comfortable transportation. Dismantled and put in the trunk or put into storage until next use. The tool takes up less space. It is believed that a collapsible shaft over time causes more play, a gap between the two structures. But modern manufacturers reject this opinion. High-quality compounds do not loosen over time, and the convenience of storing them is greater. And to assemble the tool quickly and easily, the assembly takes only a couple of minutes.A direct bar is harder to transport. Inside the straight pipe is a shaft that transmits torque to the cutting unit. The design of the braid with a non-separable shaft completely eliminates the ingress of foreign particles, dust and dirt, which makes the unit safe for use.
To facilitate the design, modern manufacturers use aluminum (instead of steel), which, with maximum structural rigidity, provides minimum weight, which means greater comfort. Steel construction is a more familiar material, it makes the instrument heavier, although it costs significantly less.
